Prevention

You can take the following steps to help prevent endocarditis:

• Know the signs and symptoms of endocarditis. See your doctor immediately if you develop any signs or symptoms, especially a fever that won't go away, unexplained fatigue, any type of skin infection, or open cuts or sores that don't heal properly.
• Take care of your teeth and gums. Brush and floss your teeth and gums often, and have regular dental checkups. Good dental hygiene is an important part of maintaining your overall health.
• Don't use illegal IV drugs. Dirty needles can send bacteria into your bloodstream, increasing your risk of endocarditis.

Preventive antibiotics

Certain dental and medical procedures may allow bacteria to enter your bloodstream.

If you're at high risk of endocarditis, the American Heart Association recommends taking antibiotics an hour before having any dental work done.

You're at high risk of endocarditis and need antibiotics before dental work if you have:

• A history of endocarditis
• A man-made (prosthetic mechanical) heart valve
• A heart transplant, in some cases
• Certain types of congenital heart disease
• Congenital heart disease surgery in the last six months

If you have endocarditis or any type of congenital heart disease, talk to your doctor and dentist about your risks and whether you need preventive antibiotics.
