FDA says Germany recalls blood-thinner heparin

By Kim Dixon

WASHINGTON (Reuters) - Germany has recalled supplies of the blood thinner heparin following reports of severe reactions, expanding a withdrawal of the drug linked to 19 U.S. deaths, the Food and Drug Administration said on Thursday.

The recall brings into question the safety of European supplies of the drug, which become the target of a U.S. investigation after a spike in fatalities and severe reactions in some patients taking heparin sold by Baxter International Inc.

"What is significant about the German recall is that the heparin active ingredient in their product was not obtained from SPL," or Scientific Protein Labs, Baxter's supplier, FDA Deputy Commissioner Janet Woodcock said.

"We're concerned about worldwide, this contaminant, in heparin and making sure it is safe, (and) out of the heparin supply," Woodcock said.

German authorities do not expect a shortage of the drug, FDA said.

The FDA began probing Baxter's heparin several weeks ago after it was linked with to four deaths and hundreds of severe reactions, such as breathing problems and rapid drops in blood pressure. On Wednesday it said it identified a contaminant that may be linked with the drug's problems.

Some 19 fatalities have now been associated with use of the drug in the United States, the FDA said on Wednesday. However, all the deaths have not been linked to a specific drug maker.

The other major U.S. heparin supplier, APP Pharmaceuticals Inc, has ramped up production to avoid a drug shortage. Tests on APP's heparin have not found any contamination, Woodcock said on Wednesday.
