Opill® is your powerful ally in birth control. It’s a full prescription strength, progestin-only daily birth control pill that’s estrogen-free. Unlike combined pills, Opill® uses only one hormone, progestin, to prevent pregnancy, making it suitable for most individuals. (If you currently have or have previously had breast cancer, you should not take Opill®. Use as directed.) So, whether you are breastfeeding, a smoker or have hypertension, Opill® is here to support you. Opill is the most effective over the counter birth control method for women and people who can become pregnant. When used as directed, Opill® is 98% effective at preventing unplanned pregnancies. The best part? You don't need a doctor's appointment or a prescription before you begin using it. No hassle, no worries. *These statements have not been evaluated by the Food and Drug Administration.
