Diane-35 ED is used for the treatment of signs of androgenisation in women, such as severe acne or for excessive growth of facial or body hair (known as hirsutism) of a mild to moderate degree, where no underlying cause has been found. Diane-35 ED can also be used as a contraceptive to prevent pregnancy in women who are taking it for the treatment of signs of androgenisation as described above. Diane-35 ED contains a progestogen and an oestrogen hormone, and therefore works similarly to the combined oral contraceptive birth control pill, also known as ‘the Pill’. It should not be used in combination with another hormonal contraceptive.
