Pfizer's anti-smoking drug: India Versus US

Anti-smoking drug varenicline commercially available as Champix in India, has been launched by Pfizer Ltd., an Indian unit of US pharmaceutical giant. This particular drug branded Chantix in US has been warned by US FDA regulators as the drug causes “changes in behavior, agitation, depressed mood, suicidal thoughts, attempted and completed suicide”. The FDA continues its review of the adverse event reports, and concludes that there may be an association between Chantix and serious mood and behavior symptoms.”

I personally feel that Indian regulators must ask Pfizer to display safety information prominently on its label.
