Diane 35 Tablets (21 tablets) contain Cyproterone Acetate (2mg) and Ethinylestradiol (0.035mg). This combination is primarily used for the treatment of hormonal acne, seborrhea, and excessive hair growth (hirsutism) in women. It is also used as an oral contraceptive due to its ability to suppress ovulation. It works by regulating hormone levels and reducing androgen activity.
