• 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.

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.

Serious skin rashes have occurred in patients taking esomeprazole (see also section 4). The rash can involve ulcers of the mouth, throat, nose, genitals and conjunctivitis (red and swollen eyes). These serious skin rashes often come after flu-like symptoms such as fever, headache, body ache. The rash may cover large parts of the body with blistering and peeling of the skin.

If at any time during the treatment (even after several weeks) you develop a rash or any of these skin symptoms, stop taking this medicine and contact your doctor immediately.

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines. This includes medicines that you buy without a prescription. This is because Nexium can affect the way some medicines work and some medicines can have an effect on Nexium.

• If your doctor has found that your food pipe (gullet) has been slightly damaged, the recommended dose is one Nexium 40 mg gastro-resistant tablet once a day for 4 weeks. Your doctor may tell you to take the same dose for a further 4 weeks if your gullet has not yet healed.
• The recommended dose once the gullet has healed is one Nexium 20 mg gastro-resistant tablet once a day.

To treat ulcers caused by Helicobacter pylori infection and to stop them coming back:

• 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.

• 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’).

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).

Dose adjustment is not required in the elderly.

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

• 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.

  These effects are rare, and may affect up to 1 in 1,000 people.

  These effects are rare, and may affect up to 1 in 1,000 people.

There may also be severe blisters and bleeding in the lips, eyes, mouth, nose and genitals. The skin rashes may develop into serious widespread skin damage (peeling of the epidermis and superficial mucous membranes) with life threatening consequences. This could be ‘erythema multiforme’, ‘Stevens-Johnson syndrome’, ‘toxic epidermal necrolysis’ or ‘drug reaction with eosinophilia and systemic symptoms’. These effects are very rare, and might affect up to 1 in 10,000 people.

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.

If you get any side effects, talk to your doctor, pharmacist or nurse. This includes any possible side effects not listed in this leaflet. You can also report side effects directly via the Yellow Card Scheme at www.mhra.gov.uk/yellowcard or search for MHRA Yellow Card in the Google Play or Apple App Store. By reporting side effects you can help provide more information on the safety of this medicine.
