EllaOne is a 'morning after pill' that is taken in a single dose for emergency contraception. EllaOne is the newest form of 'morning after pill' available and be taken up to 120 hours (5 days) after unprotected sex or contraceptive accident and still remain effective. EllaOne is thought to be up to 98% effective at preventing pregnancy as long as it is taken within 120 hours of the incident.
EllaOne contains the hormone ulipristal acetate. It acts to prevent the release of eggs from the ovaries during ovulation and to reduce the chance of a fertilised egg implanting in the womb.
EllaOne should be taken as soon as possible after unprotected sex. A very small minority of women feel sick after taking EllaOne, if you are sick within 3 hours of taking the tablet you must obtain a further supply as you will not be covered.
EllaOne may cause your next period to come earlier or later than normal, and it may be heavier or lighter than usual.
You should continue using your regular method of contraception after taking EllaOne, emergency contraception will not protect you for the rest of your cycle.
