The U.S. Food and Drug Administration (FDA) has announced a voluntary recall of Chantix, also known as varenicline, a medication widely prescribed to help people quit smoking. The decision comes after routine testing revealed elevated levels of nitrosamines in certain batches of the drug.
Nitrosamines are chemical compounds that occur naturally in some foods and water but can become harmful when found at higher levels in medications. Long-term exposure to elevated amounts has been linked to an increased risk of cancer, prompting global health authorities to take them seriously.
