Complicated hypertension related to the abuse of ephedrine and caffeine alkaloids.

Ephedra containing products (ECPs), which most often contain additional sources of caffeine alkaloids, may be an under-recognized cause of hypertension. ECPs, especially when used in combination or at higher than recommended doses, can cause life-threatening cardiovascular and neurological complications. We present a case of hypertensive encephalopathy with new onset generalized tonic-clonic seizure secondary to concomitant use of two OTC supplements containing a mixture of ephedrine and caffeine alkaloids.
