Carteolol Oral (patient information)
IMPORTANT WARNING
Do not stop taking carteolol without talking to your doctor first. If carteolol is stopped suddenly, it may cause chest pain or heart attack in some people.
Why this medication is prescribed
Carteolol is used to treat high blood pressure. It works by relaxing your blood vessels so your heart doesn't have to pump as hard.
This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.
How this medication should be used
Carteolol comes as a tablet to take by mouth. It is usually taken once a day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take carteolol exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Carteolol helps control your condition but will not cure it. Continue to take carteolol even if you feel well. Do not stop taking carteolol without talking to your doctor.
