1. WHAT PARIET IS AND WHAT IT IS USED FOR
Pariet 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 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 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
Do not take Pariet if:
• You are allergic (hypersensitive) to rabeprazole sodium, or any of the other ingredients of Pariet (listed in
Section 6 below)
• You are pregnant or think that you are pregnant
• You are breast-feeding
Do not use Pariet if any of the above applies to you. If you are not sure, talk to your doctor or pharmacist
before using Pariet.
Also see Pregnancy, breast-feeding and fertility section.
Warnings and precautions
Check with your doctor or pharmacist before taking Pariet if:
• You are allergic to other proton pump inhibitor medicines or 'substituted benzimidazoles'
• Blood and liver problems have been seen in some patients but often get better when Pariet is stopped
• You have a stomach tumour
• You have ever had liver problems
• If you are taking atazanavir - for HIV infection
• If you have reduced body stores or risk factors for reduced vitamin B12 and receive long term treatment
with rabeprazole sodium. As with all acid reducing agents, rabeprazole sodium may lead to a reduced
absorption of vitamin B12
• If you have ever had a skin reaction after treatment with a medicine similar to Pariet that reduces
stomach acid.
• If you get a rash on your skin, especially in areas exposed to the sun tell your doctor as soon as you
can, as you may need to stop your treatment with Pariet. Remember to also mention any other illeffects like pain in your joints.
• You are due to have a specific blood test (Chromogranin A)
If you are not sure if any of the above applies to you, talk to your doctor or pharmacist before using Pariet.
Children
Pariet should not be used in children.
If you experience severe (watery or bloody) diarrhoea with symptoms such as fever, abdominal pain or
tenderness, stop taking Pariet and see a doctor straight away.
Taking a proton pump inhibitor like Pariet, especially over a period of more than one year, may slightly
increase your risk of fracture in the hip, wrist or spine. Tell your doctor if you have osteoporosis or if you are
taking corticosteroids (which can increase the risk of osteoporosis).
Other medicines and Pariet
Please tell your doctor or pharmacist if you are taking or have recently taken any other medicines. This
includes medicines obtained without a prescription, including herbal medicines.

blood and they should not be used together.
• Methotrexate (a chemotherapy medicine used in high doses to treat cancer) – if you are taking a high
