What is Mercilon?

Mercilon is a combined contraceptive pill which contains two synthetic hormones, a Progestogen (Desogestrel) and Oestrogen (Ethinylestradiol). The reversible contraception doesn’t interrupt sex and can make periods lighter, more regular and less painful.

Mercilon prevents ovulation - the release of an egg from the ovaries - and thickens the mucous lining of the cervix, making it uninhabitable for sperm. These hormones also affect the lining of the womb to make it less likely that an egg will be able to implant itself.

When used correctly, Mercilon is 99% effective at preventing an unwanted pregnancy.

Please be aware that Mercilon does not protect you against sexually transmitted diseases. Only condoms are effective at preventing the spread of STDs.

How do I take Mercilon?

You should take Mercilon for 21 days out of every 28. On the 7 days you do not take Mercilon your period will occur.

If you miss a dose, or are taking antibiotics, you should use additional protection, such as condoms, for 7 days.

Oral contraceptives only provide protection if taken regularly.
