Medical opinions differ about whether there is a greater risk for people with heart disease taking Chantix. There have been multiple studies, but the patients and results have varied. Hopefully, future studies will clearly answer this question. Until we are sure, the FDA advises that there may be a small, increased risk of certain cardiovascular adverse events in patients who have cardiovascular disease. You should contact your healthcare professional before using, and if you experience new or worsening symptoms of cardiovascular disease, such as shortness of breath or trouble breathing, new or worsening chest pain, and new or worse pain in legs when walking, after taking Chantix.
