Do GLP 1 patches work? The ultimate guide
Before you trade your doctor’s prescription for a TikTok-famous "weight loss sticker," let’s look at the science behind why those needle-free patches might be leaving your results—and your wallet—a little thin.
Key highlights
- Commercially available “GLP-1 boosters” or “GLP-1 patches” are not FDA-approved and do not contain GLP-1 molecules. In contrast, GLP-1 injectables, such as Ozempic, Wegovy, Zepbound, and Mounjaro, are prescription medications that help with weight loss in obesity and diabetes management.
- Currently marketed “GLP-1 patches” contain herbal ingredients that have shown improvements in metabolism and appetite suppression in individual studies, yet no clinical trials or research show their significant combined effect in weight loss.
- Transdermal patches are being tested and developed for different medical applications, making way for FDA-approved GLP-1 transdermal patches in the future.
- Do not try any new medication without consulting your healthcare provider. Even minor mistakes could lead to serious consequences.
Ozempic, Wegovy, and Mounjaro are no longer news. These incretin mimetic GLP-1 and GIP/GLP-1 drugs that help you lose body weight by slowing down digestion and increasing the transit time of food in the stomach have gained widespread popularity in the past half a decade.
While the world is not yet over GLP-1 injections and tablets, there’s a new trend everywhere: “GLP-1 patches.”
GLP-1 patches gained the spotlight pretty soon, thanks to aggressive social media marketing. Instagram and TikTok are loaded with videos of influencers and users claiming how these GLP-1 patches are helping them curb their cravings, as well as those calling these skin patches a scam.
So, what’s the truth: Do GLP-1 patches actually work, or are they a waste of money?
Though these GLP-1 patches claim to mimic the action of GLP-1 drugs and support weight loss, they do not contain glucagon-like peptide-1 (GLP-1).
This article shares all the details on GLP-1 transdermal patches, their ingredients, who they can help, whether they really help you lose weight, and the future of transdermal drug delivery systems for weight loss.
What are GLP-1 patches?
GLP-1 patches are OTC (over-the-counter) transdermal patches that claim to deliver GLP-1 drugs through the skin.
These patches claim to use a slow-release transdermal technology that delivers the drug into your bloodstream through the skin, gradually. GLP-1 patches without microneedles cannot transfer the drug through the skin.
While their name may cause people to assume they are patches containing semaglutide, tirzepatide or another GLP-1 drug, it is worth noting that the currently available GLP-1 patches contain herbal supplements, not GLP-1 agonist drugs.
The science behind the patch
Transdermal patches are widely used in healthcare for pain-free, controlled, or consistent drug delivery. For example, nicotine patches help with smoking cessation, whereas fentanyl patches deliver controlled doses for pain relief. These patches work because of the size of the molecules that can easily pass through the skin.
The outer layer of the skin, Stratum Corneum, is around 10–20 µm (very thin), but it is the main barrier for drug penetration.
For a drug to passively diffuse through this layer, it typically needs to be:
- Small in molecular size
- Lipophilic (fat-soluble)
However, GLP-1 molecules:
- Are too large and hydrophilic
- Cannot naturally penetrate the skin barrier
Even if GLP-1 patches claim to have GLP-1 drugs, the molecules cannot pass through the skin barrier without support.
To bypass the skin barrier, several support techniques are being studied, such as:
- Microneedles: Tiny needles create microchannels in the skin, allowing drugs to enter the bloodstream directly. This is the most widely researched transdermal drug delivery system.
- Iontophoresis: Uses a mild electrical current to push charged molecules through the skin.
- Sonophoresis: Uses ultrasound waves to temporarily disrupt the skin barrier.
- Thermal ablation: Applies controlled heat to create microscopic pathways for drug entry.
What are the ingredients in GLP-1 patches?
Weight loss patches, widely marketed as GLP-1 patches, are a combination of plant-based compounds and micronutrients. They do not contain any of the GLP-1 drugs.
These skin patches are often promoted as “GLP-1 boosters,” and some have labels referencing the term “GLP-1 patch,” when they do not clearly contain any GLP-1 agonist drug.
The ingredients commonly used in GLP-1 patches include:
Berberine
Berberine, also known as “Nature’s Ozempic,” is a natural appetite suppressant found in barberry, oregon grape, goldenseal, and other plants.
