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 your calendar with a reminder.

To help prevent mouth sores and other side effects, 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.

Nausea, vomiting, constipation, or diarrhea may occur. If any of these effects last or get worse, tell your doctor or pharmacist promptly.

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.

This medication decreases bone marrow function, an effect that may lead to a low number of blood cells such as red cells, white cells, and platelets. This effect can cause anemia, decrease your body's ability to fight an infection, or cause easy bruising/bleeding. Tell your doctor right away if you develop any of the following symptoms:

• signs of liver problems (such as nausea/vomiting that doesn't stop, loss of appetite, stomach/abdominal pain, yellowing eyes/skin, dark urine)
• shortness of breath

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)
