In 2004, the U.S. Food and Drug Administration (FDA) banned the sale of dietary supplements containing ephedrine alkaloids due to safety concerns and links to serious adverse health events. However, while its widespread use was halted, the answer to 'Do doctors still prescribe ephedrine?' is a surprising yes, but for a very limited and specific purpose.

Despite being banned from dietary supplements in the United States since 2004, ephedrine is still a key medication with vital medical applications, particularly in hospital settings for treating low blood pressure.

Fact: The effect of epinephrine (also known as adrenaline) on the body is heavily dependent on the dose administered, which means it can be either a vasoconstrictor or a vasodilator.

Historically, the herbal source of ephedrine, *ma huang*, has been used in Traditional Chinese Medicine for thousands of years to treat respiratory ailments.

In 2000, the U.S. Food and Drug Administration (FDA) issued a public health advisory recommending against the use of products containing phenylpropanolamine (PPA) due to an increased risk of hemorrhagic stroke.
