Annovera is a flexible vaginal ring used to prevent pregnancy. It is inserted for 21 days of each cycle and contains two hormones which are slowly released over time.
Annovera is a birth control medication used to prevent pregnancy. It is a single product containing 2 kinds of female hormones: segesterone acetate, a progestin, and ethnyl estradiol, an estrogen. Annovera works by preventing ovulation (the release of an egg from the ovaries). It also changes the lining of the uterus (womb) to prevent pregnancy from developing and changes the mucus at the cervix (opening of the uterus) to prevent sperm from entering.
This medication comes as a flexible vaginal ring and is inserted and left in place for 3 weeks. After three weeks, it is removed for a 1-week break, then the same ring is reinserted for up to 1 full year (1 year includes 13 cycles; each cycle is 28 days).
Common side effects of Annovera include headache, nausea/vomiting, and vaginal yeast infection.

This is not a complete list of Annovera drug interactions. Ask your doctor or pharmacist for more information.
Serious side effects have been reported with Annovera including the following:
- blood clots. Like pregnancy, hormonal contraceptives increase the risk of serious blood clots, especially in women who have other risk factors, such as smoking, obesity, or age greater than 35. This increased risk is highest when you first start taking hormonal contraceptives and when you restart the same or different hormonal contraceptive after not using it for 4 weeks or more.
It is possible to die or be permanently disabled from a problem caused by a blood clot, such as a heart attack or a stroke. Some examples of serious blood clots are blood clots in the:
- legs (deep vein thrombosis)
- lungs (pulmonary embolus)
- eyes (loss of eyesight)
- heart (heart attack)
- brain (stroke)
Call your healthcare provider or get emergency medical care right away if you have:
- leg pain that does not go away
- sudden shortness of breath
- sudden changes in vision or blindness
- severe pain or pressure in your chest
- a sudden, severe headache unlike your usual headaches
- weakness or numbness in an arm or leg
- trouble speaking
- toxic shock syndrome (TSS). Some symptoms of TSS are the same as flu symptoms, but they can become serious very quickly. Call your healthcare provider or get emergency medical care right away if you have the following symptoms:
- sudden high fever
- fainting or feeling faint when standing up
- a sunburn-like rash
- muscle aches
- liver problems, including liver tumors. Tell your healthcare provider right away if you have yellowing of your skin or eyes (jaundice)
- high blood pressure.
- gallbladder problems or worsening of a gallbladder problem you already have. You may have an increased risk of gallbladder problems with the use of Annovera if you had gallbladder problems when you were pregnant.
- changes in the sugar and fat (cholesterol and triglycerides) levels in your blood.
- headache. Tell your healthcare provider if you have new headaches that keep coming back, that do not go away, or are severe. Also tell your healthcare provider if your migraine headaches happen more often or are more severe than normal.
- irregular or unusual vaginal bleeding and spotting between your menstrual periods, especially during the first month of using Annovera, or the absence of menstrual periods (amenorrhea).
- possible cancer in your cervix.
- swelling of your skin especially around your mouth, eyes, and in your throat (angioedema). Call your healthcare provider or get emergency medical care right away if you have a swollen face, lips, mouth, tongue, or throat as this may lead to difficulty swallowing or breathing. Your risk of having angioedema is higher if you have a history of angioedema.
- dark patches of skin on your forehead, cheeks, upper lip, and chin (chloasma). Your risk of getting chloasma with the use of Annovera is higher if you had chloasma during pregnancy. Women who tend to get chloasma should avoid spending a long time in sunlight, tanning booths, and under sunlamps while using Annovera. Use sunscreen if you have to be in the sunlight.
Do not use Annovera if you smoke cigarettes and are over 35 years old. Smoking increases your risk of serious heart and blood vessel (cardiovascular) side effects from hormonal birth control methods, including death from heart attack, blood clots, or stroke. This risk increases with age and the number of cigarettes you smoke.

- smoke and are over 35 years old. See above.

- have a problem with your blood that makes it clot more than normal.
- have high blood pressure that is not controlled with medicine or have high blood pressure with blood vessel damage.
- have diabetes and are over 35 years old; have diabetes with high blood pressure or problems with your kidneys, blood vessels, eyes, or nerves; or have had diabetes for longer than 20 years.
