Cold sores are ulcerative lesions that are caused by an underlying viral infection. These lesions – typically found in or around the mouth – can open up and leak fluids if not properly treated. In addition, they can cause pain and a burning sensation- leading to significant suffering. Below are some frequently asked questions about this condition as well as some treatment options.<\/p>\n
What causes cold sores?<\/strong> How long do cold sores last?<\/strong> How can I prevent cold sores before they occur?<\/strong> What are some common treatments for cold sores?<\/strong> Can I use Denavir on the cold sores in my mouth?<\/strong> Is Denavir safe?<\/strong>
\nAs mentioned, cold sores occur in the presence of an underlying infection with the Herpes Simplex Virus. When the virus tracks to the skin’s surface, lesions occur. Outbreaks can occur for a variety of reasons. At times, it can be as simple as the body’s immune system overworking to fight off invading viruses. But cold sores can also be caused by fatigue, stress and hormonal changes. Food allergies, weight loss and hormonal changes have also been known to cause cold sores. The possible causes are nearly endless.<\/p>\n
\nGenerally, cold sores only last for about 7 to 10 days, but it’s not uncommon to experience recurrent outbreaks a few times each year. Fortunately, most occurrences of cold sores<\/a> can be cured or prevented.<\/p>\n
\nIf you know what caused your cold sores to occur, avoid those situations in the future if at all possible. For instance, if they are caused by fatigue, try to get the proper amount of rest. If it’s caused by a chemical imbalance or vitamin deficiency, monitor your diet closer and ensure appropriate intake of vitamins and minerals each day. If stress causes a recurrence of your cold sores, avoid stressful situations.<\/p>\n
\nThere are several different treatment options for cold sores. One of the more effective medications commonly used to treat cold sores is Denavir. This is a topical antiviral medication that – when used as prescribed – is one of the safest and most effective treatments to eliminate those unsightly lesions around the mouth.<\/p>\n
\nNo. Denavir should only be used on lesions appearing on the lips and face and should be applied at the first sign of symptoms. Using it on the inside of the mouth or the nose could be dangerous to your health.<\/p>\n
\nDenavir is safe when used under the supervision or direction of a physician. Pregnant women should always check with their doctor before using Denavir as it is pregnancy category B as rated by the FDA. It’s also unknown if the medication passes into a mother’s breast milk. As with any treatment, check with a doctor before deciding to use it.<\/p>\n
