Please read this first. This guide is a companion to your medical team, not a replacement, and it is not medical advice. Everything here is tied to published research. If something you expected is not here, it almost always means we have not mapped a source for it yet, not that it is unknown to medicine. primary ciliary dyskinesia is an early, growing map, so it will look incomplete on purpose: we would rather show less and have every line be something you can check than fill the page with claims we cannot stand behind. For anything about your own situation, your clinicians hold the full picture. How this guide is built and why.

What's primary ciliary dyskinesia?

Primary ciliary dyskinesia is a rare inherited disorder in which the tiny hair-like cilia that clear the airways do not move properly, so mucus and bacteria are not cleared from the respiratory tract.

Treatment and management

What the research describes, not a recommendation. Treatment decisions belong with your clinician.

This covers treatments that appear in the published research mapped here. Investigational and experimental therapies are not included, so their absence is a boundary of this map, not a sign they do not exist.

azithromycin

Long-term macrolide antibiotics such as azithromycin may reduce flare-ups in people with frequent bronchiectasis exacerbations.

Used to help with: Bronchiectasis.

Limited evidenceSource: PMID:40293759
The source text this rests on
“Individuals with 3 or more exacerbations of bronchiectasis annually may benefit from long-term inhaled antibiotics (eg, colistin, gentamicin) or daily oral macrolides (eg, azithromycin).”
