Buy Senokot Extra Strength Senna Laxative Tablets, 36 count, at $14.12 (verified via the Amazon Creators API on September 5, 2026). Senokot is the senna brand, its Drug Facts label reads relief of occasional constipation with a bowel movement generally in 6 to 12 hours, and 36 tablets is about 39 cents each ($14.12 divided by 36). If you want the generic at a published sennoside strength, Major Senna 8.6 mg at $5.84 prints its strength in the title. For a child, the only senna product here with a children's label is Senokot Kids Gummies, and the pediatrician decides.
Senna is a stimulant laxative. The active ingredients are sennosides, plant compounds from the senna leaf that act on the bowel wall, and every senna Drug Facts label says the same things: occasional constipation, generally produces a bowel movement in 6 to 12 hours, directions by age with the youngest band sent to a doctor, and not more than 1 week unless a doctor directs. It is the overnight laxative: taken at bedtime, labeled to work by morning. It is not fast, and it is not for routine use; the label is explicit on both. Because senna is a plant extract, the shelf also carries herbal products, and some of those are labeled as supplements rather than drugs. This page says which is which as far as the listing allows, and it treats every one as a stimulant for occasional use.
The label lines, stated once. 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. Do not use for more than 1 week unless directed by a doctor. Pregnant or breast-feeding: ask a health professional before use. For a child, the pediatrician decides; senna labels direct by age band and send the youngest to a doctor. We read labels and verify listings; we are not clinicians, nothing here is medical advice, and no brand paid for a placement.

Senokot Extra Strength Senna Laxative Tablets, 36 count
Senokot
The senna brand at its higher strength, 6 to 12 hours on the label, about 39 cents a tablet.
Our verdict: Senokot is to senna what Dulcolax is to bisacodyl: the brand whose label the category copies. The Extra Strength tablet is the higher of Senokot's two strengths, with the milligrams on the panel rather than the title, 36 to the box at about 39 cents. Overnight, occasional, and clearly labeled. The right senna to buy first.
Verified: Labeled active: sennosides, stimulant laxative, Extra Strength, 36 tablets per the listing title (milligrams on the Drug Facts panel). Label: for relief of occasional constipation; generally produces a bowel movement in 6 to 12 hours; directions by age. Live at $14.12 on Amazon, verified via the Creators API on September 5, 2026.
The overnight brand. Senokot Extra Strength Senna Laxative Tablets contain sennosides, the stimulant compounds from senna leaf. The Drug Facts label reads relief of occasional constipation and generally produces a bowel movement in 6 to 12 hours, which is why the standard advice is to take it at bedtime. Directions are by age on the label; the youngest band is ask a doctor; we do not restate tablet counts.
Stimulant cautions: occasional use, not more than 1 week without a doctor, stop for rectal bleeding or no bowel movement after use, ask a health professional if pregnant or breast-feeding. Senna is one of the slowest stimulants and the suppository is the fastest; the best laxatives for fast relief puts every window on one table, and suppository vs oral laxative explains when overnight is the right answer.
Who should buy it
Adults who want the reference senna brand for occasional overnight relief.

Major Senna 8.6 mg Natural Vegetable Laxative Tablets
Major Pharmaceuticals
Sennosides 8.6 mg per tablet, the standard senna strength, printed in the title.
Our verdict: Major's senna prints what Senokot's title does not: 8.6 mg sennosides per tablet, the standard senna strength. At $5.84 a bottle it is the value senna, with the caveat that the listing does not state the count, so we cannot give a cost per tablet. Buy it if you have used senna before and want the generic at a known strength.
Verified: Labeled active: sennosides 8.6 mg per tablet, stimulant laxative, labeled for occasional constipation per the listing title. Count not on the listing title. Live at $5.84 on Amazon, verified via the Creators API on September 5, 2026.

