Tim Russ (T'Kar) makes his second Star Trek appearance in this episode. He would later play Tuvok on Voyager.
   
John Glover (Verad) currently plays Lionel Luther in the series Smallville. He also played the Devil in the short lived cult series Brimstone.
   
Cirroc Lofton (Jake) doesn't appear in this episode.
   
Michael Westmore used a vibrating pencil he found at Toys "R" Us to make the Dax symbiont move around during the transfer sequence.
   
The pouch that the symbiont crawls in and out of is a simple latex sheet that is glued to the actor's stomach.
   
Glenn Neufeld and David Takemura created the plasma storm by pouring liquid nitrogen onto flats of black velvet, producing a swirling pattern. Since the nitrogen dissipates rapidly when exposed to air, Takemura recalls that "We shot it at the highest speed we could on the motion control rigs at Image G."
   
Megan Gallagher would return in the fourth season for "Little Green Men".
   
Terry Farrell on Dax in "Invasive Procedures":
"I approached [the scenes in the Infirmary] with the idea that Jadzia is scared, that she feels helpless. She cares very deeply for everyone on the station and is afraid for them. That's why she's willing to say, 'Fine, I'll give my life for everybody and you can have Dax.' But that had been while the strength of Dax was inside of her, telling her that everything was going to be okay. Once the worm is gone, she's only twenty-eight years old, and it's like, 'Wait, I haven't lived that munch life yet.'"
   
The episode marked the first use of Bashir's surgery, a new redress of a swing set that is attached to the Infirmary. The swing set also found use as the station's schoolroom and security.
