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 and young people aged 12 years and above
 ‘Gastro-oesophageal reflux disease’ (GORD). 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 AntiInflammatory 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.

2) Before you take Nexium
Do not take Nexium if:
 You are allergic (hypersensitive) to esomeprazole or any of the other
ingredients of this medicine (listed in Section 6: Further information).
 You are allergic to other proton pump inhibitor medicines (e.g.
pantoprazole, lanzoprazole, rabeprazole, omeprazole).
 You are taking a medicine containing nelfinavir (used to treat HIV).
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.
Take special care with Nexium
Check with your doctor or pharmacist before taking Nexium if:
 You have severe liver problems.
 You have severe kidney problems.
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
 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).
Using other medicines
Please tell your doctor or pharmacist if you are taking, or have recently
taken, 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.
Do not take Nexium Tablets if you are taking a medicine containing
nelfinavir (used to treat HIV).
Tell your doctor or pharmacist if you are taking any of the following
 Atazanavir (used to treat HIV).
 Clopidogrel (used to prevent blood clots).
 Ketoconazole, itraconazole or voriconazole (used to treat infections
caused by a fungus).
 Erlotinib (used to treat cancer).
 Citalopram, imipramine or clomipramine (used to treat depression).
 Diazepam (used to treat anxiety, relax muscles or in epilepsy).

 Phenytoin (used in epilepsy). If you are taking phenytoin, your doctor will
need to monitor you when you start or stop taking Nexium.
 Medicines that are used to thin your blood, such as warfarin. Your doctor
may need to monitor you when you start or stop taking Nexium.
 Cilostazol (used to treat intermittent claudication – a pain in your legs
when you walk which is caused by an insufficient blood supply).
 Cisapride (used for indigestion and heartburn).
 Digoxin (used for heart problems).
 Methotrexate (a chemotherapy medicine used in high doses to treat
cancer) – if you are taking a high dose of methotrexate, your doctor may
temporarily stop your Nexium treatment.
 Tacrolimus (organ transplantation).
 Rifampicin (used for treatment of tuberculosis).
 St. John’s wort (Hypericum perforatum) (used to treat depression).
If your doctor has prescribed the antibiotics amoxicillin and clarithromycin
as well as Nexium to treat ulcers caused by Helicobacter pylori infection, it
is very important that you tell your doctor about any other medicines you
are taking.
Pregnancy and breast-feeding
Before taking Nexium, tell your doctor if you are pregnant or trying to get
pregnant. Ask your doctor or pharmacist for advice before taking any
medicine. Your doctor will decide whether you can take Nexium during this
It is not known if Nexium passes into breast milk. Therefore, you should
not take Nexium if you are breastfeeding.
Driving and using machines
Nexium is not likely to affect you being able to drive or use any tools or
Important information about some of the ingredients of Nexium
Nexium gastro-resistant tablets contain sucrose, which is a type of sugar. If
you have been told by your doctor that you have an intolerance to some
sugars, talk to your doctor before taking this medicine.

3) How to take Nexium
Always take Nexium exactly as your doctor has told you.
You should check with your doctor or pharmacist if you are not sure.
 Nexium gastro-resistant tablets are not recommended for children less
than 12 years old.
 If you are taking this medicine for a long time, your doctor will want to
monitor you (particularly if you are taking it for more than a year).
 If your doctor has told you to take this medicine as and when you need it,
tell your doctor if your symptoms change.
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
 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’).
How much to take
 Your doctor will tell you how many tablets to take and how long to take
them for. This will depend on your condition, how old you are and how
well your liver works.

4) Possible side effects

Nexium and contact a doctor immediately:
 Sudden wheezing, swelling of your lips, tongue and throat or body, rash,
fainting or difficulties in swallowing (severe allergic reaction).

(vomiting) and cramps.

 Taste changes.
 Eyesight problems such as blurred vision.

 Aggression.

Stevens-Johnson syndrome, toxic epidermal necrolysis).

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).
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.
