WARNING: This drug should not be used in combination with other stimulant products (e.g., caffeine), other cough-and-cold products, or as a dietary supplement for the purpose of weight loss or body building.

In addition, dietary supplements containing ephedra should not exceed 8 mg as a single ephedra dose, 24 mg of ephedra per day (24 hours), or be given for longer than 7 days, as recommended by the FDA. Exceeding the recommended ephedra dose increases your risk of the side effects noted above. For detailed information, consult your pharmacist. Check all product labels carefully to see if they contain ephedrine or ephedra/ma huang, which are all very similar; do not combine them.
