1. Why am I taking ESOPREZE?

ESOPREZE contains the active ingredient esomeprazole magnesium trihydrate. ESOPREZE is a type of medicine called a proton-pump inhibitor. It works by decreasing the amount of acid made by the stomach, to give relief of symptoms and allow healing to take place.

ESOPREZE is used to treat reflux oesophagitis. This can be caused by “washing back” (reflux) of food and acid from the stomach into the food pipe (oesophagus). ESOPREZE is also taken to help stop reflux oesophagitis coming back or relapsing.

ESOPREZE is taken to treat the symptoms of pain or discomfort in the stomach caused by NSAIDs, a type of medicine for pain or inflammation. ESOPREZE is also taken to help heal and prevent ulcers caused by NSAIDs.

ESOPREZE together with antibiotics is taken to treat peptic ulcer. Most people who have a peptic (gastric and duodenal) ulcer also have a bacterium called Helicobacter pylori in their stomach.

When ESOPREZE and antibiotics are taken together, they work to kill the bacterium and let your ulcer heal. You may need further treatment with antibiotics.

ESOPREZE is also used to treat a rare condition called Zollinger-Ellison syndrome. This is a condition where the stomach produces large amounts of acid, much more than in ulcers or reflux disease.

ESOPREZE is taken as follow up treatment for bleeding peptic ulcers.

4. How do I take ESOPREZE

How much to take

  • Take one ESOPREZE tablet each day, unless your doctor has told you otherwise. The dose of ESOPREZE tablets is usually 20 mg or 40 mg a day depending on what condition you are being treated for and how severe it is.
  • Follow the instructions provided and use ESOPREZE until your doctor tells you to stop.

When to take ESOPREZE

  • Take ESOPREZE at about the same time each day.
  • Keeping a regular time for taking ESOPREZE will help to remind you to take it.

How to take ESOPREZE

Swallow ESOPREZE tablets whole with a glass of water. Do not crush or chew the tablets.

If the tablets are chewed or crushed they will not work properly.

If you have difficulty swallowing the tablets:

  1. Place the tablet in half a glass of non-carbonated water. Mineral water or other liquids are not suitable.
  2. Gently mix the tablet and water by stirring, taking care not to crush the tablet.
  3. Stir until the tablet dissolves into little pellets.
  4. Drink the liquid with the pellets immediately, or within 30 minutes. Do not chew the pellets.
  5. Rinse the glass with half a glass of water and drink.
  • If you cannot swallow at all, follow steps 1-3 above to disperse the tablets and administer the liquid and pellets through a gastric tube.

If you forget to take ESOPREZE

ESOPREZE should be taken regularly at the same time each day. If you miss your dose at the usual time, take it as soon as you remember, and then go back to taking 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.

If you take too much ESOPREZE

You should immediately:

  • phone the Poisons Information Centre
