A Rare Reaction: When an Inhaler Triggers Sweet Syndrome

A routine change in treatment for Chronic Obstructive Pulmonary Disease led to an unexpected medical case when a 55-year-old woman developed painful red skin lesions and a mild fever just 48 hours after starting a new inhaler.

Initially, the symptoms appeared to be a common skin reaction. However, further evaluation confirmed a diagnosis of Sweet syndrome, a rare inflammatory condition characterized by sudden, painful red plaques and fever.

The patient had no recent infections or lifestyle changes, making the newly prescribed inhaler the most likely trigger. While drug-induced Sweet syndrome is known, this case is unusual because it may be linked to an inhaled medication—something rarely reported.

After discontinuing the inhaler and starting corticosteroid treatment, the patient showed rapid improvement within two days, with symptoms resolving quickly.

This case highlights the importance of monitoring new medications, even those considered safe and commonly used. It also underscores the need for timely diagnosis when symptoms do not match typical patterns.

Conclusion:
Even routine treatments can sometimes cause rare reactions. Early recognition and proper medical care are essential for effective recovery.
