What is in this leaflet

This leaflet answers some common questions about your medicine. 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 risks of you using this medicine against the benefits they expect it will have for you.

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

Keep this leaflet with your medicine. You may want to read it again.

What this medicine is used for

Pantoprazole is used for symptomatic relief of frequent heartburn and stomach acid complaints due to gastro-oesophageal reflux (GORD).

Reflux 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 GORD.

How it 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 of reflux and heartburn.

This medicine will start to suppress acid within a few hours, however, it will not give instant symptom relief. You may need to take it for a few days before experiencing the full effect.

This medicine is recommended for adults suffering from heartburn at least two times a week. It 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.

Ask your doctor or pharmacist if you have any questions about why this medicine has been recommended for you.

This medicine is a “Pharmacist Only Medicine”. It is available without a doctor’s prescription, but your pharmacist’s advice is required.

This medicine is not addictive.

Do not give this medicine to children or adolescents under 18 years of age. There is not enough information to recommend the use of this medicine in children under 18 years of age.

Your doctor and pharmacist have more information on medicines to be careful with or avoid while taking pantoprazole.

Other interactions not listed above may also occur.

How to take it

Swallow the tablet whole with a full glass of water, with or without food.

This medicine should be taken for at least seven days, and up to 14 days.

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 it as soon as you remember, and then go back to taking your medicine as you would normally.

Do not take a double dose to make up for the dose that you missed. This may increase the chance of you getting an unwanted side effect.

Immediately telephone your doctor or the Poisons Information Centre (telephone 13 11 26) for advice, or go to Accident and Emergency at the nearest hospital, if you think that you or anyone else may have taken too much pantoprazole.
