Omeprazole enteric-coated tablets
Consumer Medicine Information
This leaflet answers some common questions about Meprazol. It does not contain all the available information. It does not take the place of talking to your doctor or pharmacist.
All medicines have risks and benefits. Your doctor has weighed the risk of you taking this medicine against the benefits it is expected to have for you.
If you have any concerns about taking this medicine, ask your doctor or pharmacist.
Keep this leaflet with the medicine. You may need to read it again.
The name of your medicine is Meprazol. It contains the active ingredient omeprazole.
Meprazol is used to treat the following conditions:
This medicine is used to treat reflux oesophagitis (reflux disease) and to help stop it coming back or relapsing. Reflux can be caused by “washing back” (reflux) of food and acid from the stomach into the food pipe (oesophagus). Reflux can cause heartburn, a burning sensation in the chest rising up to the throat.
Treatment and prevention of peptic ulcers
Meprazol is used to help heal peptic ulcers.
Depending on the position of the ulcer it is called a gastric or duodenal ulcer. A gastric ulcer occurs in the stomach. A duodenal ulcer occurs in the duodenum which is the tube leading out of the stomach. This can be caused in part by too much acid being made in the stomach.
This medicine is also used to help stop gastric and duodenal ulcers from coming back.
Combination therapy for the treatment of peptic ulcers associated with Helicobacter pylori infection
Helicobacter pylori is a bacteria that often occurs in the stomach together with peptic ulcers. It is important to kill Helicobacter pylori to let your peptic ulcer heal. Meprazol is usually combined with two antibiotics to help kill this bacteria. However, it is possible that the antibiotics might not always be able to kill Helicobacter pylori.
Treatment and prevention of peptic ulcers associated with non-steroidal anti-inflammatory drugs (NSAIDs)
Non-steroidal anti-inflammatory drugs are used to relieve pain, swelling and other symptoms of inflammation, including arthritis and joint pain. Some peptic ulcers are caused by taking these NSAIDs. Meprazol is used to treat and help prevent ulcers developing which are associated with long term NSAID use.
Meprazol is also used to treat a rare condition called Zollinger-Ellison syndrome, where the stomach produces very large amounts of acid, much more than in ulcers and reflux disease.
Ask your doctor if you have any questions about why this medicine was prescribed for you. Your doctor may have prescribed it for another reason.
Meprazol belongs to a group of medicines called proton pump inhibitors (PPIs).
It works by decreasing the amount of acid made by the stomach, to give relief from the symptoms and allow healing to take place. This does not stop food being digested in the normal way.
There is no evidence that this medicine is addictive.
Do not take this medicine if:
Tell your doctor if you have allergies to:
Also tell your doctor if you have or have had any problems with your liver or any other medical conditions.

These medicines may be affected by Meprazol, or may affect how well it works. You may need to use different amounts of your medicine, or you may need to take different medicines.
Your doctor and pharmacist have more information on medicines to be careful with or avoid while taking this medicine.
The dosage recommendation and duration of treatment will be determined for your specific condition by your doctor. Follow your doctor’s instructions about how and when to take Meprazol carefully. They may differ from the information contained in this leaflet.
For adults, the usual dose is one tablet (20mg omeprazole) per day. The dose may vary from 10mg to 40mg a day depending on the condition you are being treated for and how severe it is.
For children (one year or older), the dose depends on the body weight. For children 10kg to 20kg, the dose is 10mg omeprazole per day. This dose may be increased to 20mg if required. For children more than 20kg the dose is 20mg per day. This dose may be increased to 40mg if required.
Meprazol enteric-coated tablets must be SWALLOWED WHOLE with a glass of water. IF THE TABLETS ARE BROKEN, CRUSHED OR CHEWED, THEY WILL NOT WORK PROPERLY.
Take your medicine at the same time each day. It can be taken with or without food.
A 10mg dose is not available from this brand. For any 10mg doses that may be required, alternative brands are available.
Symptoms will be relieved rapidly in most patients, and healing usually takes place within four weeks.
If your symptoms return, tell your doctor. If you have been treated for Helicobacter pylori, the antibiotics might not have killed the bacteria, and you will have to be treated again.
Take your dose as soon as you remember, and continue to take it as you would normally.
If it is almost time for your next dose, skip the dose you missed and take your next dose when you are meant to.
Do not take a double dose to make up for the dose you missed. This may increase the chance of you getting an unwanted side effect.

If you have trouble remembering when to take your medicine, ask your pharmacist for some hints.
