1. what nexium is and what it is used for

Nexium contains a medicine called esomeprazole. This belongs to a group of medicines called ‘proton pump inhibitors’. They work by reducing the amount of acid that your stomach produces.

Nexium is used to treat the following conditions: Adults

‘Gastroesophageal reflux disease’ (GERD). This is where acid from the stomach escapes into the gullet (the tube which connects your throat to your stomach) causing pain, inflammation and heartburn.
Ulcers in the stomach or upper part of the gut (intestine) that are infected with bacteria called ‘Helicobacter pylori’. If you have this condition, your doctor may also prescribe antibiotics to treat the infection and allow the ulcer to heal.
Stomach ulcers caused by medicines called NSAIDs (Non-Steroidal Anti-Inflammatory Drugs). Nexium can also be used to stop stomach ulcers from forming if you are taking NSAIDs.
Too much acid in the stomach caused by a growth in the pancreas (Zollinger-Ellison syndrome).
Prolonged treatment after prevention of rebleeding of ulcers with intravenous Nexium.

Adolescents aged 12 years and above

‘Gastroesophageal reflux disease’ (GERD).

This is where acid from the stomach escapes into the gullet (the tube which connects your throat to your stomach) causing pain, inflammation and heartburn.

Ulcers in the stomach or upper part of the gut (intestine) that are infected with bacteria called ‘Helicobacter pylori’. If you have this condition, your doctor may also prescribe antibiotics to treat the infection and allow the ulcer to heal.

2. what you need to know before you take nexium

Do not take Nexium:

If you are allergic to esomeprazole or any of the other ingredients of this medicine (listed in Section 6).
If you are allergic to other proton pump inhibitor medicines (e.g. pantoprazole, lansoprazole, rabeprazole, omeprazole).
If you are taking a medicine containing nelfinavir (used to treat HIV infection).

Do not take Nexium if any of the above apply to you. If you are not sure, talk to your doctor or pharmacist before taking Nexium.

Warnings and precautions

Talk to your doctor or pharmacist before taking Nexium:

If you have severe liver problems.
If you have severe kidney problems.
If you have ever had a skin reaction after treatment with a medicine similar to Nexium that reduces stomach acid.
If you are due to have a specific blood test (Chromogranin A).

Nexium may hide the symptoms of other diseases. Therefore, if any of the following happen to you before you start taking Nexium or while you are taking it, talk to your doctor straight away:

You lose a lot of weight for no reason and have problems swallowing.
You get stomach pain or indigestion.
You begin to vomit food or blood.
You pass black stools (blood-stained faeces).

If you have been prescribed Nexium “on demand” you should contact your doctor if your symptoms continue or change in character.

Taking a proton pump inhibitor like Nexium, especially over a period of more than one year, may slightly increase your risk of fracture in the hip, wrist or spine. Tell your doctor if you have osteoporosis or if you are taking corticosteroids (which can increase the risk of osteoporosis).

If you get a rash on your skin, especially in areas exposed to the sun tell your doctor as soon as you can, as you may need to stop your treatment with Nexium. Remember to also mention any other ill-effects like pain in your joints.

The recommended dose is one Nexium 20 mg gastro-resistant tablet twice a day for one week.
Your doctor will also tell you to take antibiotics for example amoxicillin and clarithromycin.

Taking this medicine

You can take your tablets at any time of the day.
You can take your tablets with food or on an empty

stomach.

Swallow your tablets whole with a drink of water. Do not chew or crush the tablets.

This is because the tablets contain coated pellets which stop the medicine from being broken down by the acid in your stomach. It is important not to damage the pellets.

What to do if you have trouble swallowing the tablets

If you have trouble swallowing the tablets:

– Put them into a glass of still (non-fizzy) water.

Do not use any other liquids.

– Stir until the tablets break up (the mixture will not be clear). Then drink the mixture straight away or within 30 minutes. Always stir the mixture just before drinking it.

– To make sure that you have drunk all of the medicine, rinse the glass very well with half a glass of water and drink it. The solid pieces contain the medicine – do not chew or crush them.

If you cannot swallow at all, the tablet can be mixed with some water and put into a syringe.

It can then be given to you through a tube directly into your stomach (‘gastric tube’).

Use in children under the age of 12 years

Nexium gastro-resistant tablets are not recommended for children less than 12 years old. Information on dosing for children aged 1 to 11 years is provided in Nexium sachet product information (ask your doctor or pharmacist if you require further information).

Elderly

Dose adjustment is not required in the elderly.

If you take more Nexium than you should

If you take more Nexium than prescribed by your doctor, talk to your doctor or pharmacist straight away.

If you forget to take Nexium

If you forget to take a dose, take it as soon as you remember it. However, if it is almost time for your next dose, skip the missed dose.
Do not take a double dose (two doses at the same time) to make up for a forgotten dose.

If you have any further questions on the use of this medicine, ask your doctor or pharmacist.

Aggression.
Seeing, feeling or hearing things that are not there (hallucinations).

Not known (frequency cannot be estimated from the available data)

If you are on Nexium for more than three months it is possible that the levels of magnesium in your blood may fall. Low levels of magnesium can be seen as fatigue, involuntary muscle contractions, Disorientation, convulsions, dizziness or increased heart rate. If you get any of these symptoms, please tell your doctor promptly. Low levels of magnesium can also lead to a reduction in potassium or calcium levels in the blood. Your doctor may decide to perform regular blood tests to monitor your levels of magnesium.
Inflammation in the gut (leading to diarrhoea).
Rash, possibly with pain in the joints.

Nexium may in very rare cases affect the white blood cells leading to immune deficiency. If you have an infection with symptoms such as fever with a severely reduced general condition or fever with symptoms of a local infection such as pain in the neck, throat or mouth or difficulties in urinating, you must consult your doctor as soon as possible so that a lack of white blood cells (agranulocytosis) can be ruled out by a blood test.

It is important for you to give information about your medication at this time.
