NuvaRing, also called the vaginal ring, is a form of birth control for women that is 99 percent effective when used correctly. NuvaRing contains estrogen and progesterone, which prevents eggs from being released from the woman's ovaries, and causes changes in both the cervix and the lining of the uterus. As its name implies, NuvaRing is inserted into the woman's vagina the first Sunday after her period begins. Certain medications can interfere with the effectiveness of NuvaRing, such as the antibiotic rifampin, oral yeast infection medications, HIV medications, anti-seizures medications and St. John's Wort.
Ovarian Cysts
Use of NuvaRing does not cause cysts, according to Planned Parenthood; instead, NuvaRing reduces the risk of developing ovarian cysts. According to the Mayo Clinic, "ovarian cysts are fluid-filled sacs or pockets within or on the surface of an ovary." Ovarian cysts are harmless and should not be painful. However, the Mayo Clinic notes that serious symptoms can occur if the ovarian cyst ruptures.
HPV
HPV, or human papillomavirus, is a sexually transmitted disease; certain strains of HPV can cause cervical cancer or genital warts. Use of NuvaRing does not cause HPV; the virus can only be contracted through contact with an infected person. In addition, NuvaRing does not protect against sexually transmitted diseases. Neither Planned Parenthood nor the Women's Clinic and Family Counseling Center say that patients who have HPV are restricted from using NuvaRing. However, patients should talk to their doctor if they have any concerns.
Side Effects
While NuvaRing does not cause cysts or HPV, other side effects are possible. According to Planned Parenthood, women who used NuvaRing may experience bleeding in between their periods, breast tenderness, nausea and vomiting, increased vaginal discharge, vaginal irritation and infection. Side effects of NuvaRing are similar to oral contraceptives, since they contain the same hormones.
