Consumer Medicine Information
What is in this leaflet
This leaflet answers some common questions about MS Mono modified release capsules ("capsules").
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 Mono capsules are taken for
MS Mono capsules contain morphine sulfate. Morphine belongs to a group of medicines called opioid analgesics.
MS Mono capsules are used to treat chronic severe pain.
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 Mono capsules. Taking it may result in physical dependence. Physical dependence means that you may experience withdrawal symptoms if you stop taking MS Mono capsules 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 Mono capsules
How much to take
Your doctor will tell you exactly how much to take.
Follow the instructions given to you by your doctor or pharmacist exactly.
How to take it
Swallow MS Mono capsules whole with water.
You can take the capsules before or after a meal.
If you have trouble swallowing, you can open your capsules and sprinkle the pellets onto soft cold food such as yoghurt, custard, apple puree or ice cream. Eat the soft food containing the pellets within 60 minutes and do not chew or crush the pellets. After eating, rinse your mouth to ensure that all the pellets have been swallowed.
The pellets may also be sprinkled into a glass of liquid (milk, orange juice or water). Drink the liquid containing the pellets within 60 minutes and do not chew or crush the pellets. If some of the pellets stick to the glass, add more liquid and swirl to pick up any remaining pellets before drinking.
Do not chew or crush them. The pellets may release all their contents at once if the pellets are chewed or crushed which can be dangerous and cause serious problems, such as an overdose which may be fatal.
You must only take MS Mono capsules 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 Mono capsules every 24 hours.
Take MS Mono capsules regularly to control the pain.
Taking them 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 Mono capsules 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 or 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 day.
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 many MS Mono capsules.
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 capsules that were 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 capsules 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 Mono capsules exactly as your doctor has prescribed.
Before you start on a new medicine, remind your doctor and pharmacist that you are taking MS Mono capsules.
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 Mono capsules.
Tolerance to morphine may develop which means that the effect of this medicine may decrease. If this happens, your doctor may review your dose so that you get adequate pain relief.
Keep enough MS Mono capsules with you to last over weekends and holidays.
Things you must not do
Do not drink alcohol while you are taking MS Mono capsules. Drinking alcohol whilst taking MS Mono capsules 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 Mono capsules 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 recommended 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 Mono capsules affect you. MS Mono capsules 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 Mono capsules. 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 Mono capsules 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 Mono capsules.
