What best describes the systemic safety profile of nasal corticosteroids?

• A. There is a lot of variation among agents within the class.
• B. Some systemic adverse effects have been reported.
• C. There are no significant systemic effects with these.
• D. They are associated with frequent nasal bleeding.

Answer: (C)

Intranasal corticosteroids are designed to act mainly on the nasal mucosa, with very little entering the bloodstream. Because of limited systemic absorption and rapid metabolism, systemic adverse effects are not expected to be significant when used at approved doses. In other words, their safety profile is favorable systemically, even though you may see local issues like nasal irritation or occasional nosebleeds. While some systemic presence can occur at very high doses, it typically doesn’t translate into meaningful systemic toxicity in normal use.
