Buy the 50 count jar at $4.29. Glycerin 2 g per suppository, a Drug Facts label that reads 15 minutes to 1 hour, and about 9 cents a dose. The 100 count jar is cheaper still per unit, the liquid applicator is the same active for people who will not use a solid, and the only real reasons to look elsewhere are individually wrapped units (NeilMed) or a stimulant (Dulcolax). Prices verified via the Amazon Creators API on September 5, 2026.

Buy Fleet Glycerin Suppositories, 50 count, at $4.29 (verified via the Amazon Creators API on September 5, 2026). It is the adult glycerin suppository the entire category is defined by: 2 g of glycerin per suppository, a Drug Facts label that states relief of occasional constipation and a bowel movement generally within 15 minutes to 1 hour, and a cost per dose of about 9 cents ($4.29 divided by 50). If you use them more than a few times a year, the 100 count jar at $7.23 brings that to about 7 cents. If a solid suppository is the reason you have avoided this shelf, Fleet Liquid Glycerin Suppositories put the same active in a pre-filled applicator at $5.58 for 4.
Fleet is the brand pharmacists mean when they say glycerin suppository, and this review is about what that jar actually does, what the label says, and where it falls short. Glycerin is hyperosmotic: it draws water into the lower bowel and softens the stool that is already there, without stimulating the bowel wall. That is why every glycerin label reads the same 15 minutes to 1 hour and why glycerin is the first thing to try before a stimulant. The product's weaknesses are real but practical: the jar is not individually wrapped, the suppositories soften in a warm bathroom, and the label does not cover children under 6 at all. We compare it below against the two credible reasons to buy something else, a wrapped glycerin from NeilMed and a bisacodyl stimulant from Dulcolax.
This is an over-the-counter drug with a Drug Facts panel, and we quote it rather than improvise around it. The label says laxatives are for occasional constipation; to ask a doctor before use if you have stomach pain, nausea or vomiting, or a sudden change in bowel habits lasting over 2 weeks; to stop and ask a doctor if you have rectal bleeding or no bowel movement after use; and not to use a laxative for more than 1 week unless a doctor tells you to. We read labels and verify listings; we are not clinicians, nothing here is medical advice, and no brand has paid for a placement.

The short version
- Our Pick: Fleet Glycerin Suppositories, 50 count jar, $4.29 at our September 5, 2026 check. Glycerin 2 g, 15 minutes to 1 hour on the label, about 9 cents a dose.
- Best per-dose price in the line: the 100 count jar at $7.23, about 7 cents a dose. The 50 count 3-pack at $13.07 is about 9 cents, no cheaper than a single jar.
- Same active, no solid to handle: Fleet Liquid Glycerin, 4 pre-filled applicators for $5.58, about $1.40 each.
- The two honest reasons to buy elsewhere: NeilMed for individually wrapped glycerin at about 31 cents a dose, and Dulcolax bisacodyl 10 mg if a doctor is fine with a stimulant.
- Label ages: adults and children 6 and over; under 6, ask a doctor. Rectal bleeding, no bowel movement after use, or more than 1 week of use all mean stop and ask a doctor.

The Fleet glycerin line and its two benchmarks. Strengths and counts are as stated on the listing title or the Drug Facts label; where the title states no count, we say so. Prices verified via the Amazon Creators API on September 5, 2026. Cost per dose is computed only where the listing states both price and count.
Fleet Glycerin Suppositories, 50 count
Fleet
The reference adult glycerin suppository: 2 g, 15 minutes to 1 hour, about 9 cents a dose.
Our verdict: This is the jar. Two grams of glycerin per suppository, the standard adult strength, at about 9 cents a dose, from the brand that defines the category. The label covers adults and children 6 and over and sends anyone under 6 to a doctor. Buy it first; the rest of this page is about the edge cases.
Verified: Labeled active: glycerin 2 g per adult suppository, 50 per jar. Drug Facts label: for relief of occasional constipation; generally produces a bowel movement in 15 minutes to 1 hour. Live at $4.29 on Amazon, verified via the Creators API on September 5, 2026.
