In response to your concerns regarding vomiting
while using Chantix
, one of the most common side effect of Chantix is nausea
and vomiting. Chantix causes the GI upset and not the composition of the emesis
also causes nausea and vomiting. If there is any chance for you to be pregnant, you will need to see your OB/GYN doctor. You can stop the Chantix and then restart again after your OB/GYN doctor says that s/he is fine with that medication.
If you are not pregnant, then in all liklihood, the Chantix is causing the GI upset. Most people find that this subsides after about 2 weeks. If the nausea & vomiting are severe, you will need to stop the medication.
The "white foam" composition of your emesis is not a particular worry.
