Chloral Hydrate Syrup: Uses, Benefits, Side Effects, History & Safety Guide

What Is Chloral Hydrate Syrup?

Chloral Hydrate Syrup is a sedative and hypnotic medication that has historically been used to induce sleep and calm patients before medical procedures. It acts on the central nervous system (CNS) to produce a calming and sleep-inducing effect.

Due to safety concerns and the availability of newer, safer medicines, its use today is very limited and strictly controlled, especially in children.

📜 History: From First Discovery to Present Day

Chloral Hydrate has one of the oldest histories in modern medicine.

  • 1832: Chloral hydrate was first synthesized by chemist Justus von Liebig

  • 1869: Discovered to have sedative and hypnotic properties

  • Late 19th – Early 20th century: Widely used as a sleep medicine and sedative

  • Mid-1900s: Commonly prescribed for insomnia, anxiety, and pediatric sedation

  • Late 20th century: Decline in use due to:

    • Risk of dependence

    • Cardiac and respiratory side effects

    • Availability of safer alternatives (benzodiazepines, melatonin, etc.)

Today, chloral hydrate is rarely prescribed, mainly used:

  • In specialist medical settings

  • For procedural sedation

  • Under strict medical supervision

Chloral Hydrate depresses activity in the central nervous system, slowing brain signals that cause wakefulness. This results in:

  • Sedation

  • Drowsiness

  • Induced sleep

It does not treat the cause of insomnia—only the symptom.
