What Is A Cold Sore (Fever Blister)?

A cold sore is a sore which usually occurs in the lip and nose region. They are caused by an infection of the virus, Herpes Simplex Type 1. The first symptoms of cold sores are tingling, itching or burning sensations and then blister formation occurs. If the blister bursts, the lesion may become infected with bacteria. After the first Herpes Simplex Type 1 infection, the virus remains dormant in the tissue. You can never kill the virus which causes cold sores and you may suffer from them for a lifetime. Recurrent cold sores are caused by reactivation of the virus by various precipitating factors including: sunlight, fever, stress, respiratory tract infections and menstruation.


VIRASOLVE Cold Sore Cream is a topical treatment for the relief of the symptoms of cold sores. It contains three active ingredients including: idoxuridine 0.5% w/w, lignocaine hydrochloride 2% w/w and benzalkonium chloride 0.5% w/w.

Idoxuridine is an antiviral agent which is active against Herpes Simplex Type 1 and, if used early enough, at the first sign of an oncoming lesion can prevent further development of the cold sore.

Lignocaine hydrochloride is a local anaesthetic which provides relief of the pain and itching associated with cold sores.

Benzalkonium chloride is an antibacterial agent which helps control bacterial infections in broken cold sores.
