Why clinicians prescribe it
Two ways to use it
Episodic at the first sign of an outbreak, or daily to prevent them.
Protects a partner
Daily suppressive dosing meaningfully lowers the chance of passing herpes on.
Works on cold sores too
The same antiviral treats oral herpes, not only genital.
Common questions
Daily suppression suits frequent outbreaks or anyone wanting to protect a partner. Episodic dosing suits occasional outbreaks. Your clinician will help you choose based on how often yours occur.
Important safety information
Tell your clinician about kidney problems, since the dose may need adjusting. Stay well hydrated. Uncommon side effects include headache and nausea. Seek care for confusion or a marked drop in urination.
