The couple, who both live in France, were convicted of using confidential patient information in Daoud's novel "The Scar" and of violating personal integrity, the newspaper El Khabar reports.
Both were sentenced to five years in prison.
An Algerian woman has accused Daoud of using details from her life in "The Scar". She had entrusted the information to Daoud's wife, who was treating her as a patient.
Daoud has denied the accusations.
He wrote "The Scar" in exile in France and received the Goncourt Prize in 2024.
He was sentenced in Algeria in the spring to three years in prison in another case involving the novel.
