What is the Chantix starter pack dosing schedule?
Chantix (varenicline) is usually started with a 7-day titration “starter pack” that increases the dose step-by-step to reduce side effects, then continues into the regular course. The standard starter-pack schedule is:[1]
- Days 1 to 3: 0.5 mg once daily
- Days 4 to 7: 0.5 mg twice daily (morning and evening)
After the starter pack, the typical maintenance dose is 1 mg twice daily starting on Day 8 (if continuing therapy as prescribed).[1]
How do you take the starter pack (timing and day-by-day changes)?
The titration is based on the day of treatment rather than your quit date. You take:
- One dose daily during Days 1–3.
- Two doses daily during Days 4–7, spaced through the day (morning and evening).[1]
What dose comes after the starter pack?
After finishing Days 1–7, the usual next step is increasing to 1 mg twice daily starting Day 8, assuming you’re continuing treatment.[1]
What if you miss a dose?
If you miss a dose, take it when you remember unless it’s close to the next scheduled dose; then skip the missed dose and resume the normal schedule. Do not double up. (Follow your prescriber’s instructions and the label directions.)[1]
Can the starter pack dose be adjusted for kidney problems?
Yes. People with reduced kidney function may need lower dosing than the standard starter pack schedule. If you have kidney disease, check with your prescriber before following the usual titration schedule.[1]
