Codeine addiction: signs, withdrawal & UK treatment
Codeine is Britain's most common over-the-counter opioid dependence. Products like Nurofen Plus, Solpadeine and co-codamol are widely available and easy to escalate on. Long-term use adds paracetamol or ibuprofen overdose to the opioid problem.
Signs of codeine addiction
- Buying codeine products from multiple pharmacies to avoid limits
- Taking more than the pack instructions
- Withdrawal — sweating, cramps, low mood — if a dose is missed
- Using codeine for anything other than short-term pain
- Hiding purchases from family
Getting treatment
Mild-to-moderate codeine dependence often responds to a supervised outpatient taper. Heavier users, or those on high-strength co-codamol, may need short inpatient detox — often with buprenorphine for a few days.

Common questions
Is over-the-counter codeine addictive?▾
Yes. UK OTC codeine products are limited to 3-day sales for exactly this reason. Daily use for more than a few weeks routinely produces physical dependence.
How do I safely stop codeine?▾
Talk to your GP or a private clinic. A supervised outpatient taper works for most people. Sudden stopping is uncomfortable but not usually dangerous — a taper is much kinder.
What about the paracetamol in co-codamol?▾
This is the bigger long-term risk. Chronic high-dose paracetamol from co-codamol causes liver damage; ibuprofen from Nurofen Plus causes stomach bleeds and kidney damage. Any dependence on these needs an honest GP conversation.
