Side Effects of Doxazosin XL

Common Side Effects

Doxazosin XL has been studied thoroughly in clinical trials. In these studies, the side effects that occurred in a group of people taking the drug were documented and compared to the side effects that occurred in another group of people not taking the medicine. As a result, it was possible to see what side effects occurred, how often they appeared, and how they compared to the group not taking the medicine.
In these studies, the most common side effects of doxazosin XL included:
  • Headaches -- in up to 6 percent of men
  • Dizziness -- up to 5.3 percent
  • Respiratory tract infections (such as the common cold) -- up to 4.8 percent
  • General weakness or lack of strength -- up to 3.9 percent
  • Back pain -- up to 2.9 percent.
Other common side effects, occurring in 1 to 2 percent of men, included:
  • Abdominal pain (stomach pain)
  • Low blood pressure (hypotension)
  • Low blood pressure when rising suddenly (postural hypotension)
  • Indigestion or heartburn
  • Nausea
  • Muscle pain
  • Drowsiness
  • A spinning sensation (vertigo)
  • Shortness of breath
  • A urinary tract infection (such as a bladder infection).
It should also be noted that less than 1 percent of men reported problems with impotence (also known as erectile dysfunction, or ED) or a decreased sex drive with this medication.

Final Thoughts

You may experience some or none of the doxazosin XL 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 doxazosin XL 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.
