TABLETS WERE NOTED in the vomitus of a 20-month-old girl. Unwitnessed, she had ingested a quantity of her grandmother's medication from a prescription container labeled "Procardia XL, 30 mg" (Pfizer Inc, New York, NY). Examination of the vomitus revealed 9 tablets and some activated charcoal (Figure 1). Concern arose because the tablets did not match the appearance of Procardia XL tablets (Figure 2). A Procardia XL tablet was obtained from an inpatient pharmacy and rinsed under water (Figure 3). Figure 4 is a schematic drawing of the nifedipine Gastrointestinal Therapeutic System (GITS).
