What is Dianette?
Dianette is a combined contraceptive pill that contains the active ingredients cyproterone acetate and ethinylestradiol.
When taken correctly, the combined contraceptive pill is 99% effective at preventing pregnancy.
You can only Dianette on prescription.
What is Dianette used to treat?
Dianette is a contraception pill used in the prevention of pregnancy. It will not protect you from sexually transmitted diseases (STDs); you should still use a condom to prevent the risk of STDs.
Dianette is also prescribed as a treatment for women who suffer from skin conditions like acne, very oily skin and excessive hair growth. It is normally only prescribed to treat skin conditions when you have not responded to other anti-acne treatments, such as topical creams and antibiotics.
How does Dianette work?
Dianette contains the active ingredients cyproterone acetate and ethinylestradiol; this combination is known as co-cyprindiol. Cyproterone acetate is an anti-androgen and ethinylestradiol is a synthetic version of oestrogen. These ingredients work together to prevent pregnancy in three different ways:
- Stopping the ovaries from releasing an egg
- Thickening the mucus in the cervix, making it much harder for sperm to enter the womb
- Preventing the womb lining from thickening enough for an egg to grow within it
As a treatment for acne, Dianette works to reduce the action of androgens (male sex hormones that stimulate hair and skin growth, as well as oil production). This reduces sebum production and excessive hair growth. You should notice that your skin is less oily after taking this medication for a few weeks, although it can take up to three months for Dianette to take a strong effect.
