Which adverse effect is associated with fospropofol but not typically seen with propofol?

• A. Genital and Anal Burning
• B. Respiratory Depression
• C. Hypotension
• D. Sedation

Answer: (A)

Fospropofol is a water-soluble prodrug that is hydrolyzed to propofol and byproducts such as formaldehyde and phosphate. The distinctive adverse effect with this prodrug is a burning sensation in the genital and perineal area (often with pruritus) due to local irritation from the prodrug/byproducts as they’re released during conversion. This localized burning is not typically seen with propofol itself, which is administered directly as the active drug and doesn’t produce those irritant byproducts. Other effects like respiratory depression, hypotension, and sedation can occur with both agents, so they aren’t unique to the prodrug.
