Ativan Side Effects

While most people tolerate Ativan well, side effects can still occur during treatment with the drug. Common side effects of Ativan can include dizziness, weakness, and unsteadiness. A few other possible side effects include nausea, constipation, and fatigue. Some Ativan side effects are more serious and require immediate medical attention; be sure to report side effects such as seizures or suicidal thoughts to your healthcare provider right away.

 

An Introduction to Ativan Side Effects

As with any medicine, side effects are possible with Ativan® (lorazepam); however, not everyone who takes the medication will experience side effects. In fact, most people tolerate it quite well. If side effects do occur, in most cases, they are minor and either require no treatment or are easily treated by you or your healthcare provider.

Common Side Effects of Ativan

Ativan has been studied thoroughly in clinical trials. In these studies, the side effects that occur in a group of people taking the drug are documented and are then compared to side effects that occur in another group of people not taking the medicine. This way, it is possible to see what side effects occur, how often they appear, and how they compare to the group not taking the medicine.
 
In these studies, the most common side effects of Ativan included:
 
  • A sleeping or calming effect (known medically as sedation) -- in up to 15.9 percent of people
  • Dizziness -- up to 6.9 percent
  • Weakness -- up to 4.2 percent
  • Unsteadiness -- up to 3.4 percent.
