What Maxor is used for
Gastro-oesophageal reflux disease (GORD)
Maxor is used to treat and prevent gastro-oesophageal reflux disease (GORD) from returning. This can be caused by “washing back” (reflux) of food and acid from the stomach into the oesophagus (food pipe).
Reflux can cause a burning feeling in the chest rising up to the throat, also known as heartburn.
Maxor is also taken to help stop reflux oesophagitis coming back or relapsing.
Maxor is used to treat peptic ulcers. Depending on the position of the peptic 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.
Ulcers can be caused in part by too much acid being made in the stomach.
Maxor is also used to help stop gastric or duodenal ulcers coming back.
Peptic Ulcers Associated with Helicobacter pylori Infection
Most people who have a peptic ulcer also have a bacterium called Helicobacter pylori in their stomach. Maxor can be taken with antibiotics to treat this infection. The antibiotics are used to kill the bacteria while Maxor allows the ulcers to heal.
You may need further treatment with antibiotics.
Peptic Ulcers Associated with Non-steroidal Anti-inflammatory Drugs (NSAIDs)
Some peptic ulcers are caused by taking medicines called non-steroidal anti-inflammatory drugs (NSAIDs), a type of medicine used to treat pain or inflammation.
Maxor is also used to heal and prevent ulcers associated with NSAIDs.
Maxor is used to treat a rare condition called Zollinger-Ellison syndrome. In this condition, the stomach produces very large amounts of acid, much more than in ulcers and reflux disease.
Your doctor may have prescribed Maxor for another reason. Ask your doctor if you have any questions about why Maxor has been prescribed for you.
How Maxor works
Maxor belongs to a group of medicines called proton pump inhibitors. It works by reducing the amount of acid made by the stomach, to give relief of symptoms and allow healing to take place. This does not stop food being digested in the normal way.
Follow all directions given to you by your doctor carefully. They may differ from the information contained in this leaflet.
Ask your doctor if you have any questions about why this medicine has been prescribed for you. Your doctor may prescribe this medicine for another reason.
Maxor is not recommended for use in children, as there is no experience with Maxor capsules in children.
Maxor is available only with a doctor’s prescription.
There is no evidence that Maxor is addictive.

How to take Maxor
Follow all directions given to you by your doctor and pharmacist carefully. They may differ from the information contained in this leaflet.
If you do not understand the instructions on the carton, ask your doctor or pharmacist for help.
How much to take
The dose varies from patient to patient. Your doctor will decide the right dose for you.
The usual dose is 20 mg a day. Your doctor may vary this dose depending on your condition.
How to take it
Swallow the capsules whole with a glass of water.
Do not crush or chew the capsules. If the granules in the capsules are crushed or chewed they will not work properly.

Take Maxor at the same time each day. Keeping a regular time for taking Maxor will help to remind you to take it.
Maxor can be taken with or without food.
How long to take it for
Continue taking your medicine for as long as your doctor tell you to.
To properly heal an ulcer or to treat reflux disease, you will need to take Maxor for 4 to 8 weeks.
If you are taking Maxor to stop an ulcer from coming back or to treat other conditions, your doctor will tell you for how long you need to take the tablets.
Tell your doctor if your symptoms return. You may need further treatment with omeprazole.
If your condition is associated with Helicobactor pylori, you may need a repeat course of antibiotics plus omeprazole.
If you forget to take it
If it is almost time for your next dose, skip the dose you missed and take your next dose when you are meant to.
Otherwise, take the missed dose as soon as you remember, and then go back to taking your capsules as you would normally.
Do not take a double dose to make up for the dose you missed.
If you are not sure what to do, ask your doctor or pharmacist.
If you have trouble remembering when to take your medicine, ask your pharmacist for some hints.

Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.
Symptoms of an overdose may include nausea, vomiting, dizziness, stomach pain, diarrhoea, headache and confusion.

Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking Maxor.

After taking Maxor
Keep your capsules in the original container, until it is time to take them. If you take the capsules out of the blister, they may not keep well.
