Oxyphenisatine (or oxyphenisatin) is a laxative.^[2] It is closely related to bisacodyl, sodium picosulfate, and phenolphthalein. Long term use is associated with liver damage,^[3] and as a result, it was withdrawn in most countries in the early 1970s. The acetate derivative oxyphenisatine acetate was also once used as a laxative.

Natural chemical compounds similar to oxyphenisatine may be present in prunes,^[4] but a recent review of the relevant scientific literature suggests that the laxative effect of prunes is due to other constituents including phenolic compounds (mainly neochlorogenic acids and chlorogenic acids) and sorbitol.^[5]
