What is Microgynon 30?

Microgynon 30 is a combined oral contraceptive pill (‘the Pill’).

How does Microgynon 30 work?

These hormones stop you from getting pregnant by working in three ways:

  • Preventing an egg from being released from your ovaries
  • Making the fluid (mucus) in your cervix thicker, which makes it more difficult for sperm to enter the womb
  • Stopping the lining of your womb thickening enough for an egg to grow in it.

How to take Microgynon 30

Microgynon is available in two different pack sizes.

Microgynon 30

This is a 21-day Pill – you take one each day for 21 days, followed by a 7-day break when you take no pills.

Within a few days of taking the last pill from the strip, you should have a withdrawal bleed like a period. This bleed may not have finished when it is time to start your next strip of pills.

You don’t need to use extra contraception during these seven pill-free days – as long as you have taken your pills correctly and start the next strip of pills on time.

Microgynon 30 ED

This is a 28-day pack, 7 of which do not contain any active ingredients.

Some women find it difficult to remember starting a new pack after taking a break and therefore find that it easier to remember to take their pill if they take these placebo pills during the break.

What if I miss a dose?

If you miss a pill, follow these instructions:

  • If you forget to take Microgynon 30 for more than 12 hours after the correct time, then it is advised that you use alternative protection during the 7 days that follow, and the advice in the patient leaflet that comes with the pill under “missed pill”.
  • If it has been less than 12 hours before you took the last pill, then you are still protected and you can continue your course as usual.
  • If you take Microgynon 30ED, and forget to take any of the “inactive” 7-day pills, then just carry on taking the tablets as normal, as you won't be in any risk of pregnancy.

The chances of you falling pregnant if you forget to take your pill depend on your menstrual cycle.

If you are sick (vomit) or have very bad diarrhoea within 4 hours of taking the Pill, your body may not get its usual dose of hormones from that pill.

Please follow the instructions in the patient leaflet on “lost pill”

Talk to your doctor if your stomach upset carries on or gets worse. He or she may recommend another form of contraception.

Side effects & precautions

Microgynon can slightly increase your risks of developing thrombosis, and you should consider an alternative form of contraception if you are in any of the following risk categories:

  • If you are very overweight (body mass index or BMI over 30kg/m2)
  • If one of your immediate family has had a blood clot in the leg, lung or another organ at a young age (e.g. below the age of about 50). In this case, you could have a hereditary blood clotting disorder
  • If you need to have an operation, or if you are off your feet for a long time because of an injury or illness, or you have your leg in a cast.
  • If you gave birth less than a few weeks ago.

The risk of developing a blood clot increases the more conditions you have.

Air travel (>4 hours) may temporarily increase your risk of a blood clot, particularly if you have some of the other factors listed.

It is important to tell your doctor if any of these conditions apply to you, even if you are unsure. Your doctor may decide that Microgynon 30 needs to be stopped.
