If the condition you are taking the beta blocker is under control, (for example irregular heart rate or high Blood pressure) then yes it would be prudent to stop the beta blocker for < 1 day. Although -caine allergy is rare, and usually due to the preservative, there could be an outside chance that a systemic reaction could occur, with a patient's breathing being compromised.

Can you take metoprolol tartrate and lidiocaine and vicodin?

You can take these drugs together. There is a moderate druginteraction between the metoprolol and the lidocaine. Metoprolol is a beta-blocker. Some beta-blockers may increase lidocaine levels and risk of toxicity. The proposed mechanism is enzyme inhibition and/or decreased cardiac output and hepatic blood flow resulting in decreased hepatic metabolism of lidocaine. In addition beta-blockers and lidocaine may also have additive negative inotropic effects on the heart. Data have been conflicting and variable. While taking these 2 drugs together, I would watch the following below: Patients receiving concurrent therapy should be monitored for drowsiness, mental status changes, bradycardia, and hypotension. Lidocaine levels should be obtained when clinically necessary. If toxicity is suspected, the lidocaine infusion should be decreased, as possible.
