Q

Side Effects and Special Notes

A

Nausea, flushing of the face, and tingling; Varying degrees of AV blacks, PVCs, PACs, an asystole; Due to the very short half-life (less than 10 seconds) these effects are generally self-limiting; Significant percentage of patients complain of chest pain following administration. The chest pain is usually self-limiting lasting less than 1 minute and not angina related. Consider NTG only if pain persists longer than 1 minute; Dose should be given to the closest port to the IV site and followed by rapid flush. Documentation of the rhythm with ECG tracings prior to, during, and after administration should be obtained.
