Can be prevented.: Your immunology is weak against the herpes virus. Valtex daily can help. Natural answers include lysine and zinc (50mg of zinc gluconate)!

You can't: There's no cure for hsv infection and the blisters may recur sporadically — often in response to stress or a weakened immune system. Antiviral medications can help cold sores heal more quickly and may reduce the frequency of recurrences. Once you've had an episode of herpes infection, the virus lies dormant in nerve cells in your skin and may emerge again as an active infection.

some times Lysine (an amino acid) taken on a regular basis will help, if you have a lysine deficiency. But this is not a cure, only an aid if there is a deficiency.

Easy tips: To prevent cold sores from occurring wash hands often. Maintain a healthful lifestyle (regular exercise, nutritious diet, adequate sleep, keeping stress at bay). Keep lips well moisturized & apply sun screen to the areas that your cold sores normally pop up. Talk with your physician about supplementing with lysine.

Are there any good ways to prevent cold sores?

Dr. Robert Kwok

Antivirals if needed: Since herpes type 1 virus infections happen to the great majority of the american population, it is extremely hard, if not nearly impossible, to prevent oneself from getting infected during his lifetime. So, if one has cold sores, and just mild ones, 1-3 times a year, no prevention is recommended. For people with widespread or frequent outbreaks, doctors may prescribe daily antiviral medicines.

Be Well: Give yourself lots of tender loving care: eat right, exercise, get rest, balance work/play. When life's out of whack, then we don't fight off infection as well ... And cold sores can break out. Think of it as a yellow flag warning that something's out of balance. 4 or more outbreaks of cold sores in a year? Talk with your doc about daily antiviral rx to prevent more cold sores.

Not sure you can -: Cold sores are caused by a herpes virus and is transmitted by direct contact. The problem is that the contact doe not have to be with a human. It can be carried on an inanimate object like a fork or spoon, or even a drinking glass. In a perfect world where "clean" means clean you might be safe but in reality you can be exposed to the virus despite your best efforts to avoid it. Good luck -.

Virus Infection: Cold sores are typically caused by virus infections that spread from person to person. Some viruses can live in the body and reactivate even if you haven't been re-exposed. If you have a history of cold sores, and they occur frequently, your doctor may be able to prescribe medication to suppress the virus from flaring.
