What is a Painkiller?

The type of medicines that you need to treat your pain depend on what type of pain you have. For pain associated with inflammation, such as back pain or headaches, paracetamol and anti-inflammatory painkillers work best. If the pain is caused by sensitive or damaged nerves, as is the case with shingles or sciatica, it's usually treated with tablets that change the way the central nervous system works. The aim of taking medication is to improve your quality of life. All painkillers have potential side effects, so you need to weigh up the advantages of taking them against the disadvantages.

How do painkillers work?

 NSAIDs work by blocking (inhibiting) the effect of chemicals (enzymes) called cyclo-oxygenase (COX) enzymes. COX enzymes help to make other chemicals called prostaglandins. Some prostaglandins are involved in the production of pain and inflammation at sites of injury or damage. A reduction in prostaglandin production reduces both pain and inflammation. Not all NSAIDs are exactly the same, and some work in slightly different ways from others. See the separate leaflet called Anti-inflammatory Painkillers for more details. Paracetamol - no one really knows for sure exactly how paracetamol works. But it is also thought to work by blocking COX enzymes in the brain and spinal cord (central nervous system). Paracetamol is used to treat pain and to lower a high temperature. However, it does not help with inflammation. Opioids work by binding to certain receptors (opioid receptors) in your central nervous system, your gut and other parts of your body. This leads to a decrease in the way you feel pain and your reaction to pain, and it increases your tolerance for pain. See the separate leaflet called Strong Painkillers (Opioids) for more details.

Which painkiller is usually prescribed?

The type of painkiller your doctor will prescribe depends upon:

  • The type of pain you have.
  • Any other health problems you may have.
  • How severe your pain is.
  • The possible side-effects of the medicines.

Paracetamol is normally prescribed if your pain is not too serious and you do not have inflammation. NSAIDs are generally prescribed for people who have pain and inflammation - for example, if you have pain in your joints (arthritis) or muscles (back pain). This is because there is likely to be some inflammation present and NSAIDs work well to treat pain as well as inflammation. NSAIDs have a number of possible side-effects and they are not suitable for everyone. For example, they are not suitable for people who have or have had stomach ulcers. In this case a doctor may prescribe a safer medicine (paracetamol) even though it may not work as well. NSAIDs can be used with heat and ice treatment in joint, muscle or ligament injuries. See the separate leaflet called Heat and Ice Treatment for Pain. Weak opioids are usually prescribed for more severe pain, or if you have tried paracetamol and/or ibuprofen and they have not worked. Stronger opioids are normally used to treat severe pain - for example, cancer-related pain, pain after an operation, or if you have had a serious injury. Anti-inflammatory medicines used as a cream (topical painkillers) are mainly used to treat pain in your soft tissues and muscles. See the separate leaflet called Topical Anti-inflammatory Painkillers for more details.

How should I take painkillers?

People who are in pain all the time are usually recommended to take painkillers regularly. For example, if you have been prescribed paracetamol you will normally take it four times a day, every day until the pain is better. Otherwise, you only need to take painkillers when you need them. If you are taking an NSAID such as ibuprofen or diclofenac, you will need to take this with or after food. This is because they can irritate the lining of your stomach and sometimes cause bleeding in your stomach.
