    22.2 Antibiotics Indications

    22.2.1 Precautions for All Antibiotics

    • Note that all antibiotics have the potential to interfere with oral contraceptives. Patients should be advised to take additional precautions when taking antibiotics and oral contraceptives together.
    • Antibiotics can cause “nuisance” diarrhea which is nonthreatening. Patient should call the prescriber before discontinuing the medication.
    • In general all antibiotics have the potential of causing pseudomembranous colitis which manifests itself as severe diarrhea. The patient should be instructed to discontinue use of medication and seek treatment from their physician.
    • In dentistry, antibiotic use should be limited to 7–10 days. Patients should be encouraged to seek treatment for their dental problems or return if their symptoms persist. Short term use of antibiotics will also prevent superinfections with fungal growth. Guidelines for Antibiotic Prophylaxis

    • For current guidelines on antibiotic prophylaxis for prevention of infective endocarditis, visit the American Dental Association(ADA) and the American Heart Association website at: ​www.​ada.​org/​en/​member-center/​oral-health-topics/​antibiotic-prophylaxis and ​www.​heart.​org/​HEARTORG/​Conditions/​CongenitalHeartD​efects/​TheImpactofConge​nitalHeartDefect​s/​Infective-Endocarditis_​UCM_​307108_​Article.​jsp#.​Vmrz1LgrK7Q.

      Cardiac Conditions for Which Prophylaxis with Antibiotics for Dental Procedures Is Recommended (AHA Guidelines Published May 2007):
      • Prosthetic heart valve
      • Previous infective endocarditis
      • Congenital heart disease (CHD)

        • Unrepaired cyanotic CHD, including palliative shunts and conduits
        • Completely repaired congenital heart defect with prosthetic material or device whether placed by surgery or by catheter intervention, during the first 6 months after the procedure (endothelialization occurs within 6 months of procedure)
        • Repaired CHD with residual defects at the site or adjacent to the site of a prosthetic patch or adjacent or prosthetic device (which inhibits endothelialization)
      • Cardiac transplant recipients who develop cardiac valvulopathy
    • Patients with any of the above conditions who are scheduled to undergo a dental procedure that is at risk of bleeding should be given antibiotics prior to initiation of procedures.
    • For current guidelines on antibiotic prophylaxis in patients with prosthetic joints who may be at risk of developing infections following dental procedures, the ADA is a good site as well or the American Association of Orthopedic Surgeons Guidelines.

      ADA 2014 Clinical Recommendation
      • In general, for patients with prosthetic joint implants, prophylactic antibiotics are not recommended prior to dental procedures to prevent prosthetic joint infection. For patients with a history of complications associated with their joint replacement surgery who are undergoing dental procedures that include gingival manipulation or mucosal incision, prophylactic antibiotics should only be considered after consultation with the patient and orthopedic surgeon. To assess a patient’s medical status, a complete health history is always recommended when making final decisions regarding the need for antibiotic prophylaxis.
    • The most recent evidence-based guideline was published in the Journal of the American Dental Association (JADA) in 2015. This is accessible on: ​jada.​ada.​org/​article/​S0002-8177(14)00019-1/​fulltext?​nav=​rotatorJanmain.
