In the article by Gloria Lee Wilder that appears in the September/October issue of JIN [2003;26(5):311-318], there is an error. On page 315, item 4, Inadequate Reference Materials incorrectly states that benzathine penicillin as a suspension should not be administered IM. The statement should read: "References tended to summarize all forms of penicillin in one section and did not clearly specify benzathine penicillin as a suspension that should be administered only IM."
