Biotrexate 500mg

The dosage of Methotrexate in Biotrexate 500mg is higher than the usual recommended dosage for most indications. Methotrexate is typically used in lower doses (e.g., 2.5mg to 30mg) for the treatment of rheumatoid arthritis, psoriatic arthritis, and polyarticular juvenile idiopathic arthritis.

Using a higher dose of Methotrexate, such as 500mg, may increase the risk of severe side effects, particularly those related to the gastrointestinal and hematopoietic systems.
