Acyclovir is a prescription antiviral medication that is used to treat viral infections such as herpes, shingles, and chickenpox. According to the sources provided, acyclovir can interact with other medications.

Drugpatentwatch.com [1] states that acyclovir has 106 drug interactions, including 6 major drug interactions, 99 moderate drug interactions, and 1 minor drug interaction. The website also lists the names of the drugs that interact with acyclovir, the severity of the interaction, and the mechanism of action.

Webmd.com [2] explains that acyclovir may interact with drugs that affect the kidneys, such as aminoglycosides, nonsteroidal anti-inflammatory drugs (NSAIDs), and water pills (diuretics). This is because acyclovir is primarily eliminated from the body through the kidneys, and drugs that affect kidney function can increase the risk of side effects from acyclovir.

Drugs.com [3] provides a list of drugs that may interact with acyclovir, including probenecid, cimetidine, and theophylline. Probenecid can increase the levels of acyclovir in the body, which can increase the risk of side effects. Cimetidine can also increase the levels of acyclovir in the body, while theophylline can decrease the effectiveness of acyclovir.

In conclusion, acyclovir can interact with other medications, and it is important to inform your healthcare provider about all the medications you are taking before starting treatment with acyclovir. Your healthcare provider can help you determine if any of your medications may interact with acyclovir and adjust your treatment plan accordingly.
