Check price on Amazon →Best Liquid Glycerin Suppositories (2026): Fleet and Pedia-Lax Applicators Compared
Fleet Liquid Glycerin Suppositories, 4 applicators for $5.58, is the liquid pick: glycerin in a single-use pre-filled applicator, a Drug Facts label that reads 15 minutes to 1 hour, and no solid to handle. This page covers every liquid glycerin listing on Amazon, adult and pediatric, and puts the solid jar beside them so the price of the format is honest. Prices verified via the Amazon Creators API on September 5, 2026.
By The Pharmacy Desk2026-09-05~10 min read Ranked on verified label facts, never box claimsHow we research
Buy Fleet Liquid Glycerin Suppositories, 4 applicators, at $5.58 (verified via the Amazon Creators API on September 5, 2026). It is glycerin in a small pre-filled applicator, labeled for relief of occasional constipation with a bowel movement generally in 15 minutes to 1 hour, adults and children 6 years and over, and it costs about $1.40 per use. For a child aged 2 to 5, the pediatric version is Pedia-Lax Liquid Glycerin Suppositories, 6 for $12.81. Both are Fleet products, and between them they are the entire liquid glycerin shelf on Amazon.
A liquid glycerin suppository is not a different medicine from a solid one. It is glycerin delivered from a pre-filled applicator: insert the tip, squeeze, discard. The Drug Facts label is the same as the solid's in every line that matters, occasional constipation, 15 minutes to 1 hour, stimulant-free, the same age cut-offs and the same stop lines. What changes is handling. There is nothing to unwrap, nothing to keep firm, nothing to hold in place, which is why the liquid is the format for people with limited dexterity, for caregivers helping someone else, and for young children, whose pediatric line is liquid first. The cost of that convenience is real, roughly fifteen times the solid jar per use, and this page shows the arithmetic rather than hiding it.
Label lines for the shelf. Adult liquid glycerin: adults and children 6 years and over, 1 applicator; under 6, ask a doctor. Pediatric liquid glycerin: children ages 2 to 5; under 2, ask a doctor. All: 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; no laxative beyond 1 week without a doctor. For any child, the pediatrician decides. We read labels and verify listings; we are not clinicians, nothing here is medical advice, and no brand paid for a placement.
The short version
- Our Pick: Fleet Liquid Glycerin Suppositories, 4 for $5.58 at our September 5, 2026 check, about $1.40 per use. Same label window as the solid, no solid to handle.
- Buying more: the Fleet 3 pack is 12 for $17.37, about $1.45 per use, so no saving; the larger pack at $22.32 does not state its count on the listing.
- Kids 2 to 5: Pedia-Lax Liquid Glycerin, 6 for $12.81 (about $2.14 each) or 18 for $21.11 (about $1.17 each); ask a doctor under 2.
- The price of the format: the Fleet solid 50 count jar is $4.29, about 9 cents a dose. Liquid costs fifteen times that; buy it because the solid is the barrier, not because it works differently.
- Every liquid glycerin label carries the same stop lines as the solid: rectal bleeding, no bowel movement after use, or use beyond 1 week means ask a doctor.

Fleet Liquid Glycerin Suppositories, 4 applicators
Fleet
The adult pre-filled glycerin applicator: same label as the solid, nothing to handle.
Our verdict: The liquid format exists to remove the suppository from the suppository, and the 4 count is the right way to buy it: enough for occasional use, about $1.40 per applicator, and the same label as the solid in every line that matters. If you have avoided this shelf because of the solid, this is the product that changes that.
Verified: Labeled active: glycerin, liquid, single-use pre-filled applicator, 4 per box. Drug Facts label: for relief of occasional constipation; generally produces a bowel movement in 15 minutes to 1 hour; 6 and over, under 6 ask a doctor. Live at $5.58 on Amazon, verified via the Creators API on September 5, 2026.
Same medicine, different delivery. Fleet Liquid Glycerin Suppositories deliver glycerin from a small pre-filled applicator with a rounded tip: insert, squeeze, withdraw, discard. The Drug Facts label reads relief of occasional constipation, generally produces a bowel movement in 15 minutes to 1 hour, stimulant-free, adults and children 6 years and over, under 6 ask a doctor. The listing title does not state the glycerin amount per applicator; the panel does.
Stop lines: rectal bleeding, no bowel movement after use, or use beyond 1 week means ask a doctor. Owners consistently report the tip is comfortable and the squeeze is easy, and that the applicator is the format they would choose for an older relative. The step-by-step, which differs slightly from the solid, is in how to use a rectal suppository; the solid alternatives are ranked in the best glycerin suppositories for adults.
Who should buy it
Adults who want glycerin without a solid suppository, and caregivers helping someone else.
What we don't like