A review of multiple studies concluded that individuals taking berberine reported a significant reduction in body weight and BMI. Besides its popularity for weight loss, berberine is also being studied for its effect on diabetes and heart disease risk factors.
Individuals taking berberine might experience gastrointestinal side effects, including abdominal pain, bloating, diarrhea, constipation, and nausea. Reactions with drugs such as cyclosporine have also been recorded. So far, berberine can be administered only via the oral route.
Green tea extract
Green tea is known to improve metabolism and is often taken after meals in different cultures.
Catechins and caffeine in green tea are believed to have a role in increasing energy metabolism, which may contribute to weight loss. Research shows that green tea extract reduces low-density lipoproteins (LDL) in overweight and obese women after six weeks of treatment. No significant changes in other weight-related biochemical markers were observed.
Another study showed that obese and overweight patients showed improvement in body mass (BM) and body mass index (BMI) compared to individuals with normal BMI. The change in body weight may result from the inhibitory effect of green tea extract on ghrelin (a hunger hormone) secretion.
Research has further exhibited the possibility of small amounts of green tea extracts passing through the skin via adhesive patches. However, evidence-based data show the weight loss efficacy of tea extract with patches.
Garcinia cambogia
Garcinia cambogia is known for its fat metabolism properties, reducing abdominal fat accumulation in individuals with visceral fat accumulation type of obesity. Hydroxycitric acid in Garcinia cambogia has been seen to be beneficial in fat and weight loss.
A systematic review and dose-response meta-analysis showed that the Garcinia cambogia supplement significantly reduced BM (body weight), BMI (body mass index), PFM (percentage of fat mass), and WC (waist circumference). Long-term (6 months) treatment with Garcinia cambogia resulted in weight loss, an increase in basal metabolism rate, and a reduction in visceral fat, lipid, and blood glucose.
Findings in different studies indicate that Garcinia cambogia and Glucomannan therapy in individuals with overweight or obesity (across varying ages, sexes, and metabolic conditions) led to meaningful improvements in body composition and metabolic health. Participants experienced reductions in body weight, total fat, visceral fat, blood glucose, triglycerides, and cholesterol, alongside an increase in basal metabolic rate, with no reported adverse effects.
Cinnamon and Chromium
GLP-1 alternative patches may contain cinnamon and chromium to mimic the anti-diabetic action of these drugs.
Research conducted in animals and individuals with metabolic syndrome, type 2 diabetes, and polycystic ovary syndrome suggests that chromium and cinnamon in its whole form, and water-based cinnamon extracts can positively influence blood sugar control. They improve insulin function, increase insulin sensitivity, lipid levels, and antioxidant activity.
Cinnamon has been seen to be beneficial in diabetic patients with HbA1c levels higher than 8%.
Some reports also conclude potential improvements in body composition, including lean mass. A study showed that 12-week treatment with cinnamon (500 mg/day) decreased the percentage of fat mass and increased lean mass, improving overall body composition.
Overall, the effects of these compounds on fat metabolism, body mass index, lean mass, and insulin sensitivity might show changes in body weight on long-term treatment, yet they are less likely to offer the same results as GLP-1 patches.
Why are the patches becoming so popular?
GLP-1 medications, including subcutaneous injections and tablets, have been a hot trend, followed by this new “GLP-1 patch” social media phenomenon. The combination of “fast weight loss” and a “needle-free experience” has everyone talking about GLP-1 patches everywhere.
1. Eliminating needle anxiety and discomfort
Needle anxiety and discomfort may seem like an excuse to avoid getting an injection, but it is very real.
Research shows that 20–30% of young adults report needle fear. Another survey conducted to understand the prevalence of needle phobia in adults concluded that 63.2% of adults experienced some degree of needle phobia.
This can make it challenging for adolescents and adults with needle anxiety to start their GLP-1 weight loss journey.
In such situations, GLP-1 patches can be a game-changer in eliminating needle anxiety and offering better comfort for patients.
