Intravenous (IV) sedatives are medications administered directly into the bloodstream to help patients relax or sleep during medical procedures. They work quickly, providing rapid sedation and reducing anxiety, making them useful in settings like hospitals or dental offices. These sedatives can vary in strength and duration, depending on the specific drug used. Common examples include midazolam and propofol. Medical professionals carefully monitor patients while they receive IV sedatives to ensure safety and effectiveness, adjusting dosages as needed.
