Inhaled insulin vs injections: What’s the difference and who is it for?

Inhaled insulin differs from traditional insulin injections, as it is administered via a specialised inhaler that delivers insulin powder directly into the lungs. This allows for rapid absorption into the bloodstream, providing quick relief from post-meal blood sugar spikes. However, inhaled insulin is not suitable for individuals with certain lung conditions or those who smoke, as it may worsen their breathing problems.

It also has a shorter duration of action compared to long-acting insulin injections, making it a complementary rather than a full replacement for injectable insulin. Inhaled insulin is primarily used before meals and is not recommended for children, pregnant women, or those with unstable lung disease. Potential side effects include cough, throat irritation, and dry chest sensation.

Further research is needed to fully understand the long-term safety of this delivery method for insulin.
