Buying Guide
What should I look for in an over-the-counter fever blister medicine?
Key factors include the active ingredient (docosanol 10% is common and evidence suggests faster healing when used early), delivery format (cream, gel, or pump), and the number of applications per day. Choose a product that matches your typical outbreak frequency and your preference for portability or multi-pack availability.
When is docosanol the best option?
Docosanol 10% is widely recommended for early symptoms such as tingling or itching. It works by inhibiting viral entry into healthy cells, potentially shortening healing time when applied promptly after symptoms begin.
Is a numbing agent worth it?
Gel or kit formulations with lidocaine or camphor offer immediate pain relief, which can improve comfort during outbreaks. These should be used in addition to antiviral ingredients if needed, not as a sole treatment for the virus.
Which packaging format works best for you?
Single-tube formats are compact and budget-friendly. Multi-pack options are convenient for households with multiple users or frequent outbreaks. Pumps offer easier, mess-free application on the go.
