The short version
Just 2 companies supply this market — thin enough that a single exit would be felt immediately. The price has held steady around $9.28 per mL over the past year. It is in shortage right now — FDA lists the reason as “delay in shipping of the drug”. A Class II recall hit this product in the past year (Apotex Corp.). Put together: this is a fragile supply — if anything else goes wrong, there is very little slack to absorb it.
