... much needed sleep, which has been lacking. Sleep at night has become more reasonable; however, daytime sleepiness is now interfering with normal daytime activities. Prior to the use of the mirtazapine at night, this patient had made use of 5 mg of lexapro, each a.m., in the treatment of ADHD and depression. This medication was ceased 3 weeks prior to the beginning of the mirtazapine. Now that daytime sleeipiness is creating a problem, the patient is wondering whether the lexapro, at 5 mg each morning, might be of assist in maintaining wakefulness, during the day. The patient has read that the use of these 2 drugs simultaneously might pose some risk. Some counsel of experience, in the use of these drugs, lexapro & mirtazapine, simultaneously, will be greatly appreciated! Thank You!
