From the Guidelines
The maximum recommended duration for taking Chantix (varenicline) is up to 1 year, as extended therapy may be necessary to promote continued cessation. According to the NCCN clinical practice guidelines in oncology 1, a minimum of 12 weeks of combination NRT or varenicline is recommended for the initial quit attempt, and therapy may be extended to promote continued cessation for 6 months to 1 year. This guideline suggests that while there is a recommended minimum duration, the treatment can be extended as needed to support smoking cessation. Some key points to consider when taking Chantix include:
- The standard treatment course is 12 weeks, but an additional 12-week course may be recommended if you've successfully quit smoking but need more support to remain smoke-free 1.
- The medication works by binding to nicotine receptors in the brain, reducing cravings and withdrawal symptoms while blocking the pleasurable effects of nicotine if you do smoke.
- It's essential to follow your doctor's specific instructions regarding duration, as they may adjust the treatment period based on your individual response and needs.
- Nicotine withdrawal symptoms typically peak within 1–2 weeks of quitting and then subside, and patients who do not quit immediately may quit at some later point after withdrawal symptoms subside 1.
- Pharmacotherapy dose adjustments may be considered, as clinically indicated, and track attempts at smoking reduction, considering switching to a different pharmacotherapy if reduction efforts stall 1.
