What is in this leaflet
This leaflet answers some common questions about MS Contin modified release granules ("suspension").
It does not contain all the available information. It does not take the place of talking to your doctor or pharmacist.
All medicines have risks and benefits. Your doctor has weighed the risks of you taking this medicine against the benefits they expect it will have for you.
If you have any concerns about using this medicine, ask your doctor or pharmacist.
Keep this leaflet with the medicine.
You may need to read it again.
What MS Contin suspension is used for
MS Contin suspension contains morphine sulfate. Morphine belongs to a group of medicines called opioid analgesics.
MS Contin suspension is used to treat chronic severe pain.
MS Contin suspension contains modified release granules for dispersing in water before taking orally (oral suspension).
Ask your doctor if you have any questions about why it has been prescribed for you.
As with all strong painkillers, your body may become used to you taking MS Contin suspension. Taking it may result in physical dependence. Physical dependence means that you may experience withdrawal symptoms if you stop taking MS Contin suspension suddenly, so it is important to take it exactly as directed by your doctor.
This medicine is only available with a doctor's prescription.

How to take MS Contin suspension
How much to take
Your doctor will tell you exactly how much to take.
Follow the instructions your doctor or pharmacist gives you exactly.
How to take it
The entire contents of the sachet of MS Contin suspension are to be added to water and mixed thoroughly.
For one sachet of 20 mg, 30 mg or 60 mg, use 10 mL (about 2 teaspoons) of water.
For one sachet of 100 mg, use 20 mL (about 4 teaspoons) of water.
For one sachet of 200 mg, use 30 mL (about 6 teaspoons) of water.
Cut or tear the top off the sachet. Empty the contents into the measuring cup of water. Stir with a spoon for 10 seconds. The suspension contains tiny granules that will not dissolve.
Swallow all the suspension at once and be careful not to chew or crush the granules.
The granules may release all their contents at once if chewed or crushed which can be dangerous and cause serious problems, such as an overdose which may be fatal.
If any suspension remains in the cup, rinse with a little more water and swallow.
Take with food where possible.
You must only take MS Contin suspension by mouth.
Taking this medicine in a manner other than that prescribed by your doctor can be harmful to your health.
When to take it
Take MS Contin suspension every 12 hours.
Take MS Contin suspension regularly to control the pain.
Taking it at the same time each day will assist in ensuring the best effect in improving your pain. If, however, you begin to experience worsening pain and you are taking your MS Contin suspension as prescribed, contact your doctor as your dosage may have to be reviewed.
How long to take it
Continue taking your medicine for as long as your doctor tells you.
If you stop taking this medicine suddenly, your pain may worsen and you may experience withdrawal symptoms such as:
- body aches
- loss of appetite, nausea, stomach cramps or diarrhoea
- fast heart rate
- sneezing or runny nose
- chills, tremors, shivering or fever
- trouble sleeping
- increased sweating and yawning
- nervousness and restlessness.
If you forget to take it
If you forget to take your dose, contact your doctor or pharmacist for advice.
Do not take a double dose to make up for the dose you have missed.
This will increase the chance of you getting unwanted side effects.
If you have trouble remembering when to take your medicine, ask your pharmacist for hints.
For example, take your medicine at the same time each morning and evening such as 8 a.m. and 8 p.m.
If you take too much (overdose)
Immediately telephone your doctor or the Poisons Information Centre (telephone 13 11 26) for advice, or go to Accident and Emergency at your nearest hospital, if you think that you or anyone else may have taken too much MS Contin suspension.
Do this even if there are no signs of discomfort or poisoning.
You may need urgent medical attention.
Keep telephone numbers for these places handy.
You should also follow the above steps if someone other than you has accidentally taken the suspension that was prescribed for you.
If someone takes an overdose they may experience difficulties in breathing, become drowsy and tired, lack muscle tone, have cold or clammy skin, have constricted pupils, have very low blood pressure or slow heart rate, and possibly may even become unconscious or die.
When seeking medical attention, take this leaflet and any remaining suspension with you to show the doctor. Also tell them about any other medicines or alcohol which have been taken.
While you are taking it
Things you must do
Take MS Contin suspension exactly as your doctor has prescribed.
Before you start on a new medicine, remind your doctor and pharmacist that you are taking MS Contin suspension.
Tell any other doctors, dentists and pharmacists who treat you that you are taking this medicine.
If you are about to have any blood tests, tell your doctor that you are being given this medicine.
It may interfere with the results of some tests.
If you are going to have surgery, tell the surgeon or anaesthetist that you are taking this medicine.
It may affect other medicines used during surgery.
If you become pregnant while taking this medicine, tell your doctor immediately.
Keep all of your doctor's appointments so that your progress can be checked.
Tell your doctor if your pain is getting worse. Also tell your doctor if you are having any problems or difficulties while you are being treated with MS Contin suspension.
Tolerance to morphine may develop which means that the effect of the medicine may decrease. If this happens, your doctor may review your dose so that you get adequate pain relief.
Keep enough MS Contin suspension with you to last over weekends and holidays.
Things you must not do
Do not drink alcohol while you are taking MS Contin suspension.
Drinking alcohol whilst taking MS Contin suspension may make you feel more sleepy and increase the risk of serious side effects, such as shallow breathing with the risk of stopping breathing and loss of consciousness.
Do not take MS Contin suspension to treat any other complaint unless your doctor tells you to.
Do not give your medicine to anyone else, even if they have the same condition as you.
Do not stop taking your medicine, exceed the dose prescribed by your doctor, or change the dosage without checking with your doctor.
Over time your body may become used to morphine. If you stop taking it suddenly, your pain may worsen and you may experience unwanted side effects such as withdrawal symptoms. This is called physical dependence.
If you need to stop taking this medicine, your doctor will gradually reduce the amount you take each day, if possible, before stopping the medicine completely.
Things to be careful of
Do not drive or operate machinery until you know how MS Contin suspension affects you.
MS Contin suspension may cause drowsiness, dizziness, hallucinations, confusion, vision problems or may affect alertness. If you are affected, you should not drive or operate machinery. Discuss these effects with your doctor.
Be careful if you are elderly, unwell or taking other medicines.
Some people may experience side effects such as drowsiness, dizziness and unsteadiness, which may increase the risk of a fall.
If you feel light-headed, dizzy or faint when getting out of bed or standing up, get up slowly.
Standing up slowly will help your body get used to the change in position and blood pressure. If this problem continues or gets worse, talk to your doctor.
Tell your doctor if you suffer from nausea or vomiting when taking MS Contin suspension.
If you vomit after taking your dose, your pain may come back as you may not have absorbed your medicine. If this happens speak to your doctor. Your doctor may prescribe some medicine to help stop vomiting.
Tell your doctor if taking MS Contin suspension causes constipation.
Your doctor can advise you about your diet, the proper use of laxatives or alternative treatments and suitable exercise you can do to help manage this.
There is potential for abuse of morphine and the development of addiction to morphine. It is important that you discuss this issue with your doctor.
All medicines may have some unwanted side effects. Sometimes they are serious but most of the time they are not. Your doctor has weighed the risks of using this medicine against the benefits they expect it will have for you.
Do not be alarmed by this list of possible side effects.
Not everybody experiences them.
Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking MS Contin suspension.
