Final answer:
Lunesta and Ambien are classified as Schedule IV, not Schedule III drugs, and while they are used to treat insomnia, there is concern about their overtreatment and side effects.
Step-by-step explanation:
Lunesta and Ambien are not classified as Schedule III drugs; they are categorized as Schedule IV drugs under the Controlled Substances Act. This classification is due to their lower potential for abuse and dependence compared to Schedule III drugs. While these sleep aids are marketed to help with insomnia, concerns have been raised about their overtreatment and potential side effects. Therapists often recommend changes in sleep hygiene, such as spending less waking time in bed, to combat insomnia without medication. It's also noted that cognitive behavioral therapy has been found to be the most effective sleep intervention, further emphasizing the need to scrutinize the frequent use of medications like Lunesta and Ambien.
