When you are blocked up and uncomfortable, you want the fastest, gentlest way to get moving again — and a suppository acts in 15 to 60 minutes. This guide covers five options, from glycerin to bisacodyl 10mg, so you can match onset time and price to your needs.
This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
To get the right laxative suppository, match two things to your situation: the active ingredient (the medicine that does the work) and how fast it starts working. That way you get fast relief at home or a steady option for a medical condition.
Top Picks
How To Choose The Best Laxative Suppository
You pick a suppository based on two things: how fast you need relief and how gentle you want it to be. The active ingredient (the medicine inside) controls both, so it helps to know which one you are using.
Glycerin vs. Bisacodyl
Glycerin suppositories pull water into the stool to soften it, so they suit occasional constipation. Bisacodyl (a stimulant laxative) works by prompting your intestines to move — you will see it listed as 10mg on several labels in this guide.
The trade-off is speed versus gentleness. Bisacodyl tends to act within 15 to 60 minutes, while glycerin is often described as working in a similar window. The reviews across these picks suggest that most people notice a difference in cramping between the two, which is worth weighing if you are sensitive.
Onset Time And Storage
Onset time is the number buyers check first, and it is usually printed right on the box. Some picks here list 15 to 60 minutes; others report relief closer to 10 to 15 minutes. Either way, plan to be near a bathroom once you use one.
Storage matters more than most people expect. Heat softens suppositories and can make them hard to insert, so keep them in a cool, dry place — a few reviewers specifically mentioned this. If you live somewhere warm, the fridge is a safe bet for long-term storage.

Detailed Reviews
1. Fleet Glycerin Suppositories 100 Each 2-Pack
Our pick — over 4.5★ from 600+ verified ratings; the strongest balance of quality and price.
Buyers like the quality: the glycerin holds its shape in the jar and is neither too dry nor too wet to insert comfortably. The two-pack of 100-count jars means you are set for a long stretch, which is why this is the best overall pick in this guide. The jar also keeps each suppository protected until you need it.
The one honest catch is storage. Glycerin softens in heat, so keep the jar somewhere cool — several buyers suggest the fridge if your bathroom runs warm. The jar is also larger than the small individual boxes other picks come in, so it takes up more shelf space. The package measures 3.94 x 1.97 x 1.18 inches and weighs 1.46 pounds, which is still modest for a two-pack.
What Buyers Appreciate
- Works in 15 minutes to 1 hour for occasional constipation
- Two jars of 100 each means months of supply
- Consistent texture — neither too dry nor too wet
Worth Knowing
- Should be stored in a cool place so it does not soften
- Bulk jar takes more shelf space than small boxes
- Glycerin works differently than bisacodyl — no stimulant effect for severe cases
Stock up if: you deal with occasional constipation and want a trusted, gentle option with a long supply.
Look elsewhere if: you need a stimulant laxative for a more stubborn backup — a bisacodyl pick may suit you better.
2. Dulcolax Stimulant Laxative Medicated Suppositories 16ct
The name-brand bisacodyl that gets to work in as little as 15 minutes.
Dulcolax is the brand most people already know, and that familiarity shows up in the reviews. Buyers report it acting inside 30 minutes, and the active ingredient — bisacodyl 10mg — helps increase movement in the intestines. That makes it a strong fit when you need reliable, fast relief and cannot wait around.
The comfort-shaped design is a real difference-maker here. These are made for rectal use only and are do not swallow, and the shape is meant to sit comfortably during insertion. One buyer described the brand as gentle and effective compared to alternatives that cause stomach cramps — a frequent point of comparison when weighing this pick against a generic.
The trade-off to know is the side effects. Some owners mention cramping or a stronger urge than they expected, and the reviews are mixed on that point. A few also note the individual wrapping is a little harder to peel than other brands. If you are new to bisacodyl, start with one and see how your body responds before relying on it for an important event.
Fast and dependable: the 10mg bisacodyl dose works in 15 to 60 minutes, and the 16-count box is enough for several uses.
The side-effect note: cramping is the one thing buyers mention as a mixed experience — milder than some generics, but not zero for everyone.
Reach for it when: you want a recognizable brand that offers predictable, fast relief and easy insertion.
Think twice if: you are sensitive to cramping or prefer the gentler feel of a glycerin formula.
3. Rite Aid Pharmacy Laxative Suppositories 8 Suppositories
A no-frills bisacodyl that matches the name brands at a friendlier tier.
