Antibiotic prophylaxis for infective endocarditis is still debated because of unproven efficacy and risk of side effects. French recommendations for infective endocarditis prophylaxis were revised in 2002 and its indications were restricted.
Several arguments plead against prophylaxis: the absence of scientific evidence of its efficacy, the very high number of antibiotic doses required to prevent a very small number of endocarditis, the possible failure of prophylaxis even if correctly administered and a lack of compliance with current recommendations. High-risk patients for whom dental extraction is required should receive prophylaxis. For moderate-risk patients, prophylaxis is optional and should be discussed for each case individually.
Although prophylaxis is discussed, one should focus on prevention measures, such as dental hygiene and education of physicians, dentists and patients.
