Co-codamol is a widely used combination painkiller in the UK. There is often confusion about whether it requires a prescription and whether it can be bought online.
What Is Co-Codamol?
Co-codamol is a combination medicine containing codeine phosphate and paracetamol. It is used for the relief of moderate to moderately-severe pain.
What Are the Different Strengths?
- Co-codamol 8/500mg – available over the counter (OTC) in limited quantities
- Co-codamol 15/500mg – prescription-only
- Co-codamol 30/500mg – prescription-only, for moderate to severe pain
Can You Buy Co-Codamol Online Without a Prescription?
The 8/500mg strength can be purchased OTC in pharmacies in limited quantities. The 15/500mg and 30/500mg strengths are prescription-only and cannot be legally purchased without a prescription or clinical consultation from a regulated UK pharmacy.
Codeine Safety and Dependence
Codeine is an opioid and carries a genuine dependence risk with prolonged use. It should be used at the lowest effective dose for the shortest necessary duration. Never exceed the stated dose as paracetamol overdose can cause fatal liver damage.
Frequently Asked Questions
Is Co-codamol stronger than ibuprofen?
For many types of pain, Co-codamol 30/500mg is more effective than ibuprofen alone. However, ibuprofen has anti-inflammatory properties that Co-codamol lacks.
How long does Co-codamol take to work?
Co-codamol typically starts working within 30-60 minutes. Peak pain relief is usually within 1-2 hours.
