How does Mercilon work?

The Mercilon contraceptive pill contains synthetic forms of both oestrogen and progestogen. The presence of both of these hormones makes Mercilon the more effective option than progestogen only mini-pill alternatives for many women.

Mercilon is nearly 100% effective and works using a three-stage process for pregnancy prevention.

  • Step 1 - It tricks the body into thinking that ovulation has already occurred
  • Step 2 - It alters the lining of the womb preventing any fertilised egg from latching on to develop
  • Step 3 - It thickens the naturally occurring fluids in the cervix, which stops sperm from travelling into the womb


Mercilon also boasts a more finely balanced concentration of the active ingredients than some of its counterparts, making this combined contraceptive option more acceptable than others. In particular, the Mercilon pill can be viewed as an effective alternative for women who have experienced difficulties when using similar, but stronger, contraceptive pills like Marvelon.

What are the benefits of Mercilon?

The Mercilon pill offers immediate protection when taken on the first day of a woman's period, whilst the three-step process and combination of both oestrogen and progestogen make it one of the most effective contraception methods available.

Mercilon also contains a lower concentration of oestrogen, and so has a reduced risk of causing side effects like weight gain. In fact, some women have experienced weight loss after long-term use of this treatment. Mercilon can also have a positive effect on the symptoms of acne, with many women noting a visible improvement after using this medication.

Mercilon dosage and instructions

Mercilon contains two hormones

  • Ethinylestradiol (20mcg) - a synthetic form of oestrogen
  • Desogestrel (150mcg) - a synthetic form of progestogen

The dosage of these two active ingredients is the same in each pill, which makes Mercilon a monophasic contraceptive pill. The instructions for using this treatment is the same as other monophasic contraceptives, which is detailed in the breakdown below:

  • You should take this treatment for 21 days
  • This is then followed by a 7 day rest period

You will only have immediate protection if you start taking your Mercilon contraceptive treatment on the first day of your period. You can start your course of the treatment between day two and day five of your period, but you will need to use a barrier contraceptive method for the first seven days of the first month after taking Mercilon if it is a new form of contraception.

What happens if I miss a Mercilon pill?

We will provide you with a detailed patient leaflet that will have full instructions on what to do if you happen to miss a pill. The specifics will depend on the number of pills that you miss. If you miss a single pill, take the tablet as soon as you notice. If you miss anymore than this, you may no longer be protected and will have to use a barrier contraceptive method for seven days.

It is important that you take each contraceptive pill at the correct time for optimum effectiveness. Each Mercilon pill will be calendar marked to help you keep track of your treatment cycle, although we would advise that you take each tablet at the same time each day to make this easier.

Are there any side effects?

As Mercilon contains a lower concentration of oestrogen, users will be at less risk of side effects. Whilst weight gain on many other contraceptive pills can be a side effect (often down to water retention that subsides over a couple of months), this medication should also not lead to any weight gain. In some cases it is has even been recorded to lead to minor weight loss during long-term use.

The risk of side effects with this treatment is very small and any that do occur will usually pass after a few weeks, once your body has become accustomed to the ingredients in the pill. Possible symptoms can include:

  • Mood swings
  • Breast tenderness
  • Irregular bleeding

You should consult with a doctor if you persistently experience any side effects, or if you feel that the pill is causing you any other issues.

Who is Mercilon suitable for?

As this treatment uses a lower concentration of oestrogen, it is suitable for women who are more sensitive to this particular hormone. There are some women who should not use this contraceptive pill, for example if you are pregnant or breastfeeding.

Mercilon may also be an unsuitable contraceptive choice if any of the following apply to you.

  • Liver problems
  • Heart problems
  • Severe diabetes
  • History of strokes

Can I take other medications with Mercilon?

Mercilon is a well-tolerated medication that shows no reaction with alcohol or dietary habits. That being said, there are certain medication groups that can impact how this treatment functions. These include:

  • Antibiotics
  • Tetracyclines
  • Barbiturates

When completing your online medical consultation, you must ensure that you include any medication (prescription or over the counter) that you are currently taking, so our medical team can make an informed decision on whether Mercilon is the right contraceptive option for you.

Can I buy the Mercilon contraceptive pill online?

Mercilon is available to purchase online without the need for a face-to-face doctor's appointment or prior prescription. You simply need to complete an online consultation, which will be assessed by one of our team of registered doctors. Once they approve your consultation, a prescription will be sent onto our pharmacy where one of our fully-qualified pharmacists will check your dosage, discreetly package and then dispatch the treatment for free same or next day delivery.