Prunelax Ciruelax Maximum Relief Laxative Tablets
Prunelax
A senna extract tablet marketed on prune, labeled for occasional constipation; count not on the title.
Our verdict: Prunelax is senna extract sold under a prune name, and its listing is clear that the laxative is the senna and the use is occasional constipation. It is the most expensive bottle here with neither strength nor count on the title, which is why it ranks mid-table. It is a senna stimulant with a senna stimulant's cautions, whatever the fruit on the box.
Verified: Labeled: Prunelax Ciruelax Maximum Relief laxative tablets with natural senna, senna extract, for occasional constipation per the listing title. Strength and count not on the listing title. Live at $18.89 on Amazon, verified via the Creators API on September 5, 2026.

Traditional Medicinals Organic Smooth Move Laxative Capsules
Traditional Medicinals
Organic senna and licorice in a capsule from the Smooth Move tea house.
Our verdict: Smooth Move is best known as a senna tea, and the capsule is the same idea without the cup: organic senna with licorice, from an established herbal house. The listing states neither strength nor count, and whether the box carries Drug Facts or Supplement Facts is something to check on the panel. Either way, senna is a stimulant and this is occasional-use only.
Verified: Labeled: Traditional Medicinals Organic Smooth Move laxative capsules, organic senna and licorice, laxatives for constipation per the listing title. Strength and count not on the listing title. Live at $14.86 on Amazon, verified via the Creators API on September 5, 2026.

Swiss Kriss Herbal Laxative Tablets
Swiss Kriss
A long-established herbal senna tablet; the listing states adults and children, the panel states the rest.
Our verdict: Swiss Kriss is the herbal senna tablet that has been on pharmacy shelves for generations, and its listing describes it for adults and children. The title states neither strength nor count. It is a Tier B herbal product and a senna stimulant; read the panel for the age bands and for whether it carries Drug Facts or Supplement Facts, and treat it as occasional-use.
Verified: Labeled: Swiss Kriss herbal laxative tablets, gentle and natural laxatives for constipation relief for adults and children per the listing title. Strength and count not on the listing title. Live at $12.99 on Amazon, verified via the Creators API on September 5, 2026.

Senokot Kids Mixed Berry Laxative Gummies, 40 count
Senokot
Senna extract in a children's gummy with age bands on the label, 40 for $15.99.
Our verdict: The only senna product on Amazon with a children's label, from the senna brand: a mixed berry gummy with age bands on the Drug Facts panel and the youngest band sent to a doctor. About 40 cents a gummy. A stimulant is a stimulant in a child as in an adult, and the pediatrician decides whether one is appropriate at all.
Verified: Labeled active: senna extract, stimulant laxative, kids gummies, mixed berry, 40 count per the listing title. Drug Facts label: for relief of occasional constipation in children; directions by age band; younger children ask a doctor. Live at $15.99 on Amazon, verified via the Creators API on September 5, 2026.
Senna, for children, labeled. Senokot Kids Mixed Berry Laxative Gummies contain senna extract and carry a Drug Facts label with directions by age band; the youngest band is ask a doctor. We do not restate the gummy counts; the box does, and the pediatrician who named the product will.
Many pediatricians name a non-stimulant first; the shelf they choose from is in the best kids laxatives, and the pediatric suppository alternative is in the best glycerin suppositories for kids.
Who should buy it
Parents whose pediatrician has named a senna product for a child in the label's age bands.
What we don't like

