I appreciate you thinking proactively about this. Here's what matters: **stopping and restarting acyclovir doesn't work like "resetting" potency.** The medication works while you're taking it consistently—it suppresses viral shedding and reduces outbreak risk. When you stop, that protection begins declining relatively quickly; when you restart, it takes a few days to re-establish suppression, not a full week.

A one-week break followed by one week back on won't give you "full efficacy" by the end. More importantly, **skipping doses increases asymptomatic shedding risk during that gap and the restart period**, which matters if transmission prevention is your concern.

**Better approach:** Talk with your prescriber about your situation. They may suggest:
- Continuing daily dosing through the separation (simplest, most protective)
- Adjusting timing if that's the actual barrier
- Discussing your specific transmission concerns, which they can address with current evidence

Acyclovir is safe for long-term daily use, so there's no medical reason to take a break. Your provider can give you personalized guidance based on your full picture.

**Bottom line:** Don't engineer a medication gap hoping for a timing advantage—it doesn't work that way and creates unnecessary risk. A quick conversation with your doctor will clarify what actually serves you both best.
