Best Suppositories for Constipation (2026): Glycerin, Bisacodyl and Kids Picks

The plain adult glycerin suppository, from the brand that defines it. The Fleet Glycerin Suppositories, 50 count jar is what a pharmacist reaches for when an adult asks for something faster than a pill and gentler than a stimulant. The Drug Facts label states glycerin 2 g per suppository, lists the use as relief of occasional constipation, and says it generally produces a bowel movement in 15 minutes to 1 hour. Directions on the label: adults and children 6 years and over, 1 suppository once daily or as directed by a doctor; children under 6, ask a doctor.

What the label says to watch: ask a doctor before use if you have stomach pain, nausea or vomiting, or a sudden change in bowel habits that lasts over 2 weeks. Stop use and ask a doctor if you have rectal bleeding or fail to have a bowel movement after use, and do not use a laxative for more than 1 week unless directed by a doctor. Owners consistently report the jar suppositories can arrive soft in summer; the fix on the label is to chill them before unwrapping. Full write-up in our Fleet Glycerin Suppositories review; the wider field is in the best glycerin suppositories, and the timing question is answered in how long a glycerin suppository takes to work.

The wrapped alternative. The NeilMed Glycerin Laxative Suppositories put the same active as Fleet, glycerin, in individually wrapped units, 30 to the box per the listing title. The label use is relief of occasional constipation, and like every glycerin suppository it is hyperosmotic. NeilMed is best known for saline rinses, and its laxative line brings the same packaging discipline: a wrapper per unit, a sealed box, and a listing that states the count.

The listing title does not state the glycerin amount per suppository; the Drug Facts panel on the box does, so read it rather than assuming it matches Fleet's 2 g. The same label lines apply: stop and ask a doctor for rectal bleeding or no bowel movement after use, and no laxative beyond 1 week without a doctor. The full brand write-up is our NeilMed suppositories review.

Same strength, different house. The Rising Proctozone-GMax Adult Glycerin Suppositories state 2 g glycerin per suppository in the listing title, which is the adult strength the category runs on, and the title labels them a rectal laxative for fast relief of occasional constipation. Rising Health is a generic pharmaceutical brand rather than a consumer name, which is why you may not recognize it and why the price sits where it does.

The Drug Facts lines are the standard glycerin set: ask a doctor before use for stomach pain, nausea, vomiting or a sudden change in bowel habits over 2 weeks; stop and ask a doctor for rectal bleeding or no bowel movement after use; not more than 1 week without a doctor. For the adult-only field with every count and price side by side, see the best glycerin suppositories for adults.

The format for people who will not use a solid. Fleet Liquid Glycerin Suppositories are glycerin in a small pre-filled applicator with a tip that is inserted, squeezed and discarded. Nothing has to be unwrapped, warmed, or held. The Drug Facts label reads relief of occasional constipation and generally produces a bowel movement in 15 minutes to 1 hour, the same window as the solid suppository, and the directions are for adults and children 6 years and over, with under 6 sent to a doctor.

The listing title does not state the glycerin amount per applicator; the Drug Facts panel does. Same stop lines as every laxative here: rectal bleeding, no bowel movement after use, more than 1 week, all mean ask a doctor. The full format comparison is in the best liquid glycerin suppositories.

The stimulant, sized for occasional use. Dulcolax Stimulant Laxative Medicated Suppositories contain bisacodyl 10 mg per suppository. Where glycerin draws water in, bisacodyl acts on the bowel wall directly, which is why the label calls it a stimulant laxative and why we put it below glycerin rather than beside it. The Drug Facts label reads relief of occasional constipation and generally produces a bowel movement in 15 minutes to 1 hour. Directions: adults and children 12 years and over, 1 suppository in a single daily dose; children 6 to under 12 years have a separate reduced direction printed on the label; children under 6, ask a doctor.

The label's own caution list for bisacodyl includes the standard laxative lines, rectal bleeding, no bowel movement after use, and not more than 1 week without a doctor, plus abdominal discomfort, faintness and cramps as possible effects. Read the box you buy; the suppository label carries its own warnings. The head-to-head is in glycerin vs bisacodyl suppositories and the brand deep dive is the Dulcolax suppositories review.

Same active, generic label, lower price per dose. Major Bisacodyl 10 mg Suppositories come 12 to the box, comfort-shaped per the listing title, and the label describes them as a stimulant laxative for gentle, predictable, fast relief. The strength is the category standard 10 mg, the same as Dulcolax. At $9.99 (verified via the Amazon Creators API on September 5, 2026) that is about 83 cents a dose ($9.99 divided by 12).

Directions and warnings are the bisacodyl set: single daily dose, separate reduced direction for children 6 to under 12, ask a doctor under 6, stop and ask a doctor for rectal bleeding or no bowel movement after use, and not more than 1 week without a doctor. The full bisacodyl field, including Paddock and NeilMed, is ranked in the best bisacodyl suppositories.

The kids product with the clearest label. Pedia-Lax Liquid Glycerin Suppositories are Fleet's pediatric line: glycerin in a small pre-filled applicator sized for a child, 6 per box, labeled for relief of occasional constipation in children ages 2 to 5. The label's direction for under 2 years is ask a doctor. That single age line is the reason this product, and not a cut-down adult suppository, is the pick for a young child.

Owners consistently report the applicator is easier on a wriggling child than a solid suppository, which is the practical case for the liquid format at this age. The brand review is our Pedia-Lax review, the kids field is ranked in the best glycerin suppositories for kids, and the adult-versus-pediatric question is settled in Fleet vs Pedia-Lax.

A pediatric strength, not a cut-down adult. The Rising Health Children's Glycerin Suppositories state 1.2 g glycerin per suppository in the listing title, along with the age range, kids 2 to 5 years, and the use, a rectal laxative for fast relief of occasional constipation. That is a purpose-made pediatric size. The adult suppository is 2 g; the pediatric category runs roughly 1 to 1.2 g, and this one prints the number.

Directions and stop lines are the pediatric glycerin set: ages 2 to 5 on the title, ask a doctor under 2 on the label, stop and ask a doctor for rectal bleeding or no bowel movement after use. And the standing rule for every child: the pediatrician decides. If you are choosing for a baby rather than a toddler, the age lines are different and the products are different; read the best glycerin suppositories for infants and suppositories for babies and toddlers before buying anything.
