How do you take this medication?
Take Coreg CR by mouth with food, usually once daily in the mornings.
High blood pressure is a long-term (chronic) condition that can harm your organs. Medications for blood pressure are not a one-time cure. This medicine doesn't provide a complete cure for high blood pressure, so it's important to continue taking it, even if you start feeling better. If you stop taking it suddenly, this could cause dangerous problems, like heart attack or stroke. Follow your medical provider's instructions carefully.
What happens if I miss a dose?
If you miss a dose of your hypertension pill, take it as soon as you remember. If it's close to the time for your next dose, skip the missed one. Do not double the dose to make up for the missed one.
What happens if I take too much?
Taking too much of your blood pressure medicine can lead to symptoms like slow or irregular heart rate, low blood pressure, hypoglycemia (low blood sugar), and difficulty breathing.
If you’ve taken too much Coreg CR, call your licensed medical provider or local poison control center (800-222-1222) immediately.
