She is Alpha chain thalesemia minor Whenever she takes this tablet, she does excess vomiting, due to which whatever she eats, comes out, and nutrients are not retained. We discontinued this tablet for couple of days, she was fine, however nails of toes, started turning purple, due to less oxygen supply, so she again took this tablet, but again this cycle of excess vomiting started. kindly advise. Also suggest some alternate iron medicine.
