Consumer Medicine Information
What is in this leaflet
This leaflet answers some common questions about Methotrexate Injection. It does not contain all the available information. It does not take the place of talking to your doctor or pharmacist.

If you have any concerns about being given this medicine, ask your doctor or pharmacist.
Keep this leaflet. You may need to read it again.
What Methotrexate Injection is used for
Methotrexate is used to treat some types of cancers. It may also be used in severe psoriasis when these conditions o not improve with other medicines.
This medicine belongs to a group of medicines called antineoplastic or cytotoxic medicines. You may also hear of these being called chemotherapy medicines.
This medicine works by blocking an enzyme needed by body cells to live. This interferes with the growth of some cells that are growing rapidly, such as skin cells in psoriasis and cancer cells.
Ask your doctor if you have any questions about why this medicine has been prescribed for you. Your doctor may have prescribed it for another reason.
This medicine is not addictive.
This medicine is available only with a doctor’s prescription.

Males: tell your doctor or pharmacist if your partner intends to become pregnant while you are being given methotrexate or shortly after you have stopped treatment with methotrexate.

How Methotrexate Injection is given
How much is given
Your doctor will decide what dose of methotrexate you will receive. This depends on your condition and other factors, such as your weight, and other medicines you are being given.
This medicine may be given alone or in combination with other drugs. It may be given as a short course or on an ongoing basis.
Additional treatment may not be repeated until your blood cell numbers return to acceptable levels and any unwanted effects have been controlled.
For cancer treatment, several courses of methotrexate therapy may be needed depending on your response to treatment.
For the treatment of psoriasis, methotrexate therapy is usually required long term.
Ask your doctor if you want to know more about the dose of Methotrexate Injection you receive.
How it is given
Methotrexate Injection may be given as an injection into a muscle, a vein, an artery or into the spine.
Methotrexate Injection must only be given by a doctor or nurse.
If you have too much (overdose)
Immediately telephone your doctor or the Poisons Information Centre (telephone 13 11 26 in Australia) for advice, or go to Accident and Emergency at your nearest hospital, if you think you or anyone else may have taken too much Methotrexate. Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.
Symptoms of a methotrexate overdose may include the side effects listed below in the ‘Side effects’ section, but are usually of a more severe nature. They may include blood in your bowel motions or black, tarry bowel motions, bleeding, nausea, vomiting, mouth ulcers and severe infections.
While you are being given Methotrexate Injection
Things you must do
If you are about to be started on any new medicine, remind your doctor and pharmacist that you are being given methotrexate.
Tell any other doctors, dentists, and pharmacists who are treating you that you are being given this medicine.
If you are going to have surgery, tell the surgeon, anaesthetist or dentist that you are taking this medicine. It may affect other medicines used during surgery.
Keep all of your doctor’s appointments so your progress can be checked. Your doctor may want to check your blood pressure and do some blood and other tests from time to time to check on your progress and to check for any unwanted side effects.
Be careful to use an effective method of birth control while you are being treated with methotrexate and for at least 12 weeks after stopping treatment. A barrier method of birth control, such as a condom, should be used. Your doctor will tell you what forms of contraception are suitable and when it is safe to stop using contraception if you wish to do so.
If you or your partner becomes pregnant while you are being treated with methotrexate, or for up to 12 weeks afterwards, tell your doctor immediately.
Protect your skin when you are in the sun, especially between 10am and 3pm. If outdoors, wear protective clothing and use a 15+ (minimum) sunscreen. Avoid exposure to sunlamps. Methotrexate may cause your skin to be much more sensitive to sunlight than it is normally. Exposure to sunlight may cause a skin rash, itching, redness, or a severe sunburn.
Discuss with your doctor how much water or fluids you should have whilst you are being given this medicine. Inadequate fluid intake can increase the side effects of this medicine.
Ask your doctor if there are any precautions you need to take to prevent your urine becoming too acidic. Acidic urine can increase the side effects of this medicine.
Methotrexate can lower the number of white blood cells and platelets in your blood. This means that you have an increased chance of getting an infection or bleeding. The following precautions should be taken to reduce your risk of infection or bleeding:
- Avoid people who have infections. Check with your doctor immediately if you think you may be getting an infection, or if you get a fever, chills, cough, hoarse throat, lower back or side pain or find it painful or difficult to urinate.
- Be careful when using a toothbrush, toothpick or dental floss. Your doctor, dentist, nurse or pharmacist may recommend other ways to clean your teeth and gums. Check with your doctor before having any dental work.
- Be careful not to cut yourself when you are using sharp objects such as a razor or nail cutters.
- Avoid contact sports or other situations where you may bruise or get injured.
Methotrexate may be excreted in body fluids and waste, including blood, urine, faeces, vomitus and semen. In general, precautions to protect other people should be taken while you are receiving methotrexate and for one week after the treatment period by:
- Flushing the toilet twice to dispose of any body fluids and waste.
- Wearing gloves to clean any spill of body fluid or waste. Use paper towels or old rags, a strong solution of non-bleaching detergent and large amounts of water to mop up the spill. Discard the towels or rags into a separate waste bag and dispose of fluids in the toilet.
- Washing linen or clothing that is heavily contaminated by body fluids or waste separately from other items. Use a strong solution of non-bleaching detergent and large amounts of water.
- Placing soiled disposable nappies and other pads in a plastic bag, seal and dispose into the garbage.
- For sexual intercourse, use a barrier method such as a condom.
Things you must not do
You must not drink alcohol whilst you are being given this medicine. Alcohol may increase the side effects of methotrexate.
Things to be careful of
Be careful driving or operating machinery until you know how methotrexate affects you. This medicine may cause dizziness, drowsiness or tiredness in some people. If you have any of these symptoms, do not drive, operate machinery or do anything else that could be dangerous.
