Public Citizen Wants Prandin, Plavix Label Changes
Public Citizen says that FDA should require changes to the labels for repaglinide-containing medications (Novo Nordisk’s Prandin and Prandimet) and clopidogrel (Bristol-Myers Squibb’s Plavix) to include information on what it says is a serious drug-drug interaction that could result in severe hypoglycemia. The advocacy group’s petition also says that the labels for both drugs should include a Contraindication to using the two drugs together due to the interaction.
Studies conducted in Finland and Japan established the dangerous interaction, Public Citizen says. It notes that on 7/31/15, Health Canada issued an alert to healthcare professionals warning about the risk of dangerously low blood sugar levels when the two drugs are taken together. It also required that Canadian product labels for each drug be updated to reflect information about the interactions and to include a contraindication warning against taking the two drugs together under any circumstances.
“FDA has not taken similar actions,” the petition says. “Regarding the U.S. product labels, only the label for clopidogrel includes information on the interaction with repaglinide, within the Drug Interactions section. Inexplicably, FDA has not required the same information to be inserted into the label for repaglinide. Moreover, there is no Contraindication to the use of the two drugs together in either label, as was put in place in Canada.”
