Tramadol Side Effects

Common Tramadol Side Effects

Tramadol has been studied thoroughly in clinical trials. In these studies, one group of people received the real medication, while another group was given a different pain medication. As a result, it is possible to see what side effects occurred, how often they appeared, and how they compared to the other medication.
 
In these studies, the most common side effects of tramadol included:
 
  • Constipation -- in up to 46 percent of people
  • Nausea -- up to 40 percent
  • Dizziness or a spinning sensation (vertigo) -- up to 33 percent
  • Headaches -- up to 32 percent
  • Drowsiness -- up to 25 percent
  • Vomiting -- up to 17 percent
  • Nervousness, shakiness, agitation, or other "overstimulation" problems -- up to 14 percent.
     
Other common side effects (occurring in 1 to 13 percent of people) included but were not limited to:
 
  • Itching
  • Weakness
  • Sweating
  • Indigestion or heartburn
  • Dry mouth
