The Potential Side Effects of Methotrexate: Understanding the Risks
Methotrexate is a widely used medication for the treatment of various conditions, including rheumatoid arthritis, psoriasis, and certain types of cancer. While it has been shown to be effective in managing symptoms and slowing disease progression, methotrexate can also cause a range of potential side effects. In this article, we will delve into the possible side effects of methotrexate, their severity, and what you can do to minimize them.
What is Methotrexate?
Methotrexate is a chemotherapy medication that belongs to a class of drugs called antimetabolites. It works by inhibiting the growth of rapidly dividing cells, such as cancer cells and immune cells involved in autoimmune diseases. Methotrexate is available in various forms, including oral tablets, injections, and topical creams.

According to the National Institutes of Health (NIH), common side effects of methotrexate include:
* Nausea and vomiting: These symptoms are often mild and temporary, but can be severe in some cases.

* Headaches: Mild to moderate headaches are a common side effect of methotrexate.
* Dizziness: Some people may experience dizziness or lightheadedness when taking methotrexate.
* Diarrhea: Methotrexate can cause changes in bowel movements, leading to diarrhea or constipation.
Less Common but Serious Side Effects of Methotrexate
While rare, methotrexate can cause more serious side effects, including:
* Liver damage: Methotrexate can cause liver inflammation and damage, which can be reversible with treatment.
* Bone marrow suppression: Methotrexate can affect the production of blood cells, leading to anemia, low white blood cell count, and low platelet count.
* Increased risk of infections: Methotrexate can weaken the immune system, making you more susceptible to infections.
* Respiratory problems: Methotrexate can cause lung damage and increase the risk of respiratory infections.
Long-Term Side Effects of Methotrexate
Long-term use of methotrexate can lead to:
* Liver fibrosis: Scarring of the liver tissue, which can be irreversible.
* Bone marrow failure: Permanent damage to the bone marrow, leading to anemia and other blood-related disorders.
* Increased risk of cancer: Long-term use of methotrexate has been linked to an increased risk of certain types of cancer, including leukemia and lymphoma.
Preventing and Managing Side Effects of Methotrexate
To minimize the risk of side effects, it's essential to:
* Take methotrexate as directed: Follow your doctor's instructions for dosage and administration.
* Monitor your liver function: Regular blood tests can help detect liver damage early.
* Get regular blood counts: Monitor your blood cell counts to prevent bone marrow suppression.
* Stay hydrated: Drink plenty of water to prevent dehydration and constipation.
* Eat a balanced diet: A healthy diet can help reduce the risk of side effects.
Expert Insights
According to Dr. Eric Matteson, a rheumatologist at the Mayo Clinic, "Methotrexate is a powerful medication that can have significant side effects. However, with proper monitoring and management, the benefits of methotrexate can outweigh the risks for many patients."
