Blistex (Docosanol)
Blistex (Docosanol) Uses, Dosage, Side Effects, Food Interaction and all others data.
Blistex (Docosanol) exerts its antiviral effect on HSV by inhibiting fusion of the virus envelope with host cell plasma membranes, resulting in inhibition of viral entry into cells and subsequent viral replication.
Blistex (Docosanol) is a saturated 22-carbon aliphatic alcohol which exhibits antiviral activity against many lipid enveloped viruses including herpes simplex virus (HSV). Blistex (Docosanol) speeds the healing of cold sores and fever blisters on the face or lips. It also relieves the accompanying symptoms, including tingling, pain, burning, and itching. Blistex (Docosanol) cannot, however, prevent cold sores or fever blisters from appearing.

Uses
Blistex (Docosanol) 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 (Docosanol) is also used to associated treatment for these conditions: Cold Sore
How Blistex (Docosanol) works
Blistex (Docosanol) 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.
Dosage
Blistex (Docosanol) dosage
Adults and Children of 12 years of age and older: Apply 5 times a day until healed. Treatment should be begun at earliest signs or symptoms of herpes infection (Blisters, open sores, pain in the infected area, itching, burning, tingling or numbness).
Side Effects
Generally Blistex (Docosanol) is well tolerated. Rarely burning, dryness of skin, itching, rash, swelling & headache are seen after administration of Blistex (Docosanol).
Toxicity
Symptoms of overdose include headache, abdominal pain, increased serum lipase, nausea, dyspepsia, dizziness, and hyperbilirubinemia.
Precaution
Cream should only be applied to lips and face. Avoid application in or near the eyes. Emphasize hand washing following application. Do not touch the lesion to prevent spread to others or to other parts of the body.
Herpes infection is a recurring disease. Viral reactivation may be triggered by ultraviolet radiation or sun exposure, stress, fatigue, chilling. Other possible triggers include fever, injury, menstruation, dental work and infectious diseases (cold, flu).
Patients are advised to notify health care professionals if lesions do not heal in 14 days or if fever, rash or swollen lymph nodes occur.
