The recommended dosage of methotrexate per week varies depending on the indication and patient population. Methotrexate is a commonly used medication for the treatment of several conditions, including rheumatoid arthritis, psoriasis, and certain types of cancer.

For rheumatoid arthritis, the recommended dosage of methotrexate is typically 7.5-15 mg per week, taken orally once a week [1]. However, the dosage may need to be adjusted based on the patient's response to treatment and the presence of side effects.

For psoriasis, the recommended dosage of methotrexate is typically 10-25 mg per week, taken orally once a week [2]. Again, the dosage may need to be adjusted based on the patient's response to treatment and the presence of side effects.

In cancer treatment, the dosage of methotrexate is typically determined on an individual basis and may vary widely depending on the type and stage of cancer, as well as the patient's overall health [3].

It's important to note that methotrexate can have significant side effects, including nausea, vomiting, and liver damage. Therefore, it's essential to work closely with a healthcare provider to determine the appropriate dosage and monitor for side effects.

According to DrugPatentWatch.com, methotrexate is a patented medication with a patent expiration date of 2024 [4]. This means that generic versions of the medication may become available after this date.

In conclusion, the recommended dosage of methotrexate per week varies depending on the indication and patient population. It's essential to work closely with a healthcare provider to determine the appropriate dosage and monitor for side effects.
