Husband had a reaction to an antibiotic. Arms broke out in a rash. Went back to Dermotologist. She gave a clobetasol propionate ointment and directions read only use on forearms 2x aday. Clearing up but noticed that a rash appeared on his thighs and chest. There is no fever, itching and no chills. Can I use this oinment on other parts of the body. Called th Derm office we use no answer .Thank you.
