The recommended dosage depends on the type of smoking cessation drug. Each form of this medicine comes with detailed instructions for its use. Following directions exactly is very important. For example, nicotine gum should not be chewed like regular chewing gum. Nicotine patches and other products also must be used correctly to be effective.
Precautions Seeing a physician regularly while using smoking cessation drugs is important.
The physician will check to make sure the medicine is working as it should and will watch for unwanted side effects. Do not smoke during treatment with smoking cessation drugs that contain nicotine, as this could lead to nicotine overdose. For the same reason, do not use more than one type of smoking cessation product at a time, and never use more than the recommended amount of medicine. Even a small amount of nicotine can seriously harm a child or animal. Nicotine in any form should not be used during pregnancy , as it may harm the fetus or cause miscarriage .
