Morphine, oxycodone and fentanyl (day surgery only)
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 through a small cannula which is placed in your upper thigh.
If you need opioids after having day surgery, you will be given fentanyl through a small cannula in your hand or arm.
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 harm if taken for a long time.
Morphine is the first choice of pain medication for severe pain. Oxycodone is used for patients that are allergic or sensitive to morphine, or when the side effects of morphine are unacceptable.
Side effects of strong pain medications
All pain medications have side effects; opioids can cause drowsiness (feeling tired) 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.
