Some medications cannot be taken at the same time as Chantix (varenicline). This is not true for all medications, however. Before taking Chantix, tell your doctor all prescription medications, over-the-counter medications, vitamins and herbal supplements you are taking. Your doctor will assess your medications and supplements, and determine if you can safely take Chantix.
The primary drug that interacts with Chantix (varenicline) is nicotine; tell your doctor if you are taking any medications that contain nicotine, including any to help you quit smoking.
