Information on overdosage with Floxin is limited. One incident of accidental overdosage has been
reported. In this case, an adult female received 3 grams of Floxin intravenously over 45 minutes. A
blood sample obtained 15 minutes after the completion of the infusion revealed an Floxin level of
39.3 µg/mL. In 7 h, the level had fallen to 16.2 µg/mL, and by 24 h to 2.7 µg/mL. During the infusion,
the patient developed drowsiness, nausea, dizziness, hot and cold flushes, subjective facial swelling
and numbness, slurring of speech, and mild to moderate disorientation. All complaints except the
dizziness subsided within 1 h after discontinuation of the infusion. The dizziness, most bothersome
while standing, resolved in approximately 9 h. Laboratory testing reportedly revealed no clinically
