Champix (Varenicline) Buyer and Patient Handbook in Singapore

What is Champix?

Champix is a prescription tablet that belongs to the partial nicotine-receptor agonist class and is used to help adults stop smoking. It works by reducing cravings and the pleasurable sensations of nicotine. Champix is approved by the Health Sciences Authority (HSA) of Singapore and is available in .5 mg and 1 mg strengths.

Who Should Use Champix?

• Adults (≥18 years) who smoke ≥10 cigarettes per day
• Individuals motivated to quit and prepared for a structured cessation plan
• Patients without severe renal impairment (creatinine clearance ≥30 ml/min)

How Does It Work?

Champix binds partially to the α4β2 nicotinic acetylcholine receptors in the brain. Think of it as a “partial dimmer switch” for nicotine: it delivers a low level of stimulation to curb cravings while blocking the full effect when a cigarette is smoked. This dual action helps reduce withdrawal symptoms and the rewarding “high” from smoking. There is a low but present risk of neuropsychiatric effects; seek help if mood changes occur.

Why Choose Champix?

• Efficacy: Clinical trials show up to 2-fold higher quit rates compared with placebo.
• Convenient dosing: Once-daily tablets after the initial titration phase.
• Generic alternatives: Varenicline tablets are available at lower cost with identical bioavailability.

Dosage, Administration, Lifestyle and Dietary Recommendations

Recommended Dosage

• Days 1-3: .5 mg once daily

Overdose

Seek immediate medical attention if you ingest ≥10 mg at once. Call Singapore’s emergency number 995 and inform staff of the exact amount taken.

Special Populations

• Elderly (≥65 years): Start with the standard titration; monitor for dizziness.
• Renal impairment: Reduce the total daily dose to 1 mg (.5 mg twice daily) if creatinine clearance is 30-60 ml/min.
