Methotrexate is a widely used medication primarily prescribed for the treatment of various types of cancer, including leukemia, lymphoma, and solid tumors. It is also used to manage certain inflammatory conditions such as rheumatoid arthritis, psoriasis, and psoriatic arthritis. Methotrexate belongs to the class of drugs known as antimetabolites, which work by inhibiting the growth of cancer cells and reducing inflammation.
There are several contraindications to taking methotrexate that should be considered before initiating treatment. It should not be used in individuals with a history of hypersensitivity to the drug or any of its components. Methotrexate is contraindicated in pregnant women and individuals with severe liver or kidney disease. It should not be taken by individuals with a weakened immune system or those currently receiving radiation therapy or undergoing bone marrow transplantation. Additionally, methotrexate should not be administered to breastfeeding women due to potential harm to the nursing infants.
Like any medication, methotrexate may cause certain side effects, which may vary depending on the specific condition being treated. Common side effects include nausea, vomiting, diarrhea, mouth sores, and dizziness. Methotrexate can also lead to a temporary decrease in blood cell counts, which can increase the risk of infection and bleeding. It is important to promptly report any signs of infection, including fever and sore throat, to the healthcare provider. In some cases, methotrexate can cause more serious side effects, such as liver toxicity or lung problems. Regular monitoring of liver function and lung function is necessary to minimize these risks.
Methotrexate is usually taken once weekly or as directed by the healthcare provider. It can be taken orally or given by injection, depending on the specific condition being treated. The dosage and duration of treatment will be determined by the healthcare provider based on the individual’s response and medical history. It is important to follow the prescribed regimen and never exceed the recommended dose. If a dose is missed, it should be taken as soon as remembered unless it is close to the next scheduled dose. In cases of overdose, immediate medical attention should be sought, as it can lead to serious complications.
Methotrexate can interact with several medications, potentially leading to adverse effects or reduced efficacy. Nonsteroidal anti-inflammatory drugs (NSAIDs), such as aspirin or ibuprofen, should be used with caution as they can increase the risk of methotrexate toxicity. Certain antibiotics, such as trimethoprim/sulfamethoxazole, may also interact with methotrexate and should be avoided if possible. It is important to inform the healthcare provider about all medications, including prescription, over-the-counter, and herbal supplements, being taken concurrently with methotrexate to minimize the risk of drug interactions.
