Nicotine replacement therapy should usually be made available to any habitual cigarette smoker including pregnant women making an attempt to quit smoking. However NRT is not suitable for those who do not have the motivation to quit or are not willing to undergo nicotine withdrawal symptoms.
About Nicotine Replacement Therapy for Smoker :
NRT should normally be recommended in blocks generally for duration of two weeks. They should be sustained in those abstaining from cigarettes for a period of six to eight weeks, and then stopped. Acquiring nicotine from NRT is fairly safe in comparison to obtaining nicotine from cigarettes, since the patient is not subjected to any of the numerous harmful effects associated with the combustion of tobacco.
Use of NRT for prolonged periods of time is not supposed to be linked with any severe harmful consequences. The use of NRT is suitable in conditions in which nicotine from cigarettes might be harmful, for example in pregnancy, cardiovascular disease or in adolescents. The use of nicotine replacement therapy is considered safe for smokers with stable cardiovascular disease. In severe cardiovascular conditions, for example unstable angina, severe myocardial infarction or stroke, NRT should be cautiously used since nicotine is a vasoconstrictor.
Medicinal nicotine is less harmful compared to nicotine and accompanying tar, carbon monoxide and other products from cigarettes. It is suitable to make available NRT to patients with severe cardiovascular disease who cannot stop smoking.
In these circumstances it is advisable to utilize quickly reversible preparations, for example gum, inhalator, nasal spray or lozenge. It’s because the absorption of nicotine stops when the product is taken off. Smoking all through pregnancy and in the period following it creates a severe threat to the health of the mother as well as the baby. Unlike nicotine from cigarettes, NRT’s effects on placental function and fetal development may not be severe. But still it can pose some problems. However, the magnitude may not be as intense in comparison to nicotine obtained directly from cigarettes.
Total abstinence from all forms of nicotine should therefore be the main aim in pregnancy and breast feeding. A large number of pregnant women are successful in their effort to quit smoking without any pharmacological support. However, for those who fail in their attempt to quit smoking or those who have failed in their previous attempts to quit smoking, the utilization of NRT to aid pregnant women to quit smoking is reasonable with respect to the dangers of sustained smoking. Pregnant or breast feeding women who try NRT should do well to use products the effects of which last for a shorter duration of time to reduce fetal exposure to prolonged effects of nicotine.
