Fleet is the number 1 doctor-recommended brand for enemas(1). With Fleet Glycerin Suppositories, you get gentle constipation relief in minutes. Glycerin Suppositories are formulated with aloe and are a convenient alternative for those who prefer not to use a liquid enema for adult constipation. The suppository is easily inserted rectally, allowing it to act locally in the colon without having to go through the entire digestive system and is a good option for stimulant-free relief. The suppository is designed to partially dissolve, which may or may not be noticeable. Fleet Glycerin Suppositories work by attracting water into the colon, making it easier to promote a bowel movement. Our glycerin suppositories are ideal for gentle relief for those who suffer from occasional constipation. Free yourself from discomfort caused by adult constipation within 15 minutes to 1 hour with Fleet Glycerin Suppositories. (1)IRI data, 52 wks ending 1.29.23.
