Smoking Cessation
Champix
Champix (varenicline) is a prescription medication that helps people quit smoking by reducing cravings and withdrawal symptoms. It works differently from nicotine replacement therapy by targeting the same brain receptors that nicotine affects. Champix is typically used as part of a comprehensive smoking cessation program that includes counseling and support.
Nicotine Replacement Therapy (NRT)
Nicotine Replacement Therapy provides controlled doses of nicotine without harmful chemicals from cigarettes. Available as patches, gum, lozenges, inhalers, and nasal spray.
Zyban
Zyban (bupropion) is a prescription medication that helps people quit smoking by reducing cravings and withdrawal symptoms. Originally developed as an antidepressant, it was found to be effective for smoking cessation. Zyban does not contain nicotine and works by affecting brain chemistry to reduce the urge to smoke. It is most effective when combined with behavioral support and counseling.

Tobacco smoking remains the leading preventable cause of death and disease in the European Union. According to WHO data, tobacco kills approximately 700,000 people in the EU each year. The health consequences of smoking are well-established: it is causally linked to lung cancer, chronic obstructive pulmonary disease (COPD), cardiovascular disease, stroke, and numerous other serious conditions. Despite widespread awareness of these risks, nicotine dependence is a recognised chronic relapsing disorder that makes cessation profoundly difficult without appropriate support.
Nicotine acts on reward pathways in the brain, producing dependence through both physical and psychological mechanisms. When a smoker attempts to quit, withdrawal symptoms — including cravings, irritability, anxiety, difficulty concentrating, and disturbed sleep — can be severe and are a primary driver of relapse. This is why the Organização Mundial da Saúde classifies tobacco dependence as a medical condition warranting tratamento.
Clinical evidence consistently demonstrates that the combination of pharmacological support and behavioural counselling produces the highest cessation rates. The EMA has approved two receita médica medications specifically for smoking cessation: varenicline (sold under the brand name Champix) and bupropion (originally an antidepressant, repurposed for smoking cessation). Nicotine replacement therapy (NRT) — available in patch, gum, lozenge, inhaler, and nasal spray formulations — provides another effective option for reducing withdrawal symptoms.
Access to evidence-based smoking cessation support through a qualified medical professional can significantly improve the chances of a successful and sustained quit attempt.
Available tratamentos
The following medications may be available for smoking cessation through EU-registered médicos. This comparison is provided for informational purposes only.
| Medication | Active Ingredient | Class | Typical Course Duration |
|---|---|---|---|
| Varenicline (Champix) | Varenicline | Nicotinic receptor partial agonist | 12 weeks (extendable to 24) |
| Bupropion | Bupropion HCl | Atypical antidepressant (NDRI) | 7–9 weeks |
| Nicotine replacement therapy | Nicotine | NRT (patch, gum, lozenge, inhaler) | 8–12 weeks |
Key distinctions:
- Varenicline (Champix): Considered the most effective single pharmacotherapy for smoking cessation in clinical trials, with quit rates approximately three times higher than placebo at 12 months. Taken as a standard comprimido twice daily after an initial titration period. Not suitable for adolescents under 18.
- Bupropion: An atypical antidepressant with dopamine and noradrenaline reuptake inhibition activity. Supports cessation by reducing cravings and withdrawal. Important contraindications include seizure history and eating disorders.
- Nicotine replacement therapy: Reduces withdrawal symptoms by providing nicotine without tobacco combustion products. Over-the-counter formulations are available without receita médica; higher-dose or combination NRT may be discussed with a médico.

Frequently asked questions
- Posso obter smoking cessation medication online na Europa?
- Yes. Prescrivia connects pacientes with independent EU-registered médicos who can review your health profile and, where clinically appropriate, issue a receita médica for smoking cessation medication. The assessment is completed online and the medication is delivered by a licensed EU farmácia.
- O que é varenicline (Champix) and how does it work?
- Varenicline is a partial agonist of nicotinic acetylcholine receptors. It reduces cravings by partially stimulating nicotine receptors in the brain, and reduces the rewarding effects of smoking by blocking nicotine from fully binding to those receptors. Clinical trials demonstrate significantly higher quit rates compared to placebo and comparable or superior efficacy to bupropion.
- Is bupropion safe for everyone?
- Bupropion is contraindicated in pacientes with a history of seizures, eating disorders, bipolar disorder, or those taking monoamine oxidase inhibitors (MAOIs). It also has interactions with various other medications. A thorough medical assessment is essential before it is prescribed. The reviewing médico will evaluate your full health profile.
- Do I need receita médica medication to stop smoking?
- Not necessarily. Many people successfully quit using over-the-counter nicotine replacement therapy (NRT) — patches, gum, lozenges, and inhalers — without receita médica medication. However, receita médica medications such as varenicline and bupropion have demonstrated higher cessation rates in clinical trials and may be appropriate for those who have not succeeded with NRT alone or who have a high level of nicotine dependence.
- Quanto tempo dura a course of smoking cessation medication typically last?
- The standard tratamento duration for varenicline is 12 weeks, with an optional additional 12-week course to further consolidate abstinence. Bupropion tratamento is typically 7–9 weeks. Nicotine replacement therapy is generally utilizado para 8–12 weeks, though duration may be extended based on individual need.
