Fleet is the number 1 doctor-recommended brand for enemas(1). With Fleet Liquid Glycerin Suppositories, you get gentle constipation relief in minutes. They are easy-to-use, have a mess-free applicator with a lubricated gentle glide tip and are a comfortable, gentle alternative for those who prefer not to use an enema and also want stimulant-free relief. The liquid glycerin suppository is inserted rectally, allowing it to act locally in the colon without having to go through the entire digestive system. 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 Liquid Glycerin Suppositories. (1)IRI data, 52 weeks ending 1.29.23.
