Implant

What is it? How does it work?
The implant is a small rod that is placed just beneath the skin in your upper arm. It protects you from pregnancy for about three to four years. The implant works by releasing progestin, which is a hormone that prevents your ovaries from releasing eggs each month and thickens your cervical mucus.

How effective is it?
The implant is greater than 99% effective, even with typical use. Like the IUD, the implant can be removed at any time.

What are the side effects?
The most common side effects people complain about are irregular bleeding and unpredictable periods.

Does it protect me against sexually transmitted infections?
The implant does not provide protection against sexually transmitted infections (STIs).
