Abstract
Hidden sources of exposure to penicillin may assume great importance as the use of this antibiotic continues to increase. Possible sources include milk and dairy products, mold in household articles and food, contaminated syringes, vaccines containing penicillin, and penicillin dust in the air. Statistical evidence indicates that only a few absolute indications for the use of penicillin remain.
If a patient's history strongly suggests sensitivity to penicillin and the physician is unable to devote the time to perform the procedures necessary to protect the patient's safety, it may be wise to refer him to someone who makes these tests routinely. Measures for treating anaphylactoid and other reactions to penicillin are outlined.
