Omeprazole contains the active substance omeprazole. It belongs to a
group of medicines called “proton pump inhibitors”. They work by reducing
the amount of acid that your stomach produces.
Omeprazole can be used as an alternative to oral therapy.
Do not use Omeprazole:
- if you are allergic (hypersensitive) to omeprazole 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, esomeprazole).
- if you are taking a medicine containing nelfinavir (used for HIV infection).
Do not use Omeprazole if any of the above applies to you. If you are not
sure, talk to your doctor, nurse or pharmacist before you are given this
Warnings and precautions
Omeprazole may hide the symptoms of other diseases. Therefore, if any of
the following happen to you before you are given Omeprazole or after you
are given 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).
- You experience severe or persistent diarrhoea, as omeprazole has been
associated with a small increase in infectious diarrhoea.
- You have severe liver problems.
- If you have ever had a skin reaction after treatment with a medicine similar to
Omeprazole Azevedos that reduces stomach acid.
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
Omeprazole Azevedos. Remember to also mention any other ill-effects like pain in
your joints.
Taking a proton pump inhibitor like omeprazole, 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).
Tell your doctor before taking this medicine, if:
- You are due to have a specific blood test (Chromogranin A).
Other medicines and Omeprazole

Omeprazole 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,

effects not listed in this leaflet, please tell your doctor or pharmacist.
