Flexeril Lethargy Reviews

My mother, 87, was given Flexeril for a tight shoulder muscle. After 7 pills is having hallucinations. Mentally sharp otherwise. Last pill was on 12/29/2009. How long can we expect these? She is an invalid.

anxiety, anger, and exhaustion
Mon, 18 Apr 2011
I was taking Flexeril after I was diagnosed with a rib contusion following heavy lifting. I am taking Lexapro, Adderall and Trazadone already for A.D.D. depression and sleep deprivation. The Flexeril made me extremely tired, irritable, so much so that after a 24 hour period, I was nearly suicidal, possibly homicidal. I threw the medication away after reoccuring this feeling several times.
