Does Daily Valtrex Lower Herpes Transmission Risk?

Daily antiviral therapy can reduce herpes transmission risk for some patients, but it does not make the risk zero. Bidwell discusses suppressive therapy as one part of risk reduction, alongside avoiding sex during outbreaks, condoms, and partner communication.

Prior diagnosis required. Bidwell treats adults ages 18-64 who have already been diagnosed with oral or genital herpes by a healthcare provider. Bidwell does not diagnose new herpes infections online, does not require photo upload, and does not guarantee treatment.

What daily antivirals can and cannot do

Suppressive therapy can reduce outbreak frequency and may reduce transmission risk. It does not cure herpes, does not eliminate shedding, and does not replace avoiding sexual contact during outbreaks or prodrome symptoms.

Why this question matters

Many patients ask about suppressive therapy because they are dating, starting a new relationship, or trying to reduce partner risk. The correct answer needs to be honest: lower risk is not zero risk.

What does Bidwell review?

The clinician reviews prior diagnosis, outbreak frequency, treatment goals, medication history, kidney history, pregnancy status, immune-system risk, and whether daily therapy is reasonable in a 90-day cycle.

When daily therapy may not fit

Daily therapy may not be worth it for very rare outbreaks, uncertain diagnosis, side effects, kidney disease requiring individualized dosing, or patients who prefer episodic treatment.
