how do i give myself an injection of methotrexate?

Administering an injection of methotrexate can seem daunting at first, but with the right guidance and preparation, it can be done safely and effectively. Here’s a step-by-step guide based on the information in my sources.

Preparation Before Injection

1. Consult Your Healthcare Provider: Always discuss with your GP, pharmacist, or rheumatologist before starting your injections. They can provide personalised advice and ensure you understand the process.

2. Gather Your Supplies:

   • Methotrexate vial or pre-filled syringe (Trexject).
   • Insulin syringes (1ml) if using a vial.
   • Alcohol swabs or cotton wool balls.
   • Sharps container for disposal.

3. Wash Your Hands: Clean your hands thoroughly with soap and water to prevent infection.

4. Clean the Injection Site: Choose a clean area of skin, preferably on the lower abdomen or thigh. You can wash it with soap and water or wipe it with an alcohol swab and let it dry for 60 seconds.

Drawing Up the Methotrexate

1. Prepare the Vial: Remove the protective cover from the methotrexate vial. If it has been used before, rub the rubber top with an alcohol swab and allow it to dry.

2. Draw Up the Medication:

   • Remove the cap from the needle.
   • Insert the needle through the rubber stopper of the vial.
   • Push the plunger down to expel any air from the syringe.
   • Pull the plunger back to draw up the required amount of methotrexate. If there’s a small air pocket, it’s not harmful if injected.

Administering the Injection

1. Pinch the Skin: Pinch about an inch of the cleaned skin to create a fold.

2. Inject the Methotrexate:

   • Insert the needle into the skin at a 90° angle, like a dart.
   • Release the skin and push the plunger down completely to inject the methotrexate.

3. Withdraw the Needle: Pull the needle straight out and apply pressure to the injection site with a cotton wool ball or tissue for a few seconds.

4. Post-Injection Care:

   • It’s normal to have slight bleeding or bruising at the injection site. Apply pressure to help it stop.
   • If methotrexate leaks out, wash your hands; it is not absorbed through the skin.

Disposal and Aftercare

1. Dispose of Used Materials: Place the syringe, any old methotrexate vials, swabs, or cotton wool balls into your sharps container. Never throw syringes or needles in general rubbish or recycling.

2. Wash Your Hands Again: After disposing of the materials, wash your hands thoroughly.

Important Considerations

• Injection Frequency: Methotrexate is typically injected once a week. If you forget a dose, inject it as soon as you remember, but do not double up on doses.

• Overdose Awareness: If you suspect an overdose, contact your doctor immediately. Symptoms may include side effects listed in your medication information.

• Injection Site Care: Avoid injecting into areas that are tender, bruised, red, hard, or scarred. If you have psoriasis, do not inject into raised or scaly skin patches.

• Consult Your Doctor: If you have any uncertainties about the dosage or the injection process, always check with your healthcare provider before proceeding.

Conclusion

Injecting methotrexate can be a straightforward process with the right preparation and care. Always prioritise your health and safety by consulting with your healthcare team and following their guidance. If you have further questions or concerns, don’t hesitate to reach out to your rheumatologist or healthcare provider for support.
