(2) Although this drug disintegrates easily in the oral cavity, it is not absorbed through the mucous membranes of the oral cavity, so after dissolving it in the mouth, swallow it with saliva or with water or hot water. Just like regular tablets, the effect remains the same even if you take it as is with water or hot water.

(Medications are generally not taken together with alcoholic beverages.)

This medicine is not a medicine to be taken at set times, but rather a medicine to be taken when symptoms appear. It is not affected by meals, so you can take it before, after, or between meals.
One tablet at a time will control excess stomach acid for about 8 hours, so if you take it twice a day, please wait at least 8 hours apart.
