What Sendolor is and what it is used for

Sendolor contains the active substance morphine. Morphine belongs to a group of drugs called strong analgesics or “painkillers”. Sendolor is used to treat severe acute pain, cancer pain, and breakthrough pain in cancer.


Morphine contained in Sendolor may also be approved for the treatment of other conditions not mentioned in this leaflet. Ask your doctor, pharmacist, or another healthcare professional if you have further questions, and always follow their instructions.

What you need to know before using Sendolor

Do not use Sendolor

– If you are allergic to morphine hydrochloride or any of the other ingredients of this medicine (listed in section 6)
– If you have large amounts of mucus in your airways
– If you have acute liver disease
– If you have impaired breathing (shortness of breath)
– If you feel upset/worried when you are under the influence of alcohol or drugs for sleep problems

Warnings and cautions

This drug carries a risk of addiction and often addiction. Tolerance may develop (a higher dose is needed to get the same pain relief).
Talk to your doctor, pharmacist, or nurse before using Sendolor if you have:
– asthma
– cyanosis (bluish discoloration of the skin)
– head injuries
– low blood pressure with reduced blood volume
– underactive thyroid gland
– impaired liver function
– impaired kidney function
– inflammatory intestinal disease and disorders of the normal function of the gastrointestinal tract
– pancreatitis
– biliary spasm
– urinary tract spasm
– seizures (abnormal, involuntary contractions of muscles)
– withdrawal symptoms


Talk to your doctor, pharmacist, or nurse if you experience any of the following symptoms while using Sendolor:
– Increased sensitivity to pain even though you are taking increasing doses (hyperalgesia). Your doctor will decide if you need to change the dose or switch to another strong analgesic (painkiller), (see section 2).
Weakness, fatigue, loss of appetite, nausea, vomiting, or low blood pressure. This may be a symptom that the adrenal glands are producing 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 that you are becoming addicted to Sendolor 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.

Children and young people

All children, especially newborns, are at risk of having respiratory problems with this medicine. The doctor gives morphine with special caution to children under one year of age.

Other medicines and Sendolor

Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines.

  • Concomitant use of Sendolor and sedatives such as benzodiazepines or related agents increase the risk of drowsiness, low blood pressure, difficulty breathing ( respiratory depression ), and coma, and may be life-threatening. Concomitant use should therefore only be considered when other treatment options are lacking. However, if your doctor prescribes Sendolor
    with sedatives, your doctor should limit the dose and duration of concomitant treatment. Tell your doctor about all the sedative medicines you are taking, and carefully 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.
  • Rifampicin ( antibiotics ) can make morphine disappear faster from the body.
  • Some medicines used to prevent blood clots (eg clopidogrel, prasugrel, ticagrelor) may have a delayed or reduced effect when taken with morphine.
  • Cimetidine increases the analgesic effect of morphine without major effects on respiratory capacity.
  • Nimodipine, a calcium channel blocker, enhances the analgesic effect in cancer patients who need regular morphine dose increases to control the pain.
  • MAO inhibitors (used to treat depression) may increase the effects of morphine on respiration and blood pressure (shortness of breath and low blood pressure ).
  • Serotonin poisoning (a neurotransmitter) cannot be ruled out in combination with morphine and MAO inhibitors (used to treat depression).
  • Combined treatment with morphine stimulants/inhibitors (buprenorphine, nalbuphine, pentazocine (analgesic opioids )) reduces the analgesic effect of morphine and thus increases the risk of withdrawal symptoms.

Sendolor with food, drink, and alcohol

Sendolor may cause impaired breathability, which may be exacerbated in combination with alcohol. Avoid alcohol (even small amounts) during treatment with this medicine.

Pregnancy, breastfeeding, and fertility

If you are pregnant or breastfeeding, think you may be pregnant, or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine. With long-term use of Sendolor during pregnancy, there is a risk that the newborn baby will develop symptoms of drug withdrawal ( abstinence ) which must be treated by a doctor.

Morphine can harm the fetus and has adverse effects on fertility. Therefore, fertile men and women should use effective contraception.


Morphine is excreted in breast milk. Sendolor should not be used during breastfeeding.

Driving and using machines

Morphine affects the ability to drive and use machines. This should be considered when sharper attention is required, e.g. while driving.
You are responsible for assessing whether you are fit to drive a motor vehicle or perform work that requires increased attention. One of the factors that can affect your ability in these respects is the use of drugs due to their effects and/or side effects. Descriptions of these effects and side effects can be found in other sections. Therefore, read all the information in this leaflet for
guidance. If you are not sure, talk to your doctor or pharmacist.

If you forget to use Sendolor

Do not take a double dose to make up for a forgotten dose.

If you stop using Sendolor
