Consumer Medicine Information

What is in this leaflet

This leaflet answers some of the common questions people ask about MEPREZE.

It does not contain all the information that is known about MEPREZE.

It does not take the place of talking to your pharmacist or doctor.

All medicines have risks and benefits. Your pharmacist will have weighed the risks of you taking MEPREZE against the benefits they expect it will have for you.

If you have any concerns about taking this medicine, ask your pharmacist or doctor.

Keep this leaflet with the medicine.

You may need to read it again.

What MEPREZE is used for

MEPREZE is used for the relief of frequent heartburn and stomach acid complaints due to gastro-oesophageal reflux disease (GORD). This can be caused by "washing back" (reflux) of food and acid from the stomach into the food pipe (oesophagus).

Reflux can cause a burning sensation in the chest rising up to the throat, also known as heartburn.

Frequent heartburn is when you have heartburn for two or more times a week. Heartburn that occurs frequently is a typical symptom of GORD.

Who should use MEPREZE

MEPREZE is recommended for adults 18 years of age and over, who suffer from frequent heartburn at least 2 times a week.

MEPREZE is not the right medicine for you if you suffer heartburn only occasionally (one episode of heartburn a week or less), or if you want immediate relief of heartburn.

How MEPREZE works

MEPREZE is a type of medicine called a proton-pump inhibitor. It works by decreasing the amount of acid made by the stomach. This gives relief of symptoms and also allows healing to take place. This does not stop food being digested in the normal way.

MEPREZE is available only from your pharmacist. It can be purchased directly from your local pharmacy without a doctor's prescription.

There is no evidence that this medicine is addictive.
