Pregnancy and breastfeeding

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

ARX MORPHINE MR tablets 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.

Addiction

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

Dependence

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

Tolerance

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

Withdrawal

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 ARX MORPHINE MR tablets and affect how it works.

Using ARX MORPHINE MR tablets 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.

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

ARX MORPHINE MR tablets may increase the anticoagulant activity of coumarin and other anticoagulants (medicines used to prevent blood clots).

ARX MORPHINE MR tablets 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 ARX MORPHINE MR tablets.

4. How do I use ARX MORPHINE MR tablets?

How to take ARX MORPHINE MR tablets

Swallow ARX MORPHINE MR tablets whole and be careful not to break, chew, crush or dissolve the tablets.

If you have trouble swallowing your tablets whole, talk to your doctor.

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

If you forget to use ARX MORPHINE MR tablets

You should take ARX MORPHINE MR tablets at the same time each day. If you miss your dose at the usual time, you may take ARX MORPHINE MR tablets as soon as you remember.

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 ARX MORPHINE MR tablets (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 ARX MORPHINE MR tablets 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
