Internal Medicine

Opill is a progestin-only birth control pill, also known as the "mini-pill." It contains norgestrel and is the first daily oral contraceptive available over-the-counter in the United States without a prescription. Unlike combination pills, Opill does not contain estrogen, making it a suitable option for many people who cannot take estrogen-based contraceptives.

If you're considering Opill or experiencing symptoms that may affect your reproductive or hormonal health, it's important to understand your body first. Every person responds to hormonal contraception differently, and side effects, underlying conditions, or interactions can influence whether Opill is right for you. Taking a free, instant, online symptom check can help you clarify what you're experiencing, identify possible causes, and guide your next steps—before you make a decision or speak with a provider.

Explanation

Opill is a type of birth control pill that contains only progestin, which is a hormone used to prevent pregnancy. Unlike some other birth control pills, it doesn't contain estrogen.

Key Points:

Progestin-Only: This means it only has one hormone, progestin, which works by thickening the mucus in the cervix to stop sperm from reaching an egg and by thinning the lining of the uterus.
Over-the-Counter: Opill is available without a prescription, making it easier for people to access.

Opill is a convenient option for those who prefer or need to avoid estrogen.
