Oxcarbazepine Extended-Release Side Effects

Common Side Effects

Oxcarbazepine extended-release has been studied extensively in clinical trials. In these studies, the side effects that occurred in a group of people taking oxcarbazepine extended-release were carefully documented and compared to the side effects that occurred in a similar group of people taking a placebo (a "sugar pill" with no active ingredients). As a result, it was possible to see what side effects occurred, how often they appeared, and how they compared to the placebo.
 
In these studies, the most common oxcarbazepine extended-release side effects included:
 
  • Dizziness -- in up to 41 percent of people
  • Headache -- up to 15 percent
  • Vomiting -- up to 15 percent
  • Drowsiness -- up to 14 percent
  • Double vision -- up to 13 percent
  • Balance problems -- up to 7 percent
  • Loss of strength and energy -- up to 7 percent
  • Fatigue -- up to 6 percent
  • Tremor -- up to 5 percent.
 
Other common side effects, occurring in 2 percent to 4 percent of people, included:
 
  • Blurred vision
  • Uncontrollable eye movements (nystagmus)
  • Loss of muscle coordination
  • Upper abdominal (stomach) pain
  • Heartburn or indigestion
  • Inflammation of the lining of the stomach
  • Vision impairment
  • Problems moving or walking
  • Symptoms of the common cold, such as a runny nose, nasal congestion, or sneezing
  • General intolerance to taking the medication.
 

Final Thoughts

You may experience some or none of the side effects listed in this article. Unfortunately, there is no way for your healthcare provider to know beforehand if you will have problems with a medicine that you have never tried.
 
Therefore, make sure to let your healthcare provider know if you develop any side effects while taking oxcarbazepine extended-release or if something "just does not seem right." While it may not be related to the medication, your healthcare provider will be able to diagnose and treat the problem.
