What is Microgynon 30?
Microgynon 30 is an oral contraceptive. It is a combination of two active ingredients: levonorgestrel, a progestin, and ethinyl estradiol, an oestrogen. These hormones prevent ovulation and change the quality of the womb lining, making it less likely that a fertilised egg can implant there. They also increase the thickness of the natural mucus at the neck of the womb, which makes it more difficult for sperm to cross from the vagina. If taken regularly and correctly, Microgynon 30 is highly effective at preventing pregnancy.
What is Microgynon 30 used for?
This pill is a contraceptive. In other words, Microgynon 30 is used to prevent pregnancy. However, it is also prescribed to treat menstrual pain and heavy bleeding during menstrual periods. This is because Microgynon 30 produces a monthly withdrawal bleed that is much lighter than a woman’s usual period.
How to use Microgynon 30
Like other contraceptive pills, Microgynon 30 is only effective when taken daily at a specific time. If you miss a dose, vomit after taking a pill or have severe diarrhoea, the pill may not have been fully absorbed into your bloodstream and thus less effective. For precise instructions on what to do if this is the case, see the package leaflet. If necessary you should use additional contraception to avoid getting pregnant.
This contraceptive is available in two forms: Microgynon 30 and Microgynon 30 ED. Dosage is as follows:
Microgynon 30 comes in strips of 21 tablets. One tablet is taken every day for 21 days and you then have a seven day break from pill-taking. During this seven-day break, the levels of the hormones in your blood drop, which results in a withdrawal bleed. You start the next pack after the seven pill-free days are up.
Microgynon 30 ED
Microgynon 30 ED comes in strips of 28 tablets. It is an everyday pill and there is no pill-free week. Each strip contains 21 active tablets and seven inactive tablets of a different colour (tablets without the active ingredient). During the seven days of taking the inactive tablets, the levels of the hormones in your blood drop, which results in a withdrawal bleed. You start the next strip straight away without a break.
Some women find Microgynon 30 ED easier to use because you do not have a pill-free week. Both forms, Microgynon 30 and Microgynon 30 ED, contain the same active ingredients and essentially work in the same way.
Microgynon 30 can cause side effects. Most side effects will disappear within a number of weeks once the body adjusts to the hormones. Reported side effects include:
- Breast tenderness;
- Gastrointestinal symptoms;
- Menstrual spotting or breakthrough bleeding;
For more information on possible side effects, see the package leaflet.
