Glycerine Enema Prescription for a 5-Year-Old with Constipation
Dosing and Administration
- The American Academy of Pediatrics recommends prescribing a single pediatric glycerin suppository (1-1.5 grams) inserted rectally as needed, rather than a glycerin enema, as this is the appropriate formulation and safer route for this age group 1
- Glycerin suppositories work through local rectal irritation and by drawing water into the rectum, which softens stool and facilitates evacuation 1
- The suppository should be retained for 15-30 minutes if possible to maximize effectiveness 2
Critical Pre-Treatment Assessment
- Before prescribing any rectal intervention, a digital rectal examination should be performed to identify fecal impaction versus simple constipation, and rule out intestinal obstruction through physical examination 3, 4, 1
- Ensure the child does not have neutropenia, thrombocytopenia, recent colorectal surgery, anal trauma, or severe colitis 2, 3
- Check for undiagnosed abdominal pain, which is an absolute contraindication 2, 3
When Glycerin Suppositories Are Indicated
- Glycerin suppositories are appropriate when constipation has persisted for several days despite initial conservative measures 1
- The rectum is full on digital rectal examination 2
Common Pitfalls to Avoid
- Do not prescribe adult-sized glycerin suppositories or enemas for a 5-year-old—use pediatric formulations only 2
- Do not give oral laxatives alone if there is fecal impaction—the physical mass must be mechanically disrupted first 3
- Avoid prescribing rectal interventions without first ruling out obstruction, as this can lead to perforation 2
