How to prevent bacterial endocarditis?
Prophylactic antibiotics may be prescribed by your doctor or dentist before you have any medical or dental procedure in which bacteria have a chance of entering your blood, thus to prevent endocarditis that may result from a damaged heart valve or other medical problems.
Prophylactic antibiotics are usually given to people with artificial valves, previous medical history of endocarditis and other high-risk conditions. Most people with mitral valve prolapse and other minor abnormalities of heart structure do not need antibiotics before medical or dental procedures.
Generally, antibiotics are given one to two hours before a high-risk procedure, and up to eight hours afterward.
Before a dental procedure, an antiseptic mouth rinse (especially one containing chlorhexidine or povidone-iodine) can also be used. What’s more, avoiding IV drug use can also prevent endocarditis.
