The difference, explained

Diane-35 is Bayer's original brand; Althea is a lower-priced brand with the same active ingredients at the same dose, in the same 21-tablet pack with a 7-day break. A third brand, Cybelle, has the same formula too.

Cyproterone acetate pills are licensed in Europe for moderate to severe acne and excess hair growth linked to androgens, usually after other treatments, and should not be taken together with another hormonal contraceptive.[src] They also prevent pregnancy. The European Medicines Agency reviewed this family in 2013 and found the benefits outweigh the risks in that group, including a blood clot risk that is higher than with levonorgestrel pills.[src]

Because the actives and dose are identical, you should expect the same effect on acne and the same side effect profile. Inactive ingredients and tablet appearance can differ. Filipinas on Reddit compare the two often, especially in PCOS groups, and most of the discussion is about price.[src] Over a year the gap adds up to several thousand pesos.

Which may suit you

  • Diane-35 may suit you if: You prefer the original brand, or your doctor prescribed it by name and you want to stay on it.
