Blistex (ANTIVIRALS)

Uses

Blistex (ANTIVIRALS) cream is used for the topical treatment of acute and recurrent oral-facial Herpes simplex episodes (Herpes labialis or cold sores or fever blisters).

Blistex (ANTIVIRALS) is also used to associated treatment for these conditions: Cold Sore

How Blistex (ANTIVIRALS) works

Blistex (ANTIVIRALS) works by inhibiting fusion between the human cell plasma membrane and the herpes simplex virus (HSV) envelope, thereby preventing viral entry into cells and subsequent viral replication. Unlike other cold-sore antivirals, docosanol does not act directly on the virus, and as such it is unlikely it will produce drug resistant mutants of HSV.
