Some people might experience stomach pain after taking ellaOne®. This is normally quite mild and should ease off, however if the pain becomes intense, or it concerns you, you should seek medical advice immediately.

Pharmacist Deborah Evans** advises that, “if you vomit within three hours of taking the morning after pill, consult your pharmacist or sexual health clinic as you may need to take another dose for the emergency contraception to be effective.”

She adds that, “if you are concerned at all about side effects and this is putting you off taking the MAP, then please do talk to your pharmacist or other healthcare professional who can listen to your concerns and advise you.”
