What is the preferred prophylaxis for dental procedures to prevent infective endocarditis?

  1. Ciprofloxacin 500mg

  2. Amoxicillin 2g

  3. Doxycycline 100mg

  4. Nafcillin 1g

The correct answer is: Amoxicillin 2g

The reason why this is the preferred prophylaxis is because Amoxicillin is an antibiotic that covers for most common bacteria found in the oral cavity that can cause infective endocarditis. Ciprofloxacin, Doxycycline, and Nafcillin do not specifically target these bacteria and may not be effective in preventing infective endocarditis. Additionally, these antibiotics may have more side effects and are not the recommended first-line treatment for this condition. It is important to follow the recommended prophylaxis guidelines to prevent unnecessary complications.
