Varenicline (Champix) – A Comprehensive Medicine to Quitting Smoking
Varenicline, commonly known by its brand name Champix, is a prescription medication designed to help individuals overcome nicotine addiction and successfully quit smoking. It’s not about simply masking the urge; it’s about retraining your brain to no longer crave cigarettes. The active ingredient, varenicline, works directly on nicotine receptors in the brain, offering a dual-action approach to cessation. While various pharmaceutical companies manufacture generic versions of varenicline, ensuring affordability and accessibility for those seeking to break free from smoking’s grip.
This medication isn’t a quick fix; it requires commitment and adherence to the prescribed treatment plan. It’s a tool that empowers you to take control, but like any powerful instrument, understanding its intricacies is crucial. Varenicline has demonstrated significant success rates in clinical trials, often surpassing other smoking cessation therapies. It represents a beacon of hope for millions struggling with this pervasive addiction.
Clinical studies consistently demonstrate varenicline’s superiority over alternatives like bupropion and placebo. In 12-week trials followed by a 40-week non-treatment phase, approximately 44% of participants achieved a 4-week quit rate compared to 30% with bupropion and just 18% with a placebo. Furthermore, continuous abstinence rates at 52 weeks were around 23% for varenicline, 15% for bupropion, and only 10% for the placebo group – numbers that speak volumes about its effectiveness.
Forms and Dosages
Varenicline is primarily available in tablet form, designed for oral administration. The tablets come in two strengths: 0.5mg and 1mg. The treatment typically begins with a low dose of 0.5mg once daily for the first three days, gradually increasing to 0.5mg twice daily for the next four days before reaching the maintenance dose of 1mg twice daily from day eight onwards. This gradual escalation minimizes potential side effects and allows your body to adjust to the medication.
The starter packs are designed with this titration schedule in mind, containing both 0.5mg and 1mg tablets to facilitate a smooth transition. It’s important not to split the tablets unless specifically instructed by your doctor, as they are formulated for controlled release of the active ingredient. The standard treatment course is 12 weeks, but can be extended up to 24 weeks based on individual needs and progress.
Who Can Take It?
Varenicline is generally intended for adults aged 18 years and older who are motivated to quit smoking. It’s suitable for both men and women, however, it’s absolutely contraindicated during pregnancy or while breastfeeding due to the potential risks to the developing baby. Smoking itself poses significant dangers during pregnancy, but varenicline’s effects on fetal development haven’t been thoroughly studied, making it a risk not worth taking.
Extra caution is advised for individuals with pre-existing psychiatric conditions, including depression or suicidal thoughts. Those with kidney disease may require dose adjustments, and anyone with a history of seizures should discuss this with their doctor before starting treatment. The elderly population might be more susceptible to side effects, necessitating careful monitoring by a healthcare professional.
How to Take Varenicline
Taking varenicline correctly is paramount for maximizing its effectiveness. The tablets should be swallowed whole with water after a meal to minimize potential nausea – an empty stomach can exacerbate this common side effect. It’s crucial to adhere to the prescribed dosage schedule, even if you feel like you’re not experiencing strong cravings. Consistency is key.
If you miss a dose, take it as soon as you remember, unless it’s almost time for your next scheduled dose. In that case, skip the missed dose and continue with your regular schedule. Never double up on doses to compensate for a missed one. Before starting varenicline, set a quit date – ideally within the first week or two of treatment. Studies show flexibility in setting this date between weeks 1-5 can still yield positive results.
How It Works
Varenicline works by cleverly mimicking nicotine’s action in the brain, but without delivering the addictive substance itself. Nicotine normally binds to receptors in the brain, creating pleasurable sensations that reinforce smoking behavior. Varenicline partially stimulates these same receptors, reducing cravings and withdrawal symptoms like irritability and difficulty concentrating.
