Cyproterone Acetate + Ethinylestradiol - Dosage and How to Use

How should Cyproterone Acetate + Ethinylestradiol be used?

  • Do not stop taking your medication without checking with your healthcare professional.
  • You should take this medication after food.
  • You may start taking this medication on the first or second day of your menses (if this is your first time taking hormonal contraceptives).
  • If you are also using it for contraceptive purposes, a barrier method of contraception e.g. condoms, is recommended for the first 7 days of taking Estelle™-35/35 ED for the first time.
  • You should take one yellow (active) tablet daily for 21 consecutive days, preferably at the same time every day. Each subsequent pack is started after a 7-day tablet-free interval or 7-day period of white (inactive) tablets, during which a withdrawal bleeding usually occurs. This usually starts on day 2-3 after the last yellow (active) tablet is taken and may not have finished before the next pack is started.

What should I do if I miss a dose?
