Zoton (Prevacid) is used to treat or prevent indigestion - A feeling of discomfort or pain within the lower chest or abdomen caused by gastric acid irritation within the upper part of the gut namely the oesophagus, stomach or duodenum.

Heart burn is a burning feeling in the center of the chest, sometimes combined with an acid taste in the back of the mouth. Usually made worse by eating a large meal, straining or leaning forward. This is caused by acid from the stomach refluxing back into the gullet. Self help practical manoeuvres include; eating small meals often, putting two bricks under the head of the bed and avoiding tight clothing around the abdomen.

Classic indigestion comes on shortly after food and is a described as an intermittent burning discomfort in the top of the abdomen. Often helped temporarily by antacid medication (white medicine). Caused by irritation of the stomach wall (gastritis or an ulcer). If discomfort starts on an empty stomach it is more likely because of an ulcer or irritation of the section of gut which immediately follows the stomach called the duodenum. As well as medication, diet may help.

Zoton (Prevacid) (Lansoprazole) is very successful in treating the symptoms caused by acid irritation in all these areas. Even if you don't already have indigestion it is useful to give Zoton (Prevacid) to prevent these symptoms developing when steroids are given with chemotherapy.

How does Zoton (Prevacid) work?

It decreases the production of acid from the lining of the stomach. This protects the stomach, oesophagus and duodenum from irritation and ulceration. It works by blocking an enzyme (hydrogen-potassium adenosine tri-phosphatase) of the gastric parietal cell - so called proton pump inhibitor.

How is Zoton (Prevacid) taken?

A capsule containing 30mg of lansoprazole once a day. Sometimes other doses are recommended.

Swallow the capsule whole or if this is difficult you can open the capsule and mix the contents with fruit juice or yoghurt. It doesn't matter what time of day you take it but many people try to take it at the same time each day so its easier to remember.

If you forget to take your tablet don’t panic but try not to miss more than one or two tablets in a row.

Are there any side effects?

Zoton (Prevacid) is generally very well tolerated. Side effects are rare but include headache, diarrhoea and skin rashes.

Your doctor should be aware if you have problems with your liver and the dose should not be exceed 30mg per day as this may aggravate the liver.
