What Is the NuvaRing?

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

How Does It Work?

The NuvaRing contains the same hormones as many birth control pills. A woman inserts it into her vagina, where it stays for 3 weeks, releasing a steady, low dose of hormones.

The woman removes the ring for 1 week when she'll have her period.

How Effective Is the NuvaRing?

The NuvaRing prevents almost all pregnancies when it's used correctly. It’s 98%-99% effective, which means only 1-2 women out of 100 who use it would accidentally get pregnant.

Are There Side Effects?
