Cytisine

A plant-derived medication that works similarly to varenicline and has a long history of use in some countries.

What it is

Cytisine is a plant-based partial nicotine-receptor agonist used for smoking cessation for decades, particularly in Central and Eastern Europe, and available in more markets in recent years.

How it works

Like varenicline, it stimulates nicotine receptors partially, reducing withdrawal and blocking nicotine reward. Treatment courses are typically shorter (around 3–4 weeks).

Evidence

Cochrane reviews found cytisine increases quit success versus placebo, and a 2019 randomized trial found it non-inferior to varenicline with fewer adverse events. It is among the most cost-effective cessation medications.

Evidence strength: Moderate

Reported community experiences

Community reports of cytisine are less common in English-language communities; where reported, people describe reduced craving with nausea and sleep disturbance as notable side effects. Community records are being compiled in the Experience Database.

Practical considerations

  • Availability varies by country: it is prescription-only in some markets and pharmacy-sold in others
  • Discuss use with a pharmacist or doctor
  • Report side effects as with any medication
