What is Solpadeine? Solpadeine is a brand family and the ingredients and strengths can vary by product and country. Some formulations contain paracetamol with codeine, and some also contain caffeine. Check the exact package rather than assuming all Solpadeine products are equivalent. The opioid-dependence and withdrawal information on this page applies to codeine-containing formulations.

Indications depend on the exact product and country. In the UK, over-the-counter codeine-containing painkillers are labeled for short-term relief of acute moderate pain not relieved by paracetamol, ibuprofen or aspirin alone and for no more than three days. The Irish Solpadeine Tablets leaflet lists the following examples. Follow the locally authorized pack and ask a pharmacist if pain persists:
- Headache, including migraine
- Toothache
- Period pain
- Rheumatic pain
- Backache
- Neuralgia
- Cold and flu symptoms, where included in the locally authorized indication
Availability without a prescription does not mean a medicine is risk-free. Follow the exact pack instructions, check the active ingredients and ask a pharmacist before combining products or if pain persists.
For codeine-containing Solpadeine products, the main safety issues come from codeine, paracetamol and any additional ingredients in the specific formulation. Codeine can cause drowsiness, constipation, nausea, respiratory depression, physical dependence and opioid-use disorder; paracetamol can cause serious liver injury if the recommended total dose is exceeded.
Common effects of codeine-containing products can include:
- drowsiness or dizziness
- nausea or vomiting
- constipation
- increased sedation, impaired alertness and potentially dangerous breathing problems, especially with alcohol or other sedatives
More serious risks depend on the exact formulation. Important examples include:
- slow or difficult breathing, extreme drowsiness or loss of consciousness from codeine toxicity: call emergency services immediately and give naloxone if available according to its instructions
- serious liver injury from excessive paracetamol, including accidental double-dosing with other paracetamol-containing products
- physical dependence and withdrawal after regular codeine use
Paracetamol is present in many combination pain, cold and flu products, so accidental double-dosing can occur when people take more than one paracetamol-containing medicine. The main safety concern is exceeding the recommended total dose, which can cause serious liver injury. Someone who has taken more than the recommended amount should seek urgent poison or medical advice even if they initially feel well, because early symptoms can be mild or absent.
Codeine can cause tolerance and physical dependence during regular use, and some people develop opioid-use disorder. Needing a gradual reduction or experiencing withdrawal does not by itself prove addiction. Concerning signs include loss of control over use, taking more or more often than intended, persistent craving, obtaining extra supplies, or continuing despite clear harm.
Physical dependence, withdrawal and opioid-use disorder need separate assessment:
After regular use of a codeine-containing Solpadeine product, abrupt discontinuation can cause opioid-withdrawal symptoms. Onset and duration vary with dose, duration, formulation and individual factors rather than following a universal timetable. If codeine has been used for more than a short period, discuss an individual reduction plan with the prescriber rather than stopping abruptly.
Possible opioid-withdrawal symptoms from a codeine-containing Solpadeine product include:
- trouble sleeping
- teary eyes
- runny nose
- sweating
- yawning
- loss of appetite
- nausea and vomiting
- stomach cramps
- diarrhea
- feeling irritable or anxious
Withdrawal severity and duration vary. Persistent or worsening symptoms need assessment, and experiencing withdrawal does not mean the person was abusing the medicine.
Products that contain caffeine can also cause restlessness, sleep disturbance, nausea, tremor or a fast heartbeat, especially when combined with substantial caffeine from other sources. Check the ingredients because not every Solpadeine formulation contains caffeine.
Solpadeine and alcohol: risks and side effects
Caffeine can also produce tolerance and physical dependence in regular users. Stopping suddenly may cause headache, fatigue, irritability, low mood or difficulty concentrating. These symptoms are usually self-limited; people who consume substantial caffeine and want to avoid them can reduce intake gradually. Caffeine withdrawal should be kept distinct from opioid withdrawal caused by codeine.
Use the exact formulation only as directed on its label. Do not combine it with another paracetamol-containing product, and avoid alcohol with codeine-containing versions. Seek advice from a pharmacist or clinician if pain persists or if control over use, withdrawal or side effects are a concern. Slow or difficult breathing, inability to wake someone or suspected serious overdose requires immediate emergency help.
