Kaiberu C

For these people and situations
Product Overview

Kaiberu C is an OTC laxative containing the maximum approved amounts of bisacodyl and sennoside, known as active ingredients in stimulant laxatives, within the OTC laxative standards (3 Tablets per day). These two active ingredients work by different mechanisms on the colon to effectively treat stubborn constipation caused by sluggish bowel movement.
The small, easy-to-swallow pink Tablets are enteric-coated, so they do not dissolve in the stomach but reach the colon to act directly. Taking before bedtime works on the colon during sleep and promotes bowel movement the next morning. The dose can be adjusted between 1 to 3 Tablets according to bowel condition, so first-time users can start with 1 Tablet.
