See also Warning and Precautions sections.

Dizziness, lightheadedness, drowsiness, diarrhea, impotence, or tiredness may occur. If any of these effects persist or worsen, tell your doctor or pharmacist promptly.

To reduce the risk of dizziness and lightheadedness, get up slowly when rising from a sitting or lying position. The risk of dizziness is highest within 1 hour after you take your dose. Taking this medication with food and starting treatment with a low dose and slowly increasing your dose as directed by your doctor help to reduce the risk of dizziness.

This drug may reduce blood flow to your hands and feet, causing them to feel cold. Smoking may worsen this effect. Dress warmly and avoid tobacco use.

Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.

Tell your doctor right away if you have any serious side effects, including: very slow heartbeat, severe dizziness, fainting, unusual weakness, signs of kidney problems (such as change in the amount of urine), numbness/tingling of the hands/feet, blue fingers/toes, easy bruising/bleeding, mental/mood changes (such as confusion, depression), seizures.

Although this medication may be used to treat heart failure, some people may rarely develop new or worsening symptoms of heart failure, especially at the start of carvedilol treatment. Tell your doctor right away if you develop any of these serious side effects: shortness of breath, swelling ankles/feet, unusual tiredness, unusual/sudden weight gain.

A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.