Fleet Liquid Glycerin Suppositories, 4 applicators (3 pack)
Fleet
Twelve adult applicators in one order; no per-use saving over the single box.
Our verdict: The 3 pack is the single box three times, at about $1.45 per applicator, five cents more than buying one box. There is no bulk discount here. Buy it if you already use liquid glycerin and want a dozen on hand; buy the single box to try the format.
Verified: Labeled active: glycerin, liquid, single-use pre-filled applicators, 4 per box, 3 boxes. Same Drug Facts label as the single box. Live at $17.37 on Amazon, verified via the Creators API on September 5, 2026.
Convenience, not savings. The Fleet Liquid Glycerin 3 pack is three boxes of 4, same label: occasional constipation, 15 minutes to 1 hour, ages 6 and over.
Stop lines and age lines apply. If you find you are using liquid glycerin regularly, the label's 1 week line is the cue to talk to a doctor, and suppository vs oral laxative explains the products a doctor may discuss for longer-term use.
Who should buy it
Caregivers or established liquid glycerin users who want a dozen in one order.

Worth noting

Fleet Liquid Glycerin Suppositories, larger pack
Fleet
Fleet's larger liquid glycerin listing; the title does not state how many applicators.
Our verdict: This listing is the same applicator in what Amazon presents as a larger pack, but the title does not state the count, so we cannot compute a per-use price or tell you whether it beats the 3 pack. It ranks below both counted listings for that reason alone.
Verified: Labeled active: glycerin, liquid, single-use pre-filled applicators, stimulant-free per the listing title. Same Drug Facts label. Count not stated on the listing title. Live at $22.32 on Amazon, verified via the Creators API on September 5, 2026.
Undisclosed quantity. The Fleet Liquid Glycerin larger pack carries the standard label: occasional constipation, fast and effective, stimulant-free, 15 minutes to 1 hour, ages 6 and over.
Label lines apply. For the whole glycerin shelf with every published count, see the best glycerin suppositories.
Who should buy it
Established users who have checked the count on the listing page and found it favorable.
What we don't like
Count not on the listing title, so no per-use figure.

Pedia-Lax Liquid Glycerin Suppositories, 6 count
Pedia-Lax (Fleet)
The child-sized applicator, labeled ages 2 to 5, ask a doctor under 2.
Our verdict: The pediatric liquid is the reason the liquid format exists at all: a small child and a solid suppository do not mix, and the applicator is the format parents consistently report works. Label covers ages 2 to 5, sends under 2 to a doctor, and the pediatrician decides whether a laxative is appropriate in the first place.
Verified: Labeled active: glycerin, liquid, pediatric pre-filled applicator, 6 per box. Drug Facts label: for relief of occasional constipation in children ages 2 to 5; under 2 years, ask a doctor. Live at $12.81 on Amazon, verified via the Creators API on September 5, 2026.
Liquid first, for children. Pedia-Lax Liquid Glycerin Suppositories are Fleet's pediatric line: a smaller pre-filled applicator, labeled for relief of occasional constipation in children ages 2 to 5, under 2 ask a doctor.
Stop lines mean a call to the pediatrician. The kids shelf, including the solid pediatric alternatives, is ranked in the best glycerin suppositories for kids, and the brand write-up is our Pedia-Lax review.
Who should buy it
Parents of a 2 to 5 year old whose pediatrician has approved a glycerin suppository.
What we don't like
About $2.14 per use, and a label window of 2 to 5 only.

- Easiest format for a young child
Worth noting

- Ask a doctor under 2
Pedia-Lax Liquid Glycerin Suppositories, 6 count (3 pack)
Pedia-Lax (Fleet)
Eighteen pediatric applicators at about $1.17 each, a real saving over the single box.
Our verdict: Unlike the adult 3 pack, the pediatric 3 pack is a genuine discount: about $1.17 per applicator against $2.14. Whether 18 pediatric applicators make sense depends entirely on what the pediatrician has anticipated; for occasional use, one box will expire first.
Verified: Labeled active: glycerin, liquid, pediatric pre-filled applicator, 6 per box, 3 boxes. Drug Facts label: children ages 2 to 5; under 2 ask a doctor. Live at $21.11 on Amazon, verified via the Creators API on September 5, 2026.
The pediatric bulk buy. The Pedia-Lax Liquid Glycerin 3 pack is three boxes of 6, same label: ages 2 to 5, occasional constipation, under 2 ask a doctor.
The pediatrician decides; the label's 1 week line applies to a child as it does to an adult. If the question has become whether a child should be on any laxative regularly, the best kids laxatives covers the oral products a pediatrician may discuss.
Who should buy it
Families whose pediatrician has anticipated more than one box of pediatric glycerin.
What we don't like
Eighteen applicators outlast most children's needs and the label's age window.
- Active ingredient
- Glycerin (liquid), pediatric
- Strength
- Not on the listing title

