  • if you are allergic to oxycodone hydrochloride or any of the other ingredients of this medicine (listed in section 6)
  • if you have severely impaired breathing ( respiratory depression ) with too little oxygen in the blood ( hypoxia ) and/or too much carbon dioxide ( hypercapnia ) in the blood
  • if you have severe chronic lung disease (COPD = chronic obstructive pulmonary disease ), heart disease due to chronic congestion of the pulmonary circulation (cor pulmonale), or acute , severe tracheal asthma

Tell your doctor that you are being treated with OxyNorm solution for injection.

When OxyNorm is used for a long time, tolerance to the effects may mean that an increased dose is required to maintain pain control.

Prolonged use of OxyNorm may lead to physical dependence and withdrawal symptoms may occur with abrupt discontinuation of treatment. When a patient no longer needs oxycodone treatment, it is advisable to reduce the dose gradually to prevent withdrawal symptoms (see section 3 “If treatment is discontinued”).

The risk of developing physical or psychological dependence is small when used as directed by patients suffering from long-term pain and this risk must be weighed against the potential benefit. Discuss this with your doctor.

Opioids are not the first-line treatment for long-term pain that is not caused by cancer and are not recommended as the only treatment. If you are taking this medicine for this type of pain, your doctor will monitor you closely and make the necessary dose adjustments to prevent addiction and abuse.

An increased sensitivity to pain, which does not respond to a dose increase of oxycodone, may occur during treatment with OxyNorm. This is unusual, but if it does, your doctor may reduce your dose or switch to another opioid.

OxyNorm can cause sleep-related respiratory disorders such as sleep apnea (repeated pauses when you sleep) and hypoxemia (low oxygen content in the blood). Symptoms of this can be shortness of breath during sleep, waking up short of breath, difficulty sleeping, or excessive fatigue during the day. If you or anyone else observes these symptoms, consult a doctor. Your doctor may reduce your dose one.

OxyNorm solution for injection should not be used with alcohol. Alcohol can increase the risk of serious side effects such as drowsiness/drowsiness, impaired and slow breathing, unconsciousness, coma and can even be life-threatening.

Children and young people

OxyNorm solution for injection should not be given to children and adolescents under 18 years of age as there is no experience in the treatment of these patient categories.

Other medicines and OxyNorm solution for injection

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

The risk of side effects increases if you are treated with OxyNorm solution for injection and at the same time take medicines that affect brain function. In such cases, the side effects may be exacerbated. For example, fatigue/drowsiness, impaired and slow breathing may worsen and may lead to unconsciousness, coma, and may even be life-threatening.

Examples of drugs that affect brain function are:

  • Other strong painkillers ( opioids )
  • Medicines for epilepsy, pain, and anxiety (gabapentin and pregabalin)
  • Hypnotics and sedatives ( sedatives (including benzodiazepines ), hypnotics, anxiolytics )
  • Antidepressants
  • Drugs for mental or mental illness (antipsychotics such as phenothiazines and neuroleptics )
  • Medicines used under anesthesia or anesthesia
  • Muscle relaxants used to relieve muscle cramps
  • Medicines used to treat allergies, motion sickness, or nausea ( antihistamines or antiemetics)

Concomitant use of opioids, including OxyNorm, and sedatives such as benzodiazepines or similar drugs increase the risk of drowsiness, difficulty breathing ( respiratory depression ), and coma and can be life-threatening. Due to this, concomitant use should only be considered when other treatment options are not possible. If your doctor prescribes OxyNorm at the same time as sedatives, the dose and treatment time should be limited by your doctor.

Tell your doctor if you are taking any sedatives and carefully follow your doctor’s dose recommendations. It may be helpful to inform friends or relatives about paying attention to the signs and symptoms described above. Contact a doctor if you experience any of these symptoms.

