Common Quinapril Side Effects
Quinapril 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 side effects of quinapril seen in people with
high blood pressure include:
- Headache -- up to 5.6 percent
- Dizziness -- up to 3.9 percent
- Fatigue -- up to 2.6 percent
- Cough -- up to 2 percent (see Accupril Cough).
- Dizziness -- up to 7.7 percent
- Cough -- up to 4.3 percent
- Extremely low blood pressure -- up to 2.9 percent
- Fatigue -- up to 2.6 percent
- Chest pain -- up to 2.4 percent.
Other quinapril side effects (occurring in more than 1 percent of people with high blood pressure or
heart failure) include, but are not limited to:
- Nausea
- Vomiting
- Stomach pain
- Shortness of breath
- Unexplained rash
- Diarrhea.
Rare Quinapril Side Effects
There are other possible quinapril side effects that can occur. These rare side effects occur in less than 1 percent of people. Given how uncommonly they occur, it can be difficult to tell whether these side effects are caused by the medication or something else.
Some of these possible rare side effects of quinapril include, but are not limited to:
