It has been said that a drug is usually out of your system within 5 to 6 half lives. Therefore, within 5-6 days most of the <a href="https://rxchat.com/Drugs/Chantix/" target="_blank">Chantix</a> would most likely be out of your system. Since you've only been off of it for 3-4 days then there is probably enough left in your system to keep your from having to start all over with the (0.5 mg) dose. I think taking the next dose up from that would be sufficient, however I am not a doctor so that is just my opinion based on the research that I've done. <br/> <br/> You can learn more about this drug on the page for <a href="https://rxchat.com/wiki/Chantix/" target="_blank" rel="nofollow">Chantix Details</a> <br/> <br/> I hope this reply helps in some way!
