Additional Information
Kaibeel C contains bisacodyl and sennoside at the maximum approved amounts, making it effective for persistent, troublesome constipation and its associated discomfort.
Taking at bedtime allows the medication to work in the large intestine overnight, with results expected the following morning. Effect onset varies by individual and severity of constipation, generally within 6 to 12 hours.
Urine may become yellow-brown or reddish-brown after taking this medication. This is caused by the active ingredient, sennoside.
