Diane 35 Tablet is a hormonal medicine containing Ethinyl Estradiol and Cyproterone. It is used to treat conditions like acne, alopecia (loss of hair), hirsutism (excessive facial hair growth in women), etc. Ethinyl estradiol has a very similar action to the female sex hormone, estrogen, produced by the ovaries. Thus it helps in treating irregular periods. Diane 35 Tablet is sometimes used for terminating a pregnancy. Do not use this medicine with other hormonal pills without consulting your doctor.
