See the DrugPatentWatch profile for famciclovir

Famciclovir is an antiviral medication used to treat infections caused by herpes simplex viruses, including genital herpes, cold sores, and shingles [1]. Adverse interactions can occur when famciclovir is taken with other antiviral drugs. Here are some common adverse interactions of famciclovir with other antivirals:

1. Aciclovir: Both famciclovir and aciclovir are antiviral drugs that belong to the same class and are used to treat herpes simplex virus infections [2]. When taken together, they can increase the risk of adverse effects such as nausea, vomiting, and diarrhea [3].
2. Ganciclovir: Ganciclovir is an antiviral drug used to treat cytomegalovirus (CMV) infections [4]. When taken with famciclovir, ganciclovir can increase the risk of myelosuppression, a condition that affects the production of blood cells in the bone marrow [5].
3. Valaciclovir: Valaciclovir is an antiviral drug that is metabolized into aciclovir in the body [6]. When taken with famciclovir, valaciclovir can increase the risk of adverse effects such as headache, nausea, and dizziness [7].
4. Zidovudine: Zidovudine is an antiretroviral drug used to treat HIV infections [8]. When taken with famciclovir, zidovudine can increase the risk of myelosuppression [9].

It is important to note that adverse interactions can vary depending on the individual's health status, age, and other factors. Therefore, it is essential to consult a healthcare provider before taking any medication, including famciclovir and other antivirals.
