UNASSIGNED: Urine drug screens (UDSs) are used to identify the presence of certain medications. One limitation of UDSs is the potential for false-positive results caused by cross-reactivity with other substances. @entity889 have an extensive list of cross-reacting medications. The literature contains reports of false-positive @entity4944 UDSs with multiple antidepressants and antipsychotics. We present 2 cases of presumed false-positive UDSs for @entity889 after ingestion of @entity1770 . Case 1 was a 16-month-old @entity1 who accidently ingested 15 to 45 mg of @entity1770 . She was lethargic and ataxic at home with 1 episode of @entity391 containing no identifiable tablets. She remained sluggish with periods of @entity146 and was admitted for observation. UDS on 2 consecutive days came back positive for @entity889 . Case 2 was of a 20-month-old @entity1 who was brought into the hospital after accidental ingestion of an unknown quantity of her father's medications which included @entity1770 . UDS on the first day of admission came back positive only for @entity889 . Confirmatory testing with gas chromatography-mass spectrometry (GC-MS) on the blood and urine samples were also performed for both @entity1 on presentation to detect @entity889 and were subsequently negative. Both @entity1 returned to baseline and were discharged from the hospital. To our knowledge, these cases represent the first reports of false-positive @entity4944 urine drug tests with @entity1770 . In both cases, @entity1770 was the drug with the highest likelihood of causing the positive @entity4944 screen. The implications of these false-positives include the possibility of unnecessary treatment and monitoring of @entity1 .
