Nicotine lozenges, one form of nicotine replacement therapy (NRT), are used to help people quit smoking. According to the American Heart Association, the consistent and safe use of NRT doubles a smoker's chances of successfully quitting. When teamed with behavioral modification and support programs, nicotine lozenges increase the odds of quitting even further. All NRT methods, including lozenges, work by relieving the withdrawal symptoms that often cause smokers to return to cigarettes. However, like any drug, nicotine lozenges have side effects that should be monitored to ensure safety.
Abnormal Mouth Sensations
According to the Sloan-Kettering Memorial Cancer Center, a sudden burst of warmth or mouth tingling is expected with the use of nicotine lozenges, and no cause for alarm. However, severe mouth pain, another possible lozenge side effect, could indicate a serious problem.
Sore Throat and Indigestion
Sore throat and heartburn or indigestion may occur with nicotine lozenge use. The National Institutes for Health suggests contacting your health care provider if these symptoms are severe and persistent.
Heart Symptoms
Because nicotine lozenges contain nicotine, they can still have a stimulating effect on the cardiovascular system. The Sloan-Kettering Cancer Center explains that irregular heartbeat, heart palpitations, or rapid heart rate are all cause for concern and should result in an immediate call to your health care provider.
Nausea and Dizziness
Use of nicotine lozenges may cause nausea and dizziness in some people. If the symptoms persist, it's best to contact a health care professional.
