Ativan (lorazepam) is a benzodiazepine used for the management of anxiety disorders, insomnia, panic attacks, and alcohol withdrawal. A generic formulation of Ativan is available. Common side effects of Ativan include drowsiness, dizziness, muscle weakness, headache, blurred vision, sleep problems (insomnia), loss of balance or coordination, forgetfulness, difficulty concentrating, nausea, vomiting, constipation, changes in appetite, or rash. Like all benzodiazepines, Ativan can cause physical dependence. Suddenly stopping therapy may be associated with agitation, insomnia, seizures, tremors, vomiting, and sweating.
The usual dose of Ativan for treating anxiety is 2-3 mg/day given in two or three divided doses. Insomnia is treated with 2-4 mg given at bedtime. Ativan and other benzodiazepines have been associated with fetal damage, including congenital malformations, when taken by pregnant women in their first trimester. Ativan is best avoided if at all possible in the first trimester and probably throughout pregnancy. It is not known if Ativan is secreted in breast milk.
