Will azmacort (triamcinolone) cause mucous?

Yes as asthma improv: As asthma improves and the airways dilate and become less inflamed, mucous and bronchial secretions can be more easily coughed out. Continued use after that maintains breathing capacity. Chest congestion will clear usually over a period of 3 to 6 weeks. It is best to use the medication 3 to 4 times/day until secretions clear and reduce dose thereafter to maintain breathing capacity.
