Sedatives such as benzodiazepines are primarily used to treat anxiety disorders such as panic attacks, phobias, and obsessive-compulsive disorder. Benzodiazepines are highly effective in reducing anxiety and can also aid in helping individuals who suffer from sleep problems or seizures. However, they are very popular substances of abuse due to the feelings of detachment and relaxation that they produce. Unfortunately, when benzodiazepines like these are abused, individuals are at risk for experiencing excessive sleepiness, drowsiness, and respiratory depression. When an individual becomes physically and psychologically dependent on these prescription drugs and attempts to stop using suddenly, he or she can suffer from deadly withdrawal symptoms including seizures.
