Additional information

If you are taking an immediate release form of metoprolol, it is best taken with a full glass of water. You can take all forms of metoprolol succinate with or without food, but try to take it the same way each time: always take it with food or always take it on an empty stomach.

You may not be able to feel the benefit of metoprolol. Do not stop taking metoprolol unless you are instructed to by your doctor.

Taking your blood pressure medications as directed is important in decreasing your risk for heart attack or stroke. Stopping metoprolol abruptly can cause extreme side effects including chest pain and even heart attack.

You may feel dizzy while taking metoprolol. If you have a lot of dizzy episodes or pass out, talk to your doctor, as your blood pressure may be too low.

You may feel very fatigued when you begin taking metoprolol. While this side effect is unpleasant, it typically does go away with time.

If you have diabetes, metoprolol can mask the signs of low blood sugar. Test your blood sugar regularly and take the proper steps if your blood sugar levels are low, even if you don’t feel symptoms.
