Some important things with Chloral Hydrate in liquid form...

The dose will be prescribed depending on your weight.
and
That dose will also depend on the strength of the actual solution. (although there is probably a standard)
and
The dose is also dependent on how many times a day you take it... meaning, if you take more than one dose, the dose amount might be lower but spread across the 24 hrs.

A teaspoon here is 5 mls.. In some places a teaspoon is a different measurement. If you know or find out the measurement of a teaspoon where you live, it's a better idea to buy a medicine glass and use that. Using teaspoons when taking those types of medicines is a little *iffy* for want of a better word. You really need to take an exact dose.

Chloral Hydrate was removed from market here too some years ago because of concerns with abuse, but I think they rescheduled it and it's used once again but not all that often here. It's seen more in Pediatrics for certain conditions and certain procedures. I've also often seen it mentioned on Child Neurology Forums actually, but recall quite varying results, but that was in children.

It also shouldn't be taken if you're already taking anticoagulants.
I found a site somewhere yesterday where it suggested that if it affects the throat or mouth mucosa then to take food after drinking it with the glass of juice or water. Another site said to take milk after it. I raced offline in a hurry and didn't save those 2 references, but can find them later if you want.

"If using chloral hydrate solution, measure your dose using a medication-measuring spoon or device. Do not use a household spoon because you may not get the correct dose. Mix your dose with a full glass of water or other liquid (e.g., fruit juice, ginger ale) before taking it.
Dosage is based on your medical condition, and response to treatment. In children, the dosage is also based on weight."

I found some info. at Mayo site... it's pretty much the same as the info. on the site mrsd has given you I think.
