Summary
Carvedilol is used to treat high blood pressure, which is when the force of blood against artery walls is too high, and heart failure, which is when the heart can't pump blood effectively. It also reduces the risk of death in people who have had a heart attack.
Carvedilol works by blocking certain receptors in the heart and blood vessels, which helps lower blood pressure and improve heart function. This reduces the heart's workload and helps it pump blood more effectively.
Carvedilol is usually taken twice daily with food to help absorption. The starting dose is typically 3.125 mg twice daily, with possible gradual increases. The maximum dose is 25 mg twice daily for those under 85 kg and 50 mg for those over 85 kg.
Common side effects of Carvedilol include dizziness, which is a feeling of being unsteady, fatigue, which is extreme tiredness, and low blood pressure, which is when blood pressure drops too low. These effects are usually mild and improve over time.
Carvedilol can cause low blood pressure, especially when standing up quickly, leading to dizziness or fainting. It may affect blood sugar levels, so people with diabetes should monitor closely. It should not be stopped suddenly without medical advice.

Carvedilol works by blocking certain receptors in your heart and blood vessels, which helps lower blood pressure and improve heart function. Think of it like turning down the volume on a loudspeaker. By blocking these receptors, Carvedilol reduces the force and rate of your heartbeats, which lowers blood pressure and decreases the heart's workload. This makes it helpful for people with high blood pressure and heart failure, which is when your heart can't pump blood effectively. Carvedilol also has antioxidant properties, which may provide additional heart protection.
