Uses for nicotine
Nicotine inhaler is used to help you stop smoking. Nicotine is absorbed in the mouth and throat and enters the blood stream. This replaces the nicotine you would get from smoking and makes the withdrawal effects from not smoking less severe. The amount of nicotine is decreased over time until use is stopped.
Nicotine is available only with your doctor’s prescription.
Before using nicotine
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For nicotine, the following should be considered:
Tell your doctor if you have ever had any unusual or allergic reaction to nicotine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
Appropriate studies have not been performed on the relationship of age to the effects of inhaled nicotine in the pediatric population. Safety and efficacy have not been established. Small amounts of nicotine can cause serious unwanted effects in children, and the inhaler contains enough nicotine to cause problems, including used cartridges.
Although appropriate studies on the relationship of age to the effects of inhaled nicotine have not been performed in the geriatric population, no geriatric-specific problems have been documented to date. However, elderly patients are more likely to have age-related kidney, liver, or heart problems, which may require caution and an adjustment in the dose for patients receiving inhaled nicotine.
|All Trimesters||D||Studies in pregnant women have demonstrated a risk to the fetus. However, the benefits of therapy in a life threatening situation or a serious disease, may outweigh the potential risk.|
Studies in women breastfeeding have demonstrated harmful infant effects. An alternative to this medication should be prescribed or you should stop breastfeeding while using nicotine.
Interactions with medicines
Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. When you are taking nicotine, it is especially important that your healthcare professional know if you are taking any of the medicines listed below. The following interactions have been selected on the basis of their potential significance and are not necessarily all-inclusive.
Using nicotine with any of the following medicines is usually not recommended, but may be required in some cases. If both medicines are prescribed together, your doctor may change the dose or how often you use one or both of the medicines.
Interactions with food/tobacco/alcohol
Certain medicines should not be used at or around the time of eating food or eating certain types of food since interactions may occur. Using alcohol or tobacco with certain medicines may also cause interactions to occur. Discuss with your healthcare professional the use of your medicine with food, alcohol, or tobacco.

- Angina (severe chest pain) or

Proper use of nicotine
Use nicotine only as directed by your doctor. Do not use more of it, do not use it more often, and do not use it for a longer time than your doctor ordered.
Nicotine should come with patient instructions. Read and follow these instructions carefully. Ask your doctor or pharmacist if you have any questions.
You should stop smoking completely before you start using nicotine. Do not use any tobacco products during therapy. If you continue to smoke with the inhaler, you may have serious unwanted effects from nicotine.
It is also important to use a stop-smoking program that may include education, counseling, and psychological support. This may make it easier for you to stop smoking.
