Elderly individuals who are using methotrexate should be aware of certain considerations to ensure safe and effective use of the medication. Methotrexate is a commonly prescribed drug for various conditions, including rheumatoid arthritis, psoriasis, and certain types of cancer. However, its use in elderly patients requires careful monitoring and adjustments to minimize potential risks and maximize benefits.

Firstly, it is important to note that elderly individuals may have age-related changes in their metabolism and organ function, which can affect the way their bodies process and eliminate medications like methotrexate [2]. This can potentially increase the risk of side effects and toxicity. Therefore, close monitoring of kidney and liver function is crucial in elderly patients using methotrexate [2].

Secondly, methotrexate can have adverse effects on the blood, including decreased production of blood cells. In elderly patients, who may already have age-related changes in their blood cell production, this can pose an additional risk [2]. Regular blood tests should be conducted to monitor blood cell counts and ensure that they remain within the acceptable range.

Furthermore, elderly individuals are more likely to have multiple chronic conditions and take multiple medications simultaneously, which increases the risk of drug interactions. Methotrexate can interact with certain medications, such as nonsteroidal anti-inflammatory drugs (NSAIDs), proton pump inhibitors (PPIs), and sulfonamides [1]. It is essential for healthcare providers to review the elderly patient's complete medication list and evaluate potential interactions before prescribing methotrexate.

Lastly, elderly patients may also be more susceptible to certain side effects of methotrexate, such as gastrointestinal disturbances, liver toxicity, and lung problems [2]. Therefore, it is important for healthcare providers to start with a lower dose and gradually increase it as tolerated, while closely monitoring for any adverse effects.

In summary, elderly individuals using methotrexate should be closely monitored for potential age-related changes in metabolism and organ function, as well as blood cell counts. Regular blood tests, careful evaluation of drug interactions, and starting with a lower dose are important considerations to ensure the safe and effective use of methotrexate in this population.
