Pain Killers

The range of painkillers (analgesics) available is very large and can be confusing. However, there are a limited number of ingredients and this information is designed to help you choose the right product for your type of pain.

Generally, products containing paracetamol, aspirin or ibuprofen alone will be useful to treat mild to moderate pain. One or more of these plus either codeine or dihydrocodeine will treat more severe pain.

Aspirin and ibuprofen are both anti-inflammatory. This means they will help to reduce the inflammation, which may be causing the pain. This makes them particularly suitable for joint pain, muscle strains and sprains and toothache. Paracetamol is not an anti-inflammatory.

Paracetamol, aspirin and ibuprofen are all anti-pyretic. This means that they will help to reduce a raised body temperature (fever) caused by an infection.

Analgesics come in many different forms. Soluble tablets are absorbed by the body more quickly than solid tablets and so will start to reduce the pain more quickly. There are other fast acting products such as Nurofen Advance. Sustained release products have longer lasting painkilling effects and so are more suitable for long lasting pain. Capsules and caplets tend to be easier to swallow than traditional round tablets. Flavoured liquids are available for children.

There are various possible side effects with these common painkillers, and certain groups of people should avoid taking some of them, or should consult a pharmacist or doctor before taking them. Brief descriptions are given in the table below, however please check individual product details, or ask our pharmacists for more advice.

There are specialist products available for treating migraine and period pain.

Other
ingre-
dients
Caffeine This is a weak stimulant and is often included as an ingredient in painkilling products. It is believed to increase the painkilling effects of the other ingredients.
Diphen-
hydramine
This is a mild antihistamine which is included as an extra ingredient in some painkillers, as it causes drowsiness and can help to promote
sleep in those suffering from night-time pain.
Doxy-lamine Doxylamine is also a drowsy antihistamine, which is included in Syndol tablets for its muscle relaxant properties. This preparation is therefore particularly suitable for tension headaches that require a stronger painkiller than standard paracetamol or aspirin tablets.
Methionine Is an ingredient of Paradote. It has no analgesic effect of its own but may reduce damage to the liver by paracetamol if an overdose is taken.
