Which of the following statements about sedatives and hypnotics is NOT true?

The statement indicating that sedatives and hypnotics are commonly prescribed for long-term use in high dosages is not true. In clinical practice, sedatives and hypnotics are typically recommended for short-term management of conditions such as anxiety or sleep disorders, primarily due to the risks associated with long-term use, including tolerance, dependence, and withdrawal symptoms.

Medical guidelines usually suggest that these medications be used at the lowest effective dose for the shortest duration necessary to manage symptoms. This cautious approach is essential to minimize the potential for adverse effects and psychological dependence. In contrast, the other statements are aligned with pharmacological principles and common clinical practices. Sedatives and hypnotics can indeed cause dependence when used improperly, and they play a role in managing anxiety and sleep disorders, justifying their use within controlled and time-limited contexts.
