1. What Omeprazole Oral Suspension is and what it is used for

The name of your medicine is Omeprazole 4mg/ml, Powder for Oral Suspension (called Omeprazole Oral Suspension in this leaflet).

Omeprazole Oral Suspension 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 is commonly used to treat the following conditions:

In adults:

  • ‘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 upper part of the intestine (duodenal ulcer) or stomach (gastric ulcer).
  • Ulcers which 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.
  • 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.

In children:

Children over 1 month of age:

  • ‘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 over 4 years of age and adolescents:

  • Ulcers which are infected with bacteria called ‘Helicobacter pylori’. If your child has this condition, your doctor may also prescribe antibiotics to treat the infection and allow the ulcer to heal.

Your doctor will tell you why you have been given this medicine.

2. What you need to know before you take Omeprazole Oral Suspension

Do not take Omeprazole Oral Suspension

  • If you are allergic 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 (eg pantoprazole, lansoprazole, rabeprazole, esomeprazole).
  • If you are taking a medicine containing nelfinavir (used for HIV infection)

Do not take this medicine if any of the above apply to you. If you are not sure, talk to your doctor or pharmacist before taking Omeprazole Oral Suspension.

Warnings and precautions

Talk to your doctor or pharmacist before taking Omeprazole.

Omeprazole may hide the symptoms of other diseases. Therefore, if any of the following happen to you before you start taking Omeprazole Oral Suspension 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).
  • You experience severe or persistent diarrhoea, as omeprazole has been associated with a small increase in infectious diarrhoea.
  • You have severe liver problems.
  • You have ever had a skin reaction after treatment with a medicine similar to Omeprazole that reduces stomach acid
  • You are due to have a specific blood test (Chromogranin A)

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.

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).

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. Remember to also mention any other ill-effects like pain in your joints.

Children

Some children with chronic illnesses may require long-term treatment although it is not recommended. Do not give this medicine to children under 1 month of age.

Other medicines and Omeprazole Oral Suspension

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 Omeprazole can affect the way some medicines work and some medicines can have an effect on Omeprazole.

Do not take Omeprazole if you are taking a medicine containing nelfinavir (used to treat HIV infection).

Tell your doctor or pharmacist if you are taking any of the following medicines:

  • Ketoconazole, itraconazole, posaconazole or voriconazole (used to treat infections caused by a fungus)
  • Digoxin (used to treat heart problems)
  • 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 (used to treat HIV infection)
  • Tacrolimus (in cases of organ transplantation)
  • St John’s wort (Hypericum perforatum) (used to treat mild depression)
  • Cilostazol (used to treat intermittent claudication)
  • Saquinavir (used to treat HIV infection)
  • Clopidogrel (used to prevent blood clots (thrombi))
  • Erlotinib (used to treat cancer)
  • 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 Omeprazole treatment.

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.

Preparing and taking the suspension

The container is a two compartment system containing powder both in the cap and in the bottle. The two powders first need to be combined and are then to be constituted in water. A red mixing disk will drop into the medicine to help mix the powders and also mix the constituted suspension after addition of the water. It should remain in the bottle. The red cap is replaced by a grey cap after constitution. It is recommended that a pharmacist constitutes Omeprazole Oral Suspension prior to its dispensing to the patient.

Instructions for initial constitution.

Combination of powder in cap and bottle

  • Shake the bottle for 10 seconds to loosen the powder.
  • Twist the red cap anti-clockwise (see arrow on cap) until the seal is broken to release the powder in the red cap into the bottle.
  • Twist the red cap back to the original position, securely fastening the red cap onto the bottle.

Constitution of the powder

  • Shake the bottle vigorously for ten seconds to mix the powders.
  • Tap the base of the bottle three times on a hard horizontal surface to make sure all powder is in the bottle and not in the cap.
  • Remove the red cap from the bottle.
  • Add 64ml of water by using a suitable measuring device up to the line on the label.
  • Securely fasten the red cap onto the bottle and shake vigorously for 30 seconds.

Placement of syringe adaptor

  • Remove the red cap and red ring and throw away.
  • Insert the colourless, transparent Bottle Adaptor and replace the red cap with the grey plastic screw-cap.
  • Leave for fifteen minutes for product to reach final consistency.

Measuring your dose

Instructions for use of the syringe

1. Shake for 20 seconds immediately prior to each use.
2. To open the bottle, press the grey cap down and turn it anti-clockwise. Do not remove the white cap portion.
3. Take the syringe and put it into the adaptor opening.
4. Turn the bottle upside down.
5. Fill the syringe with a small amount of suspension by pulling the plunger down. Then push the plunger upward in order to remove any possible bubbles. Finally, pull the plunger down to the graduation mark corresponding to the quantity in millilitres (ml) prescribed by your doctor. The top flat edge of the piston should be in line with the graduation mark you are measuring to.
6. Turn the bottle the right way up.
7. Remove the syringe from the adaptor.
8. Put the end of the syringe into the mouth of the patient and push the plunger slowly back in to take the medicine. The suspension will be released slowly while the last portion will be released faster due to reduced resistance in the tip of the syringe.
9. Wash the syringe with water and let it dry before you use it again.
10. Close the bottle with the grey plastic screw cap - leave the bottle adaptor in the bottle.

Note: It is normal to have the red plastic disc in the suspension during use; do not attempt to remove it.

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.
  • Rash, possibly with pain in the joints.

Omeprazole Oral Suspension 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 medicine at this time.