A survey studying safety, efficacy, patient compliance and cost-effectiveness of transdermal, oral and intramuscular pain medication showed that all the patients experienced pain on injecting the drug. Patients in the transdermal patch group reported generally better overall satisfaction with pain relief and ease of use. In another trial, 87% of the participants preferred transdermal patches over oral medication, showing the need for transdermal drug delivery systems (TDDS) for GLP-1 drugs.
2. Convenience and lifestyle integration
Administration and storage are two of the most significant concerns of GLP-1 injections, for which GLP-1 patches offer a convenient solution.
Most people on GLP-1 medication use subcutaneous injections, administered into the stomach, thigh, or upper arm, once every week. If not stored correctly, GLP-1 injections can become unsafe for use, leading to loss of money and missed doses. Transdermal patches solve both issues.
Patches are non-invasive and easy to apply. You can wear the patch on your stomach, thigh, upper arm or back, making it discreet.
While you might need to reapply these “GLP-1 booster” patches more often than subcutaneous pen administration, transdermal patches do not require refrigeration, unlike subcutaneous injections. You can store them at room temperature and carry them during travel without any additional considerations or effort.
3. Steady, continuous delivery
Though injections provide better bioavailability than oral medication, bolus administration leads to a peak concentration of the drug in the bloodstream. Transdermal patches offer continuous drug delivery, ensuring steady levels of the active ingredient in the bloodstream.
This controlled and consistent drug delivery also helps reduce systemic side effects by eliminating peak concentrations on bolus (injection) administration.
4. Accessibility and administration considerations
Transdermal patches can be an ideal choice for patients with needle anxiety or injection administration issues. Patients can easily apply and remove the patch without the need for injection training.
Easy application eliminates the fear of incorrect administration, improving accessibility and self-administration confidence. This also encourages healthcare providers to prescribe the medication with fewer administration concerns.
5. Potential for improved adherence
Patients taking transdermal patches have exhibited better adherence compared to other administration routes. Research on patients using transdermal patches for neurological conditions concluded that adherence rates increased to 85.9% gradually, with patch users more likely to continue treatment than those on oral medication.
Additionally, studies on microneedle patches also suggest that non-invasive patch administration may improve adherence in chronic therapies.
Risks and side effects
Despite containing ‘natural’ or ‘herbal’ ingredients, these commercial GLP-1 patches are not approved by the U.S. Food and Drug Administration (FDA), and have no proof that they actually work as well as GLP-1 oral medications and injections approved by the FDA.
Patients using transdermal patches (with or without GLP-1 drugs) may experience reactions to the transdermal patch. Applying the patch for longer periods can lead to side effects such as:
- Erythema (redness)
- Pruritus (itching)
- Contact dermatitis
- Skin inflammation
- Burning sensation
GLP-1 transdermal patches may also cause hypersensitivity reactions and skin sensitization after repeated exposure. The absence of FDA-approved GLP-1 patches also increases the risk for unexpected side effects and adverse reactions.
Commercially marketed weight loss patches may contain stimulant ingredients, including caffeine and bitter orange (Citrus aurantium). Caffeine increases alertness and can increase heart rate and disturb sleep patterns, leading to insomnia. Another common stimulant, bitter orange, causes jitteriness or nervousness, increased heart rate, heart palpitations, and elevated blood pressure.
In the future, patients using GLP-1 patches with GLP-1 or GIP/GLP-1 molecules may experience the side effects of GLP-1 agonist drugs, such as constipation, diarrhea, vomiting, abdominal pain, gallbladder disease, pancreatitis, kidney injury, and hypoglycemia.
GLP-1 patches vs GLP-1 injectables
| GLP-1 patches | GLP-1 injectables |
|---|---|
| Transdermal patches | Subcutaneous injections |
| Continuous delivery | Bolus administration (at-once injection) |
| Once daily application | Typically once-weekly administration |
| Risk of inconsistent delivery | Accurate dosing |
| Painless | Mild pain or stinging on injection |
| Better patient adherence | Inconvenient for people with needle anxiety |
| Does not contain GLP-1 drugs yet | Contains GLP-1 drugs |
| Not FDA-approved yet | Semaglutide, tirzepatide, liraglutide |
| Unsure efficacy and safety | Wide clinical trials and research available |
| Unregulated manufacturing and selling | Prescription only |
| No proven weight loss | 15% weight loss reported on average |
Efficacy: Will patches work as well as injections?
