Antibiotic Premedication Prior to Dental Treatments



Guidelines for Antibiotic Premedication

In certain health conditions antibiotics are given before a  dental procedure, to prevent a possible infection from occurring; this practice is calledantibiotic prophylaxis.”

Prophylactic antibiotics might be recommended before dental procedures if you have one or more of the following health conditions:

  • A heart transplant
  • Artificial heart valves
  • A history of infective endocarditis
  • Some types of congenital heart problemsparticularly if they haven’t been completely repaired, or if their treatment involves prosthetic material
  • Artificial Hip replacement
  • Artificial Knee replacement
  • Total joint replacement
  • A systemic inflammatory disease such as rheumatoid arthritis or lupus erythematosis
  • A weakened immune system resulting from HIV, cáncer, radiation or chemotherapy, or another cause
  • Insulin-dependent (type I) diabetes or hemophilia
  • A history of previous infection in a prosthetic joint
  • Undernourishment or malnourishment

There are other circumstances where taking prophylactic antibiotics would be a prudent step; there are also a number of situations where these medications might have been recommended in the past, but aren’t currently required in all cases. For example, the presence of a benign heart murmur, a pacemaker or defibrillator, and certain heart diseases or congenital defects don’t automatically mean that antibiotic prophylaxis will be needed.

In recent years, reports of drug-resistant bacteria and harmful side effects from some medications have increased public awareness of the consequences of overusing antibiotics. Afortunadamente, new scientific research is helping us make better, evidence-based treatment decisions on antibiotic use. If you have questions about whether you should take antibiotics before dental procedure, don’t hesitate to ask.
