A preliminary investigation showed there was no trace of the sedative zopiclone in the drug maker's diuretic furosemide, Teva said in a statement.
French police said on June 9 they were treating the man's death as "suspicious" after he was given medicine that may have been wrongly labeled as a diuretic drug.
France's pharmaceutical watchdog ANSM had asked pharmacies to take 190,000 boxes of Teva's drug off their shelves just two days before the man died, saying they may contain zopiclone.
"The results of the investigation clear Teva of all suspicion of failure in its operations," Teva Chief Executive Jeremy Levin said.
Teva, the world's No.1 generic drug maker, said ANSM's decision to recall the drugs had been the right one, even though it proved unnecessary in retrospect.
