What the FDA labels say
From the Insulin regular (human) (AFREZZA) label · effective 2026-05-30
For patients with type 2 diabetes mellitus, oral antidiabetic treatment dosage modifications may be needed.
For patients with type 2 diabetes mellitus, dosage modifications of concomitant oral antidiabetic treatment may be needed [see Drug Interactions ( 7 )] .
Risk Factors and Mitigation Strategies for Hypoglycemia The risk of hypoglycemia after use of AFREZZA is related to the duration of action of the insulin and, in general, is highest when the glucose lowering effect of the insulin is maximal [See Clinical Pharmacology ( 12.3 )] .
Dosage Modifications for Drug Interactions Dosage modification may be needed when: AFREZZA is used concomitantly with certain drugs that increase and/or decrease the glucose lowering effect [see Drug Interactions ( 7 )].
Clinically Significant Drug Interactions with AFREZZA Antidiabetic agents, Angiotensin-Converting Enzyme Inhibitors, Angiotensin II Receptor Blocking Agents, Disopyramide, Fibrates, Fluoxetine, Monoamine Oxidase Inhibitors, Pentoxifylline, Pramlintide, Salicylates, Somatostatin Analogs (e.g., octreotide), and Sulfonamide Antibiotics Prevention or Management Monitor…
From the Nateglinide label · effective 2025-04-15
Factors which may increase the risk of hypoglycemia include changes in meal pattern (e.g., macronutrient content), changes in level of physical activity, changes to coadministered medication [see Drug Interactions (7)] , and concomitant use with other antidiabetic agents.
Table 2: Clinically Significant Drug Interactions with Nateglinide Drugs That May Increase the Blood-Glucose-Lowering Effect of Nateglinide and Susceptibility to Hypoglycemia Drugs: Nonsteroidal anti-inflammatory drugs (NSAIDs), salicylates, monoamine oxidase inhibitors, non-selective beta-adrenergic-blocking agents, anabolic hormones (e.g., methandrostenolone),…
Drugs and Herbals That May Reduce the Blood-Glucose-Lowering Effect of Nateglinide and Increase Susceptibility to Hyperglycemia Drugs: Thiazides, corticosteroids, thyroid products, sympathomimetics, somatropin, somatostatin analogues (e.g., lanreotide, octreotide), and CYP inducers (e.g., rifampin, phenytoin and St John's Wort).
