Ativan, of the drug class benzodiazepine, is a strong sedative that is often prescribed for anxiety disorders, some seizure disorders, and it is occasionally used to help calm aggressive or violent tendencies in some individuals. It is relatively fast acting and is highly addictive. Because of this, it is intended to be used short-term and is not recommended for extended use due to its habit forming nature. It blocks the neurotransmitters of the brain from hyperactive mental activities. For example, patients can take the drug orally or inject via IV drip. As a result, benzodiazepine users will feel the effect of Ativan within two hours after intake. Additionally, it will take an average of 10 to 20 hours before the drug leaves the system. It should only be used under the direct supervision of a healthcare professional.
