The U.S. Food and Drug Administration wants some stronger warnings to come with the anti-smoking drug Chantix. The FDA says after an analysis of reports of suicidal thoughts and behavior potentially linked to the medication, it was calling for stronger label warnings.

Regulators say the drug is effective but that patients should talk to their doctors about this new safety information.

According to the manufacturer, Chantix has been prescribed to about four million people in the United States.
