Ativan is typically only meant to be used on a short-term basis, as taking it for long periods of time can lead to tolerance, dependence, and addiction. Some of the other risks associated with taking Ativan include drowsiness, impaired coordination, and slowed reaction times. If you take Ativan everyday, you may find that your body quickly becomes tolerant to the drug, requiring higher and higher doses to achieve the same effect. As a result, it is important to only take Ativan as prescribed by a doctor and to talk to a doctor if you think you may be addicted to the drug.
