The nicotine inhaler is much different than an inhaler used to treat asthma or COPD. In fact, the nicotine dosing takes place in the mouth and not the lungs. Each nicotine inhaler contains 10mg of nicotine. Doses may be prescribed between 4-16 inhalers a day. Because this mode of therapy requires so much hand to mouth motion, it may be ideal for those people who find themselves needing to do something with their hands. But, since this is slowly absorbed in the mouth (not a true inhaler), it does not seem very effective in treating the withdrawal cravings.
Side effects seem to be limited to mild mouth and throat irritation. However, it does require a certain coordination to perform this therapy which may not be well executed by those with arthritis or other similar physical challenges. In addition, people with severe airway reactivity and chronic cough should not choose this form of nicotine replacement therapy.
Results are similar to the other nicotine replacement therapies. However, it is important to realize this is available by prescription only and is the most expensive form of nicotine replacement therapy available. In addition, the nicotine inhaler is used so frequently during the day, many smokers may find it more than a little annoying.
Once again, the nicotine inhaler and any other nicotine replacement therapy should only be used in combination with other therapies under the direction of a doctor.
