Scoping review to map evidence on mechanism of action, pharmacokinetics, effectiveness and side effects of centchroman as a contraceptive pill.

The scoping review shows that studies with robust designs and conducted in international context are lacking. Insufficient evidence exists on centchroman use as a postcoital contraceptive pill. The broad uncertainty in range of side effects and effectiveness in the studies implies insufficient evidence to make global recommendations on centchroman that is currently licensed as a contraceptive in India.
