Internal Medicine Specialist,  's  Response
Hello,

Chantix (Varenicline) -a nicotinic acetylcholine receptor partial agonist reduces the feelings of craving and withdrawal caused by smoking cessation.
You need to quit smoking, if you are having attacks of severe asthma requiring ventilatory support.
Nausea and vomiting may be troublesome for some people with Varenicline.
Lowering the dosage may be an option.

Hope I have answered your query.
Let me know if I can assist you further.

Regards,
