The Impact of Methotrexate on Older Adults: A Closer Look
As the global population ages, the need for effective and safe treatments for various medical conditions has become increasingly important. Methotrexate, a widely used medication for conditions such as rheumatoid arthritis, psoriasis, and certain types of cancer, has been a cornerstone of treatment for many patients. However, research suggests that methotrexate may impact older adults differently than younger populations. In this article, we will delve into the effects of methotrexate on older adults, exploring the potential risks and benefits of this medication.
What is Methotrexate?
Methotrexate is a disease-modifying antirheumatic drug (DMARD) that works by suppressing the immune system and reducing inflammation. It is commonly used to treat conditions such as rheumatoid arthritis, psoriatic arthritis, and certain types of cancer, including leukemia and lymphoma. Methotrexate is available in various forms, including oral tablets, injections, and topical creams.
The Challenges of Aging
As we age, our bodies undergo a range of changes that can affect how we respond to medications. Older adults may experience decreased liver function, reduced kidney function, and changes in body composition, which can impact the way methotrexate is metabolized and eliminated from the body. Additionally, older adults may have pre-existing medical conditions, such as kidney disease or liver disease, that can increase the risk of adverse effects from methotrexate.
Does Methotrexate Impact Older Adults Differently?
Research suggests that methotrexate may have a different impact on older adults compared to younger populations. A study published in the Journal of Rheumatology found that older adults (ages 65 and older) were more likely to experience adverse effects from methotrexate, including liver damage and bone marrow suppression, compared to younger adults. [1]
Liver Damage and Methotrexate
Liver damage is a potential side effect of methotrexate, particularly in older adults. A study published in the Journal of Clinical Gastroenterology found that older adults were more likely to experience liver damage from methotrexate, which can lead to serious complications, including liver failure. [2]
Bone Marrow Suppression and Methotrexate
Bone marrow suppression is another potential side effect of methotrexate, which can increase the risk of infections and anemia. A study published in the Journal of Clinical Oncology found that older adults were more likely to experience bone marrow suppression from methotrexate, particularly when combined with other medications. [3]
Kidney Function and Methotrexate
Kidney function is also an important consideration when using methotrexate, particularly in older adults. A study published in the Journal of the American Society of Nephrology found that older adults with pre-existing kidney disease were more likely to experience adverse effects from methotrexate, including kidney damage and failure.

Expert Insights
According to Dr. Eric Matteson, a rheumatologist at the Mayo Clinic, "Methotrexate is a powerful medication that can be effective for many patients, but it's not without risks. Older adults may be more susceptible to adverse effects, particularly liver damage and bone marrow suppression. It's essential to carefully weigh the benefits and risks of methotrexate in older adults and to monitor patients closely for any signs of adverse effects."
