can cause redness
, itching, muscle pain
and tenderness at the site of application; but as far as I know, it doesn't cause loss of muscle bulk. If you feel that it is due to the patch, try changing the site of application frequently. The best thing would to quit the patch as well as you have been off smoking
for 7 months. Nicotine replacement therapy
is meant to be used only for a short term. So gradually reduce the dose of the patch as far as possible and then quit. You will find it is much easier than quitting smoking.