Simultaneously, it blocks nicotine from fully binding to those receptors, diminishing the rewarding effects of smoking if you do relapse. Think of it as a double-edged sword: easing the discomfort of quitting while simultaneously making cigarettes less appealing. This unique mechanism sets varenicline apart from other cessation aids like nicotine replacement therapy (NRT), which only addresses cravings without tackling the pleasurable aspects of smoking.
Contraindications
Certain medical conditions and circumstances make varenicline unsuitable for use. Individuals with a history of psychiatric illness, particularly depression or suicidal thoughts, should not take this medication due to an increased risk of worsening these conditions. Similarly, those with active epilepsy or severe kidney disease are generally advised against using varenicline.
Allergies to varenicline or any of its ingredients are also a strict contraindication. It’s vital to inform your doctor about all existing medical conditions and medications before starting treatment to ensure safety and avoid potentially harmful interactions. Varenicline is not a one-size-fits-all solution, and careful assessment by a healthcare professional is essential.
Interactions
Varenicline can interact with other medications, potentially altering their effects or increasing the risk of side effects. It’s particularly important to avoid using nicotine replacement therapies (NRT) – such as patches, gum, or sprays – concurrently with varenicline, as this can lead to excessive nicotine exposure and adverse reactions.
Quitting smoking can also affect how your body processes certain medications like insulin, theophylline, and warfarin; therefore, close monitoring may be required if you’re taking any of these drugs. Alcohol tolerance might decrease while on varenicline, so it’s advisable to moderate alcohol consumption. Always provide a complete medication list to your doctor before starting treatment.
Side Effects
Like all medications, varenicline can cause side effects, although most people tolerate it well. Common side effects include nausea (the most frequently reported), inflammation of the nose or throat, difficulty sleeping, and headaches. These are usually mild and temporary, often subsiding as your body adjusts to the medication.
Less common but more serious side effects include mood changes, depression, and suicidal thoughts. If you experience any of these, stop taking varenicline immediately and seek medical attention. Rare but potentially severe reactions like chest pain or signs of a stroke also warrant immediate emergency care. To minimize side effects when stopping treatment, gradually taper your dose as directed by your doctor.
Overdose Risks
An overdose of varenicline can occur if you take significantly more than the prescribed dosage. Symptoms may include dizziness, confusion, nausea, vomiting, and in severe cases, seizures or cardiac arrest. If you suspect an overdose, seek immediate medical attention – call emergency services or go to the nearest hospital. It’s crucial to store varenicline securely out of reach of children and pets to prevent accidental ingestion.
Price and Availability
The price of varenicline varies depending on the dosage, quantity purchased, and whether you opt for a generic or branded version. A 2-week starter pack (containing both 0.5mg and 1mg tablets) typically costs around £42.99, while a 12-week complete course can range from £244.99.
Varenicline is available through retail pharmacies with a valid prescription. However, for convenience and discretion, many individuals choose to purchase it online from reputable sources like The Family Chemist. Online pharmacies often offer competitive pricing and discreet delivery services.

Alternatives
While varenicline is highly effective, several alternatives are available for those who prefer different approaches or cannot take this medication. Nicotine Replacement Therapy (NRT) – including patches, gum, lozenges, sprays, and inhalers – provides nicotine without the harmful chemicals found in cigarettes. Cytisine is a prescription-only course that reduces nicotine cravings.
Nicotine vapes (e-cigarettes) can also be helpful for some, but they carry the risk of prolonged nicotine dependence. Bupropion, an antidepressant, is another prescription medication used for smoking cessation. The best alternative depends on individual preferences, medical history, and the guidance of a healthcare professional.
Precautions
Before starting varenicline, inform your doctor about all existing medical conditions and medications you’re taking. Avoid alcohol consumption while on this medication, as it may worsen side effects. Store varenicline in a cool, dry place away from direct sunlight and out of reach of children. Be aware of potential mood changes or suicidal thoughts and seek immediate help if they occur.
