Dihydrocodeine 30mg Dosage Guide (UK)
Dihydrocodeine 30mg is the standard-release strength most commonly prescribed across the UK. This guide covers adult dosing, timing, maximum daily dose, and when to step up to slow release.
Adult dose
- One tablet (30mg) every 4 to 6 hours as needed for pain
- Maximum 180mg in any 24-hour period (i.e. 6 tablets)
- Take with or after food to reduce nausea
- Swallow whole with water; do not crush or chew
Onset and duration
- Onset: 30 to 60 minutes
- Peak effect: around 2 hours
- Duration: 4 to 6 hours
When to take it
Dihydrocodeine 30mg is best for as-needed pain control — a fresh post-op wound, a fracture, a flare of sciatica, severe period pain. If you find yourself needing a tablet every 4 hours around the clock for more than a few days, that’s the moment to consider stepping up to 60mg slow release instead.
Can you take it with paracetamol or ibuprofen?
Yes — both are common, safe UK pairings. See paracetamol with dihydrocodeine and dihydrocodeine and ibuprofen.
What not to combine
- Alcohol (see dihydrocodeine and alcohol)
- Other opioids (codeine, tramadol, morphine)
- Benzodiazepines (diazepam, lorazepam)
- Pregabalin or gabapentin without medical advice
- Sleeping tablets (zopiclone, zolpidem)
All of these combinations increase the risk of dangerous respiratory depression.
Missed dose
If you miss a dose, take it as soon as you remember unless it’s close to your next dose. Never double-dose.
