Ativan 2 mg can be used as a single medication to treat seizures or in combination with other antidepressants for the effective treatment of panic disorder. You may consult your physician carefully to learn more about using Ativan with other medications. Ativan works by lessening the severity of epileptic seizures and panic attacks, decreasing their frequency over time. Ativan's anticonvulsant and relaxing properties can be attributed to the fact that it suppresses the central nervous system and increases the activity of GABA receptors.
