Which antibiotic is commonly used for dental prophylaxis in at-risk endocarditis patients, and what is the standard dose?

Dental prophylaxis for at-risk endocarditis patients relies on giving antibiotics before dental work to cover the transient bacteremia that can seed abnormal heart valves. Amoxicillin is preferred because its oral bioavailability provides reliable tissue and serum levels. The standard preventive dose is 2 g taken by mouth about 30 to 60 minutes before the procedure. If penicillin allergy is present, clindamycin 600 mg is the commonly recommended alternative given in the same pre-procedure window. The other options don’t fit because they use an incorrect dose, timing, or omit an appropriate allergy alternative, which would not provide proper protection.
