In Pennsylvania, Blood Thinner Allergic Reactions
Blood Thinner May Have Caused Allergic Reactions in More Than 50 Dialysis Patients
Vials of the blood thinner heparin may be responsible for allergic reactions in 53 dialysis patients from 12 states.
The suspected batches of heparin were recalled by its manufacturer, Baxter Healthcare Corp. in January, the Associated Press reports, but many vials of the tainted drug were used before the recall was ordered.
The U.S. Centers for Disease Control and Prevention says on its Web site that the nine multi-vial recalled lots were all made at a single plant and that at least another 12 cases are being investigated. Heparin is used to prevent clotting among patients with kidney failure while they're undergoing dialysis.
While none of the reactions has been fatal, the CDC says, the symptoms are uncomfortable and potentially dangerous: "A probable case has been defined as an episode that includes at least two of the following signs and symptoms: 1) generalized or localized sensations of warmth; 2) numbness or tingling of the extremities; 3) difficulty swallowing; 4) shortness of breath, audible wheezing, or chest tightness; 5) low blood pressure/tachycardia; or 6) nausea or vomiting."
The A.P. identifies the states where allergic episodes have been reported as California, Florida, Minnesota, Missouri, New Jersey, New York, North Carolina, North Dakota, Ohio, Pennsylvania, West Virginia and Wisconsin.
"We don't know what the problem is," but heparin remains the leading candidate as the cause, CDC investigator Dr. Priti Patel told the wire service.
