ORDINE® oral solution


Limitations of use

ORDINE should only be used when your doctor decides that other treatment options are not able to effectively manage your pain or you cannot tolerate them.

Hazardous and harmful use

ORDINE poses risks of abuse, misuse and addiction which can lead to overdose and death. Your doctor will monitor you regularly during treatment.

Life threatening respiratory depression

ORDINE can cause life-threatening or fatal breathing problems (slow, shallow, unusual or no breathing) even when used as recommended. These problems can occur at any time during use, but the risk is higher when first starting ORDINE and after a dose increase, if you are older, or have an existing problem with your lungs. Your doctor will monitor you and change the dose as appropriate.

Use of other medicines while using ORDINE

Using ORDINE with other medicines that can make you feel drowsy such as sleeping tablets (e.g. benzodiazepines), other pain relievers, antihistamines, antidepressants, antipsychotics, gabapentinoids (e.g. gabapentin and pregabalin), cannabis and alcohol may result in severe drowsiness, decreased awareness, breathing problems, coma and death. Your doctor will minimise the dose and duration of use; and monitor you for signs and symptoms of breathing difficulties and sedation. You must not drink alcohol while using ORDINE.

1. Why am I using ORDINE?

ORDINE contains the active ingredient morphine hydrochloride trihydrate. Morphine belongs to a group of medicines called opioid analgesics.

ORDINE is used to provide the short-term management of severe pain for which other treatment options have failed or are otherwise inappropriate to provide sufficient management of pain.

2. What should I know before I use ORDINE?


Do not use ORDINE if:

  • you are allergic to morphine, or any of the ingredients listed at the end of this leaflet. Always check the ingredients to make sure you can use this medicine.
  • you have acute breathing difficulties such as bronchitis or asthma
  • you have severe abdominal pain with bloating, cramps or vomiting
  • you have a condition where your small bowel does not work properly
  • you take medicine for depression called a ‘monoamine oxidase inhibitor’ or have taken any in the last two weeks
  • you are pregnant or in labour.

Check with your doctor if you:

  • are severely drowsy, have a reduced level of consciousness or are feeling faint or dizzy upon standing
  • have heart problems or heart disease
  • have low blood pressure
  • have chronic lung disease
  • suffer from sleep apnoea (temporarily stopping breathing while you sleep)
  • have just drunk a large amount of alcohol, regularly drink large amounts of alcohol or have confusion and shaking due to stopping drinking alcohol
  • suffer from convulsions, fits or seizures
  • have a head injury, brain tumour or increased pressure in your head
  • are about to have surgery, had recent gastrointestinal surgery or have had other surgery in the last 24 hours
  • have chronic liver or kidney disease
  • have increased prostate size or difficulty passing urine
  • have problems with your gall bladder
  • have problems with or recent surgery of your bile duct
  • have inflammation of the pancreas
  • have adrenal glands which are not working properly
  • have an underactive thyroid gland
  • have a severe mental condition involving losing contact with reality or an inability to think clearly
  • have an addiction or history of abuse of alcohol, opioids or other drugs.

During treatment, you may be at risk of developing certain side effects. It is important you understand these risks and how to monitor for them. See additional information under Section 6. Are there any side effects?

Pregnancy and breastfeeding

Check with your doctor if you are pregnant or intend to become pregnant.

ORDINE given to the mother during labour can cause breathing problems and signs of withdrawal in the newborn.

Talk to your doctor if you are breastfeeding or intend to breastfeed. Low levels of opioid analgesics have been detected in human milk.


You can become addicted to ORDINE even if you take it exactly as prescribed. ORDINE may become habit forming causing mental and physical dependence. If abused, it may become less able to reduce pain.


As with all other opioid containing products, your body may become used to you taking ORDINE. Taking it may result in physical dependence. Physical dependence means that you may experience withdrawal symptoms if you stop taking ORDINE suddenly, so it is important to take it exactly as directed by your doctor.


Tolerance to ORDINE may develop, which means that the effect of the medicine may decrease. If this happens, more may be needed to maintain the same effect.


Continue taking your medicine for as long as your doctor tells you. If you stop having this medicine suddenly, your pain may worsen and you may experience some or all of the following withdrawal symptoms:

  • nervousness, restlessness, agitation, trouble sleeping or anxiety
  • body aches, weakness or stomach cramps
  • loss of appetite, nausea, vomiting or diarrhoea
  • increased heart rate, breathing rate or pupil size
  • watery eyes, runny nose, chills or yawning
  • increased sweating.

