Warnings and Precautions
- Serious postpartum hypertension can occur in patients also receiving both a vasopressor and an oxytocic. Some patients experienced a stroke.
- Repeated administration of ephedrine can result in tachyphylaxis. An alternative pressor may be needed to mitigate unacceptable responsiveness.
- When used to prevent hypotension, ephedrine can cause an increased incidence of hypertension compared to when used to treat hypotension.

Drug Interactions
- Agonistic Effects (increase in Rezipres blood pressure effect) can occur with clonidine, oxytocin and oxytocic drugs, monoamine oxidase inhibitors (MAOI), and atropine.
- Antagonistic Effects (decrease in Rezipres blood pressure effect) can occur with α-adrenergic antagonists, β-adrenergic antagonists, reserpine, quinidine, mephentermine.
- Inhibition of the neuron blockage produced by guanethidine can occur resulting in loss of antihypertensive effectiveness.
- Reduction in the onset time of neuromuscular blockade can occur when used for intubation with rocuronium if administered simultaneously with anesthetic induction.
- The efficacy of epidural blockade can be decreased by hastening the regression of sensory analgesia.
- Concomitant use of theophylline may increase the frequency of nausea, nervousness, and insomnia.
- Concomitant use of a cardiac glycoside, such as digitalis, may increase the possibility of arrhythmias.
