TENSODOL is a prescription-only combination pain-relief medicine used for the short-term treatment of mild to moderate pain linked to tension and stress. It brings together four different active ingredients, each with a specific role, to ease pain, reduce discomfort, and promote relaxation. Because it contains codeine, an opioid medicine, it must be used carefully and exactly as directed by a healthcare professional.
This medicine is intended for short-term use only. It is not designed for ongoing or long-term pain management unless a doctor specifically advises otherwise.
What it is and what it is used for
What it is
TENSODOL is a combination analgesic (pain-relieving) tablet. Combination medicines work by using more than one active ingredient, each acting in a different way. This can improve pain control compared with using a single ingredient alone.
Each tablet contains:
- Paracetamol
- Codeine phosphate
- Caffeine anhydrous
- Doxylamine succinate
The tablets are sugar-free.
What it is used for
TENSODOL is used to relieve mild to moderate pain associated with tension, including:
- Headaches
- Muscle tension
- General body aches
- Stress-related physical discomfort
It is not suitable for chronic (long-term) pain unless a doctor has specifically prescribed it for that purpose.
How it works
TENSODOL works by combining medicines that support each other to relieve pain more effectively.
- Paracetamol helps reduce pain and fever. It works mainly in the brain to lower pain signals.
- Codeine is a mild opioid. It changes how the body feels and responds to pain, making discomfort easier to tolerate.
- Caffeine acts as a stimulant. In pain medicines, it can enhance the effect of paracetamol, helping it work better.
- Doxylamine is an antihistamine with sedative (calming) effects. It helps reduce tension and can make you feel more relaxed.
Together, these ingredients aim to relieve pain, reduce tension, and promote rest, which can be helpful when pain is linked to stress or muscle tightness.
Who should NOT use this medicine
Do not take TENSODOL if any of the following apply to you:
- You are allergic to paracetamol, codeine, caffeine, doxylamine, or any other ingredient in the tablet
- You have severe liver or kidney disease
- You have breathing difficulties or respiratory depression
- You have had recent bile duct surgery
- You have acute alcoholism
- You have a head injury or raised pressure in the skull

- You are taking monoamine oxidase inhibitors (MAOIs), or have taken them within the last 14 days
- You are known to be an ultra-rapid CYP2D6 metaboliser

If you are unsure whether any of these apply to you, speak to your doctor or pharmacist before taking this medicine.
Warnings and precautions
Important safety warnings
- Do not use for more than 5 days in a row without medical advice.
- Do not combine with other medicines that contain paracetamol or codeine.
- This medicine may cause drowsiness, dizziness, or reduced concentration.
- Do not drive or operate machinery while affected.
- Avoid alcohol, as it increases drowsiness and the risk of serious breathing problems.
- Taking too much paracetamol can cause severe and potentially life-threatening liver damage.
Warning: Paracetamol overdose may not cause immediate severe symptoms but can still result in serious liver injury.
Use with caution
Speak to your doctor before using TENSODOL if you have:
- Liver or kidney problems
- High blood pressure

- Enlarged prostate
- Glaucoma
- Asthma or other breathing conditions

Older adults may be more sensitive to side effects and may need lower doses.
Pregnancy, planning pregnancy, and breastfeeding
Pregnancy
- Paracetamol is generally considered safe when used occasionally during pregnancy.
- Codeine crosses the placenta and regular use may cause dependence in the unborn baby.
- Use during labour may cause breathing problems in newborn babies.
Use of TENSODOL during pregnancy should be avoided unless absolutely necessary and prescribed by a doctor.
Breastfeeding
- Small amounts of paracetamol pass into breast milk.
- Codeine is also excreted into breast milk and may cause opioid toxicity in nursing infants.
TENSODOL should not be used while breastfeeding.
Interactions
TENSODOL can interact with other medicines, which may increase side effects, reduce effectiveness, or cause serious health risks.
Medicines that may interact
- Other paracetamol-containing products: Increased risk of overdose and liver damage

- Antihistamines or antidepressants: Increased dry mouth, constipation, and blurred vision
- Warfarin and other blood thinners: Increased bleeding risk with long-term use
- Diuretics and blood pressure medicines: Increased risk of low blood pressure
- MAOIs (such as phenelzine or tranylcypromine): Severe central nervous system reactions
- Metoclopramide or domperidone: Faster absorption of paracetamol
- Cholestyramine: Reduced absorption of paracetamol
- Anti-seizure medicines (for example phenytoin): Increased risk of liver damage
