Can acyclovir tablets cure herpes?

Acyclovir is clinically used—both topically and orally—to treat herpes zoster (shingles) and herpes simplex. For localized herpes simplex infections, topical acyclovir ointment may be applied, often in combination with oral acyclovir tablets. Can acyclovir tablets cure herpes definitively?

Can Acyclovir Tablets Cure Herpes Definitively?

Acyclovir is effective for treating both herpes simplex and herpes zoster. In primary herpes simplex infection, oral acyclovir tablets or intravenous acyclovir injection may be administered for a course of five to seven days. This regimen helps shorten the disease duration, alleviate patient discomfort, and reduce recurrence frequency—but it does not achieve a definitive cure. This is because the herpes simplex virus establishes latency within sensory nerve ganglia and can reactivate when the host’s immune defenses are compromised.

Acyclovir is also indicated for herpes zoster. Although recurrence is rare in herpes zoster, early antiviral therapy—including acyclovir—is strongly recommended within 72 hours of symptom onset. Acyclovir is indeed an effective antiviral agent for herpes infections and is widely used clinically for both herpes zoster and herpes simplex. It is available in both oral and topical formulations: oral acyclovir tablets and topical acyclovir ointment.

If herpes lesions are accompanied by erosion, adjunctive therapy with agents that promote epithelial healing—such as topical application of Kangfuxin Liquid—may be temporarily considered. We hope this information is helpful. Wishing you good health and happiness!
