Suggest Medicine For Morphea

31 yrs. old my daughter having a patch on her right leg and it was diagnosed "MORPHEA". On prescription of a doctor, she started to take IMTREX-15MG (METHOTREXATE) in tablet form once in a week since last 10 months. She was hospitalized due various complications such as vomiting and digestive system failure. Now she is fit and decided not to take above medicines on advice of general physician. Kindly advice me other medicine without such complications.
