A 32 year-old male comes to your office inquiring about antibiotic prophylaxis for endocarditis before a dental procedure. He reports a history of repaired congenital cyanosis heart disease when he was 5 years-old. He has been asymptomatic since his surgery. He is allergic to penicillins. Physical examination is unremarkable. What would be the best advice to this patient concerning antibiotic prophylaxis?
