How to Use a Rectal Suppository: Laxative, Hemorrhoidal and Fever Types

Prepare: wash your hands, and if the suppository feels soft in its wrapper, chill it in the refrigerator for 15 to 30 minutes or under cold running water; a firm suppository inserts cleanly and a soft one smears. Unwrap it and moisten the pointed end with a little water. Position: lie on your left side, lower leg straight, upper knee bent toward your chest. Insert: lift the upper buttock, breathe out, and push the suppository in pointed end first with your index finger until it passes the muscle at the opening and you feel it move freely, about 1 inch for an adult. Hold: withdraw your finger, squeeze your buttocks together for a few seconds, and stay lying down for about 15 minutes.

That routine is identical for glycerin, bisacodyl, hemorrhoidal and acetaminophen suppositories. Where they differ is what the label directs next, and that is the rest of this page. If you want the full flagship walkthrough with the vaginal route and child technique, it is in how to insert a suppository.

The Fleet Glycerin Suppositories Drug Facts label states glycerin 2 g per adult suppository, lists the use as 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. The jar works out to about 9 cents a suppository ($4.29 divided by 50 at our September 5, 2026 check), which is why it is the reference product on the shelf. The individually wrapped alternative is NeilMed Glycerin Suppositories at $9.19, which owners prefer for travel and warm bathrooms.

After insertion, hold it as long as the urge allows within the first 15 minutes; glycerin works by drawing water into the lower bowel and softening what is there, and owners consistently report a more complete result when the suppository has had time to dissolve. 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; do not use laxative products for more than 1 week unless directed by a doctor. Timing in more detail is in how long a glycerin suppository takes to work.

Dulcolax Medicated Suppositories contain bisacodyl 10 mg, a stimulant laxative. The label states it generally produces a bowel movement in 15 minutes to 1 hour, the same window as glycerin, but the mechanism is different: bisacodyl acts on the bowel wall rather than drawing in water, and the label lists abdominal discomfort, faintness, rectal burning and mild cramps as possible effects. Directions: adults and children 12 years and over, 1 suppository in a single daily dose; children 6 to under 12 years, one half suppository in a single daily dose; children under 6, ask a doctor. It is one of the few labels on this shelf that directs cutting a suppository.

Insertion is the standard routine, and the label's own note is that the suppository should be inserted well into the rectum. The stimulant caveat matters: every stimulant laxative label says occasional use, and the 1-week line applies. Most pharmacists and the labels themselves put glycerin first and bisacodyl second, for when glycerin has not worked and a doctor is fine with a stimulant. The comparison is in glycerin vs bisacodyl suppositories, and the bisacodyl field is ranked in the best bisacodyl suppositories.

Fleet Liquid Glycerin Suppositories put the same glycerin into a small squeeze bottle with a soft, pre-lubricated tip, 4 to a box at $5.58 (verified via the Amazon Creators API on September 5, 2026), about $1.40 each. The routine changes because there is no solid to handle: remove the protective cap, lie on your side with the upper knee bent, gently insert the tip into the rectum with the bottle pointed slightly toward your back, squeeze until the bottle is nearly empty, and withdraw it while still squeezing so the liquid stays in. Discard the bottle. The label carries the same 15 minutes to 1 hour window and the same directions and warnings as the solid suppository, including 6 and over with under 6 sent to a doctor.

Who it suits: people who find a solid suppository awkward, anyone with limited hand dexterity, and caregivers. What owners report: the tip can feel firmer than expected, so a slow insertion matters; and the small volume means little leakage compared with an enema. It is not an enema. The liquid glycerin field is ranked in the best liquid glycerin suppositories.

A hemorrhoidal suppository is not meant to produce a bowel movement; it is a protectant and, in the Preparation H formula, a vasoconstrictor that melts and coats swollen internal tissue. The Preparation H Suppositories Drug Facts label lists cocoa butter as a protectant and phenylephrine as a vasoconstrictor; its uses are temporary relief of itching, burning and discomfort of hemorrhoids and temporary shrinking of hemorrhoidal tissue. Directions: adults, insert one suppository rectally up to 4 times daily, especially at night, in the morning, or after each bowel movement; children under 12, ask a doctor.

Because the base is cocoa butter, these melt at close to body temperature and will leak; the label's timing (night, morning, after a bowel movement) is designed around that, and owners keep them refrigerated so they are firm enough to insert. Stop lines on the label: if bleeding occurs, or the condition worsens or does not improve within 7 days, stop use and ask a doctor.

FeverAll acetaminophen suppositories exist for one situation: a child who cannot keep oral medicine down. The rectal lining absorbs acetaminophen into the bloodstream, which is why these are dosed by age like any fever reducer. The FeverAll infant strength is 80 mg and its label covers ages 6 to 36 months, sending infants under 6 months to a doctor; the children's strength is 120 mg, labeled for ages 3 to 6; the junior strength is 325 mg, labeled for ages 6 to 12. The box prints the dosing interval and the daily maximum for each age, and that box, not this page, is the dose. Insertion is the standard routine at pediatric depth, about half an inch, holding the buttocks together afterward because a small child will push reflexively.

The label's stop lines: stop use and ask a doctor if fever gets worse or lasts more than 3 days, if pain gets worse or lasts more than 5 days, or if new symptoms appear, and acetaminophen carries a liver warning about combining products. The American Academy of Pediatrics says any fever in an infant under 3 months is a reason to call the doctor before giving anything at all. The pediatrician decides. Strengths and ages are compared in the best acetaminophen suppositories.
