- if you are also taking a type of medicine known as MAO inhibitors (generally used for the treatment of depression or Parkinson’s disease).
- if you feel you need to take more of Oxylan to get the same level of pain relief, this may mean you are becoming tolerant to the effects of this medicine or are becoming addicted to it. Speak to your prescriber who will discuss your treatment and may change your dose or switch you to an alternative pain reliever.
Taking this medicine regularly, particularly for a long time, can lead to addiction (read more under “Tolerance, dependence and addiction” below). Your prescriber should have explained how long you will be taking 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 prescriber about your treatment.
Tolerance, dependence and addiction
This medicine contains oxycodone, which is an opioid. It can cause dependence and/or addiction.
Repeated use of opioid pain relievers can result in the drug being less effective (you become accustomed to it, known as tolerance). Repeated use of Oxylan can also lead to dependence, abuse and addiction, which may result in life-threatening overdose.
The risk of these side effects can increase with a higher dose and longer duration of use.
Dependence or addiction can make you feel that you are no longer in control of how much medicine you need to take or how often you need to take it. You might feel that you need to carry on taking your medicine, even when it doesn’t help to relieve your pain.
The risk of becoming dependent or addicted varies from person to person. You may have a greater risk of becoming dependent or addicted on Oxylan if:
- you or anyone in your family have ever abused or been dependent on alcohol, prescription medicines or illegal drugs (“addiction”).
- you are a smoker.
- you have ever had problems with your mood (depression, anxiety or a personality disorder) or have been treated by a psychiatrist for other mental illnesses.
Read more under ‘How do I know if I am addicted?’ in section 4.
Addiction can cause withdrawal symptoms when you stop taking 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 prescriber will discuss with you how to gradually reduce your dose before stopping the medicine. It is important that you do not stop taking 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. Taking 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
Oxylan 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.
Do not use Oxylan for acute post-operative pain because of the increased risk of dependency and developing serious breathing problems.
If you are going to have an operation, or have just had an operation, please tell the doctor at the hospital if you are taking Oxylan. Your doctor may adjust your dose.
Contact your doctor if you experience severe upper abdominal pain possibly radiating to the back, nausea, vomiting or fever as this could be symptoms associated with inflammation of the pancreas (pancreatitis) and the biliary tract system.
Anti-Doping Warning
The use of Oxylan may produce positive results in doping controls.
Use of Oxylan as a doping agent may be a health hazard.
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.
The risk of side effects is increased if you take Oxylan at the same time as medicines which affect the way the brain works. For example, you may feel very sleepy, or breathing problems may get worse.
Medicines that affect the way the brain works include:
- other strong pain relievers (opioids),
- sleeping pills and tranquillisers,
- antidepressants,
- medicines used to treat allergies, travel sickness or nausea (antihistamines or antiemetics),
- other medicines which act on the nervous system (phenothiazines, neuroleptics),
- medicines used to treat Parkinson’s disease (so-called MAO inhibitors, see also section “Warnings and precautions”).
The risk of side effects increases, if you use antidepressants (such as citalopram, duloxetine, escitalopram, fluoxetine, fluvoxamine, paroxetine, sertraline, venlafaxine). These medicines may interact with oxycodone and you may experience symptoms such as involuntary, rhythmic contractions of muscles, including the muscles that control movement of the eye, agitation, excessive sweating, tremor, exaggeration of reflexes, increased muscle tension, body temperature above 38°C. Contact your doctor when experiencing such symptoms.
Concomitant use of Oxylan and sedative medicines such as benzodiazepines or related drugs increases the risk of drowsiness, difficulties in breathing (respiratory depression), coma and may be life-threatening. Because of this, concomitant use should only be considered when other treatment options are not possible. However if your doctor does prescribe Oxylan together with sedative medicines the dose and duration of concomitant treatment should be limited by your doctor.
Please tell your doctor about all sedative medicines you are taking, and follow your doctor’s dose recommendation closely. It could be helpful to inform friends or relatives to be aware of the signs and symptoms stated above. Contact your doctor when experiencing such symptoms.
Further interactions may occur with
- cimetidine (used to manage excess of gastric acid). It may prolong the duration of effects of Oxylan in your body.
- medicines against blood clotting (e.g. warfarin). Oxylan may influence their effects.
- certain antibiotics, antifungal medicines and medicines containing St. John’s Wort.
