  • Dianette tablets contain two active ingredients, cyproterone acetate and ethinylestradiol. This combination of medicines is also known as co-cyprindiol.

    Dianette is an effective combined oral contraceptive pill. Cyproterone acetate is a progestogen derivative, and the other ingredient, ethinylestradiol, is a synthetic version of the naturally-occurring female hormone, oestrogen. It works as a contraceptive by preventing the ripening and release of eggs from the ovaries, as well as increasing the thickness of the cervical mucus, which makes it more difficult for sperm to cross from the vagina into the womb. It also changes the lining of the womb so that it is less suitable for any fertilised eggs to successfully implant in.

    This medicine is as effective a contraceptive as any other combined pill, but it should not be used solely for this purpose. It is used to treat severe acne and hirsutism in women and has the advantage of also providing contraception. This means you do not need to use any other method of contraception while you are using this medicine, unless you miss a pill, have a stomach upset, or are prescribed certain other medicines as well.

    Each tablet has the same dose of hormones in it. One tablet is taken every day for 21 days and you then have a seven day break from pill-taking. During your seven day break, the levels of the hormones in your blood drop, which results in a withdrawal bleed that is similar to your normal period.

    You start the next pack after the seven pill-free days are up, even if you are still bleeding.

    The tablets come in a calendar pack marked with days of the week to help you remember to take a pill every day for three weeks, followed by a week off. You will still be protected against pregnancy in your pill-free week, provided you took all the pills correctly, you start the next packet on time and nothing else happened that could make the pill less effective (e.g. sickness, diarrhoea, or taking certain other medicines).

    It can take a few months of treatment before your acne or hirsutism has completely cleared up and it is recommended that you stop using this medicine three to four months after your skin has got better, rather than use it continuously just for contraception.

    If your acne or hirsutism flares up again, you can take repeat courses.

    You should try and take your pill at the same time every day to help you remember to take it. This is particularly important if you are relying on this medicine for contraception.

    Each tablet should be swallowed with a drink. They can be taken either with or without food.
