It's important to follow your doctor's prescribed regimen for antiviral medication. Taking the medication as directed can help manage herpes outbreaks and reduce transmission risk. Skipping doses or only taking them during outbreaks may not provide sufficient protection against the virus.

Consistent use of antivirals helps suppress viral activity in your body, reducing outbreak frequency and severity. It is unlikely that intermittent dosing would lead to immunity build-up, but it may decrease the effectiveness of the treatment over time.

To ensure optimal results, it's best to adhere to your doctor’s guidance on dosage and timing of antiviral medications consistently. If you have concerns about side effects or treatment efficacy, discuss them with your healthcare provider before making any changes.
