Pharmacy-only (P) medicine — a short WHAM screening is required before purchase.
Product Overview
Emergency contraception tablet (ulipristal acetate 30mg) for use within 120 hours (5 days) after unprotected sex or contraceptive failure. Take 1 tablet as soon as possible.
Description
ellaOne 30mg tablet is an emergency contraceptive intended to help prevent pregnancy after unprotected sex or contraceptive failure (for example, condom breakage/slippage or missed contraceptive pill).
- Take as soon as possible after unprotected sex, and no later than 120 hours (5 days). It is more effective the sooner it is taken.
- Works by postponing ovulation (it does not work if you are already pregnant and will not interrupt an existing pregnancy).
- Not for regular contraception. If you do not have a regular method, ask a pharmacist/GP/sexual health clinic about suitable ongoing options.
- Does not protect against sexually transmitted infections (STIs). Condoms help protect against STIs.
Pack contents: 1 film-coated tablet in a blister pack.
Legal category: Pharmacy medicine (P) in UK dm+d listing.
How to Use
Always take this medicine exactly as described in the leaflet or as advised by a pharmacist/doctor.
- Dose: Take one tablet by mouth as soon as possible and no later than 5 days (120 hours) after unprotected sex or contraceptive failure.
- Can be taken at any time in your menstrual cycle, and before, during or after food.
- If you vomit within 3 hours of taking the tablet, take another tablet as soon as possible.
After taking ellaOne:
- Use condoms every time you have sex until your next period, because unprotected sex after taking it can still lead to pregnancy.

- Your next period may be a few days late. If it is more than 7 days late, unusually light/heavy, or you have pregnancy symptoms, do a pregnancy test and seek advice.
