3. How to take MERCILON
When and how to take the tablets
The MERCILON pack contains 28 white tablets: 21 large tablets with the active substances and 7 small tablets without active substances. On the pack, each tablet is marked with the day of the week on which it is to be taken. One tablet is to be taken daily for 28 consecutive days. Take your tablet at about the same time each day, with some liquid if necessary. The first tablet should be taken from the blister in the green section of the calendar pack marked with the appropriate day of the week. Follow the direction of the arrows until all 28 tablets have been taken. A period should begin during the 7 days that you use the placebo tablets (the withdrawal bleed). Usually, it will start on day 2 to 3 after the last large tablet. Start taking your next pack immediately after the last placebo tablet, even if your period continues. This means that you will always start new packs on the same day of the week, and also that you have your withdrawal bleed on about the same days, each month.
Starting your first pack of MERCILON
When no hormonal contraceptive has been used in the past month
Start taking MERCILON on the first day of your cycle i.e., the first day of menstrual bleeding. Take a tablet marked with that day of the week, starting in the green section of the calendar pack. For example, if your period starts on a Friday, take the tablet marked Friday in the green section of the calendar pack. Then follow the days in order in the direction of the arrows. MERCILON will work immediately. You do not need to use an additional contraceptive method. You may also start on days 2 to 5 of your cycle, but in that case make sure you also use an additional contraceptive method (barrier method) for the first 7 days of tablet-taking in the first cycle.
