Pediatric Glycerin Suppository Dosing
A pediatric glycerin suppository contains either 1 gram or 250-500 mg of glycerin, depending on the specific formulation and age/weight of the child.
Standard Dosing by Weight/Age
Based on the available evidence, pediatric glycerin suppositories come in different strengths:
- 1 gram (1000 mg): Used in very low birthweight preterm neonates (1000-1500 g birthweight) 1
- 250 mg: Used for extremely premature infants (24-27 weeks gestation) 2
- 500 mg: Used for slightly older premature infants (28-31 weeks gestation), typically administered as two 250-mg suppositories 2
Clinical Context
The research evidence consistently shows these dosing ranges across multiple randomized controlled trials in neonatal populations. The 250 mg dose appears to be the smallest commercially available pediatric formulation, while 1 gram represents a standard dose for slightly larger infants 1, 2.
Important Caveats
- No standard "one-size" pediatric suppository exists - the dose varies based on patient size and clinical indication
- The evidence base primarily comes from neonatal intensive care settings, where these specific doses were studied
- For general pediatric use outside the NICU setting, 1 gram is commonly referenced as a standard pediatric dose 1
The most commonly encountered pediatric glycerin suppository in clinical practice contains 1 gram of glycerin, though smaller 250-500 mg formulations exist for premature or very small infants.
