This is the first English-language vampire film to show a vampire with visible fangs.
American International Pictures released this film to many drive-in theaters on a double bill with I Was a Teenage Frankenstein (1957) with the tag line: "Warning! Can You Take It? Fiendish! Frenzied! Frightening! It Will Haunt You For Days Afterwards[sic]!"
The "Blood of Dracula" poster motif is based on a Chester Collum illustration from "Adam" magazine Vol. 1 No.10 1957. It reappears further altered on the cover of "Tales of Voodoo", May 1974.
Despite its title and the reference in it to the Carpathian Mountains in Romania, this film has absolutely nothing to do with either Dracula or his blood.
