Nicorette Inhalator: How It Works, How to Use It, and Whether It's Right for You

Quitting smoking is one of the hardest things a person can do. The physical cravings are one challenge, but for many smokers, it's the ritual that's equally difficult to let go of: the act of reaching for something, raising it to your mouth, and inhaling. That behavioural habit is something most nicotine replacement products simply ignore.

The Nicorette Inhalator is designed to address both problems at once. It delivers nicotine to help manage withdrawal symptoms while also replicating the hand-to-mouth action of smoking. For people who've struggled with patches or gum, that combination can make a real difference.

This guide covers everything you need to know about the Nicorette Inhalator: how it works, how to use it correctly, who it's best suited to, and how to get the most out of it on your quit journey.

Key fact: According to NHS Stop Smoking Service data for 2024/25, the self-reported quit rate among people using NRT with stop smoking support was 54.7%. Using NRT correctly, and choosing the right product for your habits, significantly improves your chances of success.

What Is the Nicorette Inhalator?

The Nicorette Inhalator is a licensed nicotine replacement therapy (NRT) product designed to help adults stop smoking or cut down the number of cigarettes they smoke. It consists of a plastic mouthpiece and replaceable cartridges, each containing 15mg of nicotine.

Unlike a cigarette, it produces no smoke, no tar, and no carbon monoxide. It is suitable for use indoors and in most smoke-free environments, making it a discreet option for managing cravings throughout the day.

The Two Problems It Solves

Most NRT products only tackle nicotine dependency. The Nicorette Inhalator goes further by addressing the behavioural dimension of smoking as well.

Nicotine delivery: Each cartridge releases nicotine vapour that is absorbed through the lining of the mouth (the buccal mucosa) into the bloodstream, relieving withdrawal symptoms and cravings.
Behavioural replacement: The act of holding and puffing on the inhalator mimics the hand-to-mouth ritual of smoking, which can significantly reduce the psychological urge to reach for a cigarette.

This dual action makes it particularly valuable for smokers who find that patches or gum fail to address the habitual side of their dependency.

Available Pack Sizes

The Nicorette Inhalator is available in three pack sizes to suit different stages of a quit attempt:

Pack Size	Best For
4 cartridges	Trial or top-up purchase
20 cartridges	Short-term use or lighter smokers
36 cartridges	Sustained quit attempts or heavier smokers

You can browse all three options on the Kennedy's Pharmacy Nicorette Inhalator range.

How Does the Nicorette Inhalator Work?

Understanding the science behind the inhalator helps you use it more effectively and set realistic expectations for what it can and cannot do.

Nicotine Absorption Through the Mouth

When you draw air through the mouthpiece, nicotine from the cartridge is vaporised and absorbed primarily through the buccal mucosa (the lining of the mouth and throat). Minimal nicotine actually reaches the lungs, which is an important distinction from smoking.

This means the delivery is slower and steadier than a cigarette. Peak plasma nicotine levels are reached approximately 15 minutes after the end of an inhalation session, compared to seconds with a cigarette. In normal use, the inhalator achieves plasma nicotine levels of around 6-8 ng/ml, roughly one third of what cigarette smoking delivers, according to the Summary of Product Characteristics published on the Electronic Medicines Compendium.

Why You Need to Puff More Than You'd Expect

Because each puff delivers less nicotine than a cigarette drag, you need to inhale more frequently. On average, the inhalator delivers approximately 1mg of nicotine per 80 puffs. This is why many first-time users underuse the product and then conclude it isn't working.

The National Centre for Smoking Cessation and Training (NCSCT) recommends puffing for around 20 minutes per session using slow, shallow puffs to avoid throat irritation and ensure adequate nicotine absorption.

Temperature and Performance

One practical factor most guidance overlooks: temperature affects how well the inhalator works.

Below 15°C: Nicotine evaporates less readily, so you need to inhale more frequently to get the same dose.
Above 30°C: Nicotine evaporates more readily, so use less frequently to avoid overdose.
Optimal range: Room temperature (around 20°C) gives the most consistent performance.

This is particularly relevant for anyone planning to use the inhalator outdoors in cooler Northern Irish weather.

How to Use the Nicorette Inhalator

Getting the technique right from the start makes a significant difference to how effective the inhalator is. Here is a step-by-step guide.

Setting Up the Inhalator

Twist the two sections of the mouthpiece until the marks on the side line up, then pull the mouthpiece apart.
Insert a cartridge into the bottom section and push down firmly until you hear the seal break.
Push the top and bottom sections back together and twist to lock.

