Buy OxyContin OC 5mg in UK Online
OxyContin OC 5mg is a modified-release (prolonged-release) tablet containing 5 mg of oxycodone hydrochloride, a strong opioid pain medicine used to treat moderate to severe pain in patients with cancer and other severe pain that requires continuous opioid treatment. The tablet releases the medicine gradually over approximately 12 hours to provide sustained pain relief.
In the United Kingdom, OxyContin is a Prescription Only Medicine (POM) and a Schedule 2 Controlled Drug. It is available only with a valid prescription because of the risks of respiratory depression, overdose, physical dependence, and opioid use disorder (addiction).
What Is OxyContin OC 5mg?
Each prolonged-release tablet contains:
- Active ingredient: Oxycodone hydrochloride 5 mg
- Medicine class: Strong opioid analgesic
- Dosage form: Modified-release (extended-release) tablet
According to the UK prescribing information, the 5 mg tablet is light blue, round, convex, and marked “OC” on one side and “5” on the other.
How Does Oxycontin OC 5mg Work?
Oxycontin OC 5mg binds to mu-opioid receptors in the brain and spinal cord. This helps:
- Reduce the perception of pain
- Alter the emotional response to pain
- Provide prolonged pain relief for about 12 hours
Like all opioids, oxycodone can also slow breathing, particularly if taken in excessive doses or together with alcohol or other medicines that cause drowsiness.
Medical Uses
Healthcare professionals may prescribe OxyContin OC 5 mg for:
- Moderate to severe cancer pain
- Severe chronic pain requiring continuous opioid treatment
- Pain associated with advanced illnesses
Oxycontin OC 5mg prolonged-release tablets are not intended for occasional (“as needed”) or breakthrough pain. They are designed to be taken on a regular schedule, usually every 12 hours.
Availability in the UK
OxyContin 5mg is available only with a valid prescription.
As a Schedule 2 Controlled Drug:
- Prescriptions must meet strict legal requirements.
- Patients should be reviewed regularly during treatment.
- The medicine should never be shared with another person.
Dosage
The correct dose depends on:
- The severity of pain
- Previous opioid use
- Age
- Kidney and liver function
- Other medical conditions
- Other medicines being taken
For some adults who have not previously taken strong opioids, a healthcare professional may start treatment with 5 mg every 12 hours to reduce the likelihood of side effects, although 10 mg every 12 hours is the usual starting dose for many opioid-naïve adults. The dose is then adjusted according to pain control and tolerability.
Important instructions:
- Take the medicine exactly as prescribed.
- Swallow the tablet whole with water.
- Do not crush, chew, split, or dissolve the tablet, as this can rapidly release the full dose and significantly increase the risk of a life-threatening overdose.

These symptoms may indicate an opioid overdose or another medical emergency.
Dependence, Tolerance, and Addiction
Long-term treatment with oxycodone can lead to:

- Opioid use disorder (addiction)

Drug Interactions
Tell your healthcare professional about all medicines and supplements you take.
Important interactions include:
- Other opioid medicines
- Benzodiazepines
- Sleeping tablets
- Alcohol

These combinations can greatly increase the risk of excessive sedation, respiratory depression, coma, and overdose.

Alcohol increases the risk of:
- Excessive drowsiness
- Respiratory depression
- Overdose
- Fatal complications
Driving and Operating Machinery
Oxycodone may impair your ability to:

Do not drive if you feel sleepy, dizzy, or unable to concentrate safely. Follow UK legal guidance regarding driving while taking opioid medicines.
Pregnancy and Breastfeeding
If you are pregnant, planning a pregnancy, or breastfeeding, speak with your healthcare professional before taking oxycodone.
Long-term opioid use during pregnancy may lead to neonatal opioid withdrawal syndrome, requiring specialist care after birth.
