Short facts about Mercilon
How to take

Mercilon is taken over 21 days of the month. This is one tablet daily, at the same time, with a seven day break where you will experience a withdrawal bleed similar to a period.

How it works

Mercilon works by not producing an egg the vast majority of the time, thickening the cervical fluid so the sperm cannot penetrate and altering the womb lining so an egg can't attach itself.


Mercilon is 99% effective at preventing pregnancy as well as easing painful menstrual cramps and other period related symptoms.


There is one dosage available to buy online in the UK. This contains 150mcg of ethinyl estradiol and 20mcg of desogestrel.

Side effects

Side effects, especially those that can cause distress, are rare with Mercilon. If you do experience side effects, these tend to pass over a couple of months or are extremely manageable, and include breast tenderness, nausea/vomiting and spotting.