Subcutaneous injections deliver the drug directly into the bloodstream, ensuring immediate bioavailability, whereas transdermal patches continuously deliver the drug through the skin.
The outer layer of skin, stratum corneum, only allows small molecules, under ~500 Daltons, to pass through it. GLP-1 receptor agonist drugs are large peptide molecules, around 3,000-4,000 Daltons, making the weight loss efficacy of GLP-1 patches ambiguous.
Because of this reason and challenges in dose regulation through patches, the FDA has not approved transdermal patches for GLP-1 drugs yet.
Patients using commercially available weight loss patches have mixed opinions about the efficacy of the patches. One user on Reddit mentioned, “They do work! I’m on week 2 and have lost 4 pounds, and I notice I’m not hungry or craving anything. I have to remind myself to eat meals, would def recommend trying! I feel most people saying scam haven’t given them a shot. It’s a natural supplement to reduce your appetite, not actual GLP-1,” whereas another called it a “total scam.”
The lack of clinical trials and research on these GLP-1 booster patches makes it difficult to evaluate whether these patches actually help with weight loss, or the hype could just be a result of the placebo effect in users.
Side effects: Similarities and potential differences
Weight loss patches currently available are not GLP-1 mimetics, and may not have the same side effects as GLP-1 drugs, like Wegovy, Ozempic, Mounjaro, or Zepbound. If the FDA approves GLP-1 weight loss patches in the future, patients using the patches may experience similar side effects as subcutaneous GLP-1 injections, including GI-related adverse effects.
| GLP-1 injections | Weight loss patches |
|---|---|
| GI-related side effects are common | GLP-1 patches may cause GI side effects |
| GI side effects include constipation, diarrhea, vomiting, nausea, and abdominal pain | Patients report bloating on using weight loss patches |
| Redness or mild swelling at the injection site | Redness, itching, or irritation at injection site |
| Local inflammation or tenderness may occur | Contact dermatitis, rash, or allergic reaction to adhesives possible |
Cost and insurance coverage
GLP-1 injectable drugs cost between $300 to $1,000 per month without insurance. In comparison, commercially available GLP-1 patches cost $10 to $25 for a 30-day supply (without insurance).
| Factor | GLP-1 injections | Weight loss patches |
|---|---|---|
| Approved uses | FDA approved for blood glucose management & weight loss | Not FDA approved yet |
| List price | $300-1,000/month | $10–$25/month |
| Cost with insurance | $25–$300/month | N/A |
| Insurance coverage | Typically for FDA-approved uses | Likely similar to GLP-1 injections |
Most insurance companies provide coverage for FDA-approved uses, reducing the out-of-pocket costs significantly, and patients using GLP-1 injections may pay as little as $25 with insurance.
As GLP-1 patches are not yet FDA-approved, they will not be covered by insurance.
In the near future, FDA-approved GLP-1 patches may become readily accessible to patients at even lower out-of-pocket costs. Insurance providers may reimburse patients with a prescription for the labelled use, which may require prior authorization.
Safer alternatives for non-injectable weight loss
If needles make you anxious and the search for a convenient alternative has you looking for GLP-1 patches, you might want to try these first:
- Oral GLP-1s: Oral GLP-1 drugs, such as Rybelsus and Wegovy Pill, can be excellent options for patients with needle anxiety. Rybelsus is a tablet-form GLP-1 receptor agonist manufactured by Novo Nordisk. While the drug is approved for type 2 diabetes management and cardiovascular risk reduction in high-risk patients with diabetes, it contains the same active ingredient (semaglutide) as Wegovy, but costs less than the injection. Your insurance might not cover Rybelsus for weight loss, but this oral medication delivers semaglutide efficiently, facilitating weight loss. Wegovy Pill is the oral version of Wegovy injection.
- Compounded medications: When searching for a more suitable GLP-1 medication without insurance, opting for a compounded medication may be the right choice. Compounded medications are made at specialized compounding pharmacies or FDA-registered outsourced facilities. If medically appropriate, telehealthcare providers can prescribe compounded oral GLP-1 medications for weight loss.
