How to take diamorphine
- Diamorphine is usually given as an injection by your nurse or doctor.
- Depending on the reason that you are taking diamorphine, your doctor may give you a second painkiller to take when you need.
Getting the most from your treatment
- Do not drink alcohol with diamorphine as this will increase the side-effects of dizziness and drowsiness.
- Taking diamorphine regularly for a long time can lead to your body becoming dependent on it, which might cause you to feel restless and irritable when you stop taking it. If you are concerned about this, discuss the problem with your doctor or pharmacist.
- If you are planning a trip abroad you are advised to carry a letter with you from your doctor because diamorphine is a controlled drug. If you plan to travel for more than 3 months, you must check with the Home Office before you travel as you will need to apply in writing for a licence to take diamorphine with you.
- If you are having any treatment like an operation or dental treatment, tell the person carrying out the treatment that you are taking diamorphine.
- If you buy any medicines, check with a pharmacist that they are safe to take with diamorphine.
