There are now a lot of medications for rash treatment, ranging from over the counter mild treatments to powerful antibiotics by prescription only.

Two over the counter meds that often will take care of rash problems are Zanfel wash:

And Generic Hydrocortisone Ointment. Old advice was to avoid Hydrocortisone cream in favor of the ointment, but not sure if that still prevails.
