Flexeril Fatigue Causes and Reviews


Everyone feels tired now and then. Sometimes you may just want to stay in bed. But, after a good night's sleep, most people feel refreshed and ready to face a new day. If you continue to feel tired for weeks, it's time to see your doctor. He or she may be able to help you find out what's causing your Fatigue and recommend ways to relieve it.

Fatigue itself is not a disease. Medical problems, treatments, and personal habits can add to Fatigue. These include

  • Taking certain medicines, such as antidepressants, antihistamines, and medicines for nausea and pain
  • Having medical treatments, like chemotherapy and radiation
  • Recovering from major surgery
  • Anxiety, stress, or depression
  • Staying up too late
  • Drinking too much alcohol or too many caffeinated drinks
  • Pregnancy

One disorder that causes extreme Fatigue is chronic Fatigue syndrome (CFS). This Fatigue is not the kind of tired feeling that goes away after you rest. Instead, it lasts a long time and limits your ability to do ordinary daily activities.

Flexeril Fatigue Reviews

Sat, 09 Jan 2010
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.
