Acyclovir is an antiviral medication used to treat herpes infections, including genital herpes, shingles, and chickenpox. According to the sources provided, there is no maximum daily intake of acyclovir. However, the dosage of acyclovir varies depending on the condition being treated and the patient's age, weight, and kidney function.

The recommended dose of acyclovir for adults with genital herpes is 200mg five times daily for 10 days [2]. For shingles, the recommended dose is 800mg five times daily for 7-10 days [2]. The dose of acyclovir for children with chickenpox is based on their weight, with a maximum daily dose of 800mg [3].

It is important to note that acyclovir is primarily eliminated by the kidneys, and patients with impaired renal function may require a lower dose or less frequent dosing to avoid toxicity [2]. Patients should always follow their healthcare provider's instructions for taking acyclovir and report any side effects or concerns.

In summary, while there is no maximum daily intake of acyclovir, the dosage of acyclovir varies depending on the condition being treated and the patient's age, weight, and kidney function. Patients should always follow their healthcare provider's instructions for taking acyclovir and report any side effects or concerns.
