What effect can occur when sedative/hypnotics are used excessively?

The use of sedative/hypnotics, particularly when taken in excessive amounts, is closely associated with the development of dependency and withdrawal symptoms. Sedative/hypnotics are designed to depress the central nervous system, leading to decreased arousal and relaxation. When individuals use these medications beyond recommended dosages, their bodies can become reliant on the substances to function normally, resulting in physical and psychological dependency.

Once a dependence develops, suddenly reducing or stopping the medication can lead to withdrawal symptoms. These might include increased anxiety, agitation, sleep disturbances, and even physical symptoms such as tremors. This cycle of dependency and withdrawal underscores the importance of using sedative/hypnotics under strict medical supervision and adhering to prescribed guidelines to mitigate risks associated with their use.

In contrast, heightened alertness and anxiety, improved cognitive function, and increased motor skills are not effects associated with excessive use of sedative/hypnotics. In fact, such drugs typically lead to decreased alertness, impaired cognitive function, and reduced motor skills instead.
