What happens if I miss a dose (Coreg)?

Take the missed dose as soon as you remember. If your next dose is less than 4 hours away, skip the missed dose and take the medicine at the next regularly scheduled time. Do not take extra medicine to make up the missed dose.

What happens if I overdose (Coreg)?

Seek emergency medical attention if you think you have used too much of this medicine.

Overdose symptoms may include uneven heartbeats, shortness of breath, bluish-colored fingernails, dizziness, weakness, fainting, and seizure (convulsions).

What should I avoid while taking carvedilol (Coreg)?

Carvedilol can cause side effects that may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be awake and alert.

Avoid drinking alcohol within 2 hours before or after taking extended-release carvedilol (Coreg CR). Also avoid taking medicines or other products that might contain alcohol. Alcohol may cause the carvedilol in Coreg CR to be released too quickly into the body. Check the labels of any prescription or over-the-counter medicines you take to see if they contain alcohol (also called ethanol).

Avoid getting up too fast from a sitting or lying position, or you may feel dizzy. Get up slowly and steady yourself to prevent a fall.
