Birth Control Options Compared (2026): Effectiveness and How to Get Each
There is no single best birth control —only what fits your body and life. Here is a clear comparison by effectiveness, plus where to get each method.
Most effective: long-acting methods
- IUD (hormonal or copper): more than 99% effective, lasts years, reversible. The copper IUD is also the most effective emergency contraception if placed within 5 days.
- Implant (a small rod in the arm): more than 99% effective, lasts several years.
Very effective: hormonal methods you use regularly
- The shot (every ~3 months), pill, patch, and ring: very effective with correct use; effectiveness drops if doses are missed or late.
- Opill, a daily progestin-only pill, is now available over the counter without a prescription.
Effective with consistent use
- Condoms: the only method that also reduces the risk of sexually transmitted infections. Available over the counter.
Emergency contraception
- Plan B and similar (levonorgestrel): available over the counter; most effective the sooner it is taken.
- ella (ulipristal acetate): prescription; effective a bit later than levonorgestrel.
- Copper IUD: the most effective emergency option if placed within 5 days.
Where to get birth control
Health centers, Planned Parenthood, your doctor, and —for OTC methods like condoms, Opill, and Plan B— pharmacies and many stores. Many clinics offer it free or low-cost.
