What Is Varenicline 1mg?
Varenicline is a prescription medication approved by the FDA to help adults stop smoking. It is a partial agonist at nicotinic acetylcholine receptors, which means it both eases cravings and withdrawal symptoms and blunts the rewarding effects of nicotine if you do smoke. Varenicline is sold under the brand name Chantix and is taken as an oral tablet, typically over a 12-week course that may be extended. It is most effective when combined with counseling or a structured quit-smoking program.
