MedDataToolCoreg CR is a medication used to treat conditions like chronic heart failure, left ventricular dysfunction after a heart attack, and high blood pressure. It works by blocking certain receptors in the body, which helps to lower blood pressure and improve heart function. You take it as an extended-release capsule once a day, starting at 10 mg for heart failure or 20 mg for high blood pressure, and it can be increased to a maximum of 80 mg if needed. It's important to know that Coreg CR should not be taken if you have severe liver problems or asthma. Additionally, if you're taking medications like digoxin, be aware that Coreg CR can increase the levels of digoxin in your body.
