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

What PARZOL 20 is used for

PARZOL 20 is used to:

  • treat reflux oesophagitis or reflux disease. This can be caused by food and acid from the stomach flowing the wrong way (reflux) back up the food pipe, also known as the oesophagus.
    Reflux can cause a burning sensation in the chest rising up the throat, also known as heartburn.
  • help stop reflux oesophagitis from coming back or relapsing
  • treat peptic ulcers. Depending on the position of the ulcer it is called a gastric or duodenal ulcer occurs in the stomach. A duodenal ulcer occurs in the duodenum which is the tube leading out of the stomach.
    These ulcers can be caused by too much acid being made in the stomach.
    Most people who have a peptic ulcer also have a bacteria called Helicobacter pylori in their stomach. Your doctor may also prescribe a course of antibiotics (clarithromycin and amoxicillin) for you. When PARZOL 20 is taken with antibiotics, the combination therapy will kill the Helicobacter pylori and let your ulcer heal.
    The presence of the bacteria Helicobacter pylori may cause the stomach to become inflamed, resulting in pain, nausea and vomiting. When PARZOL 20 is taken with antibiotics, they will help kill Helicobacter pylori and allow the stomach to heal.

PARZOL 20 belongs to a group of medicines called proton pump inhibitors (PPIs). PARZOL 20 works by decreasing the amount of acid the stomach makes, to give relief from the symptoms and allow healing to take place. Your food will still be digested in the normal way.

Your doctor may have prescribed PARZOL 20 for another reason. Ask your doctor if you have any questions about why PARZOL 20 has been prescribed for you.

PARZOL 20 is available only with a doctor’s prescription.

How to take PARZOL 20

How much to take

The usual dose is one tablet at the same time each day. For treating Helicobacter pylori infections in combinations with antibiotics (clarithromycin and amoxicillin), the dose is one tablet twice each day, morning and evening.

Follow all directions given to you by your doctor and pharmacist carefully.

How to take PARZOL 20

Swallow the tablets with a glass of water.

Do not crush or chew the tablets. They have a special coating, which protects them from the acid in your stomach. If you crush or chew PARZOL 20 tablets, they will not work as well. It does not matter if you take PARZOL 20 with food or on an empty stomach.

If you forget to take PARZOL 20