- Lifestyle foundation: GLP-1 drugs are prescribed as an adjunct to physical workout and a low-calorie diet. A protein and fiber-rich diet with a lower amount of carbohydrates and fats can be the perfect choice for healthy weight loss with GLP-1 drugs. Research shows that fiber reduces hunger and promotes satiety through several gastrointestinal mechanisms. However, a low-calorie diet along with GLP-1 agonist drugs can also lead to loss of lean mass, emphasizing the need for protein intake with resistance training to preserve muscle mass.
Who might benefit the most from GLP-1 patches?
FDA-approved GLP-1 patches could become the first choice of dosage form for obese and overweight patients with needle phobia or injection anxiety. It will eventually improve adherence among patients who struggle with injection administration.
Individuals with active travel schedules and those looking for a discreet weight loss treatment may also benefit from GLP-1 patches. Transdermal patches do not require strict storage conditions and can be applied to your body effortlessly.
Considerations for specific populations
Despite the adherence improvement and convenience of GLP-1 patches, they may not be the best option for some people, including:
- Elderly patients usually have frail skin, making it challenging to apply and remove the transdermal patch.
- Patients with dexterity challenges, such as arthritis, neuropathy, or other fine motor skills, may find it hard to apply and remove the patch themselves, requiring extra support.
- Individuals with certain skin conditions, like eczema, psoriasis, dermatitis, or severe scarring, might be recommended by their healthcare professional to avoid transdermal patches as their skin condition may worsen or influence drug delivery.
Latest developments on GLP-1 patches
Various pharmaceutical companies, particularly in South Korea, including Daewoong Pharmaceutical, are working on developing microneedle patches for GLP-1 drugs.
Daewoong Pharmaceutical
Daewoong Pharmaceutical is developing a semaglutide transdermal patch using their patented CLOPAM® (Closed-Packed Aero-pressured Microneedle) technology. It is a dissolving-type microneedle technology that offers skin-based, precise drug delivery.
Their microneedle patch reportedly has the highest bioavailability for semaglutide through a patch. The company has completed its phase 1 clinical trial application with the Ministry of Food and Drug Safety in South Korea.
In a pilot study, 70 healthy adults received either a subcutaneous semaglutide injection (Wegovy) or a microneedle patch containing the same drug. The reported results are promising:
- Over 80% relative bioavailability
- Around 160× higher bioavailability vs oral tablets
- Sustained drug levels for ~1 week (once-weekly dosing potential)
Additionally, the microneedle patches are stable at room temperature, eliminating the need for cold storage, unlike semaglutide injections. This will help reduce distribution costs and waste from syringes and needles.
Dong-A ST
Dong-A ST is a subsidiary of Dong-A Pharmaceutical, the oldest pharmaceutical manufacturer in Korea. Dong-A ST has partnered with microneedle specialist Juvic to develop a GLP-1 patch for weight loss and diabetes. Juvic focuses on transdermal patches designed to overcome the stratum corneum barrier.
The manufacturer has already developed a new patch-type diabetes treatment (egg microneedle) to overcome the limitations of existing dissolvable microneedles, exhibiting potential for successful GLP-1 patch development.
Raphas Co. Ltd.
Raphas is a drug delivery platform company specializing in microneedle technology. Being a leader in microneedling TDDS, their unique micro needle technology, “DEN (Droplet Extension Needle)”, allows them to transfer drugs through a ‘soluble micro needle.’ Raphas has FDA cGMP manufacturing validation for microneedle skin patches and has completed Phase 1 clinical trials.
Their microneedles are specifically designed to deliver macromolecules, including peptides, such as GLP-1 agonist drugs.
PharmaTher
PharmaTher is a Canadian specialty pharmaceutical company focused on developing psychedelic and peptide-based therapies. In January 2026, the company announced a strategic initiative to expand its PharmaPatch microneedle patch platform into select therapeutic peptides.
The microneedle patch technology uses a biocompatible and biodegradable gelatin methacryloyl (“GelMA”) material that penetrates the stratum corneum (outer layer of the skin) and supports controlled release delivery and flexible drug loading capacity.
Anodyne Nanotech
Anodyne Nanotech is one of the few pharmaceutical and drug delivery manufacturers with preclinical data on transdermal GLP-1 patches for obesity.
