Ephedrine sulfate injection is indicated for the treatment of clinically important hypotension occurring in the setting of anesthesia. 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.

Pressor Effects with Concomitant Use with Oxytocic Drugs : Pressor effect of sympathomimetic pressor amines is potentiated ( 5.1 ) Tachyphylaxis and Tolerance : Repeated administration of ephedrine may cause tachyphylaxis ( 5.2 ) 5.1 Pressor Effect with Concomitant Oxytocic Drugs Serious postpartum hypertension has been described in patients who received both a vasopressor (i.e., methoxamine, phenylephrine, ephedrine) and an oxytocic (i.e., methylergonovine, ergonovine) [see Drug Interactions (7) ] . Some of these patients experienced a stroke. Carefully monitor the blood pressure of individuals who have received both ephedrine and an oxytocic. 5.2 Tolerance and Tachyphylaxis Data indicate that repeated administration of ephedrine can result in tachyphylaxis. Clinicians treating anesthesia-induced hypotension with ephedrine sulfate injection should be aware of the possibility of tachyphylaxis and should be prepared with an alternative pressor to mitigate unacceptable responsiveness. 5.3 Risk of Hypertension When Used Prophylactically When used to prevent hypotension, ephedrine has been associated with an increased incidence of hypertension compared with when ephedrine is used to treat hypotension.

8.1 Pregnancy Risk Summary Available data from randomized studies, case series, and reports of ephedrine sulfate use in pregnant women have not identified a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes. However, there are clinical considerations due to underlying conditions (see Clinical Considerations ) . In animal reproduction studies, decreased fetal survival and fetal body weights were observed in the presence of maternal toxicity after normotensive pregnant rats were administered 60 mg/kg intravenous ephedrine sulfate (12 times the maximum recommended human dose (MRHD) of 50 mg/day). No malformations or embryofetal adverse effects were …
