Oxycodone long-acting (modified release) tablets
Other names – Oxycontin®, Longtec® tablets
Who is the leaflet for? What is its aim?
This leaflet is for patients who have been discharged from hospital with long-acting oxycodone for moderate to severe pain, and where appropriate their relatives or carers. The need for long-acting oxycodone will have been explained to you before you leave hospital. Do not hesitate to ask for more information or to have it repeated, if needed.
Long-acting oxycodone (also known as modified release) is a strong painkiller from the same family of drugs as morphine. It works in a similar way to morphine. Long-acting oxycodone is commonly used for moderate to severe pain from many different causes. It can be used on its own, with short-acting oxycodone, or with other types of medicines to treat pain. These medications are safe and usually effective for controlling pain when used properly at the dose recommended for you.
Managing your pain may be an ongoing process and health professionals will work with you to adjust the medication doses as needed. Health professionals (including doctors, nurses, pharmacists and opticians) will need to know that you are taking these medications, so do inform them, even if you are seeing them for an unrelated matter.
Benefits
The medication you have been prescribed will help to manage your pain, enabling you to be more comfortable and active at home. Long-acting oxycodone should be taken 12 hours apart and should give pain relief for 12 hours.
How to take long-acting oxycodone
Long-acting oxycodone is taken twice daily. We recommend you take the first dose when you wake up and the second dose 12 hours later, for example at 7 o’clock in the morning and 7 o’clock in the evening.
If you miss a dose, take the next dose as soon as you remember, provided this is within four hours of the time you would normally take the medicine. Take your next dose at the normal time.
Do not take a double dose. If you vomit and bring up the medicine, take another dose as soon as you feel better, providing it is less than four hours since you last took a dose. If this happens again, tell your doctor or nurse. If it is more than four hours since you would have taken your tablet, please contact your doctor, nurse or pharmacist for advice.
You must swallow your long-acting oxycodone whole i.e. without breaking or crushing the tablet. If you take a tablet that is broken, crushed or chewed, the dose intended to be given over 12 hours will be absorbed more rapidly and can lead to breathing difficulty and overdose. Avoid alcohol within one hour of taking your long-acting oxycodone.
You will also be given a short-acting oxycodone, usually this is a liquid. If you get (breakthrough) pain between doses of long-acting oxycodone, you can take a dose of the short-acting oxycodone. Allow approximately 30 minutes for a dose of short-acting oxycodone to take effect. If you find that you are regularly needing to take more than two or three (breakthrough) doses a day, tell your doctor or nurse as your long-acting oxycodone dose may need adjusting.
Side effects
Long-acting oxycodone may cause you to feel sick (nausea) or to vomit when you start taking it. Taking the medicine with food may help. It is possible that you will have been given an anti-sickness medication (anti-emetic) to take regularly when the painkiller is started. For most patients, symptoms of nausea fade within a few days as the body gets used to the new drug over two to three days. If they persist or are not controlled by anti-sickness medication, please speak to your doctor or nurse as alternatives that may suit you better are available.
Long-acting oxycodone may increase the risk of constipation and you may have been prescribed a laxative to take regularly. Maintaining a good fluid intake, being active and having fibre in your diet will also help.
Feeling more sleepy than normal is common in the first few days of taking long-acting oxycodone or after an increase in the dose taken. This will usually resolve over a few days whilst your body is getting used to the new medication, or higher dose. Please avoid driving and operating machinery if you are affected. If this sleepy feeling does not improve after a few days, or it stops you from being able to read a newspaper, or follow the plot of a television programme, then please seek medical advice promptly. It may be best to avoid alcohol whilst taking oxycodone as you are more likely to get side effects, such as feeling sleepy.
If you have a history of lung disease (such as COPD or lung fibrosis) or are known to have a blockage in your airway which affects your breathing, then oxycodone may cause you to breathe less deeply which could be dangerous if not monitored. In these conditions or if you are concerned about your breathing, please check that your doctor or nurse who is prescribing oxycodone to you is aware of your condition and they are satisfied that oxycodone is safe.
These medications can be dangerous if they are taken by those they are not prescribed for. Please keep them out of the reach of children or anyone else who might take them inadvertently. If this happens seek medical advice immediately. They should be stored in the original container to protect from light and below 25°C.
Common questions asked about oxycodone
No. Oxycodone is given for different sorts of moderate and severe pain. If you have cancer, treatment with oxycodone may be needed to allow you to live as comfortably as possible. Oxycodone can be taken for as long as it’s needed and the dose can be changed over time.
Addiction is very rare when oxycodone is used for pain relief, under the guidance of your doctor or nurse. If you no longer require oxycodone, the dose can be gradually and safely reduced by your doctor or nurse.
Oxycodone should not be stopped abruptly.
Some people find that doing certain activities, such as having a bath or going for a walk, bring on the pain. Your doctor or nurse may suggest that you try taking a dose of short-acting oxycodone 30 minutes before starting an activity that brings on the pain.
Although oxycodone is a very good pain killer, it is not helpful for all types of pain and may require adjustments by your doctor or nurse. Sometimes other treatments are be needed and suggested by your medical team.
If you still have pain and feel unwell in one or more of the following ways:
- Feeling more sleepy than usual
- Feeling sick more of the time
- Feeling restless or jumpy
- Experiencing dreams that are more vivid than usual or seem real
tell your doctor or nurse. It may be necessary to reduce your dose of oxycodone or suggest other treatments to help the pain.
Once you get used to taking oxycodone and do not feel sleepy or unwell, you may be able to drive. You must not drive if you feel that your driving may be impaired, in line with the Driving whilst impaired by a drug legislation. In 2015, the government introduced new legislation Driving under the influence of drugs. The Department for Transport advises patients to carry evidence that you have been prescribed oxycodone by a doctor in case you are stopped by the Police. We advise anyone who is unsure about the effects of their medication, or how the 2015 legislation may affect them, to seek the advice of their doctor, nurse or pharmacist.
If you feel sleepy with oxycodone or are required to drive, it is advisable to limit or avoid alcohol consumption whilst taking oxycodone. In general, alcohol is more likely to make side effects from taking oxycodone more likely to happen or more pronounced in their effect such as increased feeling of being sleepy, tired or sick.
Tablets or liquids which are no longer needed, or past their expiry date, should be returned to a pharmacy.
Alternatives
The team looking after you will continue to manage your pain as well as possible, using a combination of drug and non-drug treatments. If your pain continues despite these treatments, please inform your medical team who will explore this further and consider alternative options. Being completely pain-free is not always possible, but bringing your pain into comfortable levels is the main priority of all treatments. While you are awaiting advice do not alter the amount of your medication that you are taking or stop taking it suddenly.
Contacts and further information
Once you are discharged, your GP or community specialist palliative care nurse will provide support to help you manage your pain and to help you use the long-acting oxycodone as effectively as possible.
