Consumer Information

This information was provided by the drug’s manufacturer when this drug product was approved for sale in Canada. It is designed for consumers and care givers. It is a summary of information about the drug and will not tell you everything about the drug. Contact your doctor or pharmacist if you have any questions about the drug.

What the medication is used for

Jamp-Methotrexate belongs to a group of medicines known as antimetabolites. It is used in high doses to treat many types of cancers, including breast cancer, Non- Hodgkin's lymphoma and leukemia. At lower doses, it may also be used to treat psoriasis and rheumatoid arthritis.

What it does

Jamp-Methotrexate works by blocking an enzyme needed by body cells to live. This interferes with the growth of some cells, such as skin cells in psoriasis that are growing rapidly. In rheumatoid arthritis, Jamp-Methotrexate acts on the inflammatory cells that cause joint swelling. Jamp-Methotrexate therapy is used to control psoriasis and rheumatoid arthritis but it will not cure them. In cancer, Jamp- Methotrexate works by blocking an enzyme process in cancer cells so that they cannot grow. Some normal cells in the body may be affected as well.

Jamp-Methotrexate increases sensitivity to sunlight. Avoid sun exposure and do not use sunlamp while taking this drug.
Methotrexate can cause sudden bleeding in the lungs. This is called Pulmonary alveolar haemorrhage. If you suddenly spit or cough up blood you must go to the hospital right away. You will need emergency care. This occurs in patients with some existing health problems. Some examples are rheumatic disorder (such as pain in your joints) or vasculitis such as swelling in an artery or vein.

Precautions While Using This Medicine

  • Do not take Jamp-Methotrexate daily or more than the dose prescribed. Methotrexate can cause serious toxic reactions which may result in death.
  • Do not drink alcohol.
  • Do not drive a car or operate machinery until you know how Jamp-Methotrexate affects you since the drug may cause dizziness and fatigue.
  • Drink extra fluid to prevent kidney problems.
  • Have regular blood tests to reduce the risk of infection or bleeding. Methotrexate can lower the number of white blood cells and there is an increased risk of infection or bleeding.
  • Talk to your doctor if you need a vaccination. Live vaccines may cause severe infections. Live vaccines or contact with any individual who has had a live vaccination should be avoided, since your ability to fight an infection (immune system) is decreased while taking Jamp-Methotrexate.
