As with nearly all anesthetic drugs,<unk>  causes cardiovascular and respiratory depression resulting in hypotension, apnea, and airway obstruction. For these reasons, only suitably trained medical personnel should give<unk>  in an environment suitably equipped to deal with these effects. Side effects include headache, agitated emergence, prolonged somnolence, and nausea. Intravenous administration of<unk>  is followed instantly by an odor and/or taste sensation, sometimes described as being similar to rotting onions, or to garlic. The hangover from the side effects may last up to 36 hours. Although each molecule of<unk>  contains one sulfur atom, it is not a sulfonamide, and does not show the allergic reactions of sulfa/sulpha drugs.
