Several companies manufacture Methylprednisolone Acetate, so patients who are unsure whether they received the contaminated doses are urged to call their health care provider.

The lots of medication that were used on infected patients are:

  • Methylprednisolone Acetate (PF) 80 mg/ml Injection, Lot #05212012@68, BUD 11/17/2012
  • Methylprednisolone Acetate (PF) 80 mg/ml Injection, Lot #06292012@26, BUD 12/26/2012
  • Methylprednisolone Acetate (PF) 80 mg/ml Injection, Lot #08102012@51, BUD 2/6/2013

Infected patients have shown symptoms approximately one to four weeks following their injection. The symptoms include fever, new or worsening headache, nausea, and/or new symptoms consistent with a stroke. Some of the patients’ symptoms were very mild.
