The Canadian Task Force lists it among recommended quit medications.
Cytisine is a natural health product that mimics the effects of nicotine, and in Canada you can buy it without a prescription. That is how Health Canada describes it, and it is the main thing to know before you start looking for it. The rest of this page covers what the department says about dosing, where it is sold and how it sits beside other quit aids.
What is cytisine?
Health Canada’s quit guide calls cytisine a natural health product that mimics the effects of nicotine. Its quit planner adds that cytisine is approved in Canada as a natural health product that does not require a prescription. We found no price, brand name or success figure for cytisine on those pages, so we do not give any.
Is there a dosing schedule?
Yes. Health Canada says there is a specific dosing schedule to follow when taking cytisine. We do not reproduce a schedule here, because the department’s page does not list one and a product label or pharmacist will give you the exact steps for the product you buy. It helps to read it before you buy.
Where can you get it?
The Health Canada infographic describes cytisine as available online and in certain stores and pharmacies. Because it is sold without a prescription, you do not need a doctor’s visit first. You can still ask for one, and a pharmacist can tell you what they stock.
How does it compare with other quit aids?
Health Canada’s infographic sorts quit aids by how much they raise your chance of quitting:
- Nearly three times the chance: varenicline with counselling, or a long-acting plus a short-acting nicotine replacement product.
- Almost double the chance: one nicotine replacement product, bupropion alone, or counselling alone.
The infographic gives cytisine its availability note and no multiplier, so we cannot place it on that scale. The Canadian Task Force on Preventive Health Care, in its 2025 guideline, lists cytisine alongside bupropion, nicotine replacement therapy and varenicline among its recommended medications. It also lists counselling, brief advice, phone counselling and text-message programs, and says combined support is recommended.
Who should you ask?
Start with a pharmacist, who can explain a product label and what else you take. A family doctor or nurse practitioner can talk through cytisine against varenicline, bupropion and nicotine replacement. The national quit line, 1-866-366-3667, is a toll-free number for talking to a quit coach. Coverage rules are in quit smoking medications and coverage, and some provinces let pharmacists help directly, as described in pharmacy smoking cessation programs.
If you are still comparing options, how to choose your quit method walks through them, and nicotine replacement products in Canada covers the over-the-counter alternatives.
What we could not confirm
We have not confirmed any drug-plan coverage for cytisine, side effects, who should avoid it or how long a course lasts. A doctor or pharmacist is the right source for those questions.
