Dosage With Metoprolol Tartrate
For people with high blood pressure, the recommended metoprolol tartrate dose is 100 mg once daily or 50 mg twice daily. The suggested starting dosage for the relief of angina symptoms is 50 mg twice a day. Immediately following a heart attack, metoprolol tartrate may be administered through an intravenous line to improve survival. Factors that can affect your dosage include your age, other medical conditions you may have, and other drugs you may be taking.
The dose of metoprolol tartrate (Lopressor®) 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 metoprolol tartrate.
As always, do not adjust your dose unless your healthcare provider specifically instructs you to do so.
The recommended starting dosage of metoprolol tartrate 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 side effects or metoprolol tartrate. Your healthcare provider may also add a diuretic (a "water pill") or another blood pressure medication if your blood pressure is not controlled by metoprolol tartrate alone.
Sometimes taking the medication 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 metoprolol tartrate twice a day or increase the once-daily dosage.
The maximum recommended daily dose of metoprolol tartrate for this use is 450 mg.
