Nexium 20mg are in tablet form and a light pink colour. These are gastro resistant tablets and contain a medicine called esomeprazole which works by reducing the amount of acid that your stomach produces. Nexium is used to treat gastro-oesophageal reflux disease (GORD).
Nexium 20mg tablets should always be stored out of sight and reach of children and below 30 degrees Celsius.
Always take Nexium as instructed by your doctor and read the leaflet before taking Nexium. They can be taken at any time of the day either with food or on an empty stomach. They should be swallowed whole with a drink of water and not chewed or crushed. If you are taking this medicine over a long time period (especially over a year) your doctor will monitor you.
If you forget to take a dose at the correct time, take it as soon as you remember it. However, if it is nearly time for your next dose, skip the missed dose and do not take a double dose at the same time.
If you take more tablets than prescribed, talk to your doctor or pharmacist straight away.

Reddening of the skin with blisters or peeling, severe blisters and bleeding in the lips, eyes, mouth, nose and genitals which could be ‘Stevens-Johnson syndrome’ or ‘toxic epidermal necrolysis’.

If you are on Nexium for more than three months it’s possible that the magnesium levels in the blood may fall. This can be seen as fatigue, involuntary muscle contractions, disorientation, convulsions, dizziness or increased heart rate. Low magnesium levels can lead to reduced potassium or calcium levels and your doctor may perform regular blood tests to monitor your levels. Inflammation in the gut which leads to diarrhoea. In very rare cases Nexium may affect the white blood cells leading to immune deficiency which may show with symptoms such as fever with severely reduced general condition or with symptoms of local infection such as pain in the neck, throat or mouth or difficulties in urinating, you must consult your doctor as soon as possible. It is important to give information about your medication at this time.
