Medications That Interact with Acyclovir: A Comprehensive Guide
Acyclovir is a widely used antiviral medication prescribed to treat various viral infections, including herpes simplex virus (HSV), varicella-zoster virus (VZV), and cytomegalovirus (CMV). While acyclovir is generally safe and effective, it can interact with other medications, which may lead to adverse effects or reduce its efficacy. In this article, we will explore the medications that interact with acyclovir, highlighting the potential risks and consequences of these interactions.
What Are Medication Interactions?
Medication interactions occur when two or more medications interact with each other, either by enhancing or reducing their effects, or by causing adverse reactions. These interactions can be classified into several types, including:
* Pharmacokinetic interactions: These occur when one medication affects the absorption, distribution, metabolism, or excretion of another medication.
* Pharmacodynamic interactions: These occur when one medication affects the mechanism of action of another medication.
Medications That Interact with Acyclovir
Several medications can interact with acyclovir, including:
1. Probenecid
Probenecid is a medication used to treat gout and high blood pressure. It can increase the levels of acyclovir in the body by reducing its excretion, leading to increased risk of side effects.
