For prescription ephedrine, do not exceed 150 mg per day in adults or 75 mg per day in children. Do not combine prescription ephedrine with ephedrine/ephedra/ma huang from dietary supplement products, since they are the same medicine. Use this medication exactly as prescribed. Do not increase your dose, take it more frequently, or use it for a longer period of time than prescribed because this drug can be habit-forming and you may increase for your risk for serious side effects.

Your doctor may recommend "drug holidays" where your medication is stopped temporarily. Doing so may help this medication work more effectively.
