Hi thanks for the query.
Althea pill has cyproterone
acetate which has antiandrogen
activity and hence more side effects. It is mainly used when patients have acne/ PCOS also.If you don't have these, then you can try other pills with safe progesterone
Pills should be started on day 1 of menstrual cycle an the pack should not be left in between for its complete contraceptive
Hope this information is helpful and informative to you.