What it is. The Fleet Glycerin Suppositories, 50 count jar holds fifty solid, bullet-shaped adult suppositories of glycerin 2 g each. The Drug Facts label lists one use, relief of occasional constipation, and states that it generally produces a bowel movement in 15 minutes to 1 hour. Directions: adults and children 6 years and over, 1 suppository once daily or as directed by a doctor; children under 6, ask a doctor. Glycerin is hyperosmotic, meaning it works by drawing water into the lower bowel and softening what is already there rather than by stimulating the bowel wall, which is the reason it sits ahead of bisacodyl on every page of this site.
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 lasting over 2 weeks. Stop use and ask a doctor if you have rectal bleeding or fail to have a bowel movement after use, because those can be signs of a serious condition. Do not use a laxative for more than 1 week unless directed by a doctor. Owners consistently report one practical thing the label does not: the jar suppositories soften in a warm bathroom and can arrive soft in summer shipping. Chilling the jar briefly before use firms them; our guide on what to do when a suppository has melted covers it. For the field around this product, see the best glycerin suppositories, and for the timing question, how long a glycerin suppository takes to work.
Who should buy it
Buy the 50 count jar if you are an adult with occasional constipation who wants relief within the hour without a stimulant, and you would rather keep a jar in the cabinet than buy a small box each time. It is the correct first purchase on this shelf.
What we don't like
The suppositories are loose in a jar rather than individually wrapped, they soften in heat, and the label offers nothing for children under 6 except ask a doctor. The listing title does not print the 2 g strength; the Drug Facts panel does.

Worth noting

Fleet Glycerin Suppositories, Adult Jar, 100 count
Fleet
The same adult 2 g suppository in a 100 count jar, about 7 cents a dose.
Our verdict: The 100 count jar is the same suppository at a lower unit price, about 7 cents against 9. It is the right buy for a household with more than one occasional user or for anyone whose doctor has them using glycerin regularly. The trade is a bigger jar of loose suppositories that will outlast a casual user's needs.
Verified: Labeled active: glycerin 2 g per adult suppository, 100 per jar per the listing title. Same Drug Facts label as the 50 count: occasional constipation, 15 minutes to 1 hour. Live at $7.23 on Amazon, verified via the Creators API on September 5, 2026.
Same suppository, bigger jar. The Fleet Glycerin Suppositories, Adult Jar, 100 count is the same adult 2 g glycerin suppository under the same Drug Facts label: occasional constipation, 15 minutes to 1 hour, adults and children 6 and over, under 6 ask a doctor. At $7.23 (verified via the Amazon Creators API on September 5, 2026) the cost per dose is about 7 cents ($7.23 divided by 100), the lowest of any product on this page.
Everything else is identical to the pick, including the weaknesses: loose in a jar, softens in heat, and no direction for children under 6. The 100 count 2-pack at $19.01 is about 10 cents a dose ($19.01 divided by 200), which is more than a single 100 count jar, so buy two jars separately rather than the bundle.
Who should buy it
Buy the 100 count if more than one adult in the house uses glycerin suppositories, or if a doctor has directed regular use. For a single occasional user, the 50 count is the better fit.
What we don't like
A hundred loose suppositories is more than most people will use before the expiration date, and the 2-pack bundle of this jar costs more per dose than buying jars singly.
- Active ingredient
- Glycerin
- Strength
- 2 g per suppository (adult, per the Drug Facts label)
- Count
- 100
- Form
- Solid rectal suppository, jar
- Label ages
- 6 years and over; under 6 ask a doctor
- Cost per dose
- $0.07 ($7.23 divided by 100)
- Packaging
- Jar, not individually wrapped
What we like
- Lowest cost per dose in the Fleet line at about 7 cents
- Identical active, strength and label to the 50 count
- Sensible for multi-user households
Worth noting
- Too many for a single occasional user before expiry
- Same loose-jar, softens-in-heat packaging
Fleet Glycerin Suppositories, 50 count, Pack of 3
Fleet
Three 50 count jars at about 9 cents a dose, no cheaper than one jar but sealed separately.
