second, if you get the correct meds, maybe they will control the
rash and itching. I have had a very itchy generalized
rash and was taking over the counter stuff (benadryl, hydrocortizone cream). The rash got so bad those meds were doing nothing. I had to get some prescription meds (fluocinonide ointment to apply, hydroxyzine tabs. for the itching (bedtime), clobetesol liquid for my scalp itching, and Zyrtec for am (zyrtec is over the counter, or I could use claritin for am).
