Diane-35 is a combined hormonal pill containing two hormones: ethinylestradiol 35 micrograms (a synthetic estrogen — the source of the "35" in its name) and cyproterone acetate, an anti-androgen. This second hormone is what sets Diane-35 apart from typical combined pills that use an ordinary progestin — it directly blocks male-hormone receptors in oil glands and hair follicles, reducing excess oil and abnormal hair growth, while also suppressing ovulation for contraception. This original formula was developed and registered in Europe since the 1980s before becoming widely used worldwide, including in Thailand, and remains the reference formula that other cyproterone-based pills are compared against. Diane-35 should not be taken together with another hormonal pill or hormone supplement at the same time, as this would provide an unnecessary excess dose of hormones.

Diane-35 has two main indications: (1) treating moderate to severe acne caused by excess androgen hormone, especially acne that hasn't improved with topical treatment or antibiotics, often accompanied by excessive oiliness and inflamed breakouts around the jawline and chin, and (2) hirsutism — abnormal hair growth on the face, chest, or back in women, which is often also a sign of higher-than-normal androgen levels. It also provides contraception when taken correctly and continuously, making it suitable for women of reproductive age dealing with hormone-related skin or hair issues who also want contraception. It is not recommended for someone who only wants contraception without a genuine skin or hair concern, since lower-risk options exist for that purpose.

Diane-35 comes only in a 21-tablet strip (no 28-tablet version like some other brands) — take one tablet daily at the same time for 21 days following the arrows printed on the strip, then stop for 7 days before starting a new strip. During the pill-free week, a period-like withdrawal bleed occurs as with typical combined pills. Start the first tablet on day one of the menstrual cycle so contraceptive protection covers from the first tablet; starting on another day requires backup contraception, such as condoms, for the first 7 days. Anyone switching from another combined pill should start the first Diane-35 strip right after finishing the previous pack, with no gap in between, so contraceptive coverage is not interrupted.

Common side effects are similar to other combined hormonal pills: nausea, headache, breast tenderness, mood changes, slight weight changes, reduced libido, and spotting during the first few cycles. Some people may notice patchy skin darkening (melasma) on the face, especially with sun exposure. Most of these improve within the first 2-3 cycles as the body adjusts. Seek medical attention immediately if you experience one-sided leg swelling and pain, severe chest pain, difficulty breathing, or a severe headache with blurred vision, as these may signal a blood clot.

Do not use if you have a history of venous or arterial blood clots, cardiovascular disease, migraine with aura, breast cancer or other hormone-sensitive cancers, severe liver disease, pregnancy, or while breastfeeding. Smokers, especially those over 35, face higher clot risk and should avoid this formula. Certain anticonvulsants and rifampicin-type antibiotics can reduce the contraceptive effect of Diane-35, so always tell your pharmacist about any other medicines you are taking. Because this formula carries a slightly higher blood clot risk than other combined pills, it should be chosen mainly when there is a genuine acne or hirsutism indication, not simply as a first-choice contraceptive without a skin or hair reason.

Diane-35 uses cyproterone acetate, a stronger anti-androgen than the progestins in other brands, suiting those whose main concern is acne or hirsutism rather than contraception alone. This differs from Yasmin, which uses drospirenone focused on reducing water retention and oiliness without as strong an anti-androgen effect, better suited to those mainly concerned about pre-period bloating, and Preme, a gentle low-dose progestin formula suited for first-time users with fewer side effects. As the original branded formula, Diane-35 also remains the reference point that lower-priced cyproterone-based pills on the market are specified against. In short: choose Diane-35 when acne or hirsutism is the main concern, Yasmin for water-retention relief, and Preme for an easy first pill.

Full contraceptive protection begins after the first 7 consecutive tablets of the first strip (if started on day one of the cycle). The acne- and hirsutism-reducing effects take much longer since they depend on long-term hormonal rebalancing rather than acting like a fast-acting topical acne treatment — facial oiliness and acne typically start improving after the first 2-3 months, while visible improvement in excess hair growth usually takes 6-9 months of continuous, uninterrupted use. If use is stopped partway through, these benefits usually fade gradually over the following cycles.
