OTC Medications to Avoid with Methotrexate: A Comprehensive Guide

Methotrexate is a powerful medication used to treat various conditions, including rheumatoid arthritis, psoriasis, and certain types of cancer. While it can be an effective treatment option, it's essential to be aware of the potential interactions with over-the-counter (OTC) medications. In this article, we'll explore the OTC medications to avoid with methotrexate and provide guidance on how to safely use these medications.

Understanding Methotrexate and Its Interactions

Methotrexate is a folate antagonist that works by inhibiting the production of certain enzymes in the body. This can lead to a range of side effects, including nausea, vomiting, and fatigue. When taken with other medications, methotrexate can increase the risk of adverse reactions, including liver damage, bone marrow suppression, and increased risk of infections.

OTC Medications to Avoid with Methotrexate

While methotrexate can be safely taken with some OTC medications, there are several that should be avoided or used with caution. Here are some of the most common OTC medications to avoid with methotrexate:

*

Nonsteroidal Anti-Inflammatory Drugs (NSAIDs)

NSAIDs, such as ibuprofen (Advil, Motrin) and naproxen (Aleve), can increase the risk of stomach ulcers and bleeding when taken with methotrexate. According to the American College of Rheumatology, NSAIDs should be avoided in patients taking methotrexate unless absolutely necessary. [1]
*

Acetaminophen (Tylenol)

While acetaminophen is generally considered safe to take with methotrexate, high doses can increase the risk of liver damage. The FDA recommends limiting acetaminophen doses to 2,000 mg per day when taken with methotrexate. [2]
*

Aspirin

Aspirin can increase the risk of bleeding and stomach ulcers when taken with methotrexate. According to the National Psoriasis Foundation, aspirin should be avoided in patients taking methotrexate unless absolutely necessary. [3]
*

Antihistamines

Antihistamines, such as diphenhydramine (Benadryl), can increase the risk of drowsiness and dizziness when taken with methotrexate. According to the Mayo Clinic, antihistamines should be used with caution in patients taking methotrexate. [4]
*

Decongestants

Decongestants, such as pseudoephedrine (Sudafed), can increase the risk of high blood pressure and heart palpitations when taken with methotrexate. According to the American Heart Association, decongestants should be used with caution in patients taking methotrexate. [5]

OTC Medications That Are Generally Safe to Take with Methotrexate

While it's essential to avoid certain OTC medications with methotrexate, there are several that are generally considered safe to take. Here are some examples:

*

Antacids

Antacids, such as Tums and Rolaids, can help alleviate stomach upset and heartburn when taken with methotrexate. According to the American Gastroenterological Association, antacids are generally safe to take with methotrexate. [6]
*

Laxatives

Laxatives, such as senna (Ex-Lax) and bisacodyl (Dulcolax), can help alleviate constipation when taken with methotrexate. According to the American College of Gastroenterology, laxatives are generally safe to take with methotrexate. [7]

While methotrexate can be safely taken with some OTC medications, it's essential to follow certain precautions and warnings:
