Nuvaring side effects

NuvaRing side effects and how to avoid them

Choosing a birth control method can be a difficult decision as there are so many options. Hormonal contraceptives are commonly used and one option is NuvaRing, a flexible birth control vaginal ring used to prevent pregnancy. Oral birth control pills are absorbed through the digestive tract however with NuvaRing the hormones are released directly into the bloodstream. Like other hormonal birth control methods, NuvaRing also increases the risk of serious blood clots, especially in women who have other risk factors, such as smoking. Let’s take a look at the adverse reactions associated with the NuvaRing and how to avoid them.

What is NuvaRing?

NuvaRing is a prescription birth control vaginal ring used to prevent pregnancy. It is a soft and flexible ring that is slightly larger than a 50-cent piece. You use it by inserting it into your vagina (following the patient information instructions that come with your NuvaRing ). Once inside you, NuvaRing releases two substances into your body that are man-made versions of the natural hormones estrogen and progestin, that stop you from getting pregnant.

How to use NuvaRing

NuvaRing is used in a 4-week cycle. You wear a NuvaRing for three weeks at a time, then you take it out for one week before you insert a new ring. During the one week that you do not wear a NuvaRing, you usually have your period. If used properly, NuvaRing is just as effective as the contraceptive pill, but you do not need to take it every day. The NuvaRing is simple to insert, similar to a tampon.

NuvaRing active ingredients

NuvaRing contains two active ingredients called ethinylestradiol and etonogestrel. Ethinylestradiol is a synthetic (man-made) version of the hormone estrogen that your body naturally produces. Etonogestrel is a synthetic version of the hormone progesterone produced naturally by your body.

Estrogen and progesterone are hormones that play a role in the female reproductive cycle. The ethinylestradiol and etonogestrel in NuvaRing have the same effects on your body as these natural hormones. They stop your ovaries from releasing an egg each month (ovulation). They can also change the lining of your womb (uterus), stopping a fertilized egg from attaching to it and developing. Finally, they can change the mucus created by your cervix (the opening of your womb), which can prevent sperm from entering your womb.

Dosing of NuvaRing

When placed in the vagina, each ring releases on average 0.120 mg/day of etonogestrel and 0.015 mg/day of ethinyl estradiol over a three-week period of use.

NuvaRing has an outer diameter of 54 mm and a cross-sectional diameter of 4 mm. It is made of ethylene-vinyl acetate copolymers and magnesium stearate and contains 11.7 mg etonogestrel and 2.7 mg ethinyl estradiol. NuvaRing is not made with natural rubber latex.

How to avoid NuvaRing side effects

1. Read the patient information for NuvaRing use

When used as directed by your healthcare professional NuvaRing has been shown to be very effective. Your chance of getting pregnant depends on how well you follow the directions for using NuvaRing. The better you follow the directions, the less chance you have of getting pregnant.

Follow the instructions on how to insert a NuvaRing thoroughly and seek help from your doctor if you are unsure. The patient leaflet will show you a step-by-step guide on the correct way to insert NuvaRing. It is possible to accidentally insert the NuvaRing into your bladder. If you have pain during or after insertion and you cannot find NuvaRing in your vagina, call your health care provider right away.

2. Discuss medical history

Discussing your medical history with your healthcare provider is important to help them understand how well NuvaRing will work for you. Give a complete list of all the prescription drugs, including over-the-counter meds, supplements, medical conditions you may have, and if you smoke. Talking with your doctor will allow them to pick up any drug interactions with NuvaRing and help manage any possible side effects.

3. Pay attention to your body

Paying attention to how your body feels when taking NuvaRing is important. As mentioned earlier in the blog, blood clots and TSS are a risk with NuvaRing. If you experience any of the symptoms associated with these serious side effects seek medical help urgently.

Due to NuvaRing entering your bloodstream directly it can bring on a more powerful reaction. It is important that you learn which symptoms are dangerous so you can treat them quickly with medical advice and attention.

Talk to your doctor straight away if you start to experience any side effects of NuvaRing when taking it, or if you feel the medication is not working for you.

5. Store NuvaRing correctly

Store NuvaRing at room temperature for up to 4 months after you receive it. Throw NuvaRing away if the expiration date on the label has passed. Do not store NuvaRing above 86°F (30°C) and avoid direct sunlight. To dispose of NuvaRing place the used NuvaRing in the re-closable foil pouch and throw it away in your household trash. Do not flush your used NuvaRing down the toilet.
