You might feel dizzy when you start taking enalapril (Vasotec), and when your provider raises your dose. This should get better over time as you continue taking the medication and your body gets used to your new blood pressure. Stand up slowly and carefully from a sitting or lying down position to avoid falling.
Let your provider know if you feel faint or pass out after taking enalapril (Vasotec). They might need to switch you to a different blood pressure medication.
Make sure to drink enough water to stay hydrated while you're taking enalapril (Vasotec), especially on hot days or after exercising. Your blood pressure might drop too much if you don't have enough fluids in your body. This can worsen dizziness and raise your risk of falls.
Enalapril (Vasotec) can interact with a lot of other medications. For example, you should avoid taking non-steroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen (Advil), while taking enalapril (Vasotec) unless your provider says it's okay. This is because taking NSAIDs and enalapril (Vasotec) together might cause kidney problems. Make sure to tell your provider about all the medications you're taking before starting enalapril (Vasotec).
Make sure to have a healthy diet, including a low-salt diet, while taking enalapril (Vasotec) to help lower your blood pressure. Depending on your risk factors and other medical problems, it's possible you might be able to stop taking enalapril (Vasotec) if your blood pressure is well-controlled through healthy eating and exercise.
Don't take enalapril (Vasotec) if you're pregnant. If you're pregnant or thinking of getting pregnant, contact your provider right away. Your provider might prescribe you a different medication that's safer during pregnancy. Or, they might recommend ways to help control your blood pressure with lifestyle changes instead.

Only use an oral syringe or medication dose cup from the pharmacy to measure out your dose. Never use household spoons because they aren't accurate, which can make you take the wrong dose.

Enalapril (Vasotec) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.

Risk factors: Black people | Having angioedema in the past
People who take medications that contain an ACE inhibitor, like enalapril (Vasotec), can experience a rare, but serious side effect called angioedema. This involves swelling in different parts of the body, including the face, throat, and tongue. Swelling of the tongue or throat area can be potentially life-threatening, since it can make it difficult to breathe. Angioedema can happen at any time during treatment. You're more likely to experience angioedema if you're Black, an older adult, or female. Get medical attention immediately if you experience swelling in any of the areas mentioned above, stomach pain, or difficulty breathing. You'll have to stop taking enalapril (Vasotec) if this happens.
Risk factors: Not enough fluid in your body | Having diarrhea or vomiting for a long time | Low salt levels in your body | Taking higher doses of diuretic medications
Sometimes, taking enalapril (Vasotec) can cause your blood pressure to drop too much. This can cause you to feel dizzy, tired, or lightheaded. This side effect is more common when you first start enalapril (Vasotec) or when the dose is raised. Make sure to stay well-hydrated. If your blood pressure drops too much and you feel dizzy, make sure to sit down slowly while holding onto something and let your provider know. If you fall and hit your head, get medical help right away. If you feel dizzy, lightheaded, faint, tired, or confused while taking enalapril (Vasotec), contact your provider right away.
Risk factors: Severe heart failure | Kidney problems | Not enough fluid in your body | Taking other medications that can cause kidney damage | History of narrow heart valves (aortic stenosis)
Enalapril (Vasotec) is usually good for the kidneys. But in some cases it can make kidney problems worse. The risk is higher for people who have certain types of kidney problems, such as renal artery stenosis or very severe heart failure. Your provider might order lab tests every so often to make sure your kidneys are healthy and working properly. Your provider will check your kidneys before starting enalapril (Vasotec) and regularly as needed. Let your provider know if you're urinating less often than usual, as this could be a sign that your kidneys aren't working as well.
Risk factors: Diabetes | Kidney problems | Taking other medications that also raise potassium
Enalapril (Vasotec) can raise the amount of potassium in your body, which can be dangerous. Your risk of developing high potassium is greater if you have diabetes, kidney problems, or are taking other medications that also raise potassium levels. For this reason, make sure your provider knows your full medical history and what medications you're taking before starting enalapril (Vasotec). If you experience signs of high potassium levels, such as nausea, muscle weakness, or abnormal heartbeat, tell your healthcare provider right away.
Risk factors: History of liver problems | Drinking large amounts of alcohol
In some rare cases, people who took ACE inhibitors like enalapril (Vasotec) have developed a blocked bile duct. This condition can lead to liver problems or liver failure. Your provider might order blood tests to check your liver health from time to time. If you notice symptoms of liver problems, such as tiredness, stomach pain, or yellowing of your skin, let your provider know right away.
