Should I start taking diane 35 for the beginning of pcos? Age: 18. Missed my periods for 2mths and again for 2 months. Taken primolut.

Sure. Diane 35 would be effective for the cycle control and ovarian suppression that is needed with pcos and will also offer contraception, if needed, as well as predictable cycles with less cramps and less blood loss.
Not yet! See your physician to do a comprehensive work-up. Pcos is a diagnosis of exclusion and other abnormalities should be assessed including thyroid-prolactin-adrenal abnormalities. In addition, glucose tolerance testing should be done. For pcos, oral contraceptives are appropropriate, but if acne- excessive hair growth, sugar abnormalities are present- other medications may be indicated.
