    Otrexup Patient Information including How Should I Take

    What should I discuss with my healthcare provider before receiving methotrexate injection?

    You should not use methotrexate if you are allergic to it. Methotrexate should not be used to treat psoriasis or rheumatoid arthritis if you have:

    • alcoholism, cirrhosis, or chronic liver disease;
    • low blood cell counts;
    • a weak immune system or bone marrow disorder; or
    • if you are pregnant or breastfeeding.

    Methotrexate is sometimes used to treat cancer in people who have a condition listed above. Your doctor will decide if this treatment is right for you.

    Tell your doctor if you have ever had:

    Methotrexate is sometimes used to treat cancer during pregnancy. However, methotrexate may cause injury or death to an unborn baby and should not be used during pregnancy to treat arthritis or psoriasis. Tell your doctor if you are pregnant.

    Methotrexate can harm an unborn baby if the mother or the father is using this medicine.

    • If you are a woman, you may need a pregnancy test before starting this treatment. Use effective birth control to prevent pregnancy while you are using methotrexate and for at least 6 months after your last dose.
    • If you are a man, use effective birth control if your sex partner is able to get pregnant. Keep using birth control for at least 3 months after your last dose.
    • Tell your doctor right away if a pregnancy occurs while either the mother or the father is using methotrexate.

    This medicine may affect fertility (ability to have children) in both men and women. However, it is important to use birth control to prevent pregnancy because methotrexate may harm the baby if a pregnancy does occur.

    Do not breastfeed while using this medicine.

    Do not give this medicine to a child without medical advice.

    How is methotrexate injection given?

    Follow all directions on your prescription label and read all medication guides or instruction sheets. Use the medicine exactly as directed.

    Methotrexate is usually given once per week. You must use the correct dose. Some people have died after incorrectly using methotrexate every day.

    Methotrexate is injected into a muscle, under the skin, or as an infusion into a vein. A healthcare provider will give you this injection and may teach you how to properly use the medication by yourself.

    Methotrexate may also be injected by a healthcare provider directly into a joint, or into the space around your spinal cord.

    Read and carefully follow any Instructions for Use provided with your medicine. You may need to mix methotrexate with a liquid (diluent) before using it. Ask your doctor or pharmacist if you don't understand all instructions.

    Prepare an injection only when you are ready to give it. Do not use if the medicine looks cloudy, has changed colors, or has particles in it. Call your pharmacist for new medicine.

    Methotrexate can be toxic to your organs, and may lower your blood cell counts. You will need frequent medical tests, and you may need an occasional liver biopsy or chest X-ray. Your cancer treatments may be delayed based on the results.

    If you need to be sedated for dental work, tell your dentist you currently use methotrexate.

    Store methotrexate in its original packaging at room temperature away from moisture, heat, and light. Do not freeze.

    A single-use vial (bottle) or auto-injector is for one use only. Use a needle and syringe only once and then place them in a puncture-proof "sharps" container. Follow state or local laws about how to dispose of this container. Keep it out of the reach of children and pets.

    Otrexup Patient Information including If I Miss a Dose

    What happens if I miss a dose?

    Call your doctor for instructions if you miss an appointment for your methotrexate injection, or if you forget to use the medicine at home.

    What happens if I overdose?

    Seek emergency medical attention or call the Poison Help line at 1-800-222-1222. An overdose of methotrexate injection can be fatal.

    What should I avoid while receiving methotrexate injection?

    Avoid exposure to sunlight or artificial UV rays (sunlamps, tanning beds, or PUVA treatment), especially if you have psoriasis. Methotrexate can make your skin more sensitive to sunlight and your psoriasis may worsen.

    Avoid drinking alcohol. It may increase your risk of liver damage.

    Do not receive a "live" vaccine while using methotrexate, or you could develop a serious infection. Live vaccines include measles, mumps, rubella (MMR), rotavirus, typhoid, yellow fever, varicella (chickenpox), zoster (shingles), and nasal flu (influenza) vaccine.

    Methotrexate may impair your thinking or reactions. Avoid driving or operating machinery until you know how this medicine will affect you.

    Methotrexate can harm your liver, especially if you also use certain medicines for infections, tuberculosis, birth control, hormone replacement, high cholesterol, heart problems, high blood pressure, seizures, pain, or arthritis (including Tylenol, Advil, Motrin, or Aleve).

    Tell your doctor about all your other medicines, especially:

    Where can I get more information?

    Your doctor or pharmacist can provide more information about methotrexate injection.
