What is ellaOne?

ellaOne is an emergency hormonal contraceptive pill that acts by modifying the activity of the natural hormone progesterone. It is thought to work by stopping your ovaries from releasing an egg, although is not effective in every case. Clinical studies showed that when used between 0 and 72 hours after unprotected sex or contraceptive failure, ellaOne was equally as effective as Levonelle. The observed pregnancy rate was 1.5% in both studies. In another clinical trial in women who presented for emergency contraception between 48 and 120 hours after unprotected sex or contraceptive failure, the observed pregnancy rate was 2.1%.

After using ellaOne it is recommended to use a condom until your next period starts as it can interfere with the normal contraceptive pill. Pharmacy2U Online Doctor Service offer a convenient and confidential Morning after pill consultation service that can lead to ellaOne being prescribed.

How to Use ellaOne?

A tablet should be taken as soon as possible, and no later than 120 hours after unprotected intercourse. It is more effective, the earlier it is taken. If vomiting occurs within three hours of taking the tablet, you should take another tablet. ellaOne can be used at any time during the menstrual cycle unless menstrual bleeding is overdue as you should NOT take the drug if you might be pregnant.

If you become pregnant after taking ellaOne it is important that you consult with your doctor at the earliest opportunity.

Do not use it if you are breast feeding.

Repeated use within the same menstrual cycle is not advisable and it is not as effective as the normal contraceptive pill so should in no instance replace a regular contraceptive method. The patient information leaflet should be read carefully before use.
