WHAT ZOTON FASTABS
IS USED FOR
PEPTIC ULCERS
Zoton FasTabs is used to treat peptic
ulcers in adults. Depending on the
position of the ulcer it is either a
gastric or duodenal ulcer. A gastric
ulcer occurs in the stomach. A
duodenal ulcer occurs in the
duodenum, which is the tube leading
out of the stomach.
Too much acid being made in the
stomach can cause these ulcers.
Zoton FasTabs is also used to help
stop duodenal ulcers from coming
back.
REFLUX OESOPHAGITIS
Zoton FasTabs is used to treat the
symptoms of reflux oesophagitis or
reflux disease in adults and in
children from 6 to 17 years of age.
This can be caused by backflow
(reflux) of food and acid from the
stomach into the food pipe or gullet,
also known as the oesophagus.
Reflux can cause a burning sensation
in the chest rising up to the throat,
also known as heartburn.
HEARTBURN AND STOMACH PAIN
ASSOCIATED WITH REFLUX OR PEPTIC
ULCER.
Zoton FasTabs is used for the short-
term treatment of heartburn and
peptic ulcer symptoms in adults.
PEPTIC ULCERS ASSOCIATED WITH
HELICOBACTER PYLORI INFECTION
Most people who have a peptic ulcer
also have bacteria called
Helicobacter pylori in their stomach.
Zoton FasTabs can be taken in
conjunction with certain antibiotics
to help eradicate Helicobacter pylori
and let your peptic ulcer heal.
However, it is possible that the
antibiotics may not always get rid of
Helicobacter pylori.
