I-pill (Levonorgestrel) — Uses, Dosage, Side Effects & Safety

Drug class: Emergency contraceptive (Progestin-only)

Overview

I-pill is an emergency contraceptive tablet used to prevent pregnancy after unprotected sex or contraceptive failure, such as a broken condom. It contains levonorgestrel, a synthetic progestin hormone that works primarily by preventing or delaying ovulation, and may also prevent fertilization or implantation if ovulation has already occurred. I-pill is most effective when taken as soon as possible after unprotected intercourse, ideally within 12 hours, but it can be used up to 72 hours (3 days) after. It is not intended for regular contraception and does not protect against sexually transmitted infections (STIs). Key points: I-pill is a single-dose emergency contraceptive, should not be used as a routine birth control method, and is not effective if you are already pregnant. It is available over-the-counter in many countries.
