Ephedrine is indicated to reverse hypotension induced by spinal or epidural anaesthesia. It is of little value in hypotensive crisis due to shock, circulatory collapse, or haemorrhage.

Ephedrine has also been given by intramuscular or subcutaneous injection.
Ephedrine should be given with care to patients with hyperthyroidism, diabetes mellitus, ischemic heart disease, hypertension, renal impairment, or angle-close glaucoma. In patients with prostatic enlargement, Ephedrine may increase difficulty with micturition. Use in pregnancy and lactation: Increased fetal heart rate reported with parenteral Ephedrine.
