Fleet Enema Review: Saline, Mineral Oil and Children's, and Which One the Label Points You To

What it is. The Fleet Saline Enema is a single-use 4.5 oz bottle of sodium phosphates solution with a pre-lubricated tip. The Drug Facts label lists relief of occasional constipation and states it generally produces a bowel movement in 1 to 5 minutes. Directions: adults and children 12 years and over, 1 bottle; children 2 to under 12, use the children's product; under 2, do not use. The sodium phosphates draw water into the bowel, which is why the window is minutes and why the label is careful about who should use it.

Owners consistently report the tip is comfortable and the bottle is easy to use lying on the left side, which is the position the label's own illustration shows. If you have not tried a glycerin suppository, the label logic says that is the less involved first step; suppository vs enema lays out the decision, and the best enemas ranks the whole shelf. For the wider laxative options, the best laxatives for fast relief puts enemas beside suppositories and oral products.

The value pack. The Fleet Enema Saline, 4 bottles listing is four of the standard 4.5 oz sodium phosphates bottles. At $4.78 (verified via the Amazon Creators API on September 5, 2026) each is about $1.20 ($4.78 divided by 4). The 3-pack listing was $9.77 at the same check, about $3.26 a bottle, so the 4 pack is the volume buy and the 3-pack is the one to skip unless its price has moved.

Everything else is identical to the 2 count: the same ask-a-doctor list (sodium-restricted diet, kidney disease, heart problems, dehydration, 55 or older), the same age bands, the same stop lines. The Fleet Adult Enema 2 Pack listing at $6.99 is a separate listing of the adult saline at about $3.50 a bottle; buy the 2 count or the 4 pack instead.

What it is. The Fleet Mineral Oil Enema is a 4.5 fl oz single-use bottle of mineral oil with a pre-lubricated tip, latex free per the title. Mineral oil is a lubricant laxative: it coats and softens rather than pulling water into the bowel. The Drug Facts label lists relief of occasional constipation and states it generally produces a bowel movement in 2 to 15 minutes. Directions: adults and children 12 years and over, 1 bottle; children 2 to under 12, one-half bottle per the label; under 2, do not use.

The mineral oil label has its own lines: do not use more than one in 24 hours, stop and ask a doctor for rectal bleeding or no bowel movement after use, and not more than 1 week without a doctor. Mineral oil can leak after use, which owners consistently report and which is worth knowing before the first bottle. The lubricant shelf is ranked in the best mineral oil enemas.

What it is. The Fleet Enema for Children is a 2.25 fl oz sodium phosphates enema, half the adult volume, with a smaller tip. The Drug Facts label lists relief of occasional constipation, states 1 to 5 minutes, and directs by age: children 5 to 11 years, 1 bottle; children 2 to under 5 years, a reduced amount printed on the label; children under 2, do not use. Do not use more than once in 24 hours.

Stop and ask a doctor for rectal bleeding or no bowel movement after use. If the pediatrician has not specifically said enema, the pediatric glycerin products are the less involved option; the best enemas for kids and Pedia-Lax vs Fleet Children's Enema cover the decision.

The generic. The Quality Choice Sodium Phosphates Rectal Solution Enema is a store-brand saline enema, latex free per the title, 2 bottles to the pack. The title does not state the volume; the Drug Facts panel does. At $7.99 (verified via the Amazon Creators API on September 5, 2026) each bottle is about $4.00 ($7.99 divided by 2), against about $1.42 for Fleet's 2 count.

Stop and ask a doctor for rectal bleeding or no bowel movement after use. Prices move; if this listing drops below Fleet's, the math and the ranking change with it.

The suppository alternative. Fleet Glycerin Suppositories, 50 count are the adult reference glycerin: 2 g per suppository, relief of occasional constipation, a bowel movement generally in 15 minutes to 1 hour, adults and children 6 and over. At $4.29 (verified via the Amazon Creators API on September 5, 2026) for 50, about 9 cents a dose ($4.29 divided by 50). No sodium phosphates, no age 55 line, no once-in-24-hours line.

Same laxative stop lines: rectal bleeding or no bowel movement after use means stop and ask a doctor; not more than 1 week without a doctor. The full write-up is our Fleet Glycerin Suppositories review.
