DESSERT ITEMS RECALLED OVER ALLERGY CONCERNS
The drug's recall, which was first issued in July, is due to the presence of a nitrosamine called N-nitroso-varenicline, which has been found to be at or above the Food and Drug Administration's interim acceptable intake limit.
Most consumers are exposed to nitrosamines to some degree, with the chemical being common in water and foods, including cured and grilled meats, dairy products and vegetables.
"Long-term ingestion of N-nitroso-varenicline may be associated with a theoretical potential increased cancer risk in humans, but there is no immediate risk to patients taking this medication," Pfizer said in its recall notice.
