I am using fluticasone propionate nasal spray for last 4 weeks on ent prescription cuz i am suffering from maxillary sinitius. i have noticed significant hair fall from head and other parts of body. is this steroidal spray the reason behind this ??

I find the chance it might an exceedingly small possibility. The concentration of the spray provides a minimal amount of steroid to the nasal tissues that metabolize it quickly. Very tiny amounts would be left to enter your bloodstream and effect anything else. Your body makes a biosimilar stress hormone every day. I would look to other potential causes and not assume this is it.
