What MST Continus tablets are and what they are used for
These tablets have been prescribed for you by your doctor to relieve severe pain over a period of 12 hours. They contain the active ingredient morphine which belongs to a group of medicines called strong analgesics or ‘painkillers’.
What you need to know before you take MST Continus tablets
Do not take MST Continus tablets if:
you are allergic to morphine or any of the other ingredients of this medicine (listed in section 6);
you have breathing problems, such as obstructive airways disease or respiratory depression. Your doctor will have told you if you have these conditions. Symptoms may include breathlessness, coughing or breathing more slowly or weakly than expected;
you have a head injury that causes a severe headache or makes you feel sick. This is because the tablets may make these symptoms worse or hide the extent of the head injury;
you have a condition where the small bowel (part of your gut) does not work properly (paralytic ileus), your stomach empties more slowly than it should (delayed gastric emptying) or you have severe pain in your abdomen;
you have recent onset liver disease;
you are taking a type of medicine known as a monoamine oxidase inhibitor (examples include tranylcypromine, phenelzine, isocarboxazid, moclobemide and linezolid), or you have taken this type of medicine in the last two weeks;
the patient is under one year of age.
If you are going to have an operation, please tell the doctor at the hospital that you are taking these tablets.
Warnings and precautions
Talk to your doctor or pharmacist before taking these tablets if you:
have breathing problems, such as impaired lung function or severe bronchial asthma. Your doctor will have told you if you have these conditions. Symptoms may include breathlessness and coughing;
have an under-active thyroid gland (hypothyroidism), severe kidney or liver problems as you may need a lower dose;
have a severe headache or feel sick as this may indicate that the pressure in your skull is increased;
suffer from, or have ever suffered from epilepsy, seizures, fits or convulsions;
have low blood pressure;
have a severe heart problem after long-term lung disease (severe cor pulmonale);
have inflammation of the pancreas (which causes severe pain in the abdomen and back) or problems with your gall bladder;
have an inflammatory bowel disorder;
have prostate problems;
have increased sensitivity to pain despite the fact that you are taking increasing doses (hyperalgesia). Your doctor will decide whether you will need a change in dose or a change in strong analgesic (“painkiller”), (see section 2);
experience weakness, fatigue, lack of appetite, nausea, vomiting or low blood pressure. This may be a symptom of the adrenal glands producing too little of the hormone ‘cortisol’, and you may need to take a hormone supplement;
have loss of libido, impotence, cessation of menstruation. This may be because of decreased sex hormone production;
have previously been dependent on drugs or alcohol. Also tell your doctor if you feel that you are becoming dependent on this medicine while you are using it. You may have started to think a lot about when you can take the next dose, even if you do not need it for the pain;
have withdrawal (abstinence) symptoms or dependence. The most common abstinence symptoms are mentioned in section 3. If this occurs, your doctor may change the type of medicine or the times between doses.
You may experience hormonal changes while taking these tablets. Your doctor may want to monitor these changes.
However if your doctor does prescribe MST Continus tablets together with sedative medicines, the dosage and duration of concomitant treatment should be limited by your doctor.
Please tell your doctor about all sedative medicines you are taking and follow your doctor’s dosage recommendation closely. It could be helpful to inform friends or relatives to be aware of the signs and symptoms stated above. Contact your doctor when experiencing such symptoms.
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines, including medicines obtained without a prescription. If you take these tablets with some other medicines, the effect of the tablets or the other medicine may be changed.
