Methotrexate is a widely used prescription medicine that has stood the test of time in treating both cancer and chronic inflammatory disorders. It belongs to a class of drugs called antimetabolites, which work by interfering with folate metabolism — an essential process for producing DNA and RNA in rapidly dividing cells. This mechanism makes methotrexate effective in slowing the growth of cancer cells and dampening abnormal immune responses in autoimmune conditions. It’s available in tablet and injectable forms, and the specific dose depends on the condition being treated.

Primary Uses:

  • Rheumatoid arthritis & Psoriasis: Low-dose weekly methotrexate is a cornerstone therapy for reducing inflammation, easing pain, and slowing disease progression.
  • Autoimmune conditions: It’s also used in psoriatic arthritis and juvenile idiopathic arthritis when other treatments have not worked.
  • Cancer therapy: At higher doses, methotrexate is part of chemotherapy regimens for leukemia and certain solid tumors, where it helps slow malignant cell growth.

Side Effects 

While methotrexate provides significant therapeutic benefit, it can also cause side effects ranging from mild to serious. Common reactions include nausea, loss of appetite, stomach discomfort, mouth sores, and fatigue. Because it impacts rapidly dividing cells, methotrexate can also affect the bone marrow, liver, lungs, and immune system. This may lead to liver toxicity, breathing difficulties, increased risk of infections, and blood-cell count abnormalities. For this reason, patients are routinely monitored with blood tests throughout their treatment. Methotrexate can also be dangerous in pregnancy, so effective contraception is recommended during and after therapy.

During certain medical treatments or health conditions, the body undergoes visible changes, particularly in the skin.

In cancer patients, especially, the skin may become dry, itchy, or even fragile, requiring special care and hydration.

A compromised immune system is another concern, especially during cancer treatment. White blood cells, which play a vital role in fighting infection, often decrease significantly during chemotherapy, leaving the patient vulnerable. To protect against potential infections, patients are advised to wear protective clothing, avoid crowded places, and maintain proper hygiene. These preventive steps help reduce the chances of infections and complications while the immune system is suppressed.

Patients may also experience several common side effects, including swelling of the skin or eyes, fatigue, and loss of appetite. These symptoms can vary in severity based on the individual and the treatment regimen. Swelling may be a sign of an allergic reaction or fluid retention, both of which require medical attention.

FAQs

What is methotrexate and how does it work?

Methotrexate is a prescription medication that acts as a chemotherapy agent and immunosuppressant. It works by interfering with the body’s use of folate — a vitamin crucial for DNA and RNA synthesis — which slows the growth of rapidly dividing cells such as cancer cells and calms the overactive immune response seen in autoimmune diseases like rheumatoid arthritis and psoriasis.

What conditions is methotrexate used to treat?

Methotrexate has a broad range of uses. At low, weekly doses it is commonly prescribed for autoimmune and inflammatory conditions such as rheumatoid arthritis, psoriasis, and juvenile idiopathic arthritis. At higher doses, especially under specialist supervision, it’s part of chemotherapy regimens for various cancers including leukemia, breast cancer, lung cancer, and certain lymphomas.

What are common side effects of methotrexate?

Common side effects include nausea, fatigue, mouth sores, headaches, and hair thinning, which often improve as the body adjusts. Because methotrexate can also affect organs like the liver and lungs and lower blood cell counts, regular monitoring through blood tests is essential to catch any serious issues early.

Are there serious risks I should know about?

Yes. In addition to mild effects, methotrexate can rarely cause liver toxicity, lung problems, severe allergic reactions, and suppression of bone marrow, which increases infection risk. It is also not safe in pregnancy due to the risk of birth defects, so effective contraception is recommended during and after treatment.

How is methotrexate taken and monitored?

For autoimmune diseases, methotrexate is usually taken once a week (not daily) in tablet or injection form as prescribed by a doctor. Regular lab tests — including liver function, kidney function, and complete blood counts — are required to ensure safety and adjust dosing. Many doctors also recommend folic acid supplements to help reduce common side effects.
