    • an abnormal physical examination consistent with congenital syphilis.
    • a serum quantitative nontreponemal serologic titer that is fourfold higher than the mother’s titer;
    • a positive darkfield test (or polymerase chain reaction) of body fluid(s) or lesions
  • Also recommended in neonates who have a normal physical examination and a serum quantitative nontreponemal titer the same or less than fourfold the maternal titer and the:
    • mother was not treated, inadequately treated, or has no documentation of having received treatment.
    • mother was treated with erythromycin or another non-penicillin G regimen.
    • mother received treatment less than 4 weeks before delivery.

ADVERSE EFFECTS

Cardiac arrest has been reported in patients who received high doses infused rapidly. Significant CNS toxicity has been reported in adults with renal failure who developed CS concentrations greater than 10 mcg/mL. Bone marrow depression, granulocytopenia, and hepatitis are rare. Hypersensitivity has not been seen in neonates.

ADMINISTRATION

Intravenous: Administer by IV intermittent infusion over 15 to 60 minutes at a concentration of 100,000 to 500,000 units/mL. Penicillin sodium contains 1.68 mEq sodium/million units and penicillin potassium contains 1.68 mEq potassium/million units and 0.3 mEq sodium/million units.

MONITORING

Follow serum sodium and potassium when using high doses and in patients with renal failure. Observe IV site for signs of extravasation.
