What is Mercilon?

Mercilon is a prescription birth control treatment that is 99% effective in preventing pregnancy when used correctly. It can also regulate your periods and reduce premenstrual symptoms.

Mercilon is often prescribed as an alternative contraception treatment to Marvelon as it has a lower amount of oestrogen. Each pill contains 150mcg of desogestrel and 20mcg of ethinylestradiol.

What are the benefits of using Mercilon?

Mercilon provides immediate contraceptive protection when started on the first day of your period. It can also reduce the pain you experience during your period as well as premenstrual symptoms.

Mercilon is a popular alternative to Marvelon, as it contains a lower dose of synthetic oestrogen, making it more suitable for women who are sensitive to this hormone. This means that the risk of weight gain is also reduced.

How does Mercilon work?

The active ingredients in Mercilon work in three different ways:

  • they prevent ovulation so that eggs are not released for fertilisation
  • they prevent the womb lining from thickening enough for an egg to attach and grow
  • they prevent sperm from entering the womb by thickening the cervical fluid

How do I take Mercilon?

For immediate contraceptive protection, begin taking the tablets on the first day of your period. If you take it after that, you should use another form of contraception for the first seven days as it will take longer for it to be effective.

You should take one tablet at the same time each day for 21 days, followed by a 7 day break, during which you will still be protected. After that, begin the next strip.

Take care to read the patient information leaflet thoroughly before you buy Mercilon. You will find one included with your medication and a version you can download on this page.

What if I miss a pill?

If you are less than 12 hours late, you should take the next pill as soon as possible, even if it means taking two pills at the same time. Protection against pregnancy will not be reduced.

If you are over 12 hours late, the next steps depend on when you were supposed to take it. Refer to the patient information leaflet for further instruction.

If you have any stomach trouble, such as vomiting or diarrhoea, shortly after taking your pill, the hormones may not have had a chance to get into your system and your protection against pregnancy may be reduced. If you experience this you should follow the same instructions as a missed pill.

What precautions should I take?

You should not use Mercilon contraceptive pills if you:

The combined pill is not recommended if you smoke and are over the age of 35. Talk to your doctor about other contraception options.

You should always inform your doctor about any other medications or supplements you are currently taking, even if they are not prescribed, as there could be a possible interaction. This includes medications used to treat epilepsy, certain antibiotics, certain sedatives, St. John’s Wort, antifungal drugs, and laxatives.

Blood clots

Women who take combined contraceptive pills are at an increased risk of getting a blood clot compared with those who don’t. Your risk is further increased with smoking, increased age, certain heart conditions, diabetes, certain medications, if you’ve recently had a baby, if you are overweight, and if it’s your first year of taking them.

Signs include painful swelling in the leg, sudden chest pain, and difficulty breathing. You can read the patient information leaflet for more information on how to spot a blood clot. It’s important to seek immediate medical help if you think you have one.

Are there any side effects?

Birth control pills are usually well-tolerated, but all medications come with the risk of side effects. The most common include:

  • Migraine or headache
  • Breast tenderness
  • Mood changes
  • Nausea or vomiting
  • Breakthrough bleeding or spotting between periods

Some women report feelings of depression when on contraceptive pills. If you experience very serious mood changes or depressive symptoms, get in touch with your GP as soon as possible.

You may not experience any side effects or notice that your side effects disappear after a few days. For a full list, read the patient information leaflet. If you experience anything that you feel is more serious, contact a health professional as soon as possible.
