The maximum single IV push dose of Metoprolol (Lopressor) is 5 mg. Administer slowly over at least 2 minutes to minimize the risk of hypotension and bradycardia. Repeat doses should be given cautiously and separated by at least 5-10 minutes, depending on patient response and hemodynamic stability.
Titration is key. Monitor blood pressure and heart rate closely. Adjust subsequent doses based on the patient’s response, aiming for a controlled reduction in heart rate and blood pressure.
For patients with significant cardiovascular compromise or those who are elderly or frail, consider starting with a lower dose (e. g., 2.5 mg) and titrating very gradually.
Here’s a table summarizing key considerations:
| Maximum Single Dose | 5 mg |
| Administration Rate | Over at least 2 minutes |
| Time Between Doses | 5-10 minutes, depending on response |
| Elderly/Frail Patients | Start with lower dose (e. g., 2.5 mg) |
| Monitoring | Continuous blood pressure and heart rate monitoring |
Always reassess the patient’s condition after each dose. Discontinue administration if significant hypotension or bradycardia develops. Be prepared to treat adverse effects promptly.
