About Emerphed


Ephedrine Sulfate injection is an alpha- and beta-adrenergic agonist and a norepinephrine-releasing agent that is indicated for the treatment of clinically important hypotension occurring in the setting of anesthesia.


Emerphed can cause pressor effects with concomitant use with oxytocic drugs. Can also cause tachyphylaxis with repeated administration of ephedrine.




Overdose of Emerphed can cause a rapid rise in blood pressure. In the case of an overdose, careful monitoring of blood pressure is recommended. If blood pressure continues to rise to an unacceptable level, parenteral antihypertensive agents can be administered at the discretion of the clinician.


Most common adverse reactions during treatment: nausea, vomiting, and tachycardia. To report SUSPECTED ADVERSE REACTIONS, contact Nexus Pharmaceuticals at (855) 642-2594 or FDA at 1-800-FDA-1088 or For full prescribing information, please see the following link.
