What Morphine Juno is used for
Morphine is a pain reliever that belongs to a group of medicines called opioid analgesics. Morphine acts in the brain and spinal cord.
It is used most commonly for relief of severe pain. It may also be used just before or during an operation to help the anaesthetic work better.
Your doctor may have prescribed morphine for another reason.
Ask your doctor if you have any questions about why morphine has been prescribed for you.
Morphine may produce physical dependency if used for a long time (ie more than two weeks). Physical dependency means you may experience unpleasant feelings if you stop morphine suddenly.
However, it is also important to keep your pain under control. Your doctor can advise you on how to manage this.
This medicine is available only with a doctor’s prescription.

How Morphine Juno is given
How much is given
Your doctor will decide what dose of morphine you will receive. This depends on your condition and other factors, such as your weight.
How it is given
Your doctor or nurse will usually give morphine to you.
Morphine can be given as:
- an injection into a muscle,
- a slow injection into a vein,
- an injection under the skin or
- by a method called patient-controlled analgesia; this method allows you, the patient, to control the amount of morphine you wish to receive. On experiencing pain, you can press a button, which allows a dose of morphine to be administered to you. To prevent you receiving too much morphine, there is a “lockout” period built into the pump which prevents continuous injection of morphine.
Your doctor will decide the most appropriate way for you to be given morphine.
If you take too much (overdose)
If you have received too much morphine, you may have symptoms which include severe drowsiness, slow or troubled breathing, severe weakness, slow heart beat, pale and cold skin.
Immediately telephone your doctor or the Poisons Information Centre (Australia on 131 126) for advice, or go to Accident and Emergency at the nearest hospital, if you think that you or anyone else may have taken too much Morphine.
Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.
While you are being given Morphine Juno
Things you must do
Tell any other doctors, dentists, and pharmacists who are treating you that you are being given morphine.
If you are about to be started on any new medicine, tell your doctor, dentist or pharmacist that you are being given morphine.
If you plan to have surgery that needs a general anaesthetic, tell your doctor or dentist that you are being given morphine.
If you become pregnant while you are being treated with morphine, tell your doctor or pharmacist immediately.
Things you must not do
Do not give Morphine Juno to anyone else, even if they have the same condition as you.
Do not use Morphine Juno to treat any other complaints unless your doctor tells you to.
Do not stop using morphine, or lower the dosage, without checking with your doctor or pharmacist.
If you have been using morphine for more than two weeks, you may experience unpleasant feelings if you stop morphine suddenly.
Your doctor will probably want you to gradually reduce the amount of morphine you are using, before stopping it completely.
Do not take any other medicines, whether they are prescription or over-the- counter medicines, unless they have been approved or recommended by a doctor or pharmacist who knows you are being given morphine.
Things to be careful of
Be careful driving or operating machinery until you know how morphine affects you.
Morphine may cause drowsiness, and impairment of co-ordination, in some people. Make sure you know how you react to morphine.
Do not drive a car, operate machinery, or do anything else that could be dangerous if you are drowsy or feeling uncoordinated.
Do not drink alcohol, while you are undergoing treatment with morphine, unless otherwise advised by your doctor or pharmacist, as drowsiness and coordination impairment may be worse.
As morphine may cause nausea and vomiting, your doctor is likely to prescribe medicine for you to take/receive before the morphine, to stop you feeling sick. Morphine may also cause constipation, so your doctor is likely to prescribe laxatives to prevent this happening.
Tell your doctor, pharmacist or nurse if you have any concerns about being given morphine.
Tell your doctor or pharmacist as soon as possible if you do not feel well while you are being given morphine.
Morphine helps most people with severe pain, but it may have unwanted side effects in a few people.
