Patient discussion about patch

Q. nicotine patch does anyone know if you can use the patch for smokeless tobacco users,that dont smoke,and how well does it work,what are the side effects,i"ve been using smokeless tobacco for 24 years and would like to stop,tried going cold turkey,but it didnt work,my dr. said i should try the patch,but couldnt tell me if it would work or not.

A. There is really no reason you couldn't try the patch. The problem would be with what dose to start. Usually if people smoke more than 10 cigarettes a day they start with the 21mg but I am not sure how smokeless tobacco relates to cigarettes. Your best bet may be to try the gum as you chew it and then place it between you cheek and gum for a while, similar to dip.
