About this active substance

Nicotine is a chemical naturally found in plants of the Solanaceae family, such as tobacco. It is primarily used in nicotine replacement products, such as patches, gum, or nasal sprays, to help people quit smoking. Nicotine acts on the central nervous system, stimulating the release of dopamine, which can create a sense of pleasure and addiction.

Nicotine replacement products are designed to reduce withdrawal symptoms and help smokers gradually quit smoking. It is important to use these products as directed to avoid overdose or other adverse effects.

Side effects may include irritation at the application site (in the case of patches), nausea, dizziness, or insomnia. In rare cases, excessive use may lead to nicotine toxicity, requiring immediate medical attention.

Patients should inform their doctor about any other medications being used or pre-existing conditions, such as cardiovascular diseases, as these may affect the safety of using nicotine-containing products.
