Ativan^® (lorazepam) is a drug that is approved to treat anxiety. The drug is thought to work in the brain by enhancing the effects of gamma-aminobutyric acid (GABA) -- a brain chemical that is naturally calming. Ativan comes in tablet, oral liquid, and injectable forms. A few common side effects of this drug include dizziness, weakness, and unsteadiness.

 

For the medication to work properly, it must be taken as prescribed. Ativan may cause serious problems if you take it at higher dosages or for a longer period of time than your healthcare provider recommends. If you happen to overdose on Ativan, seek immediate medical attention. Some possible symptoms of an Ativan overdose include sedation, confusion, speech problems, low blood pressure (hypotension), and even loss of life.
