It is very important to take folic acid tablets during your treatment with pralatrexate to lower your chances of harmful side effects. You must start taking 1 to 1.25 milligrams (mg) of folic acid every day for at least 10 days before your first dose. You must keep taking folic acid every day during therapy and for 30 days after your last pralatrexate dose. You can get folic acid as a nonprescription (over-the-counter [OTC]) product. Ask your doctor for help in choosing a folic acid product.
Your doctor will also give you vitamin B12 injections during your treatment with pralatrexate to lower your chances of harmful side effects. You will get your first injection about 10 weeks before your first dose, and additional injections about every 8 to 10 weeks during therapy.
