What is NuvaRing?
NuvaRing is a new birth control option for women. It is a small flexible contraceptive ring, about the size of a silver dollar.
How Does It Work?
NuvaRing contains the same hormones as many birth control pills. It is inserted manually into the vagina, where it is left for three weeks. There, a continuous, low dose of hormones is released.
Then the ring is removed for one week. This is the week you'll have your period.
How Effective Is NuvaRing?
When used correctly, NuvaRing is 98%-99% effective in preventing pregnancy.
Are There Side Effects Associated With NuvaRing?
The most common side effects reported by users are:
- Headache
- Weight gain
- Nausea
- Breast tenderness
Who Should Not Use NuvaRing?
Some women should not consider the NuvaRing. They include women:
- With a history of blood clots, heart attack or stroke
- With breast cancer
- Who are pregnant or think they might be
- Over 35 who smoke cigarettes
Does NuvaRing Protect Against Sexually Transmitted Diseases?
No. NuvaRing does not protect against STDs, including HIV (the virus that causes AIDS). The male condom provides the best protection from most STDs.
