Everything You Need to Know About Varenicline and Quitting Smoking

Thinking about quitting? Varenicline is one of the most popular prescription options to help you break the habit. It works by blocking nicotine receptors in the brain, so cravings drop and withdrawal feels milder. This page gives you the basics you need before you talk to your doctor.

How Varenicline Works

When you start a varenicline course, the drug partially activates nicotine receptors, giving a gentle signal that reduces the urge to smoke. At the same time, it blocks nicotine from binding, so smoking a cigarette won’t give the usual buzz. The result is fewer cravings and less pleasure from smoking, making it easier to stay smoke‑free.

Getting Started: Dosage, Safety, and FAQs

The typical schedule begins with a low dose for three days, then ramps up to a full dose taken twice a day for 12 weeks. Common side effects include nausea, vivid dreams, and mild headache, but most people find them manageable. If you have any kidney issues, mood changes, or are pregnant, talk to your physician before starting.
