But in more severe cases of shingles–– particularly in outbreaks that occur on the face––the prescription antiviral medications Zovirax, Famvir,
and Valtrex can shorten the disease course
and reduce symptoms.
Valtrex can take effect within two or three days. Believe it or not, the over-the-counter heartburn medicine cimetidine (which you probably know as Tagamet) can also help lessen the pain and intensity of the rash. Take 200 mg three times a day with meals, plus 400 mg at bedtime.
