What Happens If You Smoke While on Nicotine Patch?

You should not use the
 nicotine patch (Nicoderm® CQ®) if you continue to smoke, chew tobacco, or use any other nicotine-containing products, including other nicotine replacement therapies. 
 
What happens if you smoke while on the nicotine patch? The nicotine from the nicotine patch will remain in your blood for several hours after you remove the patch. If you smoke (even if you are not wearing the nicotine patch), you could increase your risk for a nicotine overdose. This could cause symptoms such as:
 
  • Nausea and vomiting
  • Abdominal (stomach) pain
  • Respiratory failure
  • Seizures.
 
It is also important to not use the nicotine patch with any other nicotine-containing product, such as nicotine gum or lozenges, unless your healthcare provider tells you otherwise.
