Yes: This may be an allergic reaction to varenicline (compound in chantix). I would encourage you to tell your prescribing provider asap. If my patients develop hives on a new medication, i advise them to stop the medication. If you have swelling of your mouth, tongue, lips. Throat or face or any problems with breathing this could be life threatening & would require emergency medical treatment.
