It is not necessarily dangerous to apply Nicoderm if your blood pressure is 152/84 mmHg, but it is important to monitor your blood pressure regularly, especially during the quitting process. Nicotine withdrawal can sometimes cause an increase in blood pressure. If your blood pressure remains stable or improves over time, there is no need to worry. Make sure to measure your blood pressure consistently in the morning and evening to track any changes. If you have any concerns or questions, it is always a good idea to consult with a healthcare professional. Good luck with your journey to quit smoking!
