What Is Codeine Phosphate 30mg?

Uses of Codeine Phosphate
- Mild to moderate pain — dental pain, post-surgical pain, injury pain
- Dry cough — suppresses the cough reflex in the brain
- Diarrhoea — slows bowel movement to reduce frequency
- Often combined with paracetamol — products like Co-Codamol 30/500mg and Zapain 30/500mg
Dosage
The standard adult dose is 30–60mg every 4 hours, with a maximum of 240mg per day. Codeine should not be used for longer than 3 days for acute pain. In children under 12 it is contraindicated, and in patients who are CYP2D6 ultra-rapid metabolisers it can cause dangerous overdose.
Codeine vs Dihydrocodeine: What Is the Difference?
Dihydrocodeine is approximately twice as potent as codeine at equivalent doses. Codeine is converted to morphine in the body (via CYP2D6), while dihydrocodeine has a more direct analgesic mechanism. If codeine is not providing sufficient pain relief, Dihydrocodeine 30mg or DHC Continus 90mg may be more suitable alternatives.
Side Effects
Common: constipation, nausea, drowsiness, dry mouth. Serious: respiratory depression (particularly at high doses), addiction and dependence with prolonged use. Codeine should not be combined with alcohol or other CNS depressants.
