acyclovir + valacyclovir + topical corticosteroid

The concept of a combination therapy involving acyclovir, valacyclovir, and a topical corticosteroid for treating herpes simplex virus infections, particularly cold sores (herpes labialis). While antiviral medications (acyclovir or valacyclovir) are used with topical corticosteroids, there is no single commercial product that contains all three active ingredients together. The combination approach aims to target viral replication through antivirals and reduce inflammation through corticosteroids. Studies have examined combinations like acyclovir with hydrocortisone (e.g., Xerese) and valacyclovir with topical corticosteroids.
