What are the uses of this medicine?[edit | edit source]

How does this medicine work?[edit | edit source]

  • Ephedrine sulfate is a sympathomimetic amine that directly acts as an agonist at α- and ß­ adrenergic receptors and indirectly causes the release of norepinephrine from sympathetic neurons.
  • Pressor effects by direct alpha- and beta-adrenergic receptor activation are mediated by increases in arterial pressures, cardiac output, and peripheral resistance.
  • Indirect adrenergic stimulation is caused by norepinephrine release from sympathetic nerves.

What side effects can this medication cause?[edit | edit source]

The most common side effects of this medicine include:

  • Some patients have nausea, vomiting and anorexia. Vesical sphincter spasm may occur and result in difficult and painful urination. Urinary retention may develop in males with prostatism.
  • Primordial pain and cardiac arrhythmias may occur following administration of Ephedrine Sulfate Injection, USP

What special precautions should I follow?[edit | edit source]

  • 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). Some of these patients experienced a stroke. Carefully monitor the blood pressure of individuals who have received both ephedrine and an oxytocic.
  • 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.
  • When used to prevent hypotension, ephedrine has been associated with an increased incidence of hypertension compared with when ephedrine is used to treat hypotension.
  • Special care should be used when administering Ephedrine Sulfate Injection, USP to patients with heart disease, angina pectoris, diabetes, hyperthyroidism, prostatic hypertrophy or hypertension and to patients receiving digitalis.
  • Prolonged use may produce a syndrome resembling an anxiety state. Tolerance to ephedrine sulfate may develop, but temporary discontinuance to the drug restores its original effectiveness.

What to do in case of emergency/overdose?[edit | edit source]

Symptoms of overdosage may include:

Management of overdosage:

  • In case of overdose, call the poison control helpline of your country. In the United States, call 1-800-222-1222.

  • 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.
  • If respirations are shallow or cyanosis is present, artificial respiration should be administered.
  • Vasopressors are contraindicated.
  • In cardiovascular collapse blood pressure should be maintained.
  • For hypertension, 5 mg phentolamine mesylate diluted in saline may be administered slowly intravenously, or 100 mg may be given orally.
