Which contraceptive is more effective - Microgynon 21 or Cyprodiol?

Both Microgynon 21 and Cyprodiol are combined contraceptive pills. Both provide very high effectiveness in preventing pregnancy.

It is worth noting that Cyprodiol, in addition to its contraceptive effect, also has indications for the treatment of skin diseases such as acne, very oily skin and excessive hair in women who are of childbearing age and want to use hormonal contraception to prevent pregnancy. Side effects are adverse effects that may or may not appear after each medication. Each possible side effect has a statistically defined frequency of occurrence in the patient population taking the medicine, but it is not possible to predict in advance whether, in whom and what side effects will occur. It may turn out that a drug with a longer number of side effects will not cause any of them, and a preparation with a shorter one will ultimately turn out to be poorly tolerated.
