After a puff of smoke, the nicotine level in the blood rises sharply. Nicotine medicines raise it more slowly and to a lower level, and cytisine contains no nicotine at all. Cytisine and all forms of nicotine, that is, patches, chewing gum, mouth spray and lozenges, are available in pharmacies without a prescription. Cochrane is an international network of researchers who gather the results of clinical trials and check how reliable they are. In the network's 2023 review, stop-smoking medicines were compared on the basis of 319 studies.
The Cochrane review assessed how well medicines worked by looking at how many patients were not smoking after at least six months. The differences shown compare treatment with placebo or no medicine.
How does cytisine work?
Desmoxan, Tabex and Recigar contain cytisine, an alkaloid of plant origin. Cytisine attaches to nicotinic receptors and stimulates them more weakly than nicotine, which eases withdrawal symptoms. By occupying these receptors, it also weakens the effect of nicotine from a cigarette smoked during treatment. After a tablet is swallowed, cytisine reaches its highest blood level in just under an hour on average, and its half-life, the time it takes the body to clear half of the medicine, is about 4 hours.
On days 1 to 3, the patient swallows a tablet every 2 hours, up to 6 a day in total. The intervals between tablets then get longer, and in the last days of the 25-day course 1 or 2 tablets a day are enough. The patient stops smoking by day 5 at the latest. With cytisine, 7 more people in every 100 treated quit smoking than with placebo or no medicine. In September 2026, a full course of cytisine cost about PLN 40 to 78. Women who are pregnant or breastfeeding must not take cytisine. The doctor will also not choose it if the patient has recently had a heart attack or stroke, or has unstable angina or significant heart rhythm disorders.
How does a nicotine patch work?
A patch releases nicotine through the skin slowly and without sharp rises in level. With the NiQuitin Przezroczysty 21 mg per day patch, the blood nicotine level settles after the second patch is applied. It is then less than half the average level during half an hour of smoking cigarettes. The patient wears the Nicorette Invisipatch from waking up until going to bed, and the nicotine level in the blood is highest about 9 hours after it is applied.
That is why a patch eases withdrawal symptoms throughout the day, but will not help within minutes when a sudden urge to smoke comes. With a patch alone, 2 more people in every 100 quit smoking than without medication. In September 2026, NiQuitin patches for a whole ten-week course meant spending about PLN 606 to 930.
How do gum, spray and lozenges work?
From gum, spray and lozenges, nicotine is absorbed through the lining of the mouth, so it works faster than from a patch. After a 2 mg dose of Nicorette Spray, the nicotine level in the blood is highest after about 13 minutes. A NiQuitin MINI lozenge usually dissolves in the mouth within 10 minutes. With Nicorette Classic Gum, the highest nicotine level comes 5 to 10 minutes after chewing stops. The patient reaches for these medicines when the urge to smoke comes.
For fast-acting forms of nicotine, the combined result was about 3 more non-smokers in 100 compared with placebo or no medicine. The doctor may also combine a patch with gum, spray or lozenges. In the review, this combination proved only slightly less effective than cytisine, but the authors could not be sure the difference was not due to chance. In September 2026, 4 mg gum in packs of 105 cost PLN 78 to 100. A spray with 150 doses cost less, PLN 62 to 85.
Are varenicline and bupropion available in Poland?
Champix contains varenicline, which, like cytisine, acts on nicotinic receptors. Zyban contains bupropion, an antidepressant. In the review, 8 more people in 100 quit smoking with varenicline and 3 more with bupropion. Both medicines are available only on prescription. In September 2026, Champix was not available in any of the pharmacies we checked, and Zyban has had no valid marketing authorisation since December 2023. So the doctor in Bydgoszcz usually chooses between cytisine and nicotine medicines.
