What are the side effects of epinephrine?

Epinephrine, also known as adrenaline, is a powerful medication commonly used in emergencies, such as anaphylaxis or severe asthma attacks. Its primary action is to stimulate the body's "fight or flight" response, which can lead to several predictable physiological effects.

Among these effects, tachycardia (an increased heart rate) and anxiety are significant side effects. When epinephrine is administered, it activates beta-adrenergic receptors, leading to increased heart rate and cardiac output as the body prepares to respond to stress. The stimulation of the nervous system can also result in feelings of anxiety or nervousness, as it enhances alertness and prepares the body for rapid action.

These side effects are important for first responders to recognize, as they can help distinguish the effects of epinephrine from the symptoms of the condition being treated. Understanding the manifestations of epinephrine's pharmacological effects enables first responders to monitor patients effectively and provide better care.
