The active ingredient in Nurofen: Ibuprofen
When the body picks up an infection, sustains an injury, or has both, the inflammatory response kicks in. The inflammatory response produces chemicals called prostaglandins, which can make nearby nerves sensitive to pain. The pain response is important, as it helps our bodies realise that something is wrong. While this response may serve as a warning system, it can also make tissues inflamed, swollen and painful. Prostaglandins are one of the reasons why you may feel a sore throat when sick, or experience swelling with a sprained ankle. Nurofen’s main active ingredient is ibuprofen, which is a non-steroidal anti-inflammatory drug (NSAID) – also called an anti-inflammatory. Ibuprofen helps relieve pain and inflammation by blocking prostaglandin production. Interestingly, not all pain relievers work in the same way. For instance, paracetamol which is a different pain reliever, is understood to help relieve pain by interrupting pain signals in the brain (central nervous system).
How Nurofen helps relieve fever
Fever or ‘having a high temperature’ is when the core temperature in our body rises higher than normal. You probably have a fever if your temperature is 38°C or higher. Some of the effects associated with fever can include sweating, shivering, chills or aching muscles and joints. Whilst fever is commonly brought upon by infection, it can also occur for other reasons, such as underlying medical conditions. Fever is triggered when the immune system signals the brain, or more specifically the hypothalamus, which is our temperature control centre in the brain. Our hypothalamus is a bit like the body’s thermostat, controlling heat production and heat loss to maintain the ‘normal’ body temperature. In the case of fever, the immune system triggers the production of chemicals, including prostaglandins, which then raise the set point of the hypothalamus, resulting in an increase in body temperature. Nurofen can help reduce fever as ibuprofen blocks prostaglandin production. If you or a family member is experiencing fever, you should consult your doctor or pharmacist for treatment advice.
