from eMedTV.comCommon Side Effects of Benazepril
Benazepril has been studied extensively in clinical trials, with thousands of people worldwide having been evaluated. In these studies, side effects are always documented and compared to side effects that occur in a similar 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.
Based on these studies, the most common benazepril side effects include:
- Headache -- up to 6 percent
- Dizziness -- up to 3.6 percent
- Fatigue -- up to 2.4 percent.
Other side effects of benazepril occurring in more than 1 percent of people include, but are not limited to:
- Excessive tiredness
- Nausea
- Cough (see Lotensin Cough).
