Is Vitamin D Safe with Fluticasone?
Free · No account · based on published sources including NIH ODS, FDA drug labels, and peer-reviewed literature
Ensure adequate vitamin D intake (at least 600–1000 IU/day) if using inhaled fluticasone long-term, and up to 2000 IU/day if also using systemic corticosteroids. Discuss bone health monitoring with your provider.
Why this interaction occurs
Long-term inhaled corticosteroid use, including fluticasone, can impair calcium absorption and suppress vitamin D metabolism, contributing to reduced bone mineral density over time. Systemic absorption of inhaled fluticasone, though low, may be sufficient with high doses and prolonged use to affect bone metabolism. Supplementing vitamin D and calcium is an evidence-based strategy to mitigate corticosteroid-associated osteoporosis risk.
