Why is this medication prescribed?
After receiving treatment with various drugs, peripheral T-cell lymphoma (PTCL; a type of cancer that starts in specific immune system cells) that has not improved or returned is treated with pralatrexate injection. There is no evidence that pralatrexate injection prolongs the lives of lymphoma patients. The drug pralatrexate injection belongs to the group of drugs known as folate analogue metabolic inhibitors. It eliminates cancer cells to work.
How should this medicine be used?
In a hospital or clinic, a doctor or nurse will administer pralatrexate injection as an intravenous (into a vein) solution. It is typically administered once a week for 6 weeks throughout a 7-week cycle, lasting 3 to 5 minutes total. The likelihood is that you will receive therapy until your condition deteriorates or you experience major side effects.
If you have certain adverse effects, your doctor may need to change your dose, skip a dose, or stop your therapy. During your pralatrexate injection therapy, be sure to let your doctor know how you are feeling.
To assist prevent some adverse effects, you must take folic acid and vitamin B12 while receiving treatment with pralatrexate injection. Your doctor would probably advise you to consume folic acid every day for 30 days following the last dose of pralatrexate injection, starting 10 days prior to the commencement of your treatment.
