Nicorette gum is used as an aid in smoking cessation. It works by providing low levels of nicotine, which may help you to quit smoking by lessening the physical signs of withdrawal symptoms

Use Nicorette exactly as it was prescribed for you. Ask your doctor or pharmacist if you have any questions.

Get emergency medical help if you have any of these signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue, or throat. Stop using Nicorette and call your doctor at once if you have any of these serious side effects:
seizures; or
chest pain or uneven heartbeats.

Before using Nicorette, tell your doctor if you are using any of the following drugs:
imipramine (Tofranil);
oxazepam (Serax);
propranolol (Inderal), labetalol(Normodyne, Trandate), or prazosin (Minipress);
theophylline (Theo-Dur, Theochron, Theolair);
pentazocine (Talwin), or
insulin

If overdose is suspected, contact your local poison control center or emergency room immediately. US residents can call the US national poison hotline at 1-800-222-1222 or 911. All other residents residents should call their local poison control center directly.

Do not smoke while you are using Nicorette. Stop smoking as soon as your treatment begins. Smoking while using this medication can be dangerous.

Since Nicorette is used as needed, you may not be on a dosing schedule. If you are using the medication regularly, use the missed dose as soon as you remember. If it is almost time for the next dose, skip the missed dose and wait until your next regularly scheduled dose. Do not use extra medicine to make up the missed dose.

Nicorette gum contains nicotine, the primary ingredient in tobacco products. It provided nicotine levels lower than those associated with smoking.
