Ativan is a prescription medication that belongs to a class of drugs known as benzodiazepines. It is primarily used to treat anxiety disorders, insomnia, and seizures.

Ativan works by increasing the activity of a neurotransmitter called gamma-aminobutyric acid (GABA) in the brain. GABA helps to calm the brain and nervous system, which can reduce anxiety, promote sleep, and prevent seizures.

Common side effects of Ativan may include drowsiness, dizziness, weakness, and confusion. More serious side effects can include slowed breathing, severe allergic reactions, and dependence or addiction if taken in high doses or for a prolonged period.

It is important to take Ativan only as directed by a healthcare professional and to use caution when driving or operating machinery, as it can cause drowsiness and impair thinking and reaction times. Ativan should never be shared with others, as it can be dangerous or fatal if misused or abused.
