Is Methotrexate's Efficacy Compromised by Common OTC Drugs?

Methotrexate is a powerful medication used to treat various conditions, including rheumatoid arthritis, psoriasis, and breast cancer. As a potent immunosuppressant, it can be effective in reducing inflammation and slowing down the progression of these diseases. However, its efficacy can be compromised by various factors, including interactions with over-the-counter (OTC) drugs.

What are OTC Drugs?

Before we dive into the potential interactions between methotrexate and OTC drugs, let's define what OTC drugs are. OTC drugs are medications that can be purchased without a prescription from a healthcare provider. They are often used to treat minor ailments, such as headaches, colds, and allergies.

Common OTC Drugs that May Interact with Methotrexate

While methotrexate is a powerful medication, it can interact with various OTC drugs, including:

Pain Relievers

* Acetaminophen (Tylenol): Taking acetaminophen with methotrexate can increase the risk of liver damage.
* Ibuprofen (Advil, Motrin): Ibuprofen can increase the risk of bleeding and kidney damage when taken with methotrexate.

Antihistamines

* Diphenhydramine (Benadryl): Diphenhydramine can increase the risk of drowsiness and confusion when taken with methotrexate.
* Loratadine (Claritin): Loratadine can increase the risk of liver damage when taken with methotrexate.

Antacids

* Tums: Taking antacids like Tums with methotrexate can reduce its absorption and effectiveness.
* Ranitidine (Zantac): Ranitidine can increase the risk of stomach upset and diarrhea when taken with methotrexate.

Cold and Cough Medications

* Decongestants (Pseudoephedrine, Phenylephrine): Decongestants can increase blood pressure and heart rate when taken with methotrexate.
* Cough suppressants (Dextromethorphan): Cough suppressants can increase the risk of drowsiness and confusion when taken with methotrexate.
