DOCOSANOL

DOCOSANOL
(doc'os-a-nol)
Abreva
Classifications: antiviral-like;
Therapeutic: antiviral-like

Pregnancy Category: C

Availability

10% cream

Action

Docosanol inhibits viral replication by interfering with the early intracellular events surrounding viral entry into target cells. It exhibits preferential activity against lipid-enveloped viruses that use fusion mechanisms for entry into target cells. This renders such target cells less susceptible to viral fusion or entry.

Therapeutic Effect

Believed to exert its antiviral effect by inhibiting fusion of the HSV (herpesvirus) envelope with the human cell plasma membrane, therefore making it difficult for the virus to enter the cell and replicate.

Uses

Treatment of herpes simplex infections of the face and lips (i.e., cold sores).

Contraindications

Hypersensitivity to docosanol or any of the inactive ingredients in the ointment; immunosuppressant patients; pregnancy (category C); lactation.

Cautious Use

Safety and efficacy in children are not established.