Colace 2-in-1 Stool Softener Plus Stimulant Laxative Tablets, 60 count
Colace
Docusate plus a stimulant laxative in one tablet, on this page for the stimulant half.
Our verdict: The 2-in-1 pairs docusate with a stimulant laxative, and the stimulant on the panel is the reason it belongs on a senna page. It is a product a doctor names when both softening and stimulation are wanted; it is not plain Colace and not plain senna. About 28 cents a tablet, 60 to the bottle, with a stimulant's cautions.
Verified: Labeled active: docusate sodium (stool softener) plus a stimulant laxative per the listing title, 60 tablets. Drug Facts label: for relief of occasional constipation; the stimulant carries a stimulant's directions and warnings. Live at $16.69 on Amazon, verified via the Creators API on September 5, 2026.
Two actives. Colace 2-in-1 combines docusate sodium with a stimulant laxative in one tablet, 60 per bottle; the Drug Facts panel states both actives and their strengths. Its directions follow the stimulant: occasional constipation, not the days-long softening course plain docusate is for.
Stimulant cautions apply. The docusate side of the shelf is in the best stool softeners and the Colace review.
Who should buy it
Buyers whose doctor has named a softener-plus-stimulant combination.

How we chose
Every senna product in our verified Amazon catalog is on this page, plus the one combination product that pairs a stool softener with a stimulant. For each we recorded the form, the sennoside strength where the listing title states it, the count where the title states it, the price live on Amazon on September 5, 2026 via the Creators API, and cost per unit only where both price and count are published. Because senna is sold both as an OTC drug and as an herbal supplement, we note for each product what its listing describes and tell readers to check which panel the box carries; we do not assume. The brand with the clearest Drug Facts label ranks first, the generic with a printed strength second, and products that publish neither strength nor count below them.
Compliance: senna is a stimulant laxative and, where it is an OTC drug, we quote its label's Uses and Directions only: occasional constipation, 6 to 12 hours, directions by age with the youngest band sent to a doctor, and not more than 1 week without a doctor. We do not restate tablet counts by age. Herbal senna products that carry a Supplement Facts panel are dietary supplements and are described in the words their labels use; for those, These statements have not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure, or prevent any disease. Stimulant laxatives are for occasional use, never routine. 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 the best senna laxative?
Senokot Extra Strength Senna Laxative Tablets, 36 for $14.12 at our September 5, 2026 check, about 39 cents each. It is the senna brand, with a Drug Facts label that reads relief of occasional constipation with a bowel movement generally in 6 to 12 hours. For the generic with the standard 8.6 mg sennoside strength printed in the title, Major Senna is $5.84.
How long does senna take to work?
Senna Drug Facts labels state that it generally produces a bowel movement in 6 to 12 hours, which is why it is taken at bedtime for a morning result. It is not a fast laxative; glycerin and bisacodyl suppositories are labeled 15 minutes to 1 hour.
Is senna a stimulant laxative?
Yes. Its active compounds, sennosides, act on the bowel wall, and every senna Drug Facts label calls it a stimulant laxative for occasional use. Natural, gentle and vegetable on the box do not change the mechanism or the label's 1 week line.
How often can you take senna?
The label gives directions by age and says not to use for more than 1 week unless a doctor directs. It is for occasional constipation. Nightly use is the label's own cue to see a clinician.
Is senna safe for kids?
The pediatrician decides. Senokot Kids Gummies are the only senna product on Amazon with a children's Drug Facts label; directions are by age band and the youngest band is ask a doctor. Adult senna labels also direct by age and send the youngest to a doctor. A stimulant is a pediatrician's call.
Senna or bisacodyl: which is better?
Both are stimulant laxatives for occasional use with the same 1 week line. Oral senna and oral bisacodyl tablets are both labeled 6 to 12 hours. The difference in speed comes from format, not active: a bisacodyl suppository is labeled 15 minutes to 1 hour. If you want overnight and oral, either; if you want under an hour, the suppository.
Is Smooth Move or Swiss Kriss a drug or a supplement?
Check the panel on the box. Herbal senna products are sold both ways, and the listing titles for Smooth Move capsules and Swiss Kriss do not say which. If the panel is Supplement Facts, the product is a dietary supplement not approved to treat anything; if it is Drug Facts, the standard senna laxative lines apply. In both cases senna is a stimulant for occasional use.
Can I take senna while pregnant?
The label says that if you are pregnant or breast-feeding you should ask a health professional before use. We do not rank laxatives for pregnancy, and the conversation comes first.
