What is Opill®?
Daily birth control pills your way.
Opill® is a progestin-only birth control pill (also known as a POP or mini pill.6) It contains only one hormone, progestin (norgestrel). Each tablet of Opill® contains 0.075 mg of norgestrel. Is Opill® the same as other hormonal birth control pills? No. Many other birth control pills contain both estrogen and progestin. Unlike combination birth control pills, Opill® is estrogen-free. As the first FDA-approved over-the-counter (OTC) daily birth control pill, Opill® is also more accessible than many other birth control pill alternatives.
How does Opill® work?
Rx Strength — Without the Rx.6
Opill® works in multiple ways. It causes cervical mucus to thicken and prevents your ovaries from releasing an egg in some cycles. Opill® works by6:
Increasing cervical mucus viscosity
: Thickens the cervical mucus, which helps block sperm from reaching the egg.
Suppressing ovulation in some cycles
: May also prevent ovaries from releasing eggs in some cycles.
What to expect when taking Opill®
Contraception can be complicated. Let’s break it down.
It starts working 48 hours, AKA 2 days*, after you take your first pill.6 Be sure to use a barrier method like condoms for the first two days to prevent pregnancy.
Progestin-only pills like Opill® have a well-established safety profile supported by decades of real-world experience2 Side effects vary by individual. The most-frequently reported side effect is irregular bleeding.8 That said, in a survey of people who used Opill® during a US clinical trial, 58% said the bleeding was similar to or better than their previous hormonal contraceptive method.3
Other potential side effects include:
Headaches
Dizziness
Nausea
Increased appetite
Abdominal pain
