Is it OK to smoke on Coumadin (warfarin)?
Can you still smoke when taking Coumadin? Does smoking hinder Coumadin from working in your body? My husband is on Coumadin, and started smoking again.
Dr. Gourmet Says...
I often have patients ask me if they can smoke. My reply is usually pretty sarcastic: "You can do anything you want, but smoking is going to kill you."
OK, sarcasm aside, the answer to your question is that we don't know for sure. There are conflicting reports in the literature, with some saying that smoking more will decrease the INR. There are isolated case reports as well of this but so far no definitive evidence. Other reports have shown no difference.
There's no reason for your husband to take the risk with his health in general and especially when using a medication like Coumadin® (warfarin). He should talk with his doctor about quitting. There are a lot of ways to work at quitting smoking including very good classes and support groups. His physician can also talk to him about medications that might help.
Quitting smoking is one of the most important things you can do for yourself. I send you and your husband every good wish at success.
