What should patients do regarding medications before a polysomnography study?

Patients should avoid certain medications as directed before a polysomnography study to ensure the most accurate evaluation of their sleep patterns and quality. Certain medications, particularly those that affect the central nervous system, such as sedatives, antidepressants, and other sleep aids, can significantly alter sleep architecture. These medications may suppress REM sleep or affect the overall quality and stages of sleep, leading to misleading results.

By following the specific directions provided by their healthcare provider regarding which medications to avoid, patients help the technologists obtain a clearer picture of their natural sleep patterns. This, in turn, assists in accurate diagnosis and effective treatment planning for sleep disorders.

Adhering strictly to medication guidelines ensures that the polysomnography study reflects the patient's baseline sleep state, which is vital for the validity of the results. Therefore, the recommendation to avoid certain medications is essential for obtaining objective and reliable data during the study.
