Only one type of stop smoking medication should be used at a time. They should not be used together.
*Champix production restarted June 2025. Varenicline is medically the same but unbranded. How is generic varenicline different to branded Champix?
Quit rate doubled with smoking cessation mediation
Clinical studies have shown that taking Champix/varenicline or cytisine can more than double the rate of success in stopping smoking compared with dummy (placebo) tablets.
How Champix/varenicline and cytisine work
Varenicline and cytisine work by attaching to the same receptors in the brain as nicotine to block its effects. This causes less cravings for cigarettes and allows a gradual reduction in nicotine dependence and increases the likelihood you will stop smoking.
Champix/varenicline
How to use
Champix/varenicline tablets are taken twice-daily, usually for 12 or 24 weeks.
The dose is built up over a week, starting 1-2 weeks before target stop smoking date. You can purchase a starter pack which contains both doses needed for the initial 2 weeks of treatment or separate packs of Champix/varenicline doses of 0.5mg and 1mg.
| Days of treatment | Dosage and frequency |
|---|---|
| Days 1-3 | 0.5mg once a day |
| Days 4-7 | 0.5mg twice a day |
| Day 8 onwards | 1mg (or 2 x 0.5mg) twice a day |
The dose can be reduced to 0.5mg twice a day if the higher dose is not tolerated.
An alternative version of the treatment schedule which you may find easier to follow (from the National Centre for Smoking Cessation and Training).
The complete course is for 12 weeks. It can be repeated for a further 12 weeks if there are still significant withdrawal symptoms, or you have reduced but are unable to completely stop smoking in the first 12 weeks.
Champix/varenicline cautions
Dr Fox cannot supply Champix/varenicline if you have a diagnosis of the following conditions:
- An allergy to varenicline or any other non-active ingredients in the tablets.
- A psychiatric illness.
- Active depression.
- Seizures, or a condition that makes you more likely to have a seizure.
- Renal failure/severe kidney disease - you will likely need a reduced dose and monitoring by your usual GP.
- Are pregnant or breastfeeding.
When the course of treatment comes to an end, some people experience poor sleep and low mood/depression for a few days. This chance could be reduced by lowering the dose gradually before stopping treatment. To do this, once the course has been completed, reduce to 0.5mg twice a day for a week then 0.5mg once a day for a week.
It is rare but possible to feel suicidal after stopping Champix/varenicline - if this occurs you must seek medical advice immediately.
Champix/varenicline may also cause you to have a lower tolerance to alcohol.
Driving and skilled tasks
When starting this medication you should ensure you do not experience dizziness or sleepiness before driving.
Champix/varenicline possible side effects
Varenicline is usually well tolerated, however the most common side effects include headache, nausea, nose or throat inflammation, difficulty sleeping, and abnormal dreams.
For a full list of possible side effects please see the varenicline patient information leaflet.
Cytisine
How to use
Each tablet contains 1.5mg of cytisine and the course is for 25 days. Tablets are taken increasingly less frequently over the course of the 25 days.
Your quit smoking date should be no later than day 5. Continued smoking may worsen any treatment reaction.
| Days of treatment | Recommended dosing | Maximum daily dose |
|---|---|---|
| From the 1st to the 3rd day | 1 tablet every 2 hours | 6 tablets |
| From the 4th to the 12th day | 1 tablet every 2.5 hours | 5 tablets |
| From the 13th to the 16th day | 1 tablet every 3 hours | 4 tablets |
| From the 17th to the 20th day | 1 tablet every 5 hours | 3 tablets |
| From the 21st to the 25th day | 1-2 tablets a day | 2 tablets |
An alternative version of the treatment schedule which you may find easier to follow (from the National Centre for Smoking Cessation and Training).
Each day, following your 1st dose of cytisine, we suggest you set a reminder/alarm for the next dose. If you miss a dose of cytisine you should not take a double dose to make up for it, just take the next dose as indicated.
Cytisine cautions
Cytisine should not be used, and Dr Fox cannot therefore supply cytisine, if you have any of the following conditions:
- Hypersensitivity to cytisine or any of the non-active ingredients (mannitol, microcrystalline cellulose, magnesium stearate, glycerol dibehenate, and hypromellose).
- Unstable angina - chest pain due to reduced blood supply to the heart that occurs at rest and minimal exercise. Your GP or cardiologist should be able to advise if you are unsure.
- Had a heart attack within the last 6 weeks.
- A clinically significant abnormal heart rhythm. Your GP or cardiologist should be able to advise you if you are unsure.
- Had a stroke within the last 6 months.
- Are taking anti-tuberculosis drugs.
- Are pregnant or breastfeeding.
Cytisine possible side effects
Cytisine is usually well tolerated, however you may experience the following side effects: change in appetite, weight gain, headache, increased heart rate, increased blood pressure, dizziness, irritability/mood changes, sleep disorders, nausea, vomiting, heartburn, change in taste, constipation, abdominal pain, muscles aches, rash.
For a full list of side effects please read the manufacturer's cytisine patient information leaflet.
