About Diane-35

Diane-35 contains two sex hormones: cyproterone acetate, a progestogen, and ethinyl estradiol, an oestrogen.

Diane-35 is a contraceptive to prevent pregnancy in women. Diane-35 is also used for the treatment of signs of physical male characteristics caused by the male sex hormone, androgen, produced by in women in small amounts (androgenisation), such as:

  • Acne, especially severe acne with oily skin and flaking (seborrhea) or with inflammation or formation of nodules (pustular acne, nodular acne).
  • Hair loss caused by excess androgen production (androgenetic alopecia).
  • Excessive growth of facial or body hair (known as hirsutism) of a mild to moderate degree.

Cyproterone counteracts the action of male sex hormones, which reduces the symptoms.

Diane-35 is not prescribed for prolonged periods when used solely as a contraceptive. The doctor will tell you how long you need to use this medicine. The length of treatment depends on the severity of the condition. A course of treatment typically takes several months.


Like most other contraceptive pills, Diane-35 is taken for 21 consecutive days with seven days off.

  • Take one tablet daily. Follow the arrows that are printed on the back of the strip until all the tablets have been taken.
  • After 21 days, you have a seven-day break from pill-taking.
  • During this break you will get a withdrawal bleed.
  • Always start a new blister pack on day 8, even if you are still bleeding.

The tablets can be taken with or without food at about the same time every day.

Taken too much/forgot to take/stop taking Diane-35

If you swallow too many Diane-35 tablets at the same time, or you think a child may have swallowed some, contact your doctor or pharmacist immediately.

Missed a dose of Diane-35?

  • If you miss a tablet and take the missing tablet within 12 hours of missing it, you should still be protected against pregnancy.
  • If you are more than 12 hours late, there is risk that Diane-35 is less effective at preventing pregnancy. Whether or not this is the case depends on when and how many pills are missed. If you are more than 12 hours late follow the instructions on the package leaflet.

Note: if you vomit or have severe diarrhoea, the active ingredient may not have been completely absorbed. If you vomit within three to four hours after taking your Diane-35 tablet, follow the instructions for missed tablets. If you have severe diarrhoea, contact your doctor.

Stopping Diane-35: do not stop taking Diane-35 without consulting a doctor first.
