An Introduction to Accupril Side Effects
As with any medicine, there are possible side effects with
Accupril® (
quinapril hydrochloride); but not everyone who takes Accupril will experience side effects. In fact, most people tolerate the medicine well. When people do develop side effects, in many cases they are minor, meaning they require no treatment or are easily treated by you or your healthcare provider.
(This article covers many, but not all, of the possible side effects with Accupril. Your healthcare provider can discuss a more complete list of side effects with you.)
Common Side Effects of Accupril
Accupril has been studied extensively in clinical trials, with thousands of people worldwide having been evaluated.
In these studies, the side effects that occurred in a group of people taking the drug were documented and then compared to the side effects that occurred in another group of people taking a placebo (a "sugar pill" that does not contain any active ingredients). 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.
Based on these studies, the most common side effects of Accupril seen in people with high
blood pressure include:
- Headache -- in up to 5.6 percent of people
- Dizziness -- up to 3.9 percent
- Fatigue -- up to 2.6 percent
- Cough -- up to 2 percent (see Accupril Cough).
In people with congestive
heart failure, the most common side effects include:
- Dizziness -- in up to 7.7 percent of people
- 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 Accupril 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.
