Buy OxyContin OC 40mg in UK Online
OxyContin OC 40mg is a modified-release (prolonged-release) tablet containing 40 mg of oxycodone hydrochloride, a strong opioid analgesic used to treat moderate to severe cancer pain and other severe pain requiring continuous treatment with a strong opioid. The modified-release formulation releases oxycodone gradually over approximately 12 hours, providing long-lasting pain relief.
In the United Kingdom, Oxycontin OC 40mg 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.
What Is OxyContin OC 40mg?
Each prolonged-release tablet contains:
- Active ingredient: Oxycodone hydrochloride 40 mg
- Medicine class: Strong opioid analgesic
- Dosage form: Modified-release (extended-release) tablet
According to the UK Summary of Product Characteristics, the 40 mg tablet is yellow, round, convex, and marked “OC” on one side and “40” on the other.
How Does Oxycontin OC 40mg Work?
Oxycontin OC 40mg binds to mu-opioid receptors in the brain and spinal cord. This action:
- Reduces the perception of pain
- Alters the emotional response to pain
- Provides sustained pain relief for approximately 12 hours
Because oxycodone also suppresses the brain’s respiratory centre, it can slow breathing, particularly at higher doses or when combined with alcohol or other sedating medicines.
Medical Uses
Healthcare professionals may prescribe OxyContin OC 40 mg for:
- Severe chronic pain
- Cancer-related pain
- Pain associated with advanced illnesses
- Severe pain requiring continuous opioid therapy
OxyContin prolonged-release tablets are not intended for breakthrough pain or occasional (“as needed”) pain relief. They are usually taken every 12 hours as prescribed.
Availability in the UK
OxyContin 40mg is available only with a valid prescription.
Because it is a Schedule 2 Controlled Drug:
- Prescriptions must meet strict legal requirements.
- Treatment should be reviewed regularly.
- The medicine should only be used by the person for whom it was prescribed.
Dosage
The correct dose depends on:
- Severity of pain
- Previous opioid use
- Age
- Liver and kidney function
- Other medical conditions
- Other medicines being taken
OxyContin 40mg is a high-strength tablet and is generally intended for patients who are already tolerant to opioid medicines. It is not recommended as a starting dose for opioid-naïve patients. The manufacturer’s prescribing information recommends starting opioid-naïve adults on lower strengths, with careful dose adjustment based on pain control and tolerability.
Important:
- Take the medicine exactly as prescribed.
- Swallow the tablets whole with water.
- Do not crush, chew, split, or dissolve the tablets, as this can release a potentially dangerous amount of oxycodone rapidly and significantly increase the risk of overdose.
Benefits of Oxycontin OC 40mg

Dependence, Tolerance, and Addiction
Long-term oxycodone treatment can lead to:

Tell your healthcare professional about all medicines, vitamins, and herbal supplements you take.
Important interactions include:
- Other opioid medicines
- Benzodiazepines

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

Alcohol can:
- Increase drowsiness
- Slow breathing

Driving and Operating Machinery
