Do doctors ever prescribe glutethimide for insomnia? If so, does it have to be dispensed at a compounding pharm? I ask because I m too tolerant on z-drugs and antihistamines, benzos usually work, but I ve gotten into trouble in the past by staying on them for several years. My insomnia is super-stubborn, and I ve had it for most of my 45 years. My ideal management strategy; if possible, would be to take a different class of hypnotic pharm 2x/week, so that I wouldn t be physically dependent on any one particular med.
