Triazolam (Halcion) Triazolam is used routinely by many dentist for oral conscious sedation. The medication is very safe when used appropriately. One of the best "side-effect" i've noticed with my patients is they have amnesia so they don't remember the procedure. I posit the patients don't mind this too much. Make sure you ask your dentist if you have questions about medications and why they are using them.
