If you use Chantix to help you quit smoking, the government wants you to read the warning on the label. And just in case you miss it, the FDA is asking the manufacturer to make that warning bigger and bolder.
Chantix was approved in May of 2006 as a smoking cessation drug and it works by blocking some of the effects of nicotine on the brain. But the Federal Drug Administration is investigating more and more reports of depression, mood changes, and even suicidal thoughts which may be linked to the drug.
The FDA says Chantix does help many smokers kick the habit, but physicians should closely monitor them for unusual behavior while taking this drug,
Chantix is also known by its generic name Varenicline.
