Blood Pressure

Drug Uses

Coreg is prescribed for the treatment of high blood pressure but it may also be prescribed to increase the chances of survival in people who have suffered a heart attack.

Usage

There are two versions of Coreg. The generic version should be taken twice a day with food whereas the extended release version called Coreg CR, should be taken once a day in the morning with food.

Missed Dose

You should try and not miss any doses of Coreg. But if you do miss a dose then take it as soon as you remember. However, if it is nearly the time for your next dose, skip the one you missed and go back to your regular schedule. Do not take a double dose at once.

Storage

Coreg should be stored in a tight container away from light and heat.

Overdose

Some of the typical symptoms of a Coreg overdose include breathing difficulties, loss of consciousness, seizures, heart problems, slow heartbeat, very low blood pressure and vomiting. If you suspect an overdose, then seek medical attention immediately.

More Information

People suffering from chronic bronchitis and emphysema should maintain caution while taking Coreg because it is known to aggravate these conditions. The effects may worsen if you consume alcohol while taking the drug. Ensure that you discuss your complete medical history with your doctor before taking the drug.
