Uses of This Medicine:

Candesartan is used alone or together with other medicines to treat high blood pressure (hypertension) in adults and children 1 to 16 years of age. 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.

Candesartan is also used to treat heart failure in adults and cut down on the number of hospital visits for heart problems.

Candesartan is an angiotensin II receptor blocker (ARB). It works by blocking the action of a substance in the body that causes the blood vessels to tighten. As a result, candesartan relaxes the blood vessels. This lowers blood pressure and increases the supply of blood and oxygen to the heart.

This medicine is available only with your doctor's prescription.

Before Using This Medicine:

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 this medicine, the following should be considered:

Allergies

Tell your doctor if you have ever had any unusual or allergic reaction to this medicine 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.

Children

Appropriate studies performed to date have not demonstrated pediatric-specific problems that would limit the usefulness of candesartan to treat hypertension in children 1 to 16 years of age.

Use of candesartan to treat hypertension in newborn babies and infants up to 1 year of age is not recommended.

No information is available on the relationship of age to the effects of candesartan to treat heart failure in the pediatric population. Safety and efficacy have not been established.

Older adults

Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of candesartan in the elderly. However, elderly patients may be more sensitive to the effects of candesartan than younger adults.

Pregnancy

Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. When you are taking this medicine, it is especially important that your healthcare professional know if you are taking any of the medicines listed below. The following interactions have been selected on the basis of their potential significance and are not necessarily all-inclusive.

Proper Use of This Medicine:

This medicine comes with a patient information insert. Read the information carefully and make sure you understand it before taking this medicine. Ask your doctor if you have any questions.

In addition to the use of this medicine, treatment for your high blood pressure may include weight control and changes in the types of foods you eat, especially foods high in sodium (salt). Your doctor will tell you which of these are most important for you. You should check with your doctor before changing your diet.

Many patients who have high blood pressure will not notice any signs of the problem. In fact, many may feel normal. It is very important that you take your medicine exactly as directed and that you keep your appointments with your doctor even if you feel well.

Remember that this medicine will not cure your high blood pressure, but it does help control it. 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.

This medicine also works best when there is a constant amount in the blood. To help keep the amount constant, do not miss any doses. Also, it is best to take the doses at the same time each day.

You may take this medicine with or without food.

If your child cannot swallow the tablets, an oral liquid may be given. Ask your doctor or pharmacist about this.

Dosing

The dose of this medicine will be different for different patients. Follow your doctor's orders or the directions on the label. The following information includes only the average doses of this medicine. If your dose is different, do not change it unless your doctor tells you to do so.

The amount of medicine that you take depends on the strength of the medicine. Also, the number of doses you take each day, the time allowed between doses, and the length of time you take the medicine depend on the medical problem for which you are using the medicine.

Precautions While Using This Medicine:

It is very important that your doctor check the progress of you or your child at regular visits to make sure that this medicine is working properly. Blood tests may be needed to check for unwanted effects.

Using this medicine 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 this medicine, tell your doctor right away.

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 this medicine before you drive, use machines, or do anything else 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 or your child become sick while taking this medicine, 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.

Before having any kind of surgery (including dental surgery) or emergency treatment, tell the doctor or dentist in charge that you are taking this medicine.

Ask your doctor before you use medicines, supplements, or salt substitutes that contain potassium.

Black patients may have a smaller response to the blood pressure-lowering effects of candesartan.

Do not take other medicines unless they have been discussed with your doctor. This especially includes prescription or nonprescription (over-the-counter) medicines for appetite control, asthma, colds, cough, hay fever, or sinus problems, since they may tend to increase your blood pressure.
