How should this medicine be used?

Methotrexate injection comes as a powder to be mixed with liquid to be injected intramuscularly (into a muscle), intravenously (into a vein), intra-arterially (into an artery), or intrathecally (into the fluid-filled space of the spinal canal). The length of treatment depends on the types of drugs you are taking, how well your body responds to them, and the type of cancer or condition you have.

Ask your pharmacist or doctor for a copy of the manufacturer's information for the patient.

What special precautions should I follow?

Before receiving methotrexate injection,

  • tell your doctor and pharmacist if you are allergic to methotrexate, any other medications, or any of the ingredients in methotrexate injection. Ask your pharmacist for a list of the ingredients.
  • tell your doctor and pharmacist what prescription and nonprescription medications, vitamins, nutritional supplements, and herbal products you are taking or plan to take. Be sure to mention the medications listed in the IMPORTANT WARNING section and any of the following: certain antibiotics such as chloramphenicol (Chloramycetin), penicillins, and tetracylcines; folic acid (available alone or as an ingredient in some multivitamins); other medications for rheumatoid arthritis; phenytoin (Dilantin); probenecid (Benemid); proton pump inhibitors (PPIs) such as esomeprazole (Nexium), omeprazole (Prilosec, Prilosec OTC, Zegerid), pantoprazole (Protonix); sulfonamides such as co-trimoxazole (Bactrim, Septra), sulfadiazine, sulfamethizole (Urobiotic), and sulfisoxazole (Gantrisin); and theophylline (Theochron, Theolair). Your doctor may need to change the doses of your medications or monitor you carefully for side effects.
  • tell your doctor if you have or have ever had any of the conditions mentioned in the IMPORTANT WARNING section or a low level of folate in your blood.
  • do not breastfeed while you are receiving methotrexate injection.
  • you should know that methotrexate may cause dizziness or make you feel drowsy. Do not drive a car or operate machinery until you know how this medication affects you.
  • plan to avoid unnecessary or prolonged exposure to sunlight or ultraviolet light (tanning beds and sunlamps) and to wear protective clothing, sunglasses, and sunscreen. Methotrexate may make your skin sensitive to sunlight or ultraviolet light. If you have psoriasis, your sores may get worse if you expose your skin to sunlight while you are receiving methotrexate.
  • do not have any vaccinations during your treatment with methotrexate without talking to your doctor.

What special dietary instructions should I follow?

Unless your doctor tells you otherwise, continue your normal diet.

What other information should I know?

It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
