What Are the Dosages of Insulin Inhaled?
Adult dosage
Orally inhaled powder
- Available as single-use cartridges
- 4 units/cartridge
- 8 units/cartridge
- 12 units/cartridge
Diabetes Mellitus (Types 1 and 2)
Adult dosage
- Dosing must be individualized
- Starting mealtime dose
- Insulin naïve: 4 units at each meal initially
- Converting from SC mealtime (prandial) insulin: Determine the appropriate inhaled insulin dose for each meal by converting from the injected dose (see Mealtime dose conversion)
- Using SC premixed insulin: Estimate the mealtime injected dose by dividing half of the total daily injected premixed insulin dose equally among the 3 meals of the day; convert each estimated injected mealtime dose to an appropriate inhaled insulin dose (see Mealtime dose conversion); administer half of the total daily injected premixed dose as an injected basal insulin dose
- Mealtime dose conversion
- Dosage adjustment may be needed when switching from insulin to inhaled insulin
- Up to 4 units SC = 4 units inhaled
- 5-8 units SC = 8 units inhaled
- 9-12 units SC = 12 units inhaled
- 13-16 units SC = 16 units inhaled
- 17-20 units SC = 20 units inhaled
- 21-24 units SC = 24 units inhaled
Dosage Considerations – Should be Given as Follows:
- See “Dosages”

What Are Warnings and Precautions for Insulin Inhaled?
Contraindications
- During episodes of hypoglycemia
- Chronic lung disease (eg, asthma, COPD), because of the risk of acute bronchospasm
- Hypersensitivity to regular human insulin or any inhaled insulin excipients
Effects of drug abuse
- None
Short-Term Effects
- See “What Are Side Effects Associated with Using Insulin Inhaled?”
Long-Term Effects
- See “What Are Side Effects Associated with Using Insulin Inhaled?”
Cautions
- Acute bronchospasm observed in patients with asthma and COPD; before initiating, perform spirometry (FEV1) in all patients; do not use in patients with chronic lung disease
- Change insulin regimen under close medical supervision and increase the frequency of blood glucose monitoring
- Hypoglycemia reported and may be life-threatening; increased frequency of glucose monitoring with changes to insulin dosage, coadministered glucose-lowering medications, meal pattern, and physical activity; and in patients with renal or hepatic impairment and hypoglycemia unawareness
- Assess pulmonary function (eg, spirometry) before initiating, after 6 months of therapy, and annually, even in the absence of pulmonary symptoms
- Two cases (2 in 2750 patient-years exposure) of lung cancer were reported during clinical trials, both were in patients with a history of heavy smoking; 2 additional cases of lung cancer (squamous cell and lung blastoma) occurred in nonsmokers were reported by investigators after clinical trial completion; in patients with active lung cancer, a prior history of lung cancer, or those at risk for lung cancer, consider whether the benefits of use outweigh this potential risk
- More patients using inhaled insulin (0.43%) experienced diabetic ketoacidosis in clinical trials compared with comparators (0.14%); monitor and change to an alternate route of insulin delivery, if indicated
- Hypersensitivity reactions, including severe, life-threatening, generalized allergy, and anaphylaxis can occur with insulin products
- Hypokalemia may occur, including life-threatening low serum levels; monitor potassium levels in patients at risk
- Monitor for fluid retention and heart failure with concomitant use of thiazolidinediones; consider dosage reduction or discontinuation if heart failure occurs
Pregnancy and Lactation
- Limited available data on pregnant women are insufficient to determine drug-associated risks for adverse developmental outcomes; available information from published studies with human insulin use during pregnancy has not reported a clear association between human insulin and adverse developmental outcomes; there are risks to mother and fetus associated with poorly controlled diabetes in pregnancy; in animal reproduction studies, there were no adverse developmental outcomes with subcutaneous administration of carrier particles (vehicle without insulin) to pregnant rats during organogenesis at doses 14-21 times the maximum recommended daily dose
- Poorly controlled diabetes in pregnancy increases the maternal risk for diabetic ketoacidosis, pre-eclampsia, spontaneous abortions, preterm delivery, stillbirth, and delivery complications; poorly controlled diabetes increases the fetal risk for major birth defects, stillbirth, and macrosomia-related morbidity
- Lactation
- There are no data on the presence in human milk, its effects on the breastfed infant, or milk production; one small published study reported that exogenous insulin was present in human milk; no adverse effects in infants were noted; carrier particles are present in rat milk; potential adverse effects that are related to inhalational administration are unlikely to be associated with potential exposure through breast milk; the developmental and health benefits of breastfeeding should be considered along with mother’s clinical need for therapy and any potential adverse effects on the breastfed infant or from an underlying maternal condition
