What are the warnings or precautions associated with the use of nicotine replacement therapy (NRT) in patients with cardiovascular disease?

Nicotine replacement therapy (NRT) carries specific warnings and precautions, particularly in patients with cardiovascular disease. Using NRT cautiously in these patients is essential due to the potential for increased heart rate and blood pressure. Nicotine can stimulate the release of catecholamines, leading to cardiovascular effects that are concerning, especially for individuals with pre-existing conditions like hypertension or coronary artery disease.

For patients with cardiovascular disease, it is crucial to evaluate the risks and benefits of NRT carefully. This ensures that any treatment plan does not exacerbate their condition. It is also advisable to monitor such patients closely during the initial stages of NRT use to mitigate potential adverse effects on their cardiovascular system. Thus, caution is warranted, and healthcare professionals should inform patients about the importance of professional guidance when using NRT.
