Ephedra: Reactions with other drugs or substances

Ephedra supplements typically contain caffeine, and users may consume caffeine in carbonated beverages, coffee, or tea. Researchers suspect that caffeine may enhance ephedra’s stimulant effects on cardiovascular and/or central nervous system responses. This may account for the types of adverse events that have been reported by ephedra users.
When ephedra is used in combination with decongestants or other nervous system stimulants, the effect on the nervous system may be increased.
Ephedra has negative interactions with cardiac heart glycosides, halothene, guanethidine, MAO inhibitors, and secale alkaloid derivatives or oxytocin.
