Dianette tablets
Dianette is a combined oral contraceptive pill (COC) that contains cyproterone acetate and ethinylestradiol. It is primarily prescribed for women who require both contraception and treatment for acne or symptoms caused by excess androgens (male hormones).
As a contraceptive, Dianette works in three key ways: it prevents ovulation (the release of an egg), thickens cervical mucus to make it harder for sperm to reach the egg, and thins the lining of the uterus to reduce the likelihood of implantation. When taken correctly, it provides highly effective protection against pregnancy.
Unlike standard contraceptive pills, Dianette also has anti-androgen properties, which can help reduce symptoms such as acne and excessive hair growth. However, it should only be used for contraception in women who also require treatment for these conditions.
