Mercilon

What is this Mercilon used for​​​?

Mercilon® is a combined hormonal contraceptive that contains two types of female hormones, estrogen and progestogen. This medication can help prevent ovulation and regulates other naturally occurring hormones in the body. When taken correctly, this prevents pregnancy and promotes regular menstrual bleeding. 

Dosage and How to Use​

• Do not stop taking your medication without checking with your healthcare professional.
• If you are switching from other forms of contraception, please seek advice from your healthcare professional. 
• You should take this medication after food.
• You may start taking this medication on the first or second day of your menses (if this is your first time taking hormonal contraceptives or restarting this medication after a break).
• If you are also using it for contraceptive purposes, a barrier method of contraception (e.g. condoms), is recommended for the first 7 days of taking this medication for the first time.
• You should take one tablet daily for 21 days in a row, preferably at the same time every day.  After completion of the pack, there will be 7 days where you do not need to take any tablets (7-day tablet-free interval), during which you will experience withdrawal bleeding (menses) within two to three days after the last tablet. 
• Start taking your next pack of medication after the 7-day tablet-free days, even if you are still having menstrual bleeding. 

If you vomit or suffer from diarrhea within 3 to 4 hours of taking this medication, the tablet may not be absorbed. This is considered a missed dose. You should then follow the instructions above. 

What are the possible side effects of Mercilon?​

• Spotting or bleeding may occur between your periods during the first few months of taking oral contraceptives. However, if this continues after the third month, check with your doctor.

• Breast tenderness
• Headache or migraine - You may take painkillers such as Paracetamol to manage headaches
