Sennoside B: Patient Guide for Constipation Relief
Sennoside B is a stimulant laxative used for short-term relief of occasional constipation. It works by stimulating bowel movements, usually within 6 to 12 hours, so it is commonly taken at bedtime.
Sennoside B can relieve occasional constipation, but abdominal cramps and diarrhea can occur. Use it only for short periods and follow the directions on your specific product label.
