Your height and weight are the primary factors your healthcare provider will take into consideration when calculating the appropriate dose of pralatrexate (Folotyn®) for treating peripheral T-cell lymphoma. Using your height and weight helps your healthcare provider determine your body surface area, which is expressed as milligrams per meters squared (mg per m2). The usual recommended dosage of pralatrexate for treating peripheral T-cell lymphoma is 30 mg per m2.
This chemotherapy drug comes as a liquid that is injected into a vein (intravenous, or IV, injection). It is given by a healthcare provider once a week for six weeks, followed by a one-week break. You will need to take folic acid and vitamin B12 during treatment to help prevent certain pralatrexate side effects.
