What Is Longtec Oxycodone 30MG?
Longtec is a brand of slow-release oxycodone, a strong prescription opioid used to manage moderate to severe pain that doesn’t respond to weaker painkillers. The 30MG dose is typically reserved for long-term pain management in opioid-tolerant patients, especially those with chronic conditions like cancer, severe arthritis, or post-surgical pain.
It’s not a quick fix—it’s a controlled-release tablet designed to provide steady pain relief over 12 hours, helping people regain control over their daily lives.

How Longtec Works in the Body
Oxycodone is an opioid analgesic, meaning it binds to opioid receptors in the brain and spinal cord. These receptors block pain signals, creating a calming, numbing effect. Longtec releases the medicine slowly into the bloodstream, maintaining consistent pain control without the peaks and crashes seen with short-acting meds.
Why Is Longtec Prescribed?
- Long-term cancer pain
- Chronic lower back or nerve pain
- Pain from injury or trauma
- Post-surgical recovery
- Severe osteoarthritis or joint degeneration
It’s typically used when other painkillers (like codeine, tramadol, or NSAIDs) fail to provide adequate relief.
What Makes the 30MG Dose Significant?
30MG is a higher-strength formulation, only prescribed to those who are already familiar with opioid use. Starting at this dose without tolerance could result in overdose or severe side effects. Doctors usually build patients up to 30MG over time, after trying lower doses like 5MG or 10MG.
How to Take Longtec Oxycodone 30MG
- Take exactly as prescribed—never crush or chew the tablet
- Swallow whole with water
- Taken every 12 hours, at the same time each day
- Can be taken with or without food
- Do not increase your dose unless advised by your doctor
Because Longtec is extended-release, messing with the tablet can release too much oxycodone at once—which is extremely dangerous.
What Does Longtec Feel Like?
When taken properly, Longtec 30MG provides steady, background relief from persistent pain. You may feel:
- Less aching or stiffness
- Improved ability to move or sleep
- A general sense of calm or relaxation
- Mild drowsiness in some cases
It’s not meant to cause a “high”, and if used recreationally or at high doses, it can become dangerous very quickly.
How Long Does It Take to Work?
Longtec starts working within 1 to 2 hours, with pain relief lasting up to 12 hours. It should be taken consistently to keep pain levels controlled—not just when pain flares up.
Common Side Effects of Longtec
Like all opioids, Longtec 30MG comes with side effects—some of which may lessen over time as your body adjusts:
- Constipation (very common)
- Drowsiness or fatigue
- Dry mouth
- Nausea or vomiting
- Itching or mild skin rash
- Sweating
- Light-headedness
To manage constipation, it’s recommended to take a daily laxative or stool softener while on long-term opioids.
Serious Risks and Warnings
- Respiratory depression (slowed or shallow breathing)
- Dependence and withdrawal
- Overdose risk—especially if mixed with alcohol or other sedatives
- Dizziness and falls—especially in older adults
If you notice confusion, extreme drowsiness, slowed breathing, or loss of consciousness—seek emergency help immediately.
Is Longtec Addictive?
Yes, like all opioids, Longtec carries a risk of dependence. The longer and higher the dose you use, the greater the chance. However, when taken exactly as prescribed under medical supervision, addiction is less likely—especially when used for legitimate, persistent pain.
What Happens If You Miss a Dose?
Take your next dose as soon as you remember—but skip it if your next dose is less than 4 hours away. Never double up. If you miss more than one dose in a row, consult your doctor before restarting.
Can You Stop Longtec Suddenly?
No. Stopping cold turkey can lead to withdrawal symptoms like:
- Muscle aches
- Irritability or restlessness
- Insomnia
- Nausea or diarrhea
- Sweating or chills
Your doctor will help you taper down gradually to avoid uncomfortable withdrawal.
Is Longtec Legal in the UK?
Yes. Longtec is a Class A controlled substance, available only by prescription. It must be stored securely, and it’s illegal to share, sell, or possess without proper medical documentation. Pharmacies in the UK follow strict rules when dispensing it.
Can You Drive While on Longtec?
Legally, you must not drive if the medication impairs your ability to operate a vehicle safely. While many people develop tolerance to drowsiness, you should avoid driving until you know how Longtec affects you.
How long does Longtec 30MG last?
Each tablet is designed to provide steady pain relief for up to 12 hours, meaning it’s usually taken twice daily.
Can I take other painkillers with Longtec?
Yes, but only with a doctor’s approval. Paracetamol and ibuprofen may be allowed, but mixing opioids with other sedatives or alcohol is dangerous.
Is Longtec stronger than morphine?
Milligram-for-milligram, oxycodone is stronger than morphine in most patients. However, effects vary depending on metabolism and history of use.
What if Longtec isn’t controlling my pain?
Never increase the dose on your own. Speak to your doctor—they may adjust your medication, switch to another opioid, or add supportive therapy.
What should I do with leftover Longtec tablets?
Don’t keep them. Unused opioids should be returned to your pharmacy for safe disposal. Keeping them at home increases the risk of misuse or accidental poisoning.
