Central nervous system side effects usually occur only in the first few days of treatment, and then get better. The side effects may include drowsiness, confusion, weakness, dizziness, and feeling faint. Benzodiazepines can cause serious changes in behavior and thinking, such as bizarre or uninhibited behavior, agitation, hallucinations, paranoia, panic, delirium, and sleepwalking. There may be no memory of these afterwards. Benzodiazepines can make it dangerous for a person to drive or to use machinery the next day.
