Mercilon is a combined oral contraceptive (the pill), which can be taken daily to prevent pregnancy. If taken in the correct manner, Mercilon is proven to be almost 100% effective at preventing pregnancy . Mercilon is a variant of Marvelon that has a lower dosage of synthetic oestrogen, making it a better choice for women who are more sensitive to this hormone.
If you take it on the first day of your period, Mercilon's contraceptive effects will be immediate. If you take it later, it may take up to seven days to become effective. Like other variants of the pill, it can help to make painful periods less uncomfortable and more regulated. Pre-menstrual symptoms could also become less severe when you take the pill.
Weight gain is one of the main concerns women have when using oral contraceptives. Mercilon pills contain less oestrogen than most traditional combination contraceptives; this significantly reduces your chances of gaining weight while on the pill. Some research has even shown that using this contraceptive can possibly cause a slight reduction in weight with long-term use.
Mercilon tablets will not protect you or your partner against any sexually transmitted diseases/infections. If you've had unprotected sex and are worried you might have contracted an STI, you should talk to your doctor right away, or visit a walk-in sexual health clinic.
Alternatively, you can take a look at some of the STI treatment options available from HealthExpress.
Starting your first Mercilon pill on the very first day of your period offer immediate protection. You can find out more details about using this combined contraceptive in the attached patient information leaflet or by consulting with your doctor.
If you happen to forget to take your pill or more than one pill in one blister pack at the usual time, you can follow the below protocol:

*Vomiting and diarrhoea experienced within four hours of taking the pill is also classed as a missed pill.
*There are more than seven pills left in the pack. Continue to finish the pack, overlapping the seven-day break. Take your seven-day break and start your new pack as usual.
*There are fewer than seven pills left in the pack. Continue to finish the pack, overlapping the seven-day break. Start the new pack immediately after the old one is finished (missing out the seven-day break completely).
*If you have missed contraceptive pills in the first one to nine days of the pill pack and have had sex without barrier contraception, you could be pregnant. If you have calculated this between one to five days after the unprotected sex, you could use emergency contraception such as the IUD or morning-after pill. If not, continue your contraception until the seven-day break. If you don't have any bleeding, it is advised to take a pregnancy test and/or consult your doctor.
For more information about what to do if you've missed your dosage for a significant period, it's always best to speak to your doctor or pharmacist.
There is a single standard dosage for Mercilon tablets. Each pill contains 150mcg of the progestogen desogestrel and 20mcg of the oestrogen ethinyl estradiol. This quantity has been formulated to be effective whilst also minimising potential undesirable reactions.
Side effects are very rare with this medication, but if they do occur, they are usually mild and will pass as soon as your body has adjusted to the hormones. Possible side effects of the Mercilon pill include:
Some pills have high oestrogen content, and oestrogen affects body mass. However, since Mercilon contains less of this hormone than some other contraceptives, weight gain is reported less by women using this particular treatment.
Women using Mercilon pills for the first time may experience side effects such as spotting, breakthrough bleeding or missed periods. You should talk to your GP if any breakthrough bleeding continues, though.
