Drug Information

Lisinopril is used to treat high blood pressure. Lowering high blood pressure helps prevent strokes, heart attacks, and kidney problems. It is also used to treat heart failure and to improve survival after a heart attack. Lisinopril belongs to a class of drugs known as ACE inhibitors. It works by relaxing blood vessels so blood can flow more easily.

Take this medication by mouth with or without food as directed by your doctor, usually once daily. If you are using the suspension form of this medication, shake the bottle well before each dose. Carefully measure the dose using a special measuring device/spoon. Do not use a household spoon because you may not get the correct dose. The dosage is based on your medical condition and response to treatment. For children, the dosage is also based on weight. To reduce your risk of side effects, your doctor may direct you to start this medication at a low dose and gradually increase your dose. Follow your doctor's instructions carefully.

Use this medication regularly to get the most benefit from it. To help you remember, take it at the same time each day. Keep taking this medication even if you feel well. Most people with high blood pressure do not feel sick. For the treatment of high blood pressure, it may take 2 to 4 weeks before you get the full benefit of this medication. For the treatment of heart failure, it may take weeks to months before you get the full benefit of this medication. Tell your doctor if your condition does not get better or if it worsens (for example, if your blood pressure readings remain high or increase).

Dizziness, lightheadedness, tiredness, or headache may occur as your body adjusts to the medication. A dry cough may also occur. Tell your doctor or pharmacist promptly if any of these effects last or get worse. To reduce the risk of dizziness and lightheadedness, get up slowly when rising from a sitting or lying position. Remember that this medication has been prescribed because your doctor has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects. Tell your doctor right away if you have any serious side effects, including fainting and symptoms of a high potassium blood level (such as muscle weakness and slow/irregular heartbeat). Although lisinopril may be used to prevent kidney problems or treat people who have kidney problems, it may also rarely cause serious kidney problems or worsen them. Your doctor will check your kidney function while you are taking lisinopril.

Tell your doctor right away if you have any signs of kidney problems, such as a change in the amount of urine. Lisinopril may rarely cause serious (possibly fatal) liver problems. Get medical help right away if you have any symptoms of liver damage, such as nausea/vomiting that doesn't stop, loss of appetite, stomach/abdominal pain, yellowing eyes/skin, or dark urine. A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, or trouble breathing. This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.

Call your doctor for medical advice about side effects. You may report side effects to the FDA at 1-800-FDA-1088 or at www.fda.gov/medwatch.

Drug interactions may change how your medications work or increase your risk for serious side effects. This document does not contain all possible drug interactions.

Some products that may interact with this drug are aliskiren, certain drugs that weaken the immune system/increase the risk of infection (such as everolimus, sirolimus), lithium, and drugs that may increase the level of potassium in the blood (such as ARBs including losartan/valsartan, birth control pills containing drospirenone), sacubitril. Some products have ingredients that could raise your blood pressure or worsen your heart failure.

Tell your pharmacist what products you are using, and ask how to use them safely (especially cough-and-cold products, diet aids, or NSAIDs such as ibuprofen/naproxen). A very serious reaction may occur if you get injections for bee/wasp sting allergy (desensitization) and are also taking lisinopril. Make sure all your doctors know which medicines you are using.
