Portugal's doctors slam generic rule for glucose monitors as unsafe

The Portuguese Medical Association (Ordem dos Médicos, OM) has strongly opposed a new rule requiring generic prescriptions for continuous glucose monitoring (CGM) sensors. The organisation warns that treating these devices like interchangeable generic drugs risks patient safety and undermines tailored diabetes care. Other medical groups, including the Portuguese Diabetes Society, have also condemned the decision by Infarmed, the national health authority. OM’s criticism came after Infarmed introduced a measure mandating generic prescribing for CGM systems. The association described its position as one of 'deep concern and strong disagreement,' arguing that such a policy fails to recognise the unique functions of each sensor. Physicians have stressed that, unlike generic medications, CGM devices are not interchangeable due to differences in accuracy, features, and compatibility with insulin pumps.

Carlos Cortes, OM’s president, highlighted that efficiency in public health spending should not come from arbitrary decisions. He called for a more considered approach to resource management. Manuel Carlos Lemos, head of OM’s College of Endocrinology and Nutrition, echoed these concerns, warning that the policy threatens personalised treatment plans for diabetes patients. The Portuguese Diabetes Society reinforced this stance, stating that Infarmed’s decision reveals a fundamental misunderstanding of CGM technology. According to the society, the safety and effectiveness of diabetes management rely on the specific characteristics of each system. Both organisations are now urging the immediate reversal of the measure and demanding open discussions with medical professionals and patient representatives.

OM and the Portuguese Diabetes Society have made clear that generic prescribing for CGM sensors could disrupt patient care. They insist that Infarmed’s policy must be reconsidered to ensure both safety and the continued personalisation of diabetes treatment. The call for dialogue remains a key demand as medical groups seek a resolution.
