Valtrex Tab 500 mg is an oral prescription medicine. It is mainly used to treat skin or nerve-related infections caused by certain viruses. As it contains prescription-only ingredients, the specific indications, treatment duration, and daily dosage — for example, in cases of shingles — must be strictly determined according to a doctor’s professional clinical diagnosis.
Its main function is to treat and prevent skin and mucosal infections caused by specific herpes viruses. Examples include the treatment of shingles, also known as herpes zoster; the treatment of herpes simplex infections, including first episodes or genital herpes; and the treatment of recurrent herpes simplex infections, such as cold sores or recurrent genital herpes.
