Medications That Interact with Methotrexate: A Comprehensive Guide
Methotrexate is a widely used medication for treating various conditions, including rheumatoid arthritis, psoriasis, and certain types of cancer. However, like all medications, it can interact with other drugs, which may lead to adverse effects or reduce its efficacy. In this article, we will explore the medications that interact with methotrexate, highlighting the potential risks and consequences of these interactions.
What is Methotrexate?
Methotrexate, also known as MTX, is a chemotherapy agent and an immune system suppressant. It works by inhibiting the growth of rapidly dividing cells, such as cancer cells and immune cells. Methotrexate is available in various forms, including oral tablets, injections, and topical creams.
Common Medications That Interact with Methotrexate
1. Nonsteroidal Anti-Inflammatory Drugs (NSAIDs)
NSAIDs, such as ibuprofen (Advil, Motrin) and naproxen (Aleve), can increase the risk of bleeding and kidney damage when taken with methotrexate. This is because NSAIDs can reduce the blood's ability to clot and increase the risk of kidney damage.
2. Folic Acid Supplements
Folic acid supplements can reduce the effectiveness of methotrexate by increasing the levels of folate in the body. This can lead to reduced methotrexate levels and decreased treatment efficacy.
3. Penicillins and Sulfonamides
Penicillins, such as amoxicillin (Amoxil), and sulfonamides, such as sulfamethoxazole (Bactrim), can increase the risk of bleeding and kidney damage when taken with methotrexate.
4. Proton Pump Inhibitors (PPIs)
PPIs, such as omeprazole (Prilosec), can increase the levels of methotrexate in the body, leading to increased toxicity and side effects.
5. Live Vaccines
Live vaccines, such as the flu vaccine, can increase the risk of infection and disease when taken with methotrexate.
6. Blood Thinners
Blood thinners, such as warfarin (Coumadin), can increase the risk of bleeding when taken with methotrexate.
7. Cyclosporine
Cyclosporine, an immunosuppressant medication, can increase the levels of methotrexate in the body, leading to increased toxicity and side effects.
8. Other Interacting Medications
Other medications that interact with methotrexate include:
* Azathioprine (Imuran)
* Captopril (Capoten)
* Cimetidine (Tagamet)
* Ciprofloxacin (Cipro)
* Cyclophosphamide (Cytoxan)
* Doxorubicin (Adriamycin)
* Erythromycin (Erythrocin)
* Fluoxetine (Prozac)
* Hydroxychloroquine (Plaquenil)
* Leflunomide (Arava)
* Methysergide (Sansert)
* Phenytoin (Dilantin)
* Rifampin (Rifadin)
* Sulfasalazine (Azulfidine)
* Tetracyclines (e.g., doxycycline)
