Abstract

This case-control study examined the association between Ephedra use and risk for hemorrhagic stroke. For use of Ephedra at any dose during the 3 days before the stroke, the adjusted OR was 1.00 (95% CI 0.32 to 3.11). For daily doses of ≥32 mg/day, the OR was 0.13 (95% CI 0.01 to 1.54), and for >32 mg/day, the OR was 3.59 (95% CI 0.70 to 18.35). Ephedra is not associated with increased risk for hemorrhagic stroke, except possibly at higher doses.
