While there is no cure for the simplex virus there are a number of cold sore treatments available that relieve the pain and discomfort associated with cold sores and blisters. Treatments range from the prescription medication that only a doctor can authorize to over the counter treatments, as well as home remedies that may help treat the discomfort of a cold sore. It is recommended if you do have an outbreak to keep the blister clean to avoid additional infection. Eating a bland diet is also recommended in order not to make any infection near your mouth aggravated with spicy foods or caffeine.
Many over-the-counter cold sore medications are just intended to relieve the symptoms of cold sores, including the pain and itchiness. Other OTC products help to boost your bodies immune which is thought to inhibit the development of cold sores and promote healing. Yet another type of medication has properties that directly interfere with the herpes virus’ ability to form cold sore lesions.
Topical docosanol is used to treat the symptoms of herpes simplex virus infections around the mouth. This means that the severity and the duration of a cold sore can be seriously reduced. Although topical docosanol will not cure herpes simplex, it may help relieve the pain and discomfort and may help the sores heal faster.
Clinical trials have shown that it can reduce the required healing time for cold sores by up to one day. Most products that contain docosanol as an active ingredient will recommend that the treatment is applied to the effected area repeatedly, and should be applied as soon as a suspected outbreak is happening (also know as the “tingle” stage).Products that contain antiviral properties may limit herpes ability to form cold sore lesions.
Antibacterial agents will not have any affect the herpes virus but can be beneficial when used on a cold sore as they may help prevent secondary infection in the exposed area. Other over the counter medications may contain numbing agents to help prevent painful effects of cold sores such as burning or itching. Active ingredients in these products may include benzocaine, lidocaine, benzyl alcohol, camphor, and phenol.
Lip Balms containing petrolatum are often used by cold sore sufferers to help moisturize and soften cold sores, and so they are much less likely to crack and bleed. It has also been noted that some people have cold sores that react to sunshine; these are often prevalent on the bottom lip of sufferers. If this is the case the use of zinc oxide or another sunscreen protection is recommended.
Applying Ice to your cold sore is a common practice and if done at the correct time may help inhibit the development off the lesion. If applied early enough, when the “tingling” sensation occurs cooling the area will lower your metabolic speed and inhibit the viral progress accordingly.
Applying a damp tea bag to the area where the faver blister is forming is another home remedy that is quite common practice. Tea contains tannic acid which contains antiviral properties (some medications for cold sores contain tannic acid). As with any homemade remedy the earlier you apply it better the chance of success with the result.
