Nicotine Patch

The nicotine patch is also an over-the-counter form of nicotine replacement therapy. It provides uniform delivery of nicotine through the skin and come in many different types and strengths.

A 24-hour pack provides continuous nicotine delivery and provides 24-hour relief of nicotine withdrawal symptoms, particularly those experience surely in the morning, but might interfere with sleep during the night.

A 16 nicotine patch is less likely to interfere with sleep during the night since it is applied in the morning, but probably will not provide relief of nicotine withdrawal symptoms experienced in the early morning.

Most smokers depending on their body size should begin with the full strength (15-16 mg per day) patch can continue with it for four weeks before (5-4 mg per day) patch to be used for an additional four weeks.  

According to recommendations from the Food and Drug Administration, the patches should not be used for more than 3-5 months.
