Congestive Heart Failure Home > Vasotec Side Effects

Although most people tolerate the medication well, side effects may occur with Vasotec. Common problems reported with the medication include headaches, dizziness, fatigue, and low blood pressure. Report any serious side effects to your healthcare provider immediately, such as wheezing, fainting spells, or unexplained swelling of the head or neck.

An Overview of Vasotec Side Effects

As with any medicine, there are possible side effects associated with Vasotec® (enalapril); however, not everyone who takes Vasotec will experience side effects. In fact, most people tolerate it 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.
Serious side effects can occur but are less common. About 3 percent of people with high blood pressure (and about 6 percent of people with congestive heart failure) stop taking Vasotec because of side effects.
Vasotec has been studied in a number of groups of people with different conditions. Because the groups were so different, the side effects are broken down by group. These groups include people with:

Common Side Effects of Vasotec in People With High Blood Pressure

Vasotec has been studied extensively in clinical trials. In these trials, thousands of people worldwide have 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 Vasotec side effects seen in people with high blood pressure include:
  • Headache -- reported in up to 5.2 percent of people
  • Dizziness -- reported in up to 4.3 percent of people
  • Fatigue -- reported in up to 3 percent of people.
