EGD + Colonoscopy Prep — Under 15 kg [Under 33 lb]
🔎 What Are These Procedures?
Your child is scheduled for two procedures done back-to-back while asleep under anesthesia:
- EGD (upper endoscopy) — a thin camera is passed through the mouth to look at the esophagus, stomach, and the first part of the small intestine. Small biopsies are usually taken.
- Colonoscopy — the same kind of camera is passed through the bottom to look at the large intestine. Biopsies are usually taken here too.
Both procedures together take about 30–60 minutes. Your child will not feel anything.
📖 About the Bowel Prep
The colon must be clean for the doctor to see clearly during the colonoscopy. The medicines below clean the colon (empty it) over the day before. The EGD itself does not need bowel prep — only the fasting times.
✅ Medications and Supplies needed
- MiraLAX® (polyethylene glycol 3350) — only a small amount needed; see dose table below.
⚠️ NOT MiraLAX chewables - Pedialyte® or clear apple juice (for mixing the MiraLAX).
- Protective ointment (A&D, Desitin®, or Vaseline®) for the diaper area.
Prepare a list of medications.
Stop iron, anti-diarrhea medicine 7 days before.

⚖️ MiraLAX Pre-Cleanout — One Dose Per Day, 3 and 2 Days Before the Procedure
Normal diet on these days. Give one dose per day:

|---|---|---|
| Under 5 kg (under 11 lb) | ¼ capful (about 4 g) | Mix into 2–4 oz of Pedialyte or clear apple juice |
| 5–9 kg (11–20 lb) | ½ capful (about 8.5 g) | Mix into 4–6 oz of Pedialyte or clear apple juice |
| 10–15 kg (22–33 lb) | 1 capful (about 17 g) | Mix into 6–8 oz of Pedialyte or clear apple juice |

⚠️ When to Call the Doctor
- Your child won't drink, or has dehydration signs: no tears, dry mouth, or no wet diapers for 6+ hours.
- Vomiting that prevents your child from keeping liquids down.
- Fever, bloody stools, or severe belly pain.
- You are unsure whether the prep is working.
- You have questions about your child's medications.
Call (317) 338-9450 with any of the concerns above.
💡 Tips for Success
- Offer clear liquids frequently in small amounts — a syringe, sippy cup, or bottle may help.
- Popsicles and gelatin help keep your child hydrated. Avoid red and purple — they can look like blood.
- Expect frequent watery stools — this means the prep is working.
- Keep the diaper area well protected with ointment to prevent irritation.
