Treating chronic pain is complex. Treatment usually won’t make the pain go away. Instead, the aim of treatment is to find ways to reduce the impact pain has on your life.
Commonly used pain relief medicines are a useful option for treating short-term (acute) pain, but they are not very effective in treating chronic pain and when used long term, can have more side effects. However, there are some medicines that can be used alongside physiotherapy, exercise, balanced diet, relaxation and different ways of thinking and responding to pain.

If you are using medicines for chronic pain, it is a good idea to develop a pain management plan with your doctor, which can be discussed and then written down. This plan should provide you with clear guidance on how to use your medicines correctly, including:
- the dose and how often to take them
- when or if you can increase the dose
- common side effects
- how to reduce the dose and stop medicines as your pain improves.
It should also include a review schedule, such as seeing the doctor again within 2 to 4 weeks of starting a medicine or changing a dose, to see if you have any side effects and assess how well your pain is controlled.
