Possibility of malignancy in the stomach must be removed before treatment is given, because treatment with Lansoprazole may cover the symptoms of malignancy so that the diagnosis is delayed. Should be taken in the morning before meals. Capsules should not be opened, chewed or destroyed and must be completely swallowed. Caution in use for pregnant women, breastfeeding women or children. Breastfeeding must be stopped if it is really deemed necessary to get Lansoprazole treatment.
