Uses For lisinopril
Lisinopril is used alone or together with other medicines to treat high blood pressure (hypertension). High blood pressure adds to the workload of the heart and arteries. If it continues for a long time, the heart and arteries may not function properly. This can damage the blood vessels of the brain, heart, and kidneys resulting in a stroke, heart failure, or kidney failure. Lowering blood pressure can reduce the risk of strokes and heart attacks.
Lisinopril works by blocking a substance in the body that causes the blood vessels to tighten. As a result, lisinopril relaxes the blood vessels. This lowers blood pressure and increases the supply of blood and oxygen to the heart.
Lisinopril is also used to help treat heart failure. It is also used in some patients after a heart attack. After a heart attack, some of the heart muscle is damaged and weakened. The heart muscle may continue to weaken as time goes by. This makes it more difficult for the heart to pump blood. Lisinopril may be started within 24 hours after a heart attack to increase survival rate.
lisinopril is available only with your doctor's prescription.
Before Using lisinopril
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For lisinopril, the following should be considered:
Tell your doctor if you have ever had any unusual or allergic reaction to lisinopril or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
Appropriate studies performed to date have not demonstrated pediatric-specific problems that would limit the usefulness of lisinopril to treat hypertension in children 6 to 16 years of age. However, safety and efficacy have not been established in children younger than 6 years of age.
Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of lisinopril in the elderly. However, elderly patients are more likely to have age-related kidney problems, which may require caution and an adjustment in the dose for patients receiving lisinopril.
There are no adequate studies in women for determining infant risk when using this medication during breastfeeding. Weigh the potential benefits against the potential risks before taking this medication while breastfeeding.

Proper Use of lisinopril

Therefore, you must continue to take it as directed if you expect to lower your blood pressure and keep it down. You may have to take high blood pressure medicine for the rest of your life. If high blood pressure is not treated, it can cause serious problems such as heart failure, blood vessel disease, stroke, or kidney disease.

Precautions While Using lisinopril
It is very important that your doctor check your progress at regular visits to make sure lisinopril is working properly. Blood tests may be needed to check for unwanted effects.
Using lisinopril while you are pregnant can harm your unborn baby. Use an effective form of birth control to keep from getting pregnant. If you think you have become pregnant while using lisinopril, tell your doctor right away.
lisinopril may cause serious types of allergic reactions, including anaphylaxis. Anaphylaxis can be life-threatening and requires immediate medical attention. Call your doctor right away if you have a rash, itching, hoarseness, trouble breathing, trouble swallowing, or any swelling of your hands, face, mouth, or throat while you are using lisinopril.
Call your doctor right away if you have severe stomach pain (with or without nausea or vomiting). This could be a symptom of intestinal angioedema.
Dizziness, lightheadedness, or fainting may also occur, especially when you get up from a lying or sitting position or if you have been taking a diuretic (water pill). Make sure you know how you react to the medicine before you drive, use machines, or do other things that could be dangerous if you are dizzy or not alert. If you feel dizzy, lie down so you do not faint. Then sit for a few moments before standing to prevent the dizziness from returning.
Check with your doctor right away if you become sick while taking lisinopril, especially with severe or continuing nausea, vomiting, or diarrhea. These conditions may cause you to lose too much water or salt and may lead to low blood pressure. You can also lose water by sweating, so drink plenty of water during exercise or in hot weather.
Check with your doctor if you have a fever, chills, or sore throat. These could be symptoms of an infection resulting from low white blood cells.
Hyperkalemia (high potassium in the blood) may occur while you are using lisinopril. Check with your doctor right away if you have the following symptoms: abdominal or stomach pain, confusion, difficulty with breathing, irregular heartbeat, nausea or vomiting, nervousness, numbness or tingling in the hands, feet, or lips, shortness of breath, or weakness or heaviness of the legs. Do not use supplements or salt substitutes containing potassium without first checking with your doctor.
Check with your doctor right away if you have upper stomach pain, pale stools, dark urine, loss of appetite, nausea, unusual tiredness or weakness, or yellow eyes or skin. These could be symptoms of a serious liver problem.
lisinopril may affect blood sugar levels. If you notice a change in the results of your blood or urine sugar tests, or if you have any questions, check with your doctor.
Make sure any doctor or dentist who treats you knows that you are using lisinopril. You may need to stop using lisinopril several days before having surgery.
lisinopril may be less effective in black patients. Black patients also have an increased risk of angioedema (swelling of the hands, arms, face, mouth, or throat).
Do not take other medicines unless they have been discussed with your doctor. This includes over-the-counter (nonprescription) medicines for appetite control, asthma, colds, cough, hay fever, or sinus problems, since they may tend to increase your blood pressure.