Our verdict: The 3-pack exists for people who want three sealed jars rather than one open one, for a second bathroom, a travel bag, or an elderly parent's cabinet. At $13.07 for 150 it is about 9 cents a dose, the same as a single jar, so it saves nothing per unit. The 100 count jar is the cheaper route to volume.
Verified: Labeled active: glycerin 2 g per adult suppository, three jars of 50 per the listing title, 150 total. Same Drug Facts label as the single jar. Live at $13.07 on Amazon, verified via the Creators API on September 5, 2026.
Three sealed jars, one price. The Fleet Glycerin Suppositories, 50 count, Pack of 3 is three of the standard 50 count jars in one order. At $13.07 (verified via the Amazon Creators API on September 5, 2026) that is about 9 cents per suppository ($13.07 divided by 150), effectively the same as buying one jar at $4.29. The label, the strength and the directions are unchanged.
Storage is the practical issue with three jars: glycerin suppositories soften in heat, and a jar kept sealed in a cool cabinet holds its shape far better than one opened and left on a warm counter. Our guide on how to store suppositories covers what the label says and what owners consistently report.
Who should buy it
Buy the 3-pack if you want sealed jars in more than one place, a home cabinet, a travel bag and a second household, and you do not mind paying the single-jar rate to get them.
What we don't like
No per-dose saving over a single 50 count jar, and 150 loose suppositories is a lot of expiration-date exposure for one household.
- Active ingredient
- Glycerin
- Strength
- 2 g per suppository (adult, per the Drug Facts label)
- Count
- 150 (three jars of 50)
- Form
- Solid rectal suppository, jars
- Label ages
- 6 years and over; under 6 ask a doctor
- Cost per dose
- $0.09 ($13.07 divided by 150)
- Packaging
- Three sealed jars
What we like
- Three sealed jars for three locations
- Same label and strength as the single jar
- One order instead of three
Worth noting
- No per-dose discount over a single jar
- The 100 count jar is cheaper per unit
Fleet Liquid Glycerin Suppositories, 4 applicators
Fleet
Glycerin in a single-use pre-filled applicator, same label window, no solid to handle.
Our verdict: Liquid glycerin removes the one objection people have to the jar, which is the suppository itself. Each applicator is pre-filled, inserted, squeezed and thrown away, and the label carries the same 15 minutes to 1 hour. At about $1.40 per use it is fifteen times the jar's cost per dose, and for the people who need the format, that is a fair trade.
Verified: Labeled active: glycerin, liquid, single-use pre-filled applicator, 4 per box. Drug Facts label: relief of occasional constipation; generally produces a bowel movement in 15 minutes to 1 hour. Live at $5.58 on Amazon, verified via the Creators API on September 5, 2026.
The same active, a different delivery. Fleet Liquid Glycerin Suppositories put glycerin in a small pre-filled applicator with an insertion tip. Nothing is unwrapped, warmed or held in the hand. 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, 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 on the box does. Same stop lines as the solid: rectal bleeding, no bowel movement after use, or more than 1 week of use all mean ask a doctor. The full format field, including the pediatric Pedia-Lax version, is in the best liquid glycerin suppositories.
Who should buy it
Buy the liquid if a solid suppository is the reason you have avoided glycerin, or if you are helping another adult and want the simplest single-use format.
What we don't like
About $1.40 per use, only 4 per box, and the listing title does not print the glycerin amount per applicator.
- Active ingredient
- Glycerin (liquid)
- Strength
- Not stated on the listing title; on the Drug Facts panel
- Count
- 4 single-use applicators
- Form
- Pre-filled rectal applicator
- Label ages
- 6 years and over; under 6 ask a doctor
- Cost per dose
- $1.40 ($5.58 divided by 4)
- Packaging
- Boxed, each applicator sealed
What we like
- No solid suppository to handle or warm
- Same 15 minutes to 1 hour on the label
- Sealed, single-use, travels well
Worth noting
- About fifteen times the jar's cost per dose
- Only 4 per box
- Amount per applicator not on the listing title
NeilMed Glycerin Laxative Suppositories, 30 count
NeilMed
The wrapped glycerin alternative, about 31 cents a dose, for travel or a shared cabinet.
