Retired, cheap sob, ophthalmologist wants us to order and dispense Fluorouracil Injection 2.5gm/50ml(50mg/ml) for himself or wife for topical use not injection. I can find nothing that recommends topical use of this product. Yes, he ordered it but not sure that means a thing in this case if something goes south. He only wants it because its the very cheapest way to go. Personally uncomfortable with this. anyone have experience with using this topically? would you fill this?
