Primary Issue
The response confuses LEUKERAN, which the label identifies as oral chlorambucil tablets, with 5-fluorouracil injection and repeatedly describes an unsupported vial formulation.
Suggested Improvement
Correct the product identity and dosage form before discussing cost. Limit label-based conclusions to the supplied information: LEUKERAN is chlorambucil 2 mg oral tablets supplied in bottles of 25 and stored refrigerated at 2° to 8°C. Pricing, insurance, pharmacy, and availability claims should be identified as outside the supplied label rather than presented as label-supported facts.
