- If you have myasthenia gravis (a muscle weakening disease).
- If you have pancreatitis (inflammation of the pancreas).
- If you have toxic psychosis (a mental health problem).
- If you are pregnant, trying for a baby or breast-feeding.
- If you are taking other medicines, including those available to buy without a prescription, herbal or complementary medicines. It is particularly important that you tell your doctor if you have taken monoamine oxidase inhibitors (a type of antidepressant) in the last 2 weeks.
- If you have ever had an allergic reaction to this or to any other medicine.
How to take hydromorphone
- Before beginning treatment, read the manufacturer's printed information leaflet.
- Take hydromorphone exactly as directed by your doctor.
- If you find it difficult to swallow the capsules, they can be opened and the contents sprinkled onto soft food such as yoghurt before eating. Do not chew or crush the contents of the capsules.
Getting the most from your treatment
- Avoid alcoholic drinks. Alcohol will increase the side-effects of hydromorphone.
- If you are having any treatment like an operation or dental treatment, tell the person carrying out the treatment that you are taking hydromorphone.
- If you buy any medicines, check with a pharmacist that they are safe to take with hydromorphone.
- If you are planning a trip abroad you are advised to carry a letter with you from your doctor because hydromorphone 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 hydromorphone with you.
- Do not stop taking these capsules without speaking with your doctor first, as stopping suddenly can cause problems such as agitation, anxiety, shaking and sweating. If you want to stop taking hydromorphone your doctor will reduce your dose gradually.
