When managing moderate to sever pain, patients often ask: what is the difference between Co-codamol vs Dihydrocodeine? Co-Codamol and Dihydrocodeine are two opioid-based painkillers commonly prescribed in the UK, but they differ in composition, potency, and usage. This detailed guide explores their differences, uses, dosages, side effects, and safety considerations, helping you decide which medication suits your pain relief needs best according to NHS and MHRA guidelines.
Co-Codamol is a combination medicine containing two active ingredients: paracetamol (500mg) and codeine phosphate (in strengths such as 8mg, 15mg, or 30mg). It combines the fever-reducing and mild pain relief effects of paracetamol with the stronger opioid pain-relieving action of codeine.
For a detailed guide to Co-codamol, including its uses and safety information, read the full Co-codamol overview here.
Co-Codamol works by paracetamol blocking pain signals and reducing fever while codeine phosphate enhances pain relief through opioid receptor activation, making it effective for moderate pain that is unresponsive to simple analgesics alone.
Dihydrocodeine is a semisynthetic opioid analgesic that is chemically similar to codeine but generally considered 2 to 3 times more potent. It is available both as a single active ingredient and combined with paracetamol (e.g., Co-dydramol). It is used to treat moderate to severe pain, including post-operative and chronic pain. Read our comprehensive guide on how Dihydrocodeine works to manage chronic pain effectively.

Dihydrocodeine binds to opioid receptors with greater potency than codeine, altering pain perception more strongly. When combined with paracetamol, the effect is enhanced similarly to Co-codamol, but with potentially stronger opioid analgesia

| Use Case | Co-codamol | Dihydrocodeine |
|---|---|---|
| Moderate to severe pain | Preferred when paracetamol alone is insufficient | Often used for moderate to severe pain, including chronic pain |
| Post-operative pain | Commonly prescribed | Licensed for moderate to severe pain and chronic severe pain |
| Fever management | Yes, due to paracetamol | No, no antipyretic activity |
| Cough suppression | Not typically used | Occasionally used |
| Medicine | Availability |
|---|---|
| Co-Codamol 8/500mg | Pharmacy sale OTC in limited supply |
| Co-Codamol 15/500mg and 30/500mg | Prescription only |
| Dihydrocodeine | Prescription only, both single and combination forms |
MHRA regulations control opioid medicines to mitigate misuse and addiction, enforcing prescription rules on all but the lowest strength Co-Codamol.
| Patient Condition | Suggested Medicine | Explanation |
|---|---|---|
| Moderate pain needing combined therapy | Co-codamol | Provides balanced analgesia with paracetamol and mild opioid effect |
| More potent opioid for severe pain | Dihydrocodeine | Higher potency opioid suitable for more severe or persistent pain |
| Need to manage fever | Co-codamol | Contains paracetamol, effective for fever control |
| History of liver disease or alcohol use | Medical consultation advised | Paracetamol risks make caution necessary |
| Opioid addiction risk history | Avoid or under specialist supervision | Both contain opioids with addiction risk |

Co-Codamol combines paracetamol and codeine, offering a balanced approach to moderate pain, fever, and inflammation. Dihydrocodeine is a more potent opioid used for moderate to severe pain, often prescribed when less powerful opioids are insufficient. Both are regulated in the UK and require careful use to avoid dependency.
Yes, both medicines can be purchased online from registered UK pharmacies, but prescription is required for higher strengths of both. Always ensure you buy from reputable sources and follow NHS or MHRA guidance to prevent counterfeit products and ensure safe usage.
Typical side effects include constipation, drowsiness, nausea, dizziness, and allergic reactions. Dihydrocodeine, being more potent, may also increase the risk of dependence, especially with prolonged use. Always follow dosing instructions carefully.
Both medicines should be used for the shortest duration necessary. NHS guidelines recommend limiting opioid use to avoid dependence, with Co-Codamol generally advised for up to 3 days unless prescribed otherwise. Dihydrocodeine also requires medical supervision for long-term use
Yes, both Co-Codamol and Dihydrocodeine carry risks of dependence, overdose, and side effects like respiratory depression. Never exceed recommended doses and consult your healthcare provider before use, especially if you have underlying health conditions
Seek medical help immediately if you experience difficulty breathing, severe rash, swelling, or symptoms suggestive of overdose. Always report any side effects to your healthcare professional and follow their instructions for discontinuing or adjusting your medication
