Hi, thanks for using healthcare magic
of the eyes is not a known side effect of the nicotine patch
and has only been reported in 0.02% of persons using zyban
according to a study conducted.
Other causes of red eyes would be: dry eyes, infection, allergies, blood, trauma
If is continues or is associated with symptoms such as decreased vision, light sensitivity, pain, discharge- you may want to consider visiting your doctor for treatment.
I hope this helps and good luck with the smoking
