Dental Health: Local Anesthetic/Vasoconstrictor Precautions

Use vasoconstrictors with caution since ephedrine may enhance cardiostimulation and vasopressor effects of sympathomimetics

Dental Health: Effects on Dental Treatment

Prescribe erythromycin products with caution to patients taking theophylline products. Erythromycin will delay the normal metabolic inactivation of theophyllines leading to increased blood levels; this has resulted in nausea, vomiting, and CNS restlessness.
