Birth Control and the NuvaRing

What Is the NuvaRing?

The NuvaRing is a birth control option for women. It is a small flexible contraceptive ring, about the size of a silver dollar.

How Does the NuvaRing Work?

The 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 the NuvaRing?

When used correctly, the NuvaRing is 98%-99% effective in preventing pregnancy.

Are There Side Effects Associated With NuvaRing?

Women who have migraines should consult their doctor.

No. The NuvaRing does not protect against sexually transmitted diseases (STDs), including HIV (the virus that causes AIDS). The male condom provides the best protection from most STDs.
