Hello. My 11 years daughter has started her first periods since last six months. Every month she is suffering from heavy bleeding. So we went to a local gynac and she gave Daflon 500 mg to be taken every first five days of periods twice a day. My daughter is taking this tablet but she is complaining of heavy stomach pain. Also the heavy bleeding is not stopping. As per ultrasound report, the internal organs are all fine. Please advise whether she can continue taking Daflon 500mg and is it the right medicine for stopping heavy bleeding during periods. Thanks. Marry.
