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.
How do Mercilon pills work?
Mercilon pills work in three ways:
Firstly, the two active ingredients found in Mercilon prevent ovulation from occurring, so that the ovaries don't release an egg that could potentially be reached by a sperm.
Secondly, to prevent sperm from entering the womb, Mercilon pills increase the viscosity of the mucous in the womb.
As a third and final measure, this treatment ensures that the womb lining doesn't thicken up enough for an egg to grow and develop.

What are the benefits of Mercilon?
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.
Does the Mercilon combined pill protect me against STIs?
Mercilon tablets will not protect you or your partner against any sexually transmitted diseases/infections. If you've had 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.
How do I take the Mercilon pill?
Starting your first Mercilon pill on the very first day of your period offer immediate protection. If you start on any other day, you will need to use an additional barrier contraceptive such as condoms for the following seven days before the pill is 99% effective. You can find out more details about using this combined contraceptive in the attached patient information leaflet or by consulting with your doctor.
Mercilon pills are taken for 21 continual days.
They should be taken at around the same time every day to be fully effective.
This is followed by a seven-day rest period.
You may experience withdrawal bleeding similar to that of your regular period during this time.
You will still be protected during the pill-free week.
If not taken on the first day of your period, use condoms for the following seven days.Take each pill around the same time every day for maximum effectiveness of over 99%. Many women set an alarm to remember their next dose.Each Mercilon pill can be easily swallowed with or without drink and food.Store away from direct sunlight and under the temperature of 25°C.Double check the expiry date and patient leaflet regarding use and missed pill if unsure.
What should I do about a missed Mercilon pill?
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:
If you have missed one Mercilon pill, then take it as soon as possible unless it is close to the time of your next pill. If it is nearer to the next pill than the previous time, miss it out completely and continue with the blister pack as normal. Missing one pill in one blister pack will not affect the effectiveness of a combined pill. You will not need further barrier protection.
If you miss two or more pills in one blister pack, then you will not be protected at the level of 99%. Take the last missed pill as soon as you remember unless it is close to the time of your next pill. Taking two pills in close proximity will not combat the mistake - and skip the previous missed pills. Use condoms for the next seven days or refrain from sex.
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.

*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.
What dosages are available for Mercilon?
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.
Are there any side effects when taking Mercilon?
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:
Does Mercilon cause weight gain?
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.
Mercilon and breakthrough bleeding
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.
