Bidwell Health clinical notes
Can I Spread Herpes While Taking Valacyclovir?
Yes, herpes can still spread while taking valacyclovir. Daily suppressive therapy can reduce risk for some patients, especially symptomatic genital HSV-2 patients, but risk is not zero and medication does not replace avoiding sex during outbreaks.
What does daily medication actually do?
Suppressive antiviral therapy can reduce outbreak frequency and may reduce transmission risk. CDC guidance describes daily valacyclovir reducing HSV-2 transmission in discordant heterosexual couples where one partner has symptomatic genital HSV-2. That is risk reduction, not a guarantee.
When is someone more likely to transmit herpes?
Transmission risk is higher when sores, ulcers, or prodrome symptoms are present. Prodrome can include tingling, burning, itching, pain, or skin sensitivity before sores appear. Avoid sex or direct skin contact with the affected area during those periods.
What about condoms?
Condoms can reduce HSV-2 transmission risk when used consistently and correctly, but they do not eliminate risk because herpes can shed from skin not covered by a condom. Medication, condoms, and avoiding sex during symptoms work together; none is perfect alone.
What if I have oral herpes?
Cold sores can spread through kissing or oral contact, especially when a sore or warning symptoms are present. Avoid kissing, oral sex, and sharing lip products during an active cold sore or prodrome.
How does Bidwell frame suppressive therapy?
Bidwell treats daily therapy as a clinical decision, not a promise. The clinician reviews prior diagnosis, outbreak frequency, partner concerns, kidney history, pregnancy status, medication tolerance, and whether a 90-day suppressive cycle is appropriate.

What to do if you are unsure
- If this is truly your first outbreak (new diagnosis), prioritize in-person testing and STI screening as appropriate.
- If you already have a confirmed diagnosis and symptoms match prior outbreaks, online outbreak treatment or suppressive therapy may be reasonable.
Questions to bring to a clinician
- Is lesion swab testing available (PCR) if sores are present?
- Do I need other STI testing?
- Is suppressive therapy appropriate given my recurrence frequency and partner risk?
