What is Dianette (Co-cyprindiol)?
Dianette is the branded version of this contraceptive pill and Co-cyprindiol is the generic version.
Dianette and Co-cyprindiol work both as combined contraceptive pills and as a treatment for women with bad acne, very oily skin or excessive facial hair. Both contain the same active ingredients: ethinylestradiol and cyproterone acetate.
Only women with bad acne, excessive facial hair or very oily skin should use this method of oral contraception.
Neither of these pills should be taken long-term, and you should stop using this pill when your acne, oily skin or facial hair has cleared up.
How does Dianette (Co-cyprindiol) work?
Dianette and Co-Cyprindiol are combined oral contraceptive pills, which contain both oestrogen and an anti-androgen.
Cyproterone acetate is an anti-androgen, meaning it reduces the number of androgens produced by your skin. Androgens are hormones that control hair growth and the amount of oil produced by the glands in the skin.
As a contraceptive pill, Dianette is over 99% effective at preventing pregnancy when taken correctly. Unlike barrier methods of contraception such as condoms, Dianette and Co-cyprindiol don’t protect against sexually transmitted infections (STIs).

Take one Co-cyprindiol or Dianette pill at the same time every day for 21 days. You will then have 7 days where you don’t take a pill before you start a new strip of pills.
