Clenbuterol is not approved by the U.S. Food and Drug Administration (FDA) for human use [1]. It is a prescription medication approved for use in horses as a bronchodilator [2].
Why isn't Clenbuterol approved for people?
The FDA has not approved clenbuterol for human use due to safety concerns and a lack of demonstrated efficacy for common human medical conditions [1]. While it has potential bronchodilating effects, these are not considered sufficient to outweigh the risks in humans for general medical applications [1].
What are the risks of using Clenbuterol in humans?
Human use of clenbuterol, particularly at doses higher than those prescribed for animals, can lead to serious adverse effects [3]. These can include cardiovascular issues such as rapid heart rate, palpitations, and chest pain [3]. Neurological symptoms like tremors, anxiety, and dizziness are also reported [3]. Metabolic disturbances, including dangerously low potassium levels (hypokalemia), can occur [3]. There have been instances of accidental or intentional overdoses in humans, highlighting the potential for severe harm [3].
Where is Clenbuterol used instead of human medicine?
Clenbuterol is approved for veterinary use, primarily in horses, to treat respiratory conditions like recurrent airway obstruction (heaves) [2]. Its ability to open airways makes it effective in these animals [2].
Can Clenbuterol be found in dietary supplements?
Despite its lack of FDA approval for human consumption, clenbuterol has sometimes been detected in dietary supplements marketed for weight loss or athletic performance [4]. This is an illegal adulteration, and products containing clenbuterol are not safe or approved for human use [4]. The presence of clenbuterol in such supplements poses significant health risks to consumers who may be unaware of its inclusion [4].
