Each blue cartridge of Afrezza powder is equal to 4 units of injectable insulin. Each green cartridge is equal to 8 units of injectable insulin. If your dose is more than 8 units, you will need to use more than one cartridge. Always use the least number of cartridges possible to get your correct dose. For example, if your dose is 12 units, use one 4-unit cartridge and one 8-unit cartridge to equal 12 units. For a dose of 16 units, use two 8-unit cartridges. Follow the dosing chart provided with this medicine to learn about combining cartridges to get the correct dose.
Why it matters : Latest BTS/SIGN guidance on the treatment of asthma recommends that patients should be maintained at the lowest possible dose of inhaled corticosteroid. Reduction in inhaled corticosteroid dose should be slow as patients deteriorate at different rates. Reductions should be considered every three months, decreasing the dose by approximately 25–50% each time. 'High-dose' inhaled corticosteroids are listed at step 4 of the guidelines. The latest guidance for treatment of COPD now recommends use of another treatment in preference to inhaled corticosteroids. There is some evidence that inhaled corticosteroids increases the risk of pneumonia. This risk appears to increase with dose.
