When treating symptoms of angina, dosing with Lopressor typically starts at 50 mg twice a day. The suggested starting dosage for high blood pressure control is 100 mg once daily or 50 mg twice a day. Following a heart attack, Lopressor may be given in the hospital through an intravenous line to help improve survival. Besides the medical condition being treated, other factors that can affect your dosage include your age and how you respond to Lopressor.
The dose of Lopressor® (metoprolol tartrate) your healthcare provider prescribes will vary, depending on a number of factors, including:
- Your age
- The medical condition being treated
- Other medical conditions you may have
- Other medications you may be currently taking
- How you respond to Lopressor.
As always, do not adjust your dose unless your healthcare provider specifically instructs you to do so.
Lopressor Dosage for High Blood PressureThe recommended starting Lopressor dosage for people with high blood pressure (hypertension) is 100 mg once a day or 50 mg twice a day. After a week or longer, your healthcare provider may increase or decrease your dosage based on the blood pressure response and/or Lopressor side effects. Your healthcare provider may also add a diuretic (a "water pill") or another blood pressure medication if your blood pressure is not controlled by Lopressor alone.
Sometimes, taking Lopressor once a day does not adequately control blood pressure for a full 24 hours. This is particularly common at low dosages (such as 100 mg a day). If this occurs, there are two different options -- take Lopressor twice a day or increase the once-daily dosage.
The maximum recommended daily dose of Lopressor for this use is 450 mg.
