Ativan, the brand name for lorazepam, is a prescription medication used to treat anxiety disorders, insomnia, and seizures. It belongs to a class of drugs called benzodiazepines, which work by enhancing the effects of a neurotransmitter called gamma-aminobutyric acid (GABA). This allows Ativan to calm down the overactivity in the brain, hence providing relief from physical and psychological symptoms of anxiety. Ativan is a powerful drug, and it is only available by prescription. It is important to note that it is not intended for long-term use, as prolonged use can lead to dependence and addiction. As a result, it is recommended for short-term use, typically no more than four weeks.   While Ativan is an effective medication for treating anxiety and other conditions for which it is prescribed, it can also be dangerous if not taken appropriately. The drug can cause drowsiness, dizziness, confusion, and impaired coordination. Therefore, it is essential to take the drug only as prescribed by the doctor, and not take it in combination with alcohol or other drugs known to cause drowsiness.
