Here is a thorough answer based on the evidence:
Triclofos in an 11-Month-Old Infant
Yes, triclofos can be given to an 11-month-old infant, but only under medical supervision, for an appropriate indication, and at a correct weight-based dose. Here is what you need to know:
What is Triclofos?
Triclofos sodium (brand name: Pedicloryl syrup, 500 mg/5 mL) is a chloral hydrate derivative used as an oral sedative in children. It is considered safer than chloral hydrate because it causes less gastric irritation, is more palatable, and has an available liquid formulation. It is metabolized to trichloroethanol, which produces sedation.
Is it Safe for Infants?
Yes, for infants from 6 months of age onwards. Multiple studies confirm safety in this age group:
- A large RCT published in Archives of Disease in Childhood (2025, PMID 39580155) enrolled children aged 6 months to 12 years and found triclofos (50 mg/kg) was safe and effective for sleep EEG, with no serious adverse events in infants.
- Jackson et al. studied triclofos in children under 2 years and found it safe up to 100 mg/kg with no arterial desaturation.
- Jain et al. studied children aged 6 months to 5 years with no serious adverse effects in 160 patients.
At 11 months, your baby falls squarely within the studied and approved age range.
Dosing
| Purpose | Dose | Maximum |
|---|
| Procedural sedation / sleep EEG | 50 mg/kg oral, single dose | Usually 1 g |
| Ophthalmic examination | 75-80 mg/kg oral | Typically not >100 mg/kg |
| If no sedation after 60 min, may repeat | 50 mg/kg additional dose | As per treating physician |
Example: An 11-month-old weighing ~9 kg would receive approximately 450 mg (4.5 mL of Pedicloryl syrup) at the 50 mg/kg dose.
Common Uses in Infants
- Sleep EEG / brain wave test
- MRI (to keep the baby still)
- Ophthalmic examination (eye check)
- Minor procedures requiring minimal movement
Side Effects to Watch For
- Drowsiness (expected and intended)
- Nausea or vomiting (mild gastric irritation)
- Paradoxical excitation (uncommon - child becomes more agitated)
- Respiratory depression at high doses (rare at standard doses)
Important Cautions
- Give only under medical supervision - the child should be monitored (oxygen saturation, breathing) during and after sedation.
- Do not give at home without a doctor's instruction - this is a prescription sedative.
- Avoid if the baby has: liver or kidney disease, respiratory problems, or known hypersensitivity to chloral hydrate derivatives.
- Do not combine with other CNS depressants without physician guidance.
- Onset is typically 20-45 minutes; keep the baby in a quiet, calm environment after administration.
- Keep the baby fasting appropriately before the procedure (as advised by the doctor).
Bottom Line
Triclofos at 50 mg/kg orally is well-established, safe, and effective for sedation in infants aged 6 months and above, including an 11-month-old. It should always be administered under medical supervision for a specific clinical purpose (EEG, MRI, ophthalmic exam, etc.), not given at home for general fussiness or sleep.
If a doctor has prescribed it for your baby for a procedure, it is appropriate. If you are considering giving it without a prescription, please consult your pediatrician first.
