  • Sudden drug stoppage warning: you must continue taking the drug until your doctor says otherwise. If you stop using carvedilol suddenly, it can alter your heart rhythm, exacerbate chest pain, or a heart attack. If you need to stop the drug, your doctor will gradually reduce your dosage over one or two weeks to help avoid these effects. If your chest pain or heart problems get worse after stopping this drug, you may have to start taking it again.
  • Low heart rate warning: Carvedilol can reduce your heart rate. If your heart rate goes below 55 beats per minute, your doctor may reduce your dosage of this drug.
  • Low blood pressure warning: Carvedilol can lead to dangerously low blood pressure, which may cause you to lose consciousness. This risk is highest after your first doses and during dosing increases. To reduce the risk of this happening, use carvedilol with food. You will start on a low dosage and gradually increase it.
  • Diabetes warning: Carvedilol can lead to low blood sugar levels (hypoglycemia) and delay how long it takes your blood sugar levels to return to normal. It may also mask the signs of low blood sugar levels. This drug should be used with proper guidance if you have diabetes.
