Famciclovir is an antiviral medication used to treat infections caused by herpes viruses, including genital herpes, cold sores, and shingles [1]. Like many medications, famciclovir can interact negatively with other drugs, potentially leading to reduced effectiveness or increased side effects.

According to Drugs.com, probenecid, a medication used to treat gout and kidney stones, can increase the levels of famciclovir in the body, potentially leading to increased side effects [2]. Therefore, it is recommended to avoid taking probenecid and famciclovir together.

Another source, DrugPatentWatch.com, does not provide specific information on negative interactions between famciclovir and other drugs [3]. However, it is always important to consult with a healthcare provider or pharmacist before starting any new medication, including famciclovir, to ensure that it is safe to take with any other medications being currently used.

In summary, probenecid is a medication that can negatively interact with famciclovir, potentially leading to increased side effects. It is important to consult with a healthcare provider or pharmacist before starting any new medication, including famciclovir, to ensure that it is safe to take with any other medications being currently used.
