66 drugs at risk of new, worsened shortages after tornado hit Pfizer plant

Pfizer told hospital buyers that 66 of its products "may experience continued or new supply disruptions in the near term" because less than three months' worth of supply is in the market.

In a letter dated July 21 — two days after a tornado struck one of its largest drug manufacturing plants — Pfizer said the "three-month inventory threshold represents an abundance of caution based on the information available today and is not reflective of any estimates of production restart."
