Final answer:
Amoxicillin is recommended for prophylaxis in patients undergoing dental procedures, especially those at high risk for bacterial endocarditis. It should be administered 30 to 60 minutes before the procedure. Clindamycin is an alternative for patients with penicillin allergy.
Step-by-step explanation:
The antibiotic recommended for prophylaxis in patients undergoing dental procedures primarily to prevent endocarditis includes amoxicillin. This is advised for individuals who are at high risk for bacterial endocarditis due to a history of heart conditions. The American Heart Association recommends that prophylactic antibiotic treatment, such as amoxicillin, should be administered as a single dose 30 to 60 minutes before the dental procedure.In cases of penicillin allergy, alternatives like clindamycin, azithromycin, or clarithromycin can be considered. It is essential to be aware of the potential risks associated with using antibiotics, including allergic reactions or development of antibiotic-resistant bacteria, which is why their use must be judicious and in accordance with established guidelines.
