If you have a rash, I would recommend getting a prescription steroid ointment or cream or solution (fluocinonide ointment, Clobetesol soln.,
and some others)
and also a prescription for an oral
antihistamine. Hydroxyzine (Atarax) works well usually. If your rash is bad, the over the counter stuff is not going to work. Plus, one needs to get on top of the rash immediately because it can and will snow ball.
