The FDA has issued a serious alert regarding faulty glucose monitor sensors, which may be linked to at least seven deaths and over 700 serious injuries. Patients using Abbott’s FreeStyle Libre systems are particularly at risk, with reports indicating malfunctioning devices can lead to dangerously incorrect readings. Abbott has responded by issuing an urgent message to patients and recalling millions of devices, urging users to immediately discontinue use if they have these products. The ongoing investigation highlights the critical safety concerns surrounding diabetes management technologies.
