For more information, consult your pharmacist.
ephedrine HCl oral Uses
Ephedrine is available in the US as a nonprescription medication for relief of breathing problems. It is rarely used because there are safer and more effective medications (e.g., albuterol, pseudoephedrine). Ma huang/ephedra is an herbal/dietary supplement that was banned by the US FDA in 2004 because it has an unreasonable risk with little proven benefit. Consult your doctor or pharmacist for more details.
Ephedrine is the active ingredient in ephedra/ma huang. It belongs to a class of medications called sympathomimetics. It works like a naturally occurring substance (adrenaline) that your body makes when it thinks it is in danger. It is a central nervous system stimulant that increases your heart rate/blood pressure, narrows your blood vessels (vasoconstriction), and opens up the lungs (bronchodilation).
Some herbal/diet supplement products have been found to contain possibly harmful impurities/additives. The amount of medication may be very different between products. Check with your pharmacist for more details about the particular brand you use.How to use ephedrine HCl oral