The risk of side effects is increased if you take antidepressant drugs (for example, citalopram, duloxetine, escitalopram, fluoxetine, fluvoxamine, paroxetine, sertraline, venlafaxine ). These drugs can affect or be affected by oxycodone, and you may experience symptoms such as involuntary, rhythmic muscle contractions, including in the muscles that control eye movements, sudden movements, heavy sweating, tremors, excessive reflexive movements, increased muscle tension, body temperature above 38 ° C. Contact your doctor if you experience these symptoms.

If you are given OxyNorm solution for injection at the same time as medicines (coumarin derivatives) that reduce the blood’s ability to coagulate (clot), the coagulation time may increase or decrease. It may be necessary to adjust the OxyNorm dose.

Some medicines may increase the effect of OxyNorm and therefore a dose reduction may be necessary:

  • Certain types of antibiotics (macrolide antibiotics)
  • Fungicides
  • Protease inhibitors (used to treat HIV )
  • Cimetidine (antacid used to treat stomach ulcers and heartburn)

Some medicines may reduce the effect of OxyNorm and therefore an increase in dose may be necessary:

  • Rifampicin (used to treat tuberculosis )
  • Carbamazepine (used in epilepsy and certain pain conditions)
  • Phenytoin (used in epilepsy )
  • St. John’s wort

OxyNorm solution for injection with food, drink, and alcohol

If you drink alcohol while being treated with OxyNorm solution for injection, 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 being treated with OxyNorm.

You should avoid drinking grapefruit juice when you are being treated with OxyNorm solution for injection as it may increase the effect of the medicine.

Pregnancy and breastfeeding

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

The use of this product should be avoided if possible in pregnant women. Prolonged use of OxyNorm during pregnancy may cause life-threatening withdrawal symptoms in the newborn. Symptoms that should be noticed in the infant are irritability, hyperactivity, screaming, shaking, vomiting, and not gaining weight.

OxyNorm solution for injection should not be used during breastfeeding as oxycodone passes into breast milk and may cause breathing problems in the breast-fed baby.

Driving and using machines

OxyNorm impairs the ability to concentrate and react. This should be taken into account when sharper attention is required, e.g. when driving and when handling machines.

You are responsible for assessing whether you are fit to drive a motor vehicle or perform work that requires sharpened 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. Read all the information in this leaflet for guidance. If you are not sure, talk to your doctor or nurse.

OxyNorm solution for injection contains sodium

OxyNorm solution for injection contains less than 1 mmol (23 mg) sodium per ml, ie it is essentially ‘sodium-free’.

How to be treated with OxyNorm solution for injection

Your doctor will tell you what dose you are taking and how to get it. If you have any further questions, ask your doctor or healthcare professional.

Dose one is determined individually for each patient and is tailored to your pain. You will normally be given OxyNorm solution for injection by a doctor or nurse.

For information on handling, see information for physicians and healthcare professionals.

If you take more OxyNorm than you should

OxyNorm solution for injection will be given to you by a doctor or other healthcare professional and it is, therefore, unlikely that you will receive too much. If you think you have ingested too much medicine or if e.g. If a child has ingested the medicine by mistake, contact a doctor at the hospital for an assessment of the risk and advice.

The following symptoms may occur with overdose: decreased pupil size, impaired breathing ( respiratory depression, pulmonary edema ), muscle weakness, slow heart rate, and drop in blood pressure. In severe cases, drowsiness and unconsciousness ( coma ) may occur.

If a dose has been missed

Ask your doctor or healthcare professional if you think you have not received OxyNorm.

If treatment is stopped

Contact your doctor if you wish to discontinue treatment with OxyNorm.

If use is stopped abruptly after a long period of treatment, withdrawal symptoms such as restlessness, anxiety, anxiety, insomnia, involuntary muscle contractions, tremors, and gastrointestinal problems may occur. Your doctor will tell you how to stop the treatment to reduce the risk of withdrawal symptoms, usually done by gradually reducing the dose.

If you have any further questions on the use of this product, ask your doctor or nurse.
