Cold sores might be a problem you have to deal with on a recurring basis for your entire life. That's because they're caused by herpes simplex-1, a virus that medicine currently can't eradicate, according to MayoClinic.com. When you feel a cold sore coming on, you can begin treatment with one of several methods. MayoClinic.com points out that there's no quick or easy fix for cold sores.
Prescription Medications
If you have painful or frequently recurring cold sores, your doctor may prescribe you a medication designed to help your body suppress the herpes simplex-1 virus. The most common suppressive therapy drugs are acyclovir, famciclovir and valacyclovir, according to MayoClinic.com. These are oral medications that are also prescribed for genital herpes infections. If you take these medications daily, you may reduce the number and duration of cold sores you get each year,according to the National Institutes of Health.
Over-the-Counter Remedies
MotherNature.com recommends an over-the-counter supplement called lysine, an amino acid, to help prevent and get rid of cold sores. The website points out that 2,000 to 3,000 milligrams of lysine taken daily can help prevent cold sore outbreaks. Doubling that dose when you feel a cold sore coming on can help shorten the cold sore's duration. Lysine may inhibit normal growth, so it's important to talk to your doctor before taking it. If your cold sore causes pain, the National Institutes of Health recommend taking a pain reliever, like acetaminophen, or aspirin.
Home Remedies
While it's true that nothing can make your cold sore go away overnight, home remedies may be able to make you more comfortable, minimize your cold sore's appearance or shorten your cold sore's duration. MayoClinic.com recommends alternating hot and cold packs to combat inflammation and pain. MotherNature.com points out that the virus causing your cold sores needs a common ingredient in foods like chocolate, peas, nuts and beer called arginine to thrive. Avoiding these foods can help fight your cold sore. Always resist the urge to poke, squeeze or pick at your sore.
