A sedative is a substance that induces sedation by reducing irritability or excitement. At higher doses it may result in slurred speech, staggering gait, poor judgment, and slow, uncertain reflexes. Doses of sedatives such as benzodiazepines when used as a hypnotic to induce sleep tend to be higher than those used to relieve anxiety where as only low doses are needed to provide calming sedative effects. Sedatives are used by Stargate Command and the Atlantis expedition, as well as the Destiny expedition, who have also used Squiggler venom as a sedative. (SGU: "Pain")
