  • If you have a problem with excessive phlegm;
  • If you have recently suffered any head injury or have been told that you have raised pressure around your brain;
  • If you have liver disease;
  • If you have an inflammatory bowel disease such as ulcerative colitis;
  • If you have any problems with your stomach or bowel (where your bowel or stomach function has slowed down or stopped working) or you have severe pain in your abdomen;
  • If you often drink large amounts of alcohol;
  • If you are taking, or have recently taken (within the last 14 days) a medicine from a group of anti-depressants called monoamine oxidase inhibitors (MAOIs) see section ‘Other medicines and Morphgesic SR Tablets’;

Warnings and precautions

Talk to your doctor or pharmacist or nurse if you experience any of the following symptoms while taking Morphgesic SR Tablets:

  • If you have breathing problems such as impaired lung function;
  • If you have any problems with your thyroid or adrenal glands;
  • If you have impaired liver or kidney function;
  • If you are a man with an enlarged prostate gland;
  • If you have any problems urinating;
  • If you have epilepsy or suffer from fits (seizures);
  • If you are suffering with shock;
  • If you are suffering from myasthenia gravis (a disease which affects the muscles);
  • If you have bowel problems e.g. inflammatory or obstructive bowel disorder;
  • If you have low blood pressure and a decreased volume of blood circulating (hypovolaemia);
  • If you are addicted to any medicine like morphine;
  • If you have a severe heart problem after long-term lung disease (severe cor pulmonale);
  • If you suffer with a disease of your bile duct;
  • If you have pancreatitis (inflammation and swelling of the pancreas);
  • If you are, or have ever been, addicted to alcohol or drugs;
  • If you have previously suffered from withdrawal symptoms such as agitation, anxiety, shaking or sweating, upon stopping taking alcohol or drugs;
  • If you have a rare form of tumour affecting part of the body known as the adrenal glands (phaeochromocytoma);
  • If you are elderly;
  • If you are taking any medicine from the group of medicines known as benzodiazepines. Taking these medicines with Morphgesic SR Tablets may result in sedation, difficulties in breathing (respiratory depression), coma and may be fatal. Even if benzodiazepines are prescribed, your doctor may need to change the dose, the duration of treatment or monitor you regularly;
  • If you 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);
  • If you experience weakness, fatigue, lack of appetite, nausea, vomiting or low blood pressure. This may be a symptom of the adrenals producing too little of the hormone cortisol, and you may need to take hormone supplement;
  • If you experience loss of libido, impotence, cessation of menstruation. This may be because of decreased sex hormone production;
  • If you have once been dependent on drugs or alcohol. Also tell if you feel that you are becoming dependent on Morphgesic SR Tablets 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;
  • If you experience 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.

If any of these apply to you, or if you are not sure, tell your doctor before taking Morphgesic SR Tablets.

Please tell your doctor or pharmacist if you are taking or have recently taken any other medicines, including medicines obtained without a prescription.

Morphgesic SR Tablets must not be used together with a monoamine oxidase inhibitor, or if you have taken this type of medicine in the last two weeks (see section ‘Do not take...’). Examples include tranylcypromide, phenelzine, isocarboxazid, moclobemide and linezolid.

  • psychoses (e.g. chlorpromazine, promazine);
  • sedative or hypnotic purposes (e.g. zopiclone, zolpidem);
  • gabapentin to treat epilepsy or neuropathic pain (pain due to nerve problems);
  • other opioid analgesics such as buprenorphine, nalbuphine or pentazocine;
  • anaesthesia (e.g. thiopental, isoflurane);
