Understanding Methotrexate Interactions: A Comprehensive Guide

Methotrexate is a widely used medication for treating various conditions, including rheumatoid arthritis, psoriasis, and certain types of cancer. While it can be an effective treatment option, it's essential to understand the potential interactions between methotrexate and other prescribed drugs. In this article, we'll delve into the world of methotrexate interactions, exploring the risks, consequences, and precautions to take.

The Importance of Monitoring Interactions

Methotrexate is a powerful medication that can interact with other drugs, increasing the risk of adverse effects. According to the American College of Rheumatology, methotrexate interactions can lead to serious complications, including liver damage, bone marrow suppression, and increased risk of infections (1).

Common Medications that Interact with Methotrexate

Several medications can interact with methotrexate, including:

* Nonsteroidal anti-inflammatory drugs (NSAIDs): NSAIDs, such as ibuprofen and naproxen, can increase the risk of kidney damage and bleeding when taken with methotrexate (2).
* Antibiotics: Certain antibiotics, like trimethoprim-sulfamethoxazole, can increase the risk of methotrexate toxicity (3).
* Blood thinners: Medications like warfarin can increase the risk of bleeding when taken with methotrexate (4).
* Cancer chemotherapy agents: Chemotherapy agents, such as cyclophosphamide, can increase the risk of methotrexate toxicity (5).
