Important Precautions

• Always inform your health-care practitioner about any other medical conditions you suffer from, especially heart, kidney, or liver disease, diabetes, an elevated potassium level, a blood cell disorder, lupus, or scleroderma.
• Lisinopril can affect your kidneys, especially if you have congestive heart failure. If you already have kidney disease, your dosage should be lower than usual.
• Before having any type of surgery or dental procedure, tell your surgeon or dentist that you are taking lisinopril.
• When you first start taking this drug or when the dosage is increased, you may experience dizziness or faintness when you rise quickly from a sitting or reclining position (postural hypotension). Try to get up slowly, and consult your health-care practitioner if the problem continues.
• Treatment of high blood pressure also entails certain lifestyle changes, such as weight control, smoking cessation, and close attention to diet.
• Be extremely careful when you exercise in hot weather. Heavy sweating can lead to dizziness, lightheadedness, fainting, vomiting, dehydration, and low blood pressure.
• Do not take this drug if you have ever experienced an allergic reaction to it or to other ACE inhibitors. If you have an allergic reaction such as swelling of the face and mouth and a sudden problem with breathing, seek immediate medical attention.
