Codeine addiction is a form of opioid dependence where a person becomes physically or psychologically reliant on codeine, often without realising it at first. It usually starts with repeated use of codeine for pain, illness or discomfort, before gradually becoming harder to control or stop.
Codeine is commonly prescribed by GPs and is also found in some over-the-counter medicines, which can make it feel low-risk. Because of this, many people continue using codeine for longer than intended and only recognise a problem once their body begins to rely on it to function normally.
Codeine is an opioid medication used to treat mild to moderate pain and, in some cases, coughs. It is often combined with other medicines such as paracetamol or ibuprofen and prescribed for short-term use.
Because codeine is medically approved and widely used, many people assume it is safe to take for long periods. However, like all opioids, codeine affects the brain’s reward and pain systems. With repeated use, the body can begin to rely on it, increasing the risk of dependence.
Codeine addiction usually starts with regular use over time, rather than misuse from the beginning. Many people take codeine as prescribed but continue using it for weeks or months longer than intended.
As tolerance builds, the original dose may stop working as well, leading some people to take more or use it more often. Others may begin using codeine not just for pain, but to feel relaxed, calm or emotionally settled. These changes often happen slowly, making them easy to miss.
Signs of codeine dependence often develop gradually and may not be obvious at first.
Common signs can include:
Needing higher doses of codeine to get the same effect
Feeling unwell, anxious or uncomfortable when codeine is missed
Worrying about running out of codeine or planning use in advance
Finding it difficult to reduce or stop using codeine
Experiencing withdrawal symptoms such as restlessness, low mood, flu-like symptoms or sleep problems
These signs do not mean someone has failed. They indicate that the body has adapted to codeine and may need support to adjust safely.
Someone should consider getting help if they feel unable to stop using codeine, are taking it for longer than planned, or are using it to cope with daily life rather than pain alone.
Support can help manage withdrawal safely and address the reasons codeine use continued. Many people find that early help prevents the problem from becoming more severe and reduces the stress of trying to stop alone.
Codeine addiction is a common and often overlooked problem in the UK because the drug is widely available and medically prescribed. Dependence usually starts gradually and can develop even when codeine is taken as directed.
If codeine feels hard to stop or has become something you rely on, support is available. Getting help is a practical step and does not mean you have done anything wrong.
