Ephedrine — Uses, Dosage, Side Effects & Safety
Drug class: Sympathomimetic agent
Overview
Ephedrine is a medication used to treat low blood pressure (hypotension) during anesthesia, nasal congestion, and sometimes mild asthma symptoms. It works by stimulating certain receptors in your body, leading to increased heart rate, blood pressure, and opening of the airways. Ephedrine acts as a stimulant on the central nervous system and is similar in action to adrenaline. It helps constrict blood vessels and relaxes airway muscles, making it easier to breathe and improving blood flow. Patients should know that ephedrine can cause side effects such as increased heart rate, nervousness, and insomnia. It should only be used under medical supervision, especially in people with heart conditions, high blood pressure, or thyroid disorders.
