acyclovir cream

Acyclovir cream is an antiviral medication used primarily for the treatment of herpes simplex virus infections of the skin, including cold sores (herpes labialis). It works by inhibiting the replication of the virus, which helps to shorten the healing time of lesions and reduce the duration of symptoms such as pain, itching, and burning. This topical formulation is designed for external use only and is most effective when applied at the earliest signs of an outbreak, such as tingling or redness, to prevent the progression of blisters.
