Uses

Pralatrexate is used to treat a certain type of cancer (peripheral T-Cell lymphoma-PTCL). Pralatrexate works by slowing or stopping the growth of cancer cells.

How To Use

Read the Patient Information Leaflet if available from your pharmacist before you start using pralatrexate and each time you get a refill. If you have any questions, ask your doctor or pharmacist.

This medication is given by a health care professional in a clinic or hospital. It is injected into a vein as directed by your doctor, usually once a week for 6 weeks. Tell your doctor or nurse right away if you notice redness, pain, or swelling during your injection.

The dosage is based on your body size, medical condition, and response to treatment.

Use this medication regularly to get the most benefit from it. To help you remember, mark the days on the calendar when you need to receive the medication.

To help prevent mouth sores, your doctor may also direct you to take folic acid and give you vitamin B12 shots. Carefully follow your doctor's directions for all your medications.

Side Effects

Pain or sores in the mouth and throat may occur. Brush your teeth carefully/gently, avoid using mouthwash that contains alcohol, and rinse your mouth often with cool water mixed with baking soda or salt. It may also be best to eat soft, moist foods. Nausea may also occur. If any of these effects last or get worse, tell your doctor or pharmacist promptly.

Remember that this medication has been prescribed because your doctor has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.

Serious skin reactions can occur. Tell your doctor right away if you develop rash, peeling, sores or blisters on the skin.

Tell your doctor right away if you have any serious side effects, including:

• easy bleeding/bruising
• dehydration
• feeling weak
• looking pale
• shortness of breath

This medication may lower your ability to fight infections. This may make you more likely to get a serious (rarely fatal) infection or make any infection you have worse. Tell your doctor right away if you have any signs of infection (such as sore throat that doesn't go away, fever, chills, cough).

Pralatrexate sometimes causes side effects due to the rapid destruction of cancer cells (tumor lysis syndrome). To lower your risk, your doctor may add a medication and tell you to drink plenty of fluids. Tell your doctor right away if you have symptoms such as:

• low back/side pain (flank pain)
• signs of kidney problems (such as painful urination, pink/bloody urine, change in the amount of urine)
• muscle spasms/weakness

A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including:
