🔎 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. The colonoscopy needs the bowel-prep medicines below; the EGD only needs the fasting times. Follow both.

📖 About the Bowel Prep

The colon must be clean for the doctor to see clearly during the colonoscopy. The medicines below empty it over the day before. The EGD itself does not need bowel prep — only the fasting times.

For infants and children under 15 kg only

This page describes the oral MiraLAX prep dosed by weight. If your child cannot tolerate oral MiraLAX, ask the office about the clear-liquids + saline-enema option.

✅ Plan Ahead — pick up from the pharmacy

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.

Medications: please prepare a list of the medicines your child is taking and ask which ones may need to be stopped. Stop iron supplements and anti-diarrhea medicines 7 days before.

⚖️ MiraLAX Dose by Weight

Your Child's Weight	MiraLAX Dose	How to Give
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)	¾ capful (about 13 g)	Mix into 6–8 oz of Pedialyte or clear apple juice

If your child has trouble drinking it all at once, offer it in small sips over 1–2 hours.

📅 3 Days and 2 Days Before the Procedure

Continue your child's normal diet.
Give one MiraLAX dose per day, mixed into juice or Pedialyte (see dose table above).

⏱ Fasting Rules — Day of Procedure

These times are counted backward from your child's scheduled procedure time. The fasting rules apply to both the EGD and the colonoscopy.

What	When to Stop
All solid and low-residue foods	6:00 PM the day before
Formula	10:00 PM the day before
Breast milk	2:00 AM the day of procedure
Clear liquids (Pedialyte, water, clear juice)	3 hours before procedure time

⚠️ After the clear-liquid cutoff, no food or drink. This keeps your child safe during anesthesia.

⚠️ 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.
