### Managing and Treating Cold Sores Caused by HSV Cold sores, also known as fever blisters or oral herpes, are caused by the herpes simplex virus (HSV). While there is no cure for HSV, there are several ways to manage and treat cold sores to reduce their duration and soothe symptoms. #### Antiviral Medications Doctors often prescribe antiviral medications to help cold sores heal faster. These can be taken orally or applied topically. Common antiviral medications include acyclovir, valacyclovir, and famciclovir. Over-the-counter treatments containing docosanol or benzyl alcohol can also help relieve symptoms. #### Natural Remedies Some natural remedies may offer relief and potentially reduce the duration of an outbreak. These include applying aloe vera, tea tree oil, or lemon balm to the affected area. However, it's best to consult your doctor before trying any home remedies. #### Sun Protection Exposure to the sun can trigger cold sores. Using a lip balm with sunscreen can help protect your lips and reduce the likelihood of future outbreaks. #### Hygiene Practices Good hygiene is crucial to prevent the spread of HSV. Wash your hands thoroughly with soap and water before touching your face or applying makeup. If you decide to wear makeup, use a single-use applicator to avoid spreading the virus. #### Avoiding Triggers Stress and sun exposure are common triggers for cold sores. Managing stress through relaxation techniques and protecting your lips from the sun can help reduce flare-ups. #### When to See a Doctor If a cold sore lasts more than 10 days, becomes infected, or spreads to your eyes, or if you develop a fever, it is important to visit your doctor for further evaluation and treatment. While cold sores usually heal on their own within 7 to 10 days, proper care can help reduce the duration of an outbreak and soothe symptoms.
