Hi,
Duphaston contains dydrogesterone that is used in the treatment of various menstrual problems such as irregular, abnormal or painful menstrual bleeding, infertility, endometriosis etc. But like other medications this medication has some side effects of its own. It may cause menstrual irregularities like heavy or scanty bleeding during periods,
vaginal discharge, vaginal bleeding, absent or more frequent periods, prolonged or short menstrual periods, irregular
uterine bleeding, spotting or breakthrough
bleeding between periods etc.
These side effects are mild and usually go away over time. But if these side effects persist for long or bother you then you should consult your doctor first for
medical help. It is possible to become pregnant while taking this medication, so If you have any doubt then you can undergo urine for pregnancy test 7 days after the next missed period.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Zubayer Alam, General And Family Physician