3. What if I am taking other medicines?

Tell your doctor or pharmacist if you are taking any other medicines, including any medicines, vitamins or supplements that you buy without a prescription from your pharmacy, supermarket or health food shop.

Some medicines may interfere with ORDINE and affect how it works.

Using ORDINE with medicines that can make you feel drowsy may result in severe drowsiness, decreased awareness, breathing problems, coma and death. These medicines include:

  • sleeping tablets and other sedatives (including benzodiazepines and barbiturates)
  • gabapentinoids
  • cannabis
  • antihistamines
  • anxiolytics
  • general anaesthetics
  • antiemetics
  • antidepressants (including tricyclic antidepressants)
  • antipsychotics (including phenothiazines)
  • neuroleptics
  • beta-blockers (medicines used to treat high blood pressure)
  • other opioids
  • alcohol.

ORDINE may enhance the action of neuromuscular blocking agents (medicines used to relax muscles) and affect your breathing.

ORDINE may increase the anticoagulant activity of coumarin and other anticoagulants (medicines used to prevent blood clots).

ORDINE should not be used if you are taking non-selective monoamine oxidase inhibitors (MAOIs) or within 14 days of stopping such treatment.

Check with your doctor or pharmacist if you are not sure about what medicines, vitamins or supplements you are taking and if these affect ORDINE.

4. How do I use ORDINE?

How much to take

  • Your doctor will tell you how much to take.
  • Follow the instructions provided and use ORDINE until your doctor tells you to stop.

When to take ORDINE

  • Take ORDINE every 4 hours or as directed by your doctor.
  • Take ORDINE at about the same time each day.
  • ORDINE can be taken before or after food, but try to take it the same way every time.

If you begin to experience pain, tell your doctor as your dosage may have to be reviewed.

How to take ORDINE

  • Measure the dose accurately with a medicine measure. Using a medicine measure such as a measuring glass or oral syringe, will make sure that you get the correct dose. You can buy a medicine measure from your pharmacist.
  • Wipe the neck of the bottle and the cap after use to assist with re-opening.

If you forget to use ORDINE

If you are taking regular doses of ORDINE, you should take it at the same time each day. If you miss your dose at the usual time, you may take ORDINE as soon as you remember or think you need it.

If it is almost time for your next dose, skip the dose you missed and take your next dose when you are meant to.

Do not take a double dose to make up for the dose you missed.

This may increase the chance of getting unwanted side effects including severe drowsiness, decreased awareness, breathing problems, coma and death.

If you use too much ORDINE (overdose)

If you or someone else receive too much (overdose), and experience one or more of the symptoms below, call triple zero (000) for an ambulance. Keep the person awake by talking to them or gently shaking them every now and then. You should follow the above steps even if someone other than you have accidentally used ORDINE that was prescribed for you. If someone takes an overdose, they may experience one or more of the following symptoms:

  • slow, unusual or difficult breathing
  • drowsiness, dizziness or unconsciousness
  • slow or weak heartbeat
  • nausea or vomiting
  • convulsions or fits.

If you think you or someone else may have used too much ORDINE you should immediately:

  • phone the Poisons Information Centre (by calling 13 11 26), or
  • contact your doctor, or
  • go to the Emergency Department at your nearest hospital.

You should do this even if there are no signs of discomfort or poisoning.

When seeking medical attention, take this leaflet and remaining medicine with you to show the doctor. Also tell them about any other medicines or alcohol which have been taken.

5. What should I know while using ORDINE?

Things you should do

Call your doctor straight away if you:

  • become pregnant
  • feel your pain is getting worse.

Remind any doctor or dentist or pharmacist you visit that you are using ORDINE.

If you are going to have surgery, tell the surgeon or anaesthetist that you are taking this medicine.

Things you should not do

Driving or using machines

Be careful before you drive or use any machines or tools until you know how ORDINE affects you.

ORDINE may cause drowsiness or impair mental and/or physical ability in some people.

Tell your doctor if you drink alcohol.

Alcohol may make you feel more sleepy, and could increase the risk of serious side effects, such as shallow breathing with the risk of stopping breathing and loss of consciousness.
