What is Atacand?
Atacand (candesartan) is an angiotensin II receptor antagonist. Candesartan keeps blood vessels from narrowing, which lowers blood pressure and improves blood flow.
Atacand is used to treat high blood pressure (hypertension) in adults and children who are at least 1 year old. Lowering blood pressure can reduce the risk of stroke, heart attack, or other heart complications.
Atacand is also used in adults with certain types of heart failure, to reduce serious complications or death due to heart damage.
Do not use if you are pregnant. Stop using Atacand and tell your doctor right away if you become pregnant.
If you have diabetes, do not use Atacand together with any medication that contains the blood pressure medicine aliskiren (e.g. Amturnide, Tekturna, Tekamlo>.
Before taking this medicine
You should not use Atacand if you are allergic to candesartan.
If you have diabetes, do not use Atacand together with any medication that contains aliskiren (a blood pressure medicine).
You may also need to avoid taking candesartan with aliskiren if you have kidney disease.
To make sure Atacand is safe for you, tell your doctor if you have:
kidney disease (or if you are on dialysis);
if you are on a low-salt diet; or
if you are dehydrated.
Do not use if you are pregnant. If you become pregnant, stop taking this medicine and tell your doctor right away. Candesartan can cause injury or death to the unborn baby if you take the medicine during your second or third trimester.
You should not breast-feed while using this medicine.
How should I take Atacand?
Take Atacand exactly as prescribed by your doctor. Follow all directions on your prescription label and read all medication guides or instruction sheets. Your doctor may occasionally change your dose.
You may take Atacand with or without food.
Tell the doctor if a child taking this medicine has trouble swallowing the tablet.
Your blood pressure will need to be checked often. You may also need frequent medical tests.
If you need surgery, tell the surgeon ahead of time that you are using Atacand. You may need to stop using the medicine for a short time.
It may take up to 4 weeks before your blood pressure is under control. Keep using Atacand as directed, and talk with your doctor if your blood pressure does not improve after 2 weeks of treatment.
If you have high blood pressure, keep using this medicine even if you feel well. High blood pressure often has no symptoms. You may need to use blood pressure medicine for the rest of your life.
