Codeine Phosphate 15mg Tablets
Codeine Phosphate 15mg tablets remain one of the most widely used prescription pain relief medicines in the UK for short-term management of mild to moderate pain. When standard painkillers such as paracetamol or ibuprofen are not strong enough on their own, Codeine Phosphate provides an effective next-step option. This comprehensive guide is designed to help customers understand the classification, uses, safety information, dosage, and benefits of Codeine Phosphate 15mg tablets, along with guidance on how and where to purchase them in the UK securely.
Codeine Phosphate 15mg Tablets Classification
Codeine Phosphate 15mg tablets are classified as:
- Opioid analgesics – a category of medicines that act on the central nervous system to relieve pain.
- Prescription-only medicine (POM) in the UK – meaning it must be obtained legally from a registered pharmacy following a consultation or valid prescription.
- Controlled drug (Class B) under the Misuse of Drugs Act – due to its potential for dependence or misuse.
- Schedule 5 controlled substance when contained in low-dose combinations – but the 15mg strength is supplied as a standard POM.
This classification ensures the product is regulated, safe to use under medical guidance, and dispensed only by verified UK suppliers. Purchasing from reputable pharmacies ensures authenticity and high-quality standards.
What is Codeine Phosphate 15mg Tablets?
Codeine Phosphate 15mg tablets are an opioid painkiller used to treat:
- Headaches
- Toothache
- Period pain
- Musculoskeletal pain
- Back pain
- Mild injuries
- Postoperative discomfort (short-term only)
The medicine works by altering how your brain and nervous system interpret pain signals. It is commonly used when weaker options like paracetamol do not provide sufficient relief on their own.
Each tablet contains 15mg of the active ingredient Codeine Phosphate, along with pharmaceutical-grade inactive ingredients that support absorption and stability. This dose strikes a balance between effective pain relief and reduced risk of side effects when used responsibly.
Recommended Dosage for Codeine Phosphate 15mg Tablets
Correct dosage is essential to ensure effective pain relief while minimising risk. The recommended dosage for adults and adolescents aged 12 years and over is:
- 1–2 tablets (15–30mg) taken every 4–6 hours as required
- Maximum daily dose: 8 tablets (120mg)
- Do not exceed the stated dose
- Do not use for more than 3 consecutive days without medical advice
Important dosage notes:
- Not suitable for children under 12 years
- For elderly users, dose should be lower or less frequent due to slower metabolism
- Avoid alcohol while taking Codeine
- Always swallow tablets whole with water
- Do not take more frequently than recommended
Following dosage guidelines ensures safe, predictable relief without the risks associated with overuse.
How Does Codeine Phosphate 15mg Tablets Work?
Codeine Phosphate works through its action on the central nervous system (CNS). After ingestion, codeine is converted into morphine by the liver through the CYP2D6 enzyme. The morphine then binds to opioid receptors in the brain and spinal cord to:
- Reduce pain signalling
- Increase pain threshold
- Block the transmission of pain messages
- Induce mild relaxation and calmness
- Provide a soothing analgesic effect
By acting directly on pain pathways, Codeine Phosphate provides more effective relief compared with basic analgesics, especially for deeper, persistent, or moderate levels of pain.
Benefits of Taking Codeine Phosphate 15mg Tablets
Codeine Phosphate offers several benefits for users seeking dependable pain relief:
✔ Fast and Reliable Absorption
The tablets are designed for quick dissolution, bringing relief typically within 30–60 minutes.
✔ Suitable for Moderate Pain
Particularly effective when standard painkillers fail to provide full relief.
✔ Can Be Combined with Other Painkillers
Codeine is often used alongside paracetamol or ibuprofen for stronger pain-relieving effects.
✔ Improves Daily Functionality
Reduces discomfort so users can return to everyday tasks, work, and social activities.
✔ Ideal for Short-Term Use
Highly effective for temporary pain, particularly post-injury or post-treatment.
✔ UK-Regulated Quality
When sourced from reputable UK suppliers, products meet strict manufacturing and safety standards.

What is the Mechanism of Codeine Phosphate 15mg Tablets?
The mechanism of Codeine Phosphate involves a multi-stage process:
- Ingestion – the tablet dissolves in the stomach.
- Absorption – codeine enters the bloodstream.
- Conversion – the liver converts codeine into morphine through the CYP2D6 enzyme.
- Receptor Binding – morphine attaches to mu-opioid receptors in the brain.
- Pain Blockage – the central nervous system reduces pain signal transmission.
- Analgesic Effect – users experience relief, relaxation, and reduced pain sensitivity.
Because codeine works internally on the CNS, it provides steady, dependable pain relief that targets the source of discomfort rather than masking symptoms.
