Nicotine substitutes: instructions for use

IRIS Prévention
5 August 2026
Nicotinic substitutes are effective allies in quitting smoking, provided they are used correctly. Here's how to take advantage of it.

Among the aids to quitting smoking, nicotine substitutes have proven themselves: they significantly increase the chances of success. However, they are often used incorrectly, under-dosed or stopped too early. Properly understood, they relieve withdrawal and make it easier to stop. Instructions for using these precious allies.

1. What are substitutes for?

Nicotine replacements provide nicotine without the toxic substances of smoke. They relieve withdrawal symptoms (cravings, irritability) that lead to smoking again, while allowing time to break habits. They do not contain the thousands of harmful compounds found in cigarettes.

2. The different shapes

ShapeUsage
PatchContinuous delivery throughout the day
Chewing gumQuick action on desires
PastilleQuick action, discreet
CombinationPatch + quick shape according to need

The patch ensures substantive diffusion, while the oral forms (gums, lozenges) respond to occasional desires. Combining them is often recommended for good coverage.

3. Mistakes to avoid

Common errors are underdosing (insufficient dose in relation to consumption) and stopping too early. Appropriate dosage and sufficient duration are essential. Contrary to popular belief, properly used substitutes do not create problematic dependence and are much safer than tobacco.

    • Adapt the dose to actual consumption
    • Do not stop substitutes too early
    • Combine patch and oral form if necessary

4. Get advice

The doctor or pharmacist can help choose the appropriate form and dosage, and adjust as you stop. Substitutes can be covered by prescription. Support further increases the chances of success.

Used properly, nicotine substitutes are an effective and safe support for quitting smoking. Talking to a professional optimizes their use.
