This medicine has been prescribed for you for the relief of moderate to severe pain. It contains oxycodone which belongs to a class of medicines called opioids, which are ‘pain relievers’. This medicine has been prescribed for you and should not be given to anyone else. Opioids can cause addiction and you may get withdrawal symptoms if you stop taking it suddenly. Your prescriber should have explained how long you will be using it for and when it is appropriate to stop, how to do this safely.
Talk to your doctor, pharmacist or nurse before treatment with OxyNorm injection if you:
Using this medicine regularly, particularly for a long time, can lead to addiction and may result in life threatening overdose. If you have concerns that you may become dependent on OxyNorm injection, it is important that you consult your doctor. Your doctor should have explained how long you will be using it for and when it is appropriate to stop, how to do this safely.
Rarely, increasing the dose of this medicine can make you more sensitive to pain. If this happens, you need to speak to your doctor about your treatment.
Addiction can cause withdrawal symptoms when you stop using this medicine. Withdrawal symptoms can include restlessness, difficulty sleeping, irritability, agitation, anxiety, feeling your heartbeat (palpitations), increased blood pressure, feeling or being sick, diarrhoea, loss of appetite, shaking, shivering or sweating. Your doctor will discuss with you how to gradually reduce your dose before stopping the medicine. It is important that you do not stop using the medicine suddenly as you will be more likely to experience withdrawal symptoms.
Opioids should only be used by those they are prescribed for. Do not give your medicine to anyone else. Using higher doses or more frequent doses of opioid may increase the risk of addiction. Overuse and misuse can lead to overdose and/or death.
Sleep-related breathing disorders
OxyNorm injection can cause sleep-related breathing disorders such as sleep apnoea (breathing pauses during sleep) and sleep related hypoxemia (low oxygen level in the blood). The symptoms can include breathing pauses during sleep, night awakening due to shortness of breath, difficulties to maintain sleep or excessive drowsiness during the day. If you or another person observe these symptoms, contact your doctor. A dose reduction may be considered by your doctor.
If you are going to have an operation, or have just had an operation, please tell the doctor at the hospital that you are using this medicine. Your doctor may adjust your dose.
You may experience hormonal changes while taking this medicine. Your doctor may want to monitor these changes.
Using OxyNorm injection at the same time as other medicines that slow down the central nervous system can cause slow or difficulty breathing (respiratory depression), severe sleepiness, loss of consciousness and death. These medicines include:
Because of this, your doctor will only prescribe OxyNorm injection where there are no other treatment options, and only in small doses for short periods of time. If you or your friends, family or caregivers notice that you are having difficulty breathing or that you have become very sleepy or lost consciousness you (or they) should inform your doctor immediately.
Using OxyNorm injection with medicines used to treat depression known as Selective Serotonin Re-uptake Inhibitors (SSRIs) or Serotonin Norepinephrine Re-uptake Inhibitors (SNRIs) can cause a condition known as serotonin toxicity. The symptoms of this include agitation, seeing or hearing things that aren’t real (hallucinations), loss of consciousness, a fast heartbeat, blood pressure changes, increased body temperature, muscle twitching, lack of coordination, stiffness, feeling or being sick, or diarrhoea. If you are taking SSRI or SNRI medicines such as citalopram, duloxetine, escitalopram, fluoxetine, fluvoxamine, paroxetine, sertraline or venlafaxine your doctor may reduce your dose of OxyNorm injection.
Please tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines, including medicines obtained without a prescription. Tell your doctor or pharmacist if you are taking any of the following medicines, as they may need to adjust your dose:
Drinking alcohol during your treatment with OxyNorm injection may make you sleepy or increase the risk of serious side effects such as shallow breathing with a risk of stopping breathing, and loss of consciousness. It is recommended that you do not drink alcohol while you are taking OxyNorm injection.
You should avoid drinking grapefruit juice during your treatment with this medicine.
Ask your doctor or pharmacist for advice before taking any medicine.
Do not use OxyNorm injection if you are pregnant or think you might be pregnant unless you have discussed this with your doctor and the benefits of treatment are considered to outweigh the potential harm to the baby. If you use OxyNorm injection during pregnancy your baby may become dependent and experience withdrawal symptoms after the birth which may need to be treated.
Do not use OxyNorm injection while you are breastfeeding as oxycodone passes into breast milk and will affect your baby.
