Cold Sore – HSV

Cold sores, also called fever blisters or oral herpes, are commonly caused by the herpes simplex virus. Prescription oral antiviral medications such as valacyclovir or acyclovir may help manage an outbreak and shorten its duration when clinically appropriate. Treatment is generally most effective when started at the first sign of symptoms, such as tingling, itching, burning, or blister formation.

This option includes an urgent-care provider evaluation for patients experiencing a suspected cold sore outbreak. A licensed provider reviews your symptoms, medical history, allergies, current medications, kidney health, and questionnaire responses to determine whether antiviral treatment may be appropriate.

If approved, the provider may prescribe oral valacyclovir or acyclovir based on your individual needs. The medication, dosage, and treatment duration are selected by the provider in accordance with applicable clinical guidelines. Follow the instructions included with your prescription carefully.

Completing an evaluation or purchasing this service does not guarantee that medication will be prescribed. Treatment is subject to provider discretion, pharmacy requirements, state regulations, and medication availability.

Antiviral medication can help manage an outbreak but does not cure herpes simplex infection or completely prevent transmission. Avoid kissing, oral contact, and sharing personal items while a cold sore is present. Seek prompt in-person care for sores near the eye, eye pain or redness, a widespread or unusually severe outbreak, difficulty eating or drinking, or symptoms occurring with a weakened immune system.
