I am looking for some link between my mother-in-laws drugs and her itching her skin to the point that she has open sores, especially on her back. Been to a dermatologist, did a skin culture and she had a staph infection which was treated with Keflex/3pills/day X 10 days. It was better but not gone. Her meds are: 150 mg Raditidine X2/day, Sertraline HCL 50 mg tablet daily, Carvedilol 3.125 mg tablet daily, Hydroxyzine HCL 10 mg tablet at bedtime, St Joseph low dose aspirine 81 mg/daily, Arthritis Pain Relief 650 mg tablet AM and PM. Any link between all these and the severe itching she has been experiencing for almost a year? She will be 95 in January.
