CONSIDER THE FOLLOWING HISTORY OF A SLEEP CENTER PATIENT
A 34-year-old man comes to the sleep center with a complaint of daytime sleepiness. He takes clonazepam (Klonopin) as needed during the day to control panic attacks. He has difficulty falling asleep, and his primary care physician has prescribed quazepam (Doral) at bedtime. Other medical conditions include high blood pressure, for which he takes lisinopril (Zestril); allergies to pollen and tree mold treated with diphenhydramine (Benadryl); and high cholesterol treated with simvastatin (Zocor). His primary care doctor has sent him to the sleep center for possible treatment with modafinil (Provigil). After reviewing the patient’s medical history and medication list, you decide to contact the primary care doctor to discuss replacement of some the medications because they may be causing daytime sleepiness.
Which of the medications listed above are associated with daytime sedation?
What alternatives might be considered for the medications causing sedation?