Our verdict: NeilMed answers the one complaint about Fleet's jar: each suppository is individually wrapped. That costs about 31 cents a dose against Fleet's 9. For a travel bag, a shared bathroom, or a hot climate where loose suppositories soften, the wrapper is worth it; for a home cabinet, it is not.
Verified: Labeled active: glycerin (strength per suppository not stated on the listing title). Individually wrapped, 30 per box per the title. Drug Facts label: relief of occasional constipation. Live at $9.19 on Amazon, verified via the Creators API on September 5, 2026.
The wrapped benchmark. The NeilMed Glycerin Laxative Suppositories are the same active as Fleet in individually wrapped units, 30 to the box per the listing title. The label use is relief of occasional constipation. NeilMed is best known for saline rinses, and its laxative line carries the same packaging discipline. At $9.19 (verified via the Amazon Creators API on September 5, 2026) the cost per dose is about 31 cents ($9.19 divided by 30).
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.
Who should buy it
Buy NeilMed instead of Fleet if you need individually wrapped glycerin suppositories for travel, a shared cabinet, or a bathroom that gets hot.
What we don't like
About 31 cents a dose against Fleet's 9, and the listing title does not state the glycerin amount per suppository.
- Active ingredient
- Glycerin
- Strength
- Not stated on the listing title; on the Drug Facts panel
- Count
- 30 (per listing title)
- Form
- Solid rectal suppository, individually wrapped
- Label ages
- Per the Drug Facts panel
- Cost per dose
- $0.31 ($9.19 divided by 30)
- Packaging
- Individually wrapped, boxed
What we like
- Individually wrapped, the thing Fleet's jar lacks
- Count stated on the listing
- Same active and label use
Worth noting
- Roughly three times Fleet's cost per dose
- Strength not on the listing title
Dulcolax Stimulant Laxative Medicated Suppositories, 4 count
Dulcolax
Bisacodyl 10 mg, the stimulant suppository for when glycerin has not been enough.
Our verdict: Dulcolax is not a glycerin competitor so much as the next step. Bisacodyl 10 mg acts on the bowel wall rather than drawing water in, the label carries the same 15 minutes to 1 hour, and it is explicit that this is a stimulant for occasional use. If glycerin has not produced a bowel movement, the label says ask a doctor; if the doctor is fine with a stimulant, this is the reference one.
Verified: Labeled active: bisacodyl 10 mg per suppository, stimulant laxative, 4 per box. Drug Facts label: relief of occasional constipation; generally produces a bowel movement in 15 minutes to 1 hour. Live at $5.48 on Amazon, verified via the Creators API on September 5, 2026.
Different mechanism, same window. Dulcolax Stimulant Laxative Medicated Suppositories contain bisacodyl 10 mg. Where glycerin is hyperosmotic, bisacodyl is a stimulant laxative acting on the bowel itself. The Drug Facts label reads relief of occasional constipation and 15 minutes to 1 hour. Directions: adults and children 12 and over, 1 suppository in a single daily dose; children 6 to under 12 have a separate reduced direction printed on the label; under 6, ask a doctor. At $5.48 (verified via the Amazon Creators API on September 5, 2026) for 4, each is about $1.37 ($5.48 divided by 4).
Rectal bleeding or no bowel movement after use means stop and ask a doctor, on this label as on every laxative label. The brand deep dive is our Dulcolax suppositories review.
Who should buy it
Buy Dulcolax instead of Fleet only if glycerin has not worked for you and a doctor is fine with an occasional stimulant suppository.
What we don't like
It is a stimulant with cramping listed as a possible effect, about $1.37 a dose, and its under 6 line is ask a doctor rather than a direction.
