A person who exercises while wearing a nicotine patch may be at risk for increased absorption of nicotine. Some patients may develop nicotine toxicity as a result.
Patient selection: use of a transdermal nicotine patch during exercise
The increase in circulation due to exercise would be expected to increase nicotine absorption compared to rest.
Risk factors for increased nicotine levels:
(1) extreme or prolonged exertion
(2) multiple patches
(3) increased environmental temperature
(4) occlusion over patch
(5) abrasion over patch
(6) other sources of nicotine (smoking, nicotine gum)
