About EMERPHED® Ready-To-Use Ephedrine Sulfate Injection

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.
