Consumer Medicine Information

NOTICE: This Consumer Medicine Information (CMI) is intended for persons living in Australia. This page contains answers to some common questions about Gastenz. It does not contain all the information that is known about Gastenz. 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 using this medicine against the benefits he/she expects it will have for you. If you have any concerns about using this medicine, ask your doctor or pharmacist. Bookmark or print this page, you may need to read it again.

What Gastenz is used for

Gastenz contains the active ingredient pantoprazole.
It is used for lasting symptomatic relief of frequent heartburn and stomach acid complaints due to gastro-oesophageal reflux.
This can be caused by washing back (reflux) of food and acid from the stomach into the food pipe, also known as the 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 days a week. Heartburn that occurs frequently is a typical symptom of gastro-oesophageal reflux disease (GORD).
Gastenz is recommended for adults 18 years of age and over, suffering from heartburn at least 2 times a week.
It is not the right medicine for you if you suffer from heartburn only occasionally (one episode of heartburn a week or less), or if you want immediate relief of heartburn.

How Gastenz works

Pantoprazole belongs to a group of medicines called proton pump inhibitors (PPIs). It works by decreasing the amount of acid the stomach makes, to give relief from the symptoms.
It will start to suppress acid within a few hours, however it will not give instant symptom relief. You may need to take this medicine for a few days before experiencing the full effect.
This medicine is not addictive.
