Hi my DH is wanting to give Champix a go to quit smoking, a few guys he works with are doing it and they havent had a cigarette for weeks. My worry is that we are TTC and if he starts taking the tabs is there any risk of birth defects. He hasnt been to the Dr yet as he works away but i'm a little worried that if he starts taking it before we conceive there could be problems, waiting for him to start taking it and then how long for I dont know? but i'm 40 and dont want to keep leaving my run too late. Just wondering if anyone has any experience or knowledge on the subject. TIA.
