Minipiller

Minipiller, formally the progestin-only pill (POP), is a type of oral contraceptive that contains no estrogen. It uses a small daily dose of a synthetic progestin to prevent pregnancy and is available in various formulations under different brand names.

How it works varies by individual, but the main effect is to thickening of cervical mucus, which makes it harder for sperm to reach the egg. It also thins the lining of the uterus and, in some users, may suppress ovulation. Because it does not rely on estrogen, it is often chosen by people who cannot take estrogen-containing contraceptives or who are breastfeeding.

Usage and timing are important. The minipill is taken orally once daily, at roughly the same time each day. Most brands require a short, specific time window for dosing (often a few hours); missing doses or taking them late can increase the chance of pregnancy.

Effectiveness varies with typical use and perfect use. Typical-use effectiveness is about 91%, with perfect use around 99%. The effectiveness of the minipill can be reduced if a dose is delayed, and it does not protect against sexually transmitted infections.

Advantages include suitability for breastfeeding, fewer estrogen-related side effects, and a generally favorable safety profile for people with high blood pressure or clotting risk. Common side effects are irregular vaginal bleeding, especially in the first months, headaches, breast tenderness, and mood changes. It is contraindicated in pregnancy and certain medical conditions; always consult a healthcare provider for individual guidance.
