Details

What is it used for?

  • Relief from the symptoms of colds and flu at night, including tickly, unproductive coughs, runny nose, fever, headache, aches and pains and sore throats.

How does it work?

Night nurse capsules and liquid contain three active ingredients, paracetamol, promethazine and dextromethorphan.

Paracetamol is a simple painkilling medicine used to relieve mild to moderate pain and fever. Despite its widespread use for over 100 years, we still don't fully understand how paracetamol works to relieve pain and reduce fever. However, it is now thought that it works by reducing the production of prostaglandins in the brain and spinal cord.

The body produces prostaglandins in response to injury and certain diseases. One of the effects of prostaglandins is to sensitise nerve endings, causing pain (presumably to prevent us from causing further harm to the area). As paracetamol reduces the production of these nerve sensitising prostaglandins it is thought it may increase our pain threshold, so that although the cause of the pain remains, we can feel it less.

It is thought paracetamol reduces fever by affecting an area of the brain that regulates our body temperature (the hypothalamic heat-regulating center). The paracetamol in night nurse helps relieve aches, pains, sore throats and fever associated with colds and flu.

Dextromethorphan is a type of medicine called a cough suppressant. It is used to suppress a dry, tickly, unproductive cough. It works by reducing the nerve signals sent from a part of the brain called the coughing centre to the muscles that produce coughing.

Coughing is a reflex response to irritation of the airways. It is useful for clearing mucus, dust and other particles from the throat and lungs. It is important because it reduces the amount of mucus, dust and bacteria in the airways that would otherwise make breathing difficult. However, sometimes coughing can become overstimulated even when there is no mucus to clear from the lungs or throat. In this situation coughing serves no purpose and can become painful and frustrating. Dextromethorphan can be used to block the cough reflex in situations where the cough serves no purpose, ie when no plegm is being coughed up.

Promethazine is a type of medicine called a sedating antihistamine. It enters the brain in sufficient quantities to cause drowsiness, and this sedative effect may also help suppress a cough.

Nasal mucus can often be the cause of cough in a cold, because it drips down the back of the throat, causing irritation. Promethazine also drys nasal secretions, by stopping a natural body chemical called histamine from binding to its receptors. Histamine is a chemical produced naturally by the body that has many effects, including the production of allergic symptoms, such as a runny nose. Blocking histamine receptors prevents the actions of histamine, which reduces the production of mucus in the nose.

The combination of active ingredients in this medicine helps relieve aches, pains and fever, as well as a runny nose and tickly coughs associated with colds and flu. The medicine has a mild sedative effect and this, together with the relief from symptoms, can help restful sleep.