Jake Lombardo, Co-founder and CEO, Anodyne Nanotech, presented the preclinical data on the once-weekly GLP-1 patch at the 14th annual Partnerships in Drug Delivery (PODD2024) Conference in 2024. The results showed that the patch can achieve multi-milligram delivery, surpassing commercial semaglutide injections.
The once-weekly transdermal GLP-1 patch for obesity is set to enter clinical trials in 2026.
Though FDA-approved, safe and effective GLP-1 patches are not available, we’re not far from this breakthrough. These patches may improve patient adherence by reducing pain associated with injections and eliminating the need for cold chain storage.
The future landscape: Beyond weight management
The use of transdermal delivery systems is not restricted to diabetes management and weight loss in patients with obesity. The possibility of TDDS is being studied across different avenues, including hormone delivery, pain management, tissue regeneration, and other applications in health and wellness.
Potential expanded applications
As the development of GLP-1 patches is underway, many companies are working to determine accurate dosing and obtain FDA approval for their transdermal GLP-1 patches. It establishes the future path for delivering other peptide drugs through transdermal patches as well. Microneedle transdermal patches can potentially deliver the following benefits and more, if research and trials show feasible results:
Further advancement in the transdermal patch landscape could lead to the manufacturing of multi-reservoir patches, delivering numerous active ingredients at different rates.
Integration with digital health
The world is moving rapidly toward a technology-first approach, making it necessary to digitalize products for efficient monitoring and results. Smart patches represent one such advancement in this area.
Considering the improvements in nano material, small patches can understand the body’s immune response by analyzing microenvironments and biofluids. Smart patches have sensors and similar technologies that monitor the patient’s response to the medication and adjust the drug delivery accordingly.
Review analysis has shown that these patches offer continuous health monitoring, controlled drug delivery, modulation of nerve responses and support tissue regeneration.
Attempts have been made to design microneedle patches with biosensors to monitor patients and provide better efficacy. Currently, microneedle-based biosensors are used for glucose monitoring, therapeutic drug monitoring, chronic disease management, and fitness tracking.
A microneedle-based smart patch sensor platform has been developed for painless and continuous glucose monitoring for patients with diabetes. Another smart insulin-releasing patch consists of 121 microneedles to painlessly penetrate into the interstitial fluid between subcutaneous skin cells, whereas one smart patch made with conductive hydrogel patches monitors and treats diabetic foot ulcers, which is a common issue among patients with diabetes. Biosensors can also improve safety by ensuring accurate dosing and detecting any sudden physiological changes.
Additionally, digital twin technology provides customized, accurate therapy to improve the therapeutic outcomes and reduce risks in chronic pain management. Digital twin systems integrate physiological data with computational models to optimize patch application, dose adjustments, and drug absorption. Future research in integrating AI and IoT to improve digital twin applications in precision medication could be a transformative step.
The integration of AI and ML in transdermal drug delivery could be the next breakthrough, as it can predict drug entrapment with a 93% accuracy and improve formulation by forecasting drug release kinetics, stability, and skin penetration. It may also help identify permeation enhancers and novel drug candidates for advanced transdermal patches in applications, including diabetes, weight management, and others.
The Ategenos SmartPatch platform by Ategenos Pharmaceutical is another revolutionary TDDS technology. It monitors the patch from the very first step, ensuring proper tracking and timely intimation in case of a missed dose. The patch includes the medication along with built-in sensors and a communication interface. The sensors can detect when:
- The packaging is opened
- The adhesive cover is removed
- The patch has been applied
- The patch is removed from the skin
A wireless MCU within the patch switches between operating modes and sends usage signals via Bluetooth Low Energy that are interpreted by Ategenos cloud software. It uses the prescribing information to assess if a dose has been taken, delayed, or missed, and determine the next dosing. When a patient misses a critical dose, alerts are sent to caregivers’ mobile devices to avoid serious consequences and emergency room visits.
FAQs
Do GLP-1 patches help with “food noise”?
Studies show that GLP-1 drugs help reduce weight by improving satiety and decreasing cravings. While clinical studies on the efficacy of GLP-1 patches are not yet available, some patients using commercially available patches report reduced “food noise” and decreased hunger. However, these claims are anecdotal and should not be relied upon by patients.