- Active ingredient
- Bisacodyl
- Strength
- 10 mg per suppository
- Count
- 4
- Form
- Solid rectal suppository, individually sealed
- Label ages
- 12 and over; 6 to under 12 per label; under 6 ask a doctor
- Cost per dose
- $1.37 ($5.48 divided by 4)
- Packaging
- Boxed, sealed
What we like
- Reference bisacodyl 10 mg from the category brand
- Same 15 minutes to 1 hour on the label
- Box of 4 matches the occasional-use label
Worth noting
- Stimulant; cramps and discomfort listed as possible effects
- About $1.37 per dose
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 review is built on the Drug Facts panel and the live listing. For every Fleet SKU we recorded the active ingredient and strength where the title or label states it, the count, the form (solid jar suppository or pre-filled liquid applicator), the label's age directions, and the Amazon price on September 5, 2026 via the Creators API. Cost per dose is shown only where the listing title gives both a price and a count, with the division shown. Owner reports were weighed for consistency on the things a label cannot tell you: whether the jar arrives with softened suppositories in summer, whether the jar seal holds, and whether the applicator tip on the liquid version is comfortable.
Compliance for this shelf: we quote the label's Uses and Directions and nothing beyond them. We never suggest a dose the label does not print, we carry every age cut-off, and we repeat the stop lines every laxative label shares: rectal bleeding, no bowel movement after use, or use beyond 1 week mean stop and ask a doctor. Laxatives are for occasional use. For any child, the pediatrician decides. We are a research and verification desk, not a pharmacy or a clinic, and nothing on this page is medical advice. No brand paid for a placement and none saw this review before publication.
Questions, answered
Are Fleet Glycerin Suppositories good for constipation?
They are the reference adult glycerin suppository. The Drug Facts label lists relief of occasional constipation and states that it generally produces a bowel movement in 15 minutes to 1 hour. Glycerin is hyperosmotic, drawing water into the lower bowel rather than stimulating it, which is why it is the first suppository to try. At $4.29 for 50 at our September 5, 2026 check, it is about 9 cents a dose.
How long does a Fleet Glycerin Suppository take to work?
The Drug Facts label states that it generally produces a bowel movement in 15 minutes to 1 hour. The liquid glycerin applicator carries the same window. If you have no bowel movement after use, the label's instruction is to stop and ask a doctor, because that can be a sign of a serious condition.
How many grams of glycerin are in a Fleet adult suppository?
The Drug Facts panel states 2 g of glycerin per adult suppository. The Amazon listing title does not print the strength, so read the panel on the jar. Pediatric glycerin suppositories from other brands are a smaller size with their own labels.
Can a child use Fleet Glycerin Suppositories?
The adult label covers adults and children 6 years and over and says ask a doctor for children under 6. It does not direct use in younger children, and neither do we. For ages 2 to 5, Pedia-Lax Liquid Glycerin Suppositories are the Fleet product whose label covers the age, and the pediatrician decides whether any laxative is appropriate.
Is the 100 count jar a better buy than the 50 count?
Per dose, yes: about 7 cents ($7.23 divided by 100) against about 9 cents ($4.29 divided by 50) at our September 5, 2026 check. For a single occasional user, the 50 count is still the sensible purchase, because a hundred suppositories will reach their expiration date first. The 50 count 3-pack at $13.07 is about 9 cents a dose, no cheaper than one jar.
Can I use a Fleet Glycerin Suppository every day?
Not without a doctor. The label says not to use laxatives for more than 1 week unless directed by a doctor, and the listed use is occasional constipation. If you need one regularly, that is the label's own signal to talk to a clinician about why.
What do I do if the suppositories arrived soft or melted?
Glycerin softens in heat, and owners consistently report the jar can arrive soft in summer. Cool the sealed jar in the refrigerator for a short time to firm them, and do not use one that has lost its shape. Our guide on what to do when a suppository has melted covers storage and re-firming.
Fleet Glycerin or Dulcolax: which should I use?
Fleet glycerin first. It is not a stimulant and its label lists none of the cramping or discomfort the bisacodyl label does. Dulcolax is bisacodyl 10 mg, a stimulant laxative with the same 15 minutes to 1 hour on the label, for occasional use. If glycerin has not produced a bowel movement, the label says ask a doctor; if a doctor is fine with a stimulant, Dulcolax is the reference product.
