Januvia alternatives

Januvia alternatives: which other diabetes medications can I take?

Januvia is a brand name diabetes drug manufactured by Merck Pharmaceuticals. It is one of many diabetes medicines used to control blood glucose levels in people with type 2 diabetes mellitus.

The number of medications available to treat type 2 diabetes in particular, is long and confusing at first. No single diabetes treatment is best for everyone and what works for one person may not work for another. Always seek medical advice when considering changing medication.

Let us take a look at the alternative diabetes medications available to Januvia, simplify how they work, and what common side effects they may have. This knowledge will allow you to discuss the different treatment options with your doctor.

What is Januvia?

Januvia is a prescription medicine approved by the U.S Food and Drug Administration to:

  • Treat type 2 diabetes, by helping to lower blood sugar levels when used in combination with exercise and changes to your diet

In type 2 diabetes you do produce insulin, but the body can not use it effectively. There is usually a combination of a part failure of insulin production and a reduced response to the hormone. This is known as insulin resistance. Research does not give us a clear idea why some people develop this and others don’t, but lifestyle factors, e.g. lack of exercise and excess body weight can contribute to type 2 diabetes. Januvia is not recommended to be used to treat type 1 diabetes.

Januvia active ingredients

The active ingredient in Januvia is called sitagliptin. It works by increasing the amount of insulin you produce after you’ve eaten.

When you digest food, your stomach and gut produce digestive hormones called GLP-1 and GIP. These hormones make your pancreas secrete insulin. As you continue to digest your food, the digestive hormones are broken down by an enzyme called dipeptidyl peptidase-4 (DPP-4) to allow your levels of insulin to fall again.

Sitagliptin stops the DPP-4 enzyme from breaking down the digestive hormones. This keeps the hormones active for longer, making you produce more insulin, and lowering your blood sugar to normal levels.

Side effects of Januvia

The most common side effects of Januvia include:

  • Headaches
  • Stuffy or runny nose
  • Sore throat
  • An increase in upper respiratory tract infections, like colds, sinus infections, and the flu
  • Constipation

Often these side effects disappear after a few weeks of use. Occasionally, Januvia can cause more serious side effects. These include:

  • Severe joint pain
  • Heart failure
  • Inflammation of the pancreas (pancreatitis) can be fatal in severe cases
  • Serious allergic reactions to the medication can cause anaphylaxis – a potentially life-threatening condition where your immune system overreacts, causing hives, swelling in your face, mouth, and throat that causes shortness of breath and trouble breathing
  • Kidney problems that can reduce kidney function or require dialysis
  • Dangerously low blood sugar levels (hypoglycemia)

Your doctor will assess your risk of side effects versus the benefits of taking Januvia.

If you take Januvia you could experience side effects, including the most serious, but everyone reacts differently to medication. If you have any concerns about side effects, talk to your physician or a pharmacist. You may report side effects to the FDA at 1-800-FDA-1088 or at www.fda.gov/medwatch.

Other diabetes medications

Diabetes is much more than just blood glucose levels e.g. type 2 diabetics have a higher risk of heart attacks and strokes, therefore medications to control blood pressure and cholesterol are very useful.

Here are some of the most widely used medications:

  • ACE inhibitors – act on your kidneys to treat high blood pressure
  • AIIRA’s – reduces high blood pressure
  • Aspirin – reduces the stickiness of your blood, making you less prone to heart attacks and stroke
  • Statins – they lower your LDL cholesterol (considered the bad cholesterol) and raise your HDL (considered good cholesterol) helping to protect you against heart disease

As a diabetes patient, it is essential to discuss your medical history with your healthcare provider to avoid complications and to help them understand how well your medication will work for you. Give a complete list of all the prescription medications, including over-the-counter meds, supplements, and medical conditions you may have. Talking with your doctor will allow them to pick up any drug interactions and help manage any possible side effects.
