When you hear methotrexate, a drug used to treat autoimmune conditions and some cancers by slowing down overactive cells. Also known as MTX, it's one of the most prescribed medications for rheumatoid arthritis, psoriasis, and certain types of lymphoma. It’s not a miracle cure, but for millions, it’s the difference between constant pain and being able to get out of bed.
Methotrexate doesn’t just kill cells—it calms them. In autoimmune diseases like rheumatoid arthritis, your immune system attacks your own joints. Methotrexate steps in as a brake, reducing inflammation and slowing joint damage. In cancer, it targets fast-growing cells, which is why it’s used for leukemia and lymphoma. But here’s the catch: it doesn’t know the difference between a cancer cell and a healthy one. That’s why side effects like fatigue, nausea, and lowered blood counts happen. It’s a powerful tool, but it needs careful handling.
People often mix up methotrexate with other chemo drugs, but it’s different. Unlike some that are given intravenously in hospitals, methotrexate can be taken as a pill or shot at home. It’s also used in lower doses for autoimmune conditions than for cancer. And while it’s not the first choice for everyone, it’s often the most cost-effective and well-studied option. If side effects become too much, doctors may switch to alternatives like sulfasalazine, hydroxychloroquine, or newer biologics like adalimumab. But for many, methotrexate remains the backbone of treatment.
You’ll find posts here that compare methotrexate to other drugs used in similar conditions—like how it stacks up against biologics for psoriasis, or how hydration and folic acid can reduce its side effects. Some articles look at what happens when methotrexate stops working, or how it interacts with common painkillers. Others explore why some people tolerate it for years while others can’t even finish the first month. There’s no one-size-fits-all answer, but the real stories and data here can help you understand where you stand.
