A stop smoking patch looks like an extra-large sticking plaster that is stuck on the skin. It releases nicotine that is absorbed slowly through the skin ensuring that the individual does not get addicted to another form of nicotine. The nicotine patch has another advantage: it does not contain the other harmful chemicals present in cigarettes.

It also helps people to get through the withdrawal period relatively easily, because their bodies are constantly absorbing small amounts of nicotine. This reduces the craving for cigarettes, and also reduces restlessness, irritability, anxiety, headaches, dizziness, constipation, insomnia and tiredness.

You can use a patch that releases a higher dose of nicotine initially and then taper off the dose by using patches that release smaller doses. Some patches release nicotine for 16 hours, while others release it for 24 hours.

This allows the smoker to regulate the nicotine intake. However, it is yet to be established as to what is more beneficial: gradual reduction in the dose of nicotine or its sudden stoppage. Similarly, it is difficult to say whether 24-hour patches are more effective than 16-hour patches.

A nicotine patch should be applied to a clean area between the neck and the waist that is free of hair. It usually doubles the rate of success for people who are motivated to give up smoking, as compared to those who rely only on their willpower and the advice of a doctor.

Pregnant women, however, need to be careful about using nicotine patches, since nicotine may slow down the growth of the baby. Those with high blood pressure and heart problems also need to be cautious about using nicotine patches. Similarly, people with diabetes, stomach ulcers, severe liver or kidney problems, or an over active thyroid gland need to consult their doctor before using a nicotine patch.
