Herpes simplex, a highly contagious virus that remains in your body for life, causes fever blisters, or cold sores. Herpes simplex infects between 62 and 85 percent of American adults, according to the University of Maryland Medical Center. While your fever blister will typically heal without intervention, there are several home remedies, over-the-counter medications and antiviral drugs that may moderate the affects and speed healing.
Home Remedies
When the onset of a fever blister catches you by surprise, try as your first line of defense the application of an ice pack or cold compress to reduce swelling. Baking soda compresses may help to reduce itching. Use honey, a natural source of antibacterial and antiviral properties, to promote healing.
Topical Applications
Apply over-the-counter lip balms to keep your fever blister moist. To speed healing, look for ointments with antiseptic and antimicrobial agents that kill surface bacteria.
Pain Relievers
If your fever blister stings, look for topical treatments that contain the anesthetic benzocaine. Take aspirin, ibuprofen or acetaminophen for pain relief. Do not give aspirin to children or teenagers with flu symptoms or to infants.
Supplements
L-lysine, a natural amino acid with antiviral properties, may reduce the frequency of outbreaks, according to Medline Plus. Poultry, fish and potatoes all contain L-lysine; also look for it in ointment or tablet form.
Herbs
MedHerb.com suggests the herb lemon balm as an effective remedy for fever blisters. For ease of application, dab a warm tea bag on the blister several times each day. Also look for herbs with antiviral and immunity-enhancing properties, such as echinacea, goldenseal and olive leaf, which you’ll find in either capsule or tincture form.
Medicinal Foods
For those who enjoy black beans, soybeans and lentils, MotherNature.com says a cup of beans provides 2,500 mg of lysine.
Prescription Medications
If you suffer from frequent occurrences of herpes simplex, you may want to talk to your doctor about a prescription for an antiviral medication. According to the University of Maryland Medical Center website, antiviral medications may speed healing and reduce recurring outbreaks by as much as 80 percent.
