Morphine and oxycodone
You may be prescribed morphine or oxycodone whilst in hospital. These come in different forms, such as liquids, tablets (short and long acting) and injections.
Injections are only given to you if you are unable to eat or drink. The injection will be given subcutaneously (sub cut) through a small thin tube called a cannula which is placed in your upper thigh.
Strong opioid medication is for severe pain. If you are experiencing severe pain, tell the nurse who will then assess your pain and give you the pain medication you need.
Strong opioid medication is only recommended for short-term use as they can cause you harm if you take it for a long time.
Side effects of strong pain medications
All pain medications have side effects; opioids can cause drowsiness (feeling sleepy) and sometimes nausea (feeling sick) or vomiting (being sick).
Morphine and oxycodone both cause constipation.
Rare side effects include bad dreams or hallucinations.
Nausea and vomiting can be treated with anti-sickness medication and/or an Acupin.
If you have any of these side effects, please tell your nurse.
Will I become addicted to the pain medication?
Strong opioids, even when prescribed by a nurse or a doctor, have a serious risk of dependence and addiction, especially with long-term use. You will only be prescribed strong opioids for a short time, as long term use of strong opioids is not recommended.
If you are on strong opioids for more than 2 weeks, they should not be stopped suddenly. Strong opioids should be reduced over a period of time to avoid withdrawal problems. Withdrawal symptoms include muscle and bone pain, sleep problems, diarrhoea and vomiting (being sick).
For advice about stopping strong opioid medication, ask your GP.
