• Blood pressure medications work by different mechanisms to decrease blood pressure. The ultimate decrease in blood pressure also means a decrease in the amount of work the heart is doing, which can lead to a feeling of fatigue. Sometimes, the drug works not only on the heart, but also on the central nervous system.
  
  
  • Beta-blockers
    
    
  • Calcium channel blockers
    
    
  • Diuretics
    
    
  • ACE inhibitors
  
  
• Heart medications work in different ways to regulate the heartbeat. Fatigue can be related to the effects the medication has on the heart or to the effects that spill over to other areas of the body.
  
  
  • Digoxin (Lanoxin)
    
    
  • Amiodarone (Cordarone, Pacerone)
    
    
  • Procainamide (Promine, Rhythmin)
  
  
• Psychological medications used to help depression and anxiety work by increasing neurotransmitters in the brain that have a calming effect on the body, thus stimulating fatigue.
  
  
  • Antidepressants
    
    
  • Antipsychotics
    
    
  • Antianxiety medications (such as diazepam [Valium] or zolpidem[Ambien])
  
  
• Narcotics: Many pain medications are opiate derived. Drowsiness can be caused by opiates.

  • Oxycodone and acetaminophen (Percocet)
    
    
  • Propoxyphene and acetaminophen (Darvocet)
  
  
• Muscle relaxants work to decrease the contraction of muscles. This relaxation can lead to total body relaxation, which may cause you to feel fatigued.
  
  
  • Cyclobenzaprine (Flexeril)
    
    
  • Carisoprodol (Soma)
