EllaOne serves as an effective form of emergency contraception, often referred to as the 'morning-after pill'. It is designed to prevent pregnancy after unprotected sexual intercourse or contraceptive failure, such as a broken condom. This medication contains the active ingredient ulipristal acetate, which works by delaying ovulation, thereby reducing the chance of fertilisation. EllaOne can be taken up to 120 hours, or five days, after unprotected sex, but it is most effective when taken as soon as possible. Widely available across the UK, ellaOne can be obtained over the counter without a prescription, enhancing accessibility for those who need it. However, as with all medicines, it's important to understand how to use ellaOne correctly, its potential side effects, and any precautions before taking it.
