• 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 Omeprazole
• Medicines that are used to thin your blood, such as warfarin or other vitamin K blockers. Your doctor ^ may need to monitor you when you start or stop taking Omeprazole.
• Rifampicin (used to treat tuberculosis)
• Atazanavir and saquinavir (used to treat HIV infections)
• Tacrolimus (in cases of organ transplantation)

If your doctor has prescribed the antibiotics amoxicillin and clarithromycin as well as omeprazole to treat ulcers caused by Helicobacter pylori infection, it is very important that you tell your doctor about any other medicines you are taking.
If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.
Omeprazole is used to treat the following conditions:
• '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. Omeprazole is also used in the long term management of this condition.
• Ulcers in the upper part of the intestine (duodenal ulcer) or stomach (gastric ulcer). Omeprazole can be used to treat this condition or prevent its reoccurrence.
• Ulcers which are infected with bacteria called 'Helicobacterpylori'. If you have this condition, your doctor may also prescribe antibiotics to treat the infection and allow the ulcer to heal.
• Ulcers caused by medicines called NSAIDs (Non-Steroidal Anti-Inflammatory Drugs). Omeprazole can also be used to stop ulcers from forming if you are taking NSAIDs.
• Too much acid in the stomach caused by a growth in the pancreas (Zollinger-Ellison syndrome).
Children over 1 year of age and weighing 10 kg or more
• '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.
In children, the symptoms of the condition can include the return of stomach contents into the mouth (regurgitation), being sick (vomiting) and poor weight gain.
Children and adolescents over 4 years of age
• Ulcers which are infected with bacteria called 'Helicobacterpylori'. If your child has this condition, your doctor may also prescribe antibiotics to treat the infection and allow the ulcer to heal.
• 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 medicines containing other proton pump inhibitors (e.g. pantoprazole, lansoprazole, rabeprazole, esomeprazole).
• if you are taking any medicine containing nelfinavir (for HIV infection).
Talk to your doctor or pharmacist before taking Omeprazole if:
• You have reduced body stores or risk factors for reduced vitamin B and are to receive omeprazole long term. Omeprazole may reduce the absorption of vitamin B.
Omeprazole may hide the symptoms of other diseases. Therefore, if any of the following happen to you before you start taking Omeprazole 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 (be sick) food regularly or if you notice your vomit contains blood (this may look like coffee granules).
• You pass black stools (blood-stained faeces).
• You have severe liver problems.
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).
Talk to your doctor or pharmacist if you experience severe or persistent diarrhoea, as omeprazole has been associated with a small increase in infectious diarrhoea.
If you take omeprazole on a long-term basis (longer than 1 year) your doctor will probably keep you under regular surveillance. You should report any new and exceptional symptoms and circumstances whenever you see your doctor.
Omeprazole may alter the results of some tests related to cancer. Tell your doctor, nurse or hospital staff that you are taking this medicine. Your doctor may advice you to stop taking this medicine for at least five days if you are undergoing certain tests.
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines, including medicines obtained without a prescription. This is because omeprazole can affect the way some medicines work and some medicines can have an effect on omeprazole.
