Side Effects of Tolterodine (Cont.)

Possible Side Effects of Tolterodine

Tolterodine has been studied thoroughly in clinical trials. In these studies, the side effects that occur in a group of people taking the drug are documented and are then compared to side effects that occur in another group of people not taking the medicine. This way, it is possible to see what side effects occur, how often they appear, and how they compare to the group not taking the medicine.
 
In these studies, the most common side effects of tolterodine included:
 
  • Dry mouth -- in up to 35 percent of people (see Detrol and Dry Mouth)
  • Headaches -- up to 7 percent
  • Constipation -- up to 7 percent
  • Dizziness or a spinning sensation (vertigo) -- up to 5 percent
  • Abdominal pain (stomach pain) -- up to 5 percent.
     
Other common tolterodine side effects, occurring in 1 to 4 percent of people, included:
 
  • Chest pain
  • Fatigue
  • Flu-like symptoms (such as fever, chills, or body aches)
  • Diarrhea
  • Indigestion or heartburn
  • Painful urination
  • Dry skin
  • Joint pain
  • Drowsiness
  • Weight gain (see Detrol and Weight Gain)
  • Infection

  • Problems focusing the eyes.
     

Final Thoughts on Side Effects of Tolterodine

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