Does fluticasone / q var immunocompromise respiratory epithelium? i'm in healthcare & i garden. increased risk of viral, bacterial, or fungal infx?

Minimal risk at most: If anything, underlying allergies and/or asthma will leave you at greater risk to develop infections. The anti-inflammatory treatment your referenced can theoretically reduce the inflammatory response, but they intend to do just that. Patients with allergic conditions have high inflammation levels that benefit from such treatment.