The inhalator is now ready to use.

Using It Correctly

Inhale through the mouthpiece using slow, shallow puffs rather than deep lung inhalation. This maximises absorption through the mouth lining and reduces the risk of throat irritation.
Use the inhalator whenever you feel the urge to smoke, or proactively before situations where you know cravings are likely.
Each cartridge provides approximately 40 minutes of intense use, which can be broken into multiple shorter sessions (for example, eight 5-minute sessions throughout the day).
The maximum daily dose is 6 cartridges.

Avoid Acidic Drinks Before Use

Avoid acidic drinks such as fruit juice or fizzy drinks for at least 15 minutes before using the inhalator. Acidity in the mouth reduces nicotine absorption efficiency.

Recommended Treatment Duration

Phase	Duration	Action
Phase 1	Up to 8 weeks	Up to 6 cartridges per day
Phase 2	2 weeks	Reduce daily cartridges by half
Phase 3	2 weeks	Gradually reduce to zero

Most people complete the full programme in 12 weeks, though treatment can be extended if needed. The goal is to reduce your reliance on the inhalator progressively until you no longer need it.

Who Is the Nicorette Inhalator Best Suited To?

The Nicorette Inhalator is not the right choice for every smoker, but for certain groups it is arguably the most effective NRT option available.

It Works Best For People Who...

Miss the hand-to-mouth habit of smoking. This is the inhalator's defining advantage over other NRT products. If you find yourself reaching for a pen or fidgeting when you're trying not to smoke, the physical act of using the inhalator can fill that gap.
Struggle with patches due to skin reactions. Approximately 40% of users experience mild local reactions with nicotine patches. The inhalator avoids this entirely.
Want flexibility in how they quit. Unlike patches, which deliver nicotine continuously, the inhalator is on-demand. You use it when you need it, which suits people with irregular smoking patterns or those who want to cut down gradually before stopping completely.
Need something discreet for use in smoke-free environments. The inhalator can be used indoors and in most public spaces where smoking is prohibited.

It May Be Less Suitable For People Who...

Have a severe nicotine dependency and need higher, more sustained nicotine delivery (a combination of the inhalator with a nicotine patch may be more appropriate in these cases).
Are pregnant or breastfeeding (speak to a pharmacist or GP before use).
Have cardiovascular conditions (NRT is still considered safer than smoking, but medical advice is recommended).
Are under 12 years of age (the inhalator is contraindicated in children under 12).

Pharmacist tip: Combining a nicotine patch with a fast-acting product like the inhalator has been shown to increase long-term quit success. NHS Stop Smoking guidance shows that combination NRT approaches achieve among the highest quit rates of any treatment method. If you're a heavier smoker, it's worth discussing this approach with one of our pharmacists.

Possible Side Effects

Like all medicines, the Nicorette Inhalator can cause side effects, though not everyone will experience them. Most are mild and tend to improve as your body adjusts to the product.

Common Side Effects

The most frequently reported side effects relate to local irritation in the mouth and throat:

Cough
Throat irritation or burning sensation
Mouth soreness or inflammation
Hiccoughs
Nausea
Headache
Dizziness
Taste disturbance

About 40% of users experience mild local reactions such as coughing or throat irritation when they first start using the inhalator. According to the product's Summary of Product Characteristics, most users adapt to this with continued use.

How to Reduce Side Effects

Use slow, shallow puffs rather than deep inhalations.
Avoid using the inhalator in very cold conditions, which can increase irritation.
If you experience persistent nausea, you may be using more cartridges than your body currently needs. Try reducing the frequency of use.

When to Seek Advice

Stop using the inhalator and speak to a pharmacist or GP if you experience:

Signs of an allergic reaction (rash, swelling, difficulty breathing)
Severe or persistent chest pain
Irregular heartbeat
Symptoms that concern you or that do not improve

Nicorette Inhalator vs Other NRT Products

The Nicorette Inhalator is one of several NRT formats available. Understanding where it sits in the landscape helps you decide whether it's the right starting point or whether a combination approach would serve you better.

