CODEINE SIDE EFFECTS, TOLERANCE AND DEPENDENCE When Pain Relief Becomes The Problem The Hidden Truth About Codeine Why Codeine Can Become Harder To Stop Than People Expect Codeine Side Effects Explained: Tolerance, Dependence, Withdrawal, Constipation And Why Pain Can Sometimes Feel Worse Codeine can be an effective painkiller when it is used appropriately. For many people it provides short-term relief after surgery, injury or painful conditions and helps them get moving again. But if you have been taking it for a while, there are some important things worth knowing. Over time, your body can become physically dependent on codeine. That means missing doses may leave you feeling unwell, even if your original pain has not changed. Physical dependence is not the same as addiction. It is a recognised effect of opioid medicines and can happen even when they are taken exactly as prescribed. Possible side effects include: • constipation • nausea • drowsiness • brain fog • poor concentration • dizziness • dry mouth • reduced alertness Some people also notice they need higher doses over time to achieve the same pain relief. This is called tolerance. Another important issue is opioid-induced hyperalgesia. In some people, long-term opioid use may actually make the nervous system more sensitive to pain, meaning the pain feels worse despite continuing treatment. That is one reason why regular medication reviews are so important. Ask your pharmacist, GP or pain specialist: • Is codeine still the best option for my pain? • Am I developing tolerance? • Could my pain be changing? • How can I reduce constipation? • What is the safest plan if I no longer need it? Do not stop codeine suddenly if you have been taking it regularly. Withdrawal symptoms may include: • anxiety • sweating • shaking • restlessness • difficulty sleeping • nausea or diarrhoea • flu-like symptoms • worsening pain Any reduction should usually be planned with your healthcare professional. Take extra care if codeine is combined with sleeping tablets, pregabalin, gabapentin, anxiety medicines, alcohol or other opioid medicines, as these combinations can increase drowsiness and dangerous breathing problems. Seek urgent medical help if someone becomes difficult to wake, has slow or shallow breathing, blue lips, collapses or is difficult to rouse. People often ask: Can you become dependent on codeine? Why do I feel ill if I miss a codeine dose? Does codeine stop working over time? Can codeine make pain worse? How do you stop taking codeine safely? How long is it safe to take codeine? The goal of pain treatment is not simply to take more tablets. It is to improve your quality of life safely while regularly reviewing whether the medicine is still helping more than it is harming. If codeine is helping less than it used to, or you feel worse when you miss it than when you take it, ask for a medication review. That conversation could make all the difference. #codeine #painrelief #opioids #medicationsideeffects #pain @
