Remedies and Treatment for Cold Sores
Posted in Skin Care on December 30th, 2008 by debojit – Be the first to commentWhile there is no cure for cold sores (fever blisters) there are medications and remedies that can be useful in their treatment and management. There are several medications available to treat cold sores. Some are used topically and others are taken orally. Different types of over-the-counter cold sore medications are also available. Some common cold sore home remedies also provide relief from cold sores. Cold sores are best treated as early as possible. Starting a medication when prodromal symptoms such as burning, tingling, or redness start gives the best chance of keeping the cold sores from developing or shortening their course.
Cold Sore Treatment
The first outbreak of any herpes simplex infection is worse than recurrent infections. A first outbreak of oral herpes should be treated with oral medications, while recurrences can be treated with topical medications.
Prescription drugs for Cold sores.
There are prescription drugs (Rx) for the treatment of cold sores. The currently FDA-approved prescription anti-viral

Cold sore remedies
drugs are known as nucleosides act by offering the herpes virus a defective nucleoside building block (“fake DNA”). The nucleoside drugs (acyclovir and drugs based on acyclovir such as Zovirax, Valtrex, Denavir, Famvir, etc.) act by interfering with viral replication. Many people found these drugs helpful in decreasing the incidence, duration and severity of lesions as well as decrease asymptomatic viral shedding. However, the effectiveness of these drugs in treating the virus is not universal.
The effectiveness of these oral nucleosides drugs in killing the virus is not conclusive. The most widely used medication is Acyclovir which is commonly known as Valtrex (tablet form) and Zovirax, the topical cream, which is applied directly to the lesion. A second generation hybrid drug of Acyclovir is Valacyclovir. Valacyclovir achieves higher blood levels, while Famvir, another anti-viral agent is more rapidly absorbed into the cells and persists longer. The superiority over acyclovir at this time is inconclusive. These are suppressive drugs and are taken prophylactically to prevent viral shedding and outbreaks. Suppression therapy, taking medication every day to prevent outbreaks, is not yet FDA-approved.
Over-the-counter medications for cold sores.
Many over-the-counter (OTC) cold sore medications are primarily palliative in nature intended to relieve the symptoms of cold sores such as pain, itching, and burning. Other OTC products help to develop an environment which restrains the continued development of the cold sore lesion or help to promote its healing. A third category of OTC medications possesses properties that directly hinder the herpes virus’ ability to form a cold sore.
Home remedies for cold sores.
Though none of the remedies listed below have been scientifically proven to cure or shorten the duration of cold sores. Still many people do feel that they find them to be beneficial.
Apply ice to cold sores.
Ice has twofold benefit. Applying ice (for five to ten minutes each hour) during the tingle stage will lower the temperature of the tissue where the cold sore is forming. This temperature reduction will reduce the area’s metabolic rate and will interrupt the cold sore’s development. Secondly, intermittent application of ice to a cold sore can act as a numbing agent and therefore lessen its pain and itching.
Apply a tea bag to the infected area
Tea contains tannic acid which has antiviral properties. Placing a tea bag on a cold sore when it first begins to form can possibly help iing minimize the extent to which the lesion would have developed. The moistened tea bag (regular black tea like that used to brew ice tea) should be placed on the area where the cold sore is forming for a few minutes every hour.
Moisturise the sore area with petroleum balm
Moisturizing agents such as petroleum jelly can be applied to cold sore scabs. This will moisturize, soften and to prevent them from cracking and bleeding.
Nutritional supplements.
It is suggested that taking l-lysine supplements, an amino acid, can reduce the number of outbreaks of cold sores that a person experiences. This fact, however, has not been conclusively proven by medical research. Lysine supplements should only be taken in response to a recommendation by a health care professional.
Herbal remedies.
Herbal antiseptics Sage and Tea Tree Oil and the herbal sedative Violet has been suggested as a treatment for cold sores. Since, herbal treatments must be used appropriately; therefore it should only be used in response to a recommendation by a health care professional.
Preventing cold sores.
Practicing a few common sense things will help you to minimize the number of cold sores you get.
• Exposure to bright sunlight can trigger cold sores so, when outside you should shield your face from the sun with a hat. Additionally, use a lip balm that contains a sun screen having an SPF value of 15 or greater.
• Injury to the lips can trigger cold sores. Minimize the potential for lip damage associated with chapping by applying a moisturizing lip balm.
• The cold sore virus (HSV-1) is very sensitive to soap and warm water. If you have a lesion, the best way to help prevent spread of the virus is frequent hand washing with soap and warm water.
• A soft, bland diet is recommended to avoid irritation and allow the ulcers to heal.
• To prevent infecting others, kissing and intimate contact should be avoided while any symptoms of an active cold sore lesion are present.
• Please remember that all stages of cold sore formation should be considered to be contagious. So to avoid spreading the herpes virus (either to other people or other parts of your own body), after applying any medication or treatment to a cold sore you should always wash your hands.
