Enalapril Side Effects
Some people experience side effects with enalapril, such as changes in blood pressure, body weakness, or dizziness. Although most side effects are mild, it is always wise to notify your healthcare provider if any problems develop while taking enalapril. Along with the more common side effects, there are some serious (but rare) problems that can occur, such as an allergic reaction, unexplained swelling, and infections.
Side Effects of Enalapril: An Introduction
As with any medicine, side effects are possible with enalapril (sold as Vasotec® and generic Enalapril Maleate), but not everyone who takes the medicine will experience problems. In fact, most people tolerate it well. If people do develop enalapril 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 enalapril because of side effects.
This medication 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 Enalapril Side Effects in People With High Blood Pressure
Enalapril 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 enalapril seen in people with high blood pressure include:
- Headache -- in up to 5.2 percent of people
- Fatigue -- up to 3 percent
- Dizziness -- up to 4.3 percent.