Can I use the patches alongside my Wegovy or Zepbound injection?
While many patients are tempted to use a GLP-1 support patch alongside their GLP-1 prescription medication for faster results, it may not be the best idea. Commercially available GLP-1 patches lack clinical evidence for safety and efficacy and might lead to adverse reactions.
Why are they so much cheaper than prescriptions?
Though most weight loss patches are marketed as GLP-1 patches, they do not contain a GLP-1 agonist, such as semaglutide or tirzepatide. Instead, these patches are a combination of different vitamins and compounds that may support weight loss, making them cheaper than prescription weight loss drugs.
Where can I buy them?
You can buy commercial weight loss patches on numerous websites, including Amazon and social media shops.
Will the patch stay on during showers or exercise?
You can exercise or shower with the patch as usual, but keeping the patch underwater for a long time can cause it to loosen or fall off.
How often would I need to change the patch?
The duration of keeping the patch depends on the medication you are taking. Patches for some medications, such as fentanyl, are recommended to be kept for 72 hours. Commercially available “GLP-1 support patches” are typically applied for 8 hours.
Where on the body would it be applied?
The patch must be applied to a clean area, as specified by your doctor or patient information leaflet. Sometimes, the manufacturer might suggest applying the patch to the arm, chest, or upper back, and others might recommend administration in the abdominal region.
What about skin irritation or allergic reactions?
Skin redness, itching, mild irritation, and contact dermatitis are common side effects of using a transdermal patch. Patients allergic to any of the active ingredients or manufacturing material in the patch may experience allergic reactions.
Could the patch fall off accidentally?
Yes, the patch may fall off accidentally if the skin is not clean and dry. The presence of hair, oil, lotion, etc., can affect the application of the patch. If the patch seems to loosen, apply medical tape to the sides to secure it properly. In case it falls off, clean the area thoroughly and apply a new patch after cleaning the area properly.
How will dosing be adjusted?
There are no clinical studies on the efficacy, safety, or dosing of GLP-1 patches, but they will likely follow the ‘titrating’ dosing method, similar to GLP-1 injections.
Will patches be available for both diabetes and weight loss?
GLP-1 drugs have been approved by the FDA for diabetes and weight loss, making way for GLP-1 patches for both indications. Pharmaceutical companies are researching the formulation of different transdermal patches for weight loss and diabetes, using efficient delivery technologies.
What happens if I forget to change my patch?
Leaving the patch on your skin can lead to irritation and contact dermatitis. You could also experience a drop in drug levels, which may reduce the effectiveness of the patch.
Can I cut the patch for dose adjustments? (Important safety warning)
Do not try to adjust the dosing yourself. Patches manufactured by pharmaceutical companies follow strict compliance rules and are approved for use when they meet the criteria. Cutting the patch can disrupt the delivery mechanism and may cause overdosing.
How should used patches be disposed of?
It is suggested to use gloves when removing someone else’s patch. Once you remove the patch, fold it in half in a way that the adhesive side is stuck together. Dispose of the patch in a childproof container or sharps disposal container. Make sure to wash your hands thoroughly after disposing of the GLP-1 patch.
Conclusion: Are GLP-1 patches right for me?
The sudden emergence of positive anecdotal reviews raving about GLP-1 patches is an excellent example of why you should not trust everything you see on social media.
GLP-1 medications, such as Wegovy, Ozempic, Mounjaro, and Zepbound, are approved by the FDA for their specific indications after rigorous testing and clinical trials. Studies have shown an average weight loss of 15% among patients taking GLP-1s, such as semaglutide.
The “GLP-1 patches,” on the other hand, do not contain any GLP-1 drug. They are a combination of natural compounds that may (not proven) promote weight loss. The FDA has not approved any GLP-1 weight loss patches yet because of the skin-penetration challenge.
GLP-1 drugs contain peptide molecules that cannot pass the skin barrier through the current transdermal patch technology. Delivery systems using microneedling technologies are being developed and tested to make GLP-1 patches a reality in the near future for people with needle anxiety. Until the FDA approves GLP-1 patches, it is best to stick with FDA-approved injectable and oral weight loss medications.
