Stop taking Dolcontin Unotard and contact your doctor immediately if you get any of the following symptoms ( anaphylactic reaction ):

  • Difficulty swallowing
  • Hives and difficulty breathing

Talk to your doctor or pharmacist if you experience any of the following symptoms while taking Dolcontin Unotard:

  • Increased pain sensitivity even though you are taking increased doses(hyperalgesia). Your doctor will decide if you must change the dose or switch to another analgesic solid (painkiller) (see section 2).
  • Weakness, fatigue, loss of appetite, nausea, vomiting, or low blood pressure. This may be a symptom that the adrenal glands produce too little of the hormone et cortisol, and you may therefore need to take hormone supplements.
  • Loss of libido, impotence, missed periods. This may be due to decreased production of sex hormones.
  • If you have once been addicted to drugs or alcohol. Also, tell us if you feel you are becoming addicted to Dolcontin Unotard while using it. You may have started thinking a lot about when you can take the next dose, even if you do not need it for the pain.
  • Withdrawal symptoms or addiction. The most common withdrawal symptoms are mentioned in section 3. If this happens, your doctor may change the type of medicine or the times between doses.

The effects of Dolcontin Unotard may lead to addiction. Proper use with prolonged, severe pain reduces the risk of addiction.
Drink alcohol while taking Dolcontin Unotard. It may make you feel more sleepy or increase the risk of serious side effects such as shallow breathing with a risk of respiratory arrest and unconsciousness. You should not drink alcohol while taking Dolcontin Unotard.

Other Medicines And Dolcontin Unotard:

Tell your doctor or pharmacist if you are taking, have recently taken, or might take other medicines. You must tell your doctor or pharmacist if you are taking the following:

  • Rifampicin to e.g. treat tuberculosis
  • Other strong painkillers (opioids)
  • Sedatives, hypnotics (eg benzodiazepines )
  • Anesthetics for anesthesia before e.g., an operation
  • Certain medicines for mental illness
  • Muscle relaxants
  • Certain antidepressants (clomipramine, amitriptyline)
  • Specific hydrochloric acid inhibitors (cimetidine, for example, for stomach ulcers )
  • Medicines for high blood pressure
  • Combined morphine agonists / antagonists (buprenorphine, nalbuphine, pentazocine)
  • Some medicines used to prevent blood clots (e.g., clopidogrel, prasugrel, ticagrelor) may have a delayed or reduced effect when taken with morphine.

Concomitant use of Dolcontin Unotard with sedatives or sleeping pills such as benzodiazepines or related drugs increases the risk of:

  • Drowsiness
  • Difficulty breathing ( respiratory depression )
  • Coma and may be life-threatening

Concomitant use should only be considered when other treatment options are lacking. However, if your doctor prescribes Dolcontin Unotard with sedative drugs, your doctor should limit the dolcontin dosering and the duration of concomitant treatment. Tell your doctor about all your sedative medicines, and follow your doctor’s dose recommendation. It may be helpful to ask friends or relatives to be aware of the signs and symptoms mentioned above. Contact a doctor when you experience such symptoms.

Avoid concomitant treatment with Dolcontin Unotard and:

  • Barbiturates (mainly used for anesthesia and severe epileptic seizures) as the combination impairs respiratory function
  • MAO inhibitors, e.g., selegiline and rasagiline (used in Parkinson’s disease ) and moclobemide (used in depression). If you have been treated with MAOIs, two weeks must pass before treatment with Dolcontin Unotard can begin.

Pregnancy, Breastfeeding, And Fertility

If you are pregnant or breast-feeding, think you may be pregnant, or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.


There is a risk that the fetus is affected. Dolcontin Unotard should, therefore, not be used during pregnancy. Always consult a doctor before using Dolcontin Unotard during pregnancy. With long-term use of Dolcontin Unotard during pregnancy, there is a risk that the newborn baby will develop drug-withdrawal symptoms ( abstinence ) that a doctor must treat.


Morphine passes into breast milk. Dolcontin Unotard should, therefore, not be used during breast-feeding. Always consult a doctor before using Dolcontin Unotard when breast-feeding.

Driving And Using Machines:

During treatment with Dolcontin Unotard, the ability to react may be reduced. This should be considered when sharper attention is required, e.g., when driving and using machines.

You are responsible for assessing whether you can drive a motor vehicle or perform work requiring sharpened attention. One of the factors that can affect your ability in these respects is the use of drugs due to their effects and side effects.

Descriptions of these effects and side effects can be found in other sections. Read all the information in this leaflet for guidance. If you are not sure, talk to your doctor or pharmacist.
