Patch, gum or spray: which one should I use?

"Which one" is the most asked question, and the least decisive

There is a wall of boxes in the pharmacy, a price on each of them, and you would like somebody to tell you which one to take. That exact question has been put to research properly: randomise who gets a patch and who gets a fast-acting form, then count who is still not smoking six months later.

The Cochrane review that collects those trials is not about whether NRT works — that was settled long ago. It is about how to use it: which forms, which doses, for how long. It runs to 68 studies and 43,327 participants.

On the head-to-head comparison of a fast-acting form against a patch — eight studies, 3,319 participants — the verdict is one number: risk ratio 0.90, 95% confidence interval 0.77 to 1.05. No detectable difference. And this is not a shrug for lack of data: Cochrane rates it high-certainty evidence, its top grade. The plain language summary puts it flatly — "people who smoke have the same chance of quitting successfully whether they use a nicotine patch or another type of NRT, such as gum, lozenge or nasal spray."

So the twenty minutes you spend in front of the shelf are not where this gets decided. It gets decided in the next two sections.

What decides it is how many

The same review compared one form against two used together: a patch, releasing nicotine steadily, plus a fast-acting form taken when a craving arrives.

The NHS gives the same instruction without the arithmetic. "NRTs are most effective when you combine them with each other and with other stop smoking products", and, more concretely: "The best approach is to combine a fast-acting source of nicotine, like a mouth spray with a slow-acting source of nicotine like a patch that eases you out of dependence without tipping you into withdrawal."

One thing not to conclude from any of this. The other big Cochrane review — the one that compares NRT against nothing, 133 studies and 64,640 participants — also reports a number per form: gum 1.49, patch 1.64, lozenges and tablets 1.52, inhalator 1.90, nasal spray 2.02. That looks like a league table. It isn't one. Each of those figures comes from different trials, against placebo, in different populations. The only trials that put two forms against each other are the ones above, and they separate nothing.

The second lever is the dose

Two comparisons from the review, both pointing the same way:

• 4 mg versus 2 mg nicotine gum: risk ratio 1.58 (1.29 to 1.93), 5 studies, 1,075 participants, high-certainty evidence;
• 21 mg versus 14 mg patches (24-hour format): 1.48 (1.06 to 2.08) — but from a single study of 537 participants, so imprecision drops the certainty to moderate.

The plain language summary states the same finding in product terms: people using higher-dose patches — "25 mg patches worn for 16 hours, or 21 mg patches worn for 24 hours" — were more likely to quit than people on 15 mg or 14 mg equivalents.

And the ceiling, which is just as useful to know: a 42 or 44 mg patch does no better than a 21/22 mg one, at 1.09 (0.93 to 1.29). Going up helps to a point, then it stops helping.

The NHS translates all of that into two sentences you can act on today: "If you're a heavier smoker, you should start with a higher strength", and "use as many NRTs as you need to help you manage your cravings." Under-dosing is the common failure here, not overdoing it.

So which one do you actually buy?

Since the trials do not settle it, the choice goes back to being practical — which is good news, because you are the only person who knows the practical part. How fast you need relief. Where you are when cravings hit. What you can take out in front of colleagues. What you can stand the taste of.

Two things matter more than the brand:

• Gum has a techniqueThe NHS gives the principle in one line: "you chew the gum and then rest it on the inside of your cheek to deliver nicotine through the lining of your mouth and throat." France's Tabac info service spells out the full protocol — chew about ten times, park the gum under your tongue, wait five minutes without chewing, then repeat on the other side, "for 30 minutes, three times on each side." A piece is not a thirty second gesture.
• The patch comes in two formats24-hour and 16-hour. The choice is worth making deliberately if you are sleeping badly, which is a subject of its own with a measured effect of the patch on insomnia.

What the NHS says exactly

The NHS gives the clearest public instructions on NRT anywhere, and they read better in the original than in summary:

"NRTs are products that give your body lower amounts of nicotine, but without the dangerous chemicals in cigarettes." — "They are safe, proven to work and can double your chances of quitting for good." — "It's recommended that NRTs are used for about 12 weeks or for as long as they're needed to stop you from smoking again."

One gap is worth flagging, because it shows up the moment you read both sources. The NHS says "double your chances". The measurement says 50 to 60%. The exact figure comes from the Cochrane review of NRT against control: risk ratio 1.55 (1.49 to 1.61), high-quality evidence, 133 studies, 64,640 participants — summarised by its own authors as NRT increasing "the rate of quitting by 50% to 60%". The British "double" is a rounding for communication. The real number is still large for something you can buy over a counter.

The thing almost nobody does: start before

There is one more result in the review, and it is counter-intuitive: starting NRT before your quit date, while you are still smoking, rather than on the day itself. Nine studies, 4,395 participants, risk ratio 1.25 (1.08 to 1.44).

Certainty is moderate, limited by risk of bias, and Cochrane flags the caveat itself — starting before quit day "may help more people to quit than only using it after a quit day, but more evidence is needed to strengthen this conclusion." The NHS does not push it in its public pages. So this is a question to raise with a pharmacist or a stop smoking adviser rather than a decision to make alone in an aisle — but it is a real question, with a real number behind it.

Where to start

Use the free help before buying anything. The NHS asks for it in as many words — "before using an NRT, speak to a healthcare professional so they can help you choose the right product, or combination of products" — and local stop smoking services exist precisely to turn everything above into two decisions: which fast-acting form, and what strength alongside the patch. Then give it the twelve weeks the NHS asks for, rather than the two weeks it takes to feel better.

Loutra doses nothing and replaces none of that. It does the other half of the job, the half no patch does: one check-in a day, a count of the days you have not smoked, and a history that stays intact when a day goes badly. Nicotine replacement handles the withdrawal. The rest is twelve weeks of showing up.
