ADCO Atenolol: Side Effects, Interactions, Uses, Dosage
ADCO atenolol is in a class of medications called beta blockers. It works by relaxing blood vessels and slowing heart rate to improve blood flow and decrease blood pressure. Like other beta blockers, ADCO atenolol works by changing the way your body responds to some nerve impulses, including in the heart. It slows down your heart rate and makes it easier for your heart to pump blood around your body.
What are ADCO atenolol tablets used for?
ADCO atenolol is used alone or in combination with other medications to treat high blood pressure. It also is used to prevent angina (chest pain) and improve survival after a heart attack. High blood pressure is a common condition and when not treated, can cause damage to the brain, heart, blood vessels, kidneys and other parts of the body.
Damage to these organs may cause heart disease, a heart attack, heart failure, stroke, kidney failure, loss of vision, and other problems. In addition to taking medication, making lifestyle changes will also help to control your blood pressure. These changes include eating a diet that is low in fat and salt, maintaining a healthy weight, exercising at least 30 minutes most days, not smoking, and using alcohol in moderation.
How should this medicine be used?
ADCO atenolol comes as a tablet to take by mouth. It is usually taken once or twice a day. To help you remember to take ADCO atenolol, take it around the same time(s) every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take ADCO atenolol exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
ADCO atenolol controls high blood pressure and angina but does not cure them. It may take 1-2 weeks before you feel the full benefit of atenolol. Continue to take ADCO atenolol even if you feel well. Do not stop taking atenolol without talking to your doctor.
