Antiviral medications inhibit DNA polymerase in cells where viral penetration has occurred. They have been clinically shown to have a positive impact on the disease healing cycle. The sooner your patient starts treatment with antivirals, the better they work. 1,2
Having fast access to an antiviral prescription may pose an unnecessary delay in therapy that could impact overall healing time. Also, antiviral medications interact with viral proteins directly. In contrast, the non-prescription product 10% Docosanol (ABREVA) does not interact directly, therefore the emergence of docosanol-resistant HSV is unlikely.Prescription antivirals may be most useful to patients who suffer outbreaks very frequently.