Product	How Nicotine Is Delivered	Speed of Action	Addresses Habit?	Best For
Inhalator	Buccal mucosa (mouth lining)	15-20 minutes to peak	Yes	Hand-to-mouth habit, flexible use
Patch	Transdermal (through skin)	Slow, sustained	No	Consistent background coverage
Gum	Buccal mucosa	20-30 minutes to peak	Partially	Oral fixation, on-demand use
Lozenge	Buccal mucosa	20-30 minutes to peak	No	Discreet, no chewing required
Mouth spray	Buccal mucosa	60 seconds to absorption	No	Fastest relief for acute cravings

The Case for Combination NRT

The most important insight from this comparison: no single product has to be used in isolation. NHS Stop Smoking Service statistics for 2024/25 show that the highest self-reported quit rate (61%) was achieved by people using nicotine vapes alongside NRT simultaneously. For those using licensed NRT alone, combination approaches consistently outperform single-product use.

A common and effective strategy is to use a nicotine patch for steady background coverage throughout the day, then reach for the inhalator during moments of acute craving. This addresses both the physiological and behavioural aspects of dependency simultaneously.

Tips for Getting the Most Out of Your Quit Attempt

The inhalator is a tool, not a guarantee. How you use it, and what you pair it with, will determine how effective it is. These evidence-based strategies will improve your chances of success.

Use It Before the Craving Peaks

Cravings tend to build gradually. Most people wait until the urge to smoke is at its strongest before reaching for the inhalator, but by that point it's harder to resist. Use the inhalator at the first sign of a craving, or proactively before situations you know will trigger one (after meals, during a commute, with coffee).

Set a Quit Date

People who set a specific quit date are significantly more likely to succeed than those who attempt to gradually drift into quitting. Use the inhalator to bridge the gap between your current smoking level and your quit date, then switch to using it as a full replacement for cigarettes from that day.

Combine with Behavioural Support

NRT works best when combined with behavioural support. NHS Stop Smoking Services offer free advice, support, and in many cases access to NRT on prescription. Speaking with a trained stop smoking adviser significantly improves quit rates compared to using NRT alone.

Track Your Progress

Note how many cartridges you're using each week and aim to reduce that number over time.
Identify your highest-risk times of day and plan your inhalator use around them.
Celebrate milestones: one week smoke-free, two weeks, one month. The psychological reinforcement matters.

Don't Give Up After a Slip

A single cigarette does not mean the quit attempt has failed. Research consistently shows that most successful quitters made multiple attempts before stopping permanently. If you slip, restart your programme the same day.

Frequently Asked Questions

Can I smoke while using the Nicorette Inhalator?

Yes. The inhalator can be used as part of a gradual reduction approach. You use it between smoking episodes to extend smoke-free intervals, progressively reducing the number of cigarettes you smoke before stopping completely. If you are aiming to quit immediately, replace all cigarettes with the inhalator from your quit date.

How long does one cartridge last?

Each cartridge provides approximately 40 minutes of intense use, broken into sessions of around 5 minutes. Once the nicotine is depleted (usually after around 40 minutes of active use), the cartridge should be replaced. The amount of time a cartridge lasts in practice depends on how frequently and how intensively you use it.

Can I use the Nicorette Inhalator with a nicotine patch?

Yes, and this is often recommended for heavier smokers. The patch provides a steady baseline of nicotine throughout the day, while the inhalator manages acute cravings as they arise. If you are considering combination NRT, speak to a pharmacist to confirm the right approach for your level of dependency.

Is the Nicorette Inhalator the same as vaping?

No. The Nicorette Inhalator is a licensed medicine. It delivers nicotine vapour that is absorbed through the mouth lining, with minimal reaching the lungs. It contains no propylene glycol, vegetable glycerin, or flavourings associated with e-cigarettes. It is specifically designed as a short-term quit aid, not a long-term alternative to smoking.

Where can I buy the Nicorette Inhalator?

The Nicorette Inhalator is available over the counter at Kennedy's Pharmacy, both in-store and online. We stock all three pack sizes: the 4-cartridge starter pack, the 20-cartridge pack, and the 36-cartridge pack for sustained use. Our pharmacists are available to advise on which pack size and which NRT approach is right for you.

Ready to Start Your Quit Journey?

The Nicorette Inhalator is one of the most versatile and behaviorally-aware NRT products available in the UK. For smokers who struggle with the ritual as much as the nicotine itself, it offers something that patches and gum simply cannot: a physical substitute that keeps your hands and mouth occupied while managing withdrawal.

The key is using it correctly. Slow, shallow puffs. Proactive use before cravings peak. A structured reduction plan over 8 to 12 weeks. And, where appropriate, combining it with a patch for comprehensive coverage.

Kennedy's Pharmacy stocks the full Nicorette Inhalator range, along with the complete selection of Nicotine Replacement Therapy products to support every stage of your quit attempt. Our pharmacists are on hand to help you choose the right approach for your smoking habits and lifestyle.
