(CNN) -- Fifteen patients have been hospitalized in Texas after getting calcium gluconate injections, according to the Food and Drug Administration. The FDA has issued a national voluntary now for all sterile-use products produced by Specialty Compounding LLC, based in Cedar Park, Texas. What is a compounding facility? The people hospitalized have a bacterial infection in their blood, and doctors think it might have come from the injection. A culture taken from a sample of this injection shows bacterial growth that is consistent with a Rhodococcus species (PDF) of bacteria, according to the FDA. "The FDA believes that use of these products would create an unacceptable risk for patients," said Dr. Janet Woodcock, the FDA's director for drug evaluation and research. "Giving a patient a contaminated injectable drug could result in a life-threatening infection."
