The typical prescription for acyclovir to treat shingles involves taking 800 milligrams five times a day. This regimen usually continues for seven to ten days. Your doctor will determine the precise duration based on your individual health status and the severity of your shingles.
Timing and Administration
Consistency is key. Space your doses evenly throughout the day. Taking acyclovir with food can minimize potential stomach upset. Always follow your physician’s instructions carefully regarding dosage and timing. Missing doses can reduce the medication’s effectiveness.
Potential Side Effects
While generally well-tolerated, acyclovir can cause side effects such as nausea, headache, and diarrhea. More serious, though rare, reactions may include kidney problems. Report any unusual symptoms to your doctor immediately. They can adjust your treatment plan as necessary.
Alternative Dosages
Note: Adjustments to the 800mg five-times-daily dosage are possible depending on factors like kidney function. Your doctor might prescribe a lower dose, especially for individuals with impaired kidney function. Never alter your prescribed dosage without consulting your healthcare provider.
Important Considerations
Acyclovir is most effective when started within 72 hours of the onset of shingles symptoms. Early treatment significantly reduces the duration and severity of the rash and associated pain. This medication treats the virus, but doesn’t eliminate the risk of postherpetic neuralgia (PHN), a long-lasting nerve pain after shingles. Your doctor may discuss PHN preventative measures alongside your acyclovir treatment.
