The medication is taken by mouth or via the rectum. It typically begins working in minutes when given by rectum and within twelve hours when given by mouth. It is a weaker laxative than bisacodyl or castor oil. Sennoside A, one of the sennosides present in the laxative medication, has recently proven effective in inhibiting the ribonuclease H (RNase H) activity of human immunodeficiency virus (HIV) reverse transcriptase."}]
