Understanding Clinical Trials
Before medicines are approved, they must go through several clinical studies. In these studies, thousands of people are given a particular medicine and are then compared to a group of people not given the medicine. During these studies, the side effects are always documented. As a result, it is possible to see what side effects occur, how often they appear, and how they compare to the group not taking the medicine. It is then possible to get a better idea of what side effects may be related to the medicine or to things besides the medicine, such as the condition itself.
It does appear that insomnia is a possible side effect of Haldol. In previous clinical studies, insomnia occurred more often in people taking Haldol than in those who were not taking the medication.