Rite Aid’s version uses the same active ingredient as Dulcolax — bisacodyl 10mg — and promises prompt relief of constipation in 15 minutes to 1 hour. If the name brand feels like more than you need, this one does the same job for less, and it is eligible for FSA and HSA reimbursement.
The individual wrapping is a thoughtful touch. Each suppository comes sealed on its own, which keeps the medicine clean and makes it easy to grab just one. Customers note it working in 10 to 15 minutes, and the packaging is compact — the box measures 3.23 x 3.11 x 0.87 inches and weighs 0.63 ounces, so it tucks into a drawer without fuss.
The honest catch is consistency. A few reviewers point out the suppositories arriving about a third empty, which affects how well they work. It is not the norm across the reviews, but it is worth knowing before you commit to a box. If you want the extra safety margin of a brand name, this is where you would pay for it.
Same dose, lower tier: bisacodyl 10mg gives you the same stimulant action as the pricier name brand, just in a smaller 8-count box.
The gamble: quality control is the recurring note — check your box on arrival and you will know quickly whether you got a good batch.
Pick this if: you want the bisacodyl action without the brand markup, and FSA or HSA reimbursement matters to you.
4. Supppositories 10 Mg – 50 Count
The 50-count workhorse for people who need this as part of daily life.
For anyone managing a chronic or neurogenic bowel routine, the count is what matters most. That makes it the practical choice when you go through these regularly.
The package is built for handling. It measures 7.72 x 2.76 x 1.57 inches and weighs 4.23 ounces, so it is the larger format in this guide. One buyer — who has to use these — noted they can break each one in half and stretch the box twice as far. Another appreciated that you can get the medicine out of the packaging without scissors, which matters when you use these often.
The mixed point is quality consistency. Most buyers find the effectiveness excellent, but some report the quality varies from batch to batch. It is worth keeping an eye on the expiration date when your box arrives, since a 50-count supply can last a long time if you are not using it daily.
Built for volume: 50 suppositories at 10mg bisacodyl is the best fit in this guide for anyone with a medical routine.
Batch variation: effectiveness is the strong suit, but the occasional box draws fewer positive notes on quality — check yours on arrival.
Best for: people managing ongoing constipation who need a large, reliable supply they can count on.
Not ideal if: you only need a suppository now and then — a smaller count will serve you better.
5. The Magic Bullet Suppository for Constipation – Pack of 10
The one people say works almost instantly — but it comes in a small, fragile pack.
Magic Bullet earns its name in the reviews. It packs bisacodyl 10mg in a polyethylene glycol base — a water-soluble carrier that dissolves quickly — and buyers describe it working instantly and consistently. For anyone with neurogenic bowel or a routine where timing is everything, that instant action is the whole reason to choose this one.
The reputation is strong in the spinal cord injury community. One buyer who is quadriplegic found Magic Bullet through a support group and describes it as a significant step up from the brands recommended at the hospital — teammates ask about it after borrowing. That kind of word-of-mouth is rare, and it speaks to how reliably this one works.
The catch is two-fold. Shoppers say the price tier sits higher than the other picks, and the pack is small at 10 suppositories. Worse, the suppositories are fragile — a few arrived broken, which can leave you with crumbled pieces you cannot use. The expiration window can also run short on arrival, so check the date the moment it lands.
Instant action: the water-soluble base dissolves fast, and the 10mg bisacodyl dose is built for speed when you cannot wait.
Handle with care: fragility in transit and a short expiration window are the two things to watch for on delivery.
Get this if: you need instant, dependable relief — especially for a neurogenic bowel routine — and can afford the premium tier.
Choose the 50-count instead if: you want a bigger supply at a lower tier per unit and do not need lightning-fast onset.
Know the Specs
Active Ingredient: Glycerin vs. Bisacodyl
Glycerin works by drawing water into the stool, which softens it — ideal for occasional constipation. Bisacodyl, listed as 10mg on most of these labels, stimulates the intestines directly. That stimulant action often feels faster and stronger, which is why several picks here use it. The trade-off is that a stimulant can bring more cramping for some people.
Onset Time and Count
Onset time is the clock from insertion to relief, and it is printed on every box. This guide’s picks list anywhere from 10 minutes to 1 hour. The count matters too: a 100-count jar suits someone using these daily, while an 8-count box is plenty for occasional need. Match the count to how often you actually reach for one.
