Patient leaflet - PARIET 20 MG GASTRO-RESISTANT TABLETS
1. what pariet is and what it is used for
Pariet tablets contain the active ingredient rabeprazole sodium. This belongs to a group of medicines called ‘Proton Pump Inhibitors’ (PPIs). They work by lowering the amount of acid that your stomach produces.
Pariet tablets are used to treat the following conditions:
- ‘Gastro-oesophageal reflux disease’ (GORD), which can include heartburn. GORD is caused when acid and food from your stomach escapes into your food pipe (oesophagus)
- Ulcers in your stomach or the upper part of your gut (intestine). If these ulcers are infected with bacteria called ‘Helicobacter pylori’ (H. Pylori), you will also be given antibiotics. Using Pariet tablets and antibiotics together gets rid of the infection and makes the ulcer heal. It also stops the infection and ulcer from coming back
- Zollinger-Ellison Syndrome where your stomach produces too much acid
2. what you need to know before you take pariet

- You are allergic (hypersensitive) to rabeprazole sodium, or any of the other ingredients of this medicine (listed in Section 6).
