MedDataToolCarvedilol phosphate is a medication used to treat conditions like chronic heart failure, high blood pressure, and heart issues after a heart attack. It works by blocking certain receptors in the body, which helps to lower blood pressure and improve heart function. You take it as a capsule once a day, starting at a dose of 10 mg for heart failure or 20 mg for high blood pressure, with a maximum dose of 80 mg. It's important to know that this medication should not be taken if you have severe liver problems or asthma. Additionally, it can interact with other medications, so be cautious if you're taking drugs like amiodarone, as it can increase the levels of carvedilol in your body.
