OxyContin 40mg UK: Uses, Dosage, Side Effects and Safety Information
OxyContin 40mg UK is a prolonged-release formulation of oxycodone, an opioid analgesic used to manage severe pain when opioid treatment is considered appropriate. The prolonged-release formulation releases oxycodone over an extended period, helping provide continuous pain control between doses.
Because oxycodone can cause drowsiness, constipation, tolerance, dependence and potentially serious breathing problems, patients should use OxyContin exactly as prescribed. It should not be shared with another person or taken in a higher amount than prescribed.
What Is OxyContin 40mg?
OxyContin contains oxycodone hydrochloride, an opioid medicine that acts on opioid receptors in the central nervous system. It changes the way the brain and nervous system respond to pain.
The 40mg formulation is a prolonged-release tablet. Unlike immediate-release oxycodone, it releases the active ingredient gradually to provide longer-lasting analgesic effects.
The exact dose a doctor prescribes depends on factors such as the severity of the pain, previous opioid treatment and the patient’s response to treatment.
What Is OxyContin Used For?
Healthcare professionals may prescribe prolonged-release oxycodone for severe pain that requires continuous opioid analgesia.
Treatment may form part of a pain-management plan for conditions associated with persistent severe pain. However, OxyContin is not appropriate for every type of pain.
Your prescriber will consider your medical history, previous opioid exposure and other medicines before deciding whether prolonged-release oxycodone is suitable.
How Does OxyContin Work?
Oxycodone binds to opioid receptors in the brain and central nervous system. Consequently, it changes the perception and emotional response to pain.
OxyContin uses a prolonged-release formulation to deliver oxycodone gradually. This allows the medicine to provide sustained pain relief rather than the shorter action associated with immediate-release formulations.
However, the same opioid action can also affect breathing, alertness and gastrointestinal function. Therefore, careful dosing and medical supervision are important.
OxyContin 40mg Dosage and Administration
Take OxyContin exactly according to your prescription.
The appropriate dose varies between patients. Doctors may consider previous opioid use when determining an appropriate starting dose because people who have not previously taken opioids can have a greater sensitivity to their effects.
For safer use:
- Swallow the prolonged-release tablet whole with water.
- Do not crush, chew or break the tablet.
- Follow the dosing schedule provided by your prescriber.
- Do not take additional doses because your pain has increased.
- Do not give OxyContin to anyone else.
- Speak with your pharmacist if you are unsure what to do after missing a dose.
Importantly, altering a prolonged-release tablet can interfere with its intended release characteristics and may increase the risk of serious adverse effects.

Why Is OxyContin 40mg Different From Immediate-Release Oxycodone?
The main difference is the way the medicine releases oxycodone.
Immediate-release oxycodone releases the active ingredient more quickly, whereas OxyContin uses a prolonged-release formulation for longer-lasting analgesic effects.
As a result, the two formulations should not be treated as interchangeable on a tablet-for-tablet basis. Your prescriber should determine which formulation and strength are appropriate for your treatment.
Possible Side Effects
Like other opioid medicines, OxyContin can cause side effects.
Common effects may include:
- Constipation
- Nausea
- Vomiting
- Drowsiness
- Dizziness
- Headache
- Itching
Some effects may become less troublesome as the body adjusts to treatment. Nevertheless, speak with your doctor or pharmacist if side effects persist or interfere with your normal activities.
Serious Side Effects
Oxycodone can cause serious respiratory depression, particularly when taken at excessive doses or combined with other medicines that suppress the central nervous system.
Seek urgent medical attention if you experience:
- Slow or difficult breathing
- Extreme sleepiness
- Difficulty staying awake
- Loss of consciousness
- Severe confusion
- Symptoms of a serious allergic reaction
The risk of dangerous sedation and breathing problems can increase when opioids are combined with alcohol, benzodiazepines or other medicines that cause central nervous system depression.
For example, patients should tell their healthcare professional if they also use medicines such as diazepam or other sedatives.
OxyContin and Dependence
Regular opioid treatment can result in tolerance and physical dependence. Some patients can also develop opioid use disorder.
Physical dependence means that the body becomes accustomed to the medicine. Consequently, stopping treatment suddenly after regular use can produce withdrawal symptoms.
Possible withdrawal symptoms include:
- Anxiety or restlessness
- Sweating
- Difficulty sleeping
- Muscle aches
- Nausea
- Stomach discomfort
If you have used OxyContin regularly, do not stop treatment suddenly without medical advice. Your prescriber can determine whether a gradual dose reduction is appropriate.
OxyContin and Alcohol
Alcohol can increase the sedative effects of oxycodone. Combining alcohol with OxyContin can therefore increase the risk of excessive sedation and respiratory depression.
Avoid combining opioid medicines with alcohol unless your healthcare professional has specifically advised you otherwise.
OxyContin and Other Medicines
Tell your doctor or pharmacist about all prescription medicines, over-the-counter products and supplements you use.
In particular, discuss the use of:
- Other opioid medicines
- Benzodiazepines
- Sleeping tablets
- Sedating antihistamines
- Medicines that affect the central nervous system
- Alcohol
Combining opioids with benzodiazepines or other sedatives can increase the risk of profound sedation and breathing difficulties.

OxyContin and Driving
OxyContin can cause drowsiness, dizziness and reduced alertness. These effects may make driving or operating machinery unsafe.
Do not drive if you feel sleepy, dizzy, confused or impaired. Your ability to drive may also be affected when treatment begins or when your dose changes.