What we like
- About half the single-box cost per use
- Same clear pediatric label
Worth noting
- Quantity outlasts most needs
Fleet Glycerin Suppositories, 50 count (solid)
Fleet
The solid jar, on this page so the cost of the liquid format is honest: 9 cents a dose.
Our verdict: The solid is on a liquid page for one reason: to show what the liquid costs. Fifty adult 2 g suppositories for $4.29 is about 9 cents each, against $1.40 for the applicator. If handling a solid is not a problem for you, this is the product to buy, and the rest of this page is not for you.
Verified: Labeled active: glycerin 2 g per adult solid suppository, 50 per jar. Drug Facts label: for relief of occasional constipation; 15 minutes to 1 hour; 6 and over, under 6 ask a doctor. Live at $4.29 on Amazon, verified via the Creators API on September 5, 2026.
The comparison that keeps this page honest. Fleet Glycerin Suppositories, 50 count, is the solid adult jar: glycerin 2 g, occasional constipation, 15 minutes to 1 hour, ages 6 and over. Same active, same label window, same stop lines as every liquid above.
The solid's own drawback is heat: owners consistently report the jar softens in a warm bathroom, which a short spell in the refrigerator fixes. Full write-up: the Fleet Glycerin Suppositories review.
Who should buy it
Anyone for whom a solid suppository is not a problem.
What we don't like
Loose in a jar and softens in heat, which is the liquid's whole argument.

What we like
- About 9 cents a dose

Worth noting
- Solid to handle
- Softens in heat
What you'll need
The six things that go in the same cart as a suppository: the pharmacy-standard glycerin, a daily stool softener, an enema for the nights nothing else works, witch hazel wipes, sitz salts, and a barrier ointment. Prices are approximate at time of writing.

How we chose
This page covers every glycerin product on Amazon sold as a pre-filled liquid applicator, all of which are Fleet or Fleet's Pedia-Lax line, plus the Fleet solid jar as the reference for what the liquid format costs. For each we recorded the format, the ages the label covers, the count where the listing title states it, and the price live on Amazon on September 5, 2026 via the Creators API. Cost per use is computed only where both price and count are published. No listing title states the glycerin amount per applicator, and we do not guess it; the Drug Facts panel carries it. Owner and caregiver reports were weighed for consistency on the practical question of ease of use.
Compliance: every product is an OTC drug and we quote its label's Uses and Directions only. Adult liquid glycerin covers ages 6 and over with under 6 sent to a doctor; pediatric covers 2 to 5 with under 2 sent to a doctor; we never dose beyond those lines. The stop lines shared by every glycerin label, rectal bleeding, no bowel movement after use, use beyond 1 week, are repeated on every card. For any child, the pediatrician decides. We are a research and verification desk, not a pharmacy, and nothing here is medical advice. No brand paid for a placement.
Questions, answered
What is a liquid glycerin suppository?
Glycerin, the same active as a solid glycerin suppository, delivered from a small single-use pre-filled applicator. Insert the tip, squeeze, withdraw and discard. The Drug Facts label is the same as the solid's: relief of occasional constipation, a bowel movement generally in 15 minutes to 1 hour, stimulant-free, the same age lines and the same stop lines.
What is the best liquid glycerin suppository?
Fleet Liquid Glycerin Suppositories, 4 applicators for $5.58 at our September 5, 2026 check, about $1.40 per use. It and the Pedia-Lax pediatric version are the entire liquid glycerin shelf on Amazon. For a child aged 2 to 5, Pedia-Lax Liquid Glycerin, 6 for $12.81.
Does liquid glycerin work faster than a solid suppository?
The labels state the same window: generally produces a bowel movement in 15 minutes to 1 hour. The liquid does not need to soften in place, which owners sometimes describe as feeling quicker, but the label makes no such distinction and neither do we.
How much does liquid glycerin cost compared with a solid?
About $1.40 per applicator for the Fleet 4 count, against about 9 cents per suppository for the Fleet 50 count solid jar at our September 5, 2026 check. The 3 pack does not lower the liquid's per-use cost; the pediatric 3 pack does, to about $1.17.
Can children use liquid glycerin suppositories?
The adult Fleet liquid covers ages 6 and over and says ask a doctor under 6. The pediatric Pedia-Lax liquid covers ages 2 to 5 and says ask a doctor under 2. For any child, the pediatrician decides whether a laxative is appropriate and which one.
How much glycerin is in a liquid glycerin applicator?
No liquid glycerin listing title on Amazon states the amount per applicator, so we do not print one. The Drug Facts panel on the box does, and that is where to read it.
What if the liquid glycerin suppository does not work?
The label is the same as the solid's: stop use and ask a doctor if you fail to have a bowel movement after use or if you have rectal bleeding. Do not use a second applicator on your own.
