It does not contain all of the available information. It does not take the place of talking to your doctor or pharmacist.

All medicines have benefits and risks. Your doctor or pharmacist has weighed the risks of you taking Maxor Heartburn Relief against the benefits they expect it will have for you.

What Maxor Heartburn Relief is used for

Gastro-oesophageal reflux disease (GORD)

Maxor Heartburn Relief is used for the relief of 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 oesophagus (food pipe).

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

Who should use Maxor Heartburn Relief

Maxor Heartburn Relief is recommended for:

  • adults 18 years of age and over, and suffer from heartburn at least 2 times a week.

Maxor Heartburn Relief 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 Maxor Heartburn Relief works

Maxor Heartburn Relief belongs to a group of medicines called proton pump inhibitors. It works by reducing the amount of acid made by the stomach. This helps reduce pain and also allows any damage to heal.

Maxor Heartburn Relief is not recommended for use in children, as there is no experience with Maxor Heartburn Relief capsules in children.

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

There is no evidence that Maxor Heartburn Relief is addictive.
