Varenicline and nicotine replacement therapy (NRT) are both FDA-approved quit-smoking medicines, and both are among the seven the CDC lists as safe and effective for adults who smoke. They work in very different ways. Here’s how they compare, so you can have a better conversation with your doctor.

Prescription?	Yes	No (inhaler and nasal spray: yes)
When to start	Usually 1 week before your quit date	On your quit date
Typical length	About 12 weeks	About 8–12 weeks, stepping down
Common side effects	Nausea, sleep problems or vivid dreams, constipation, gas	Skin irritation (patch), mouth or jaw soreness, hiccups, heartburn

How varenicline is taken

According to the CDC, there are two ways to start. You can pick a quit date and start varenicline one week before it, so the medicine builds up first. Or you can start the pills and then set a quit date 8 to 35 days later. The dose starts low and increases over the first week: one 0.5 mg pill a day for days 1–3, one 0.5 mg pill twice a day for days 4–7, then 1 mg twice a day. Most people take it for about 12 weeks. Taking it with food and a full glass of water helps reduce nausea. Your prescriber will tell you the exact schedule for you.

What about mood side effects?

Varenicline used to carry the FDA’s most serious “boxed” warning about mood and behavior changes. In 2016, the FDA approved removing that boxed warning after a large study of more than 8,000 people (called EAGLES) found that people taking varenicline were no more likely to have serious mood-related side effects than people taking a placebo.

Mood changes can still happen, though rarely. The CDC advises that if you notice hostility, agitation, depression, or suicidal thoughts that you don’t think are caused by quitting itself, stop the medicine and call your doctor right away. Also tell your doctor about new or worsening heart symptoms, and be careful driving until you know how the medicine affects you.

Which might suit you?

Whichever you choose, adding counseling or a quit program improves your odds. The CDC says combining counseling with medication gives you the best chance of quitting for good. Whether you can combine varenicline with NRT is a question for your prescriber.

How to get a varenicline prescription online

You don’t have to wait for an in-person appointment. Your options:

1. Your regular doctor or nurse practitioner. Many offer video or phone visits. Ask about varenicline by its generic name.
2. A telehealth service. Several online services offer quit-smoking visits and can prescribe varenicline or bupropion where appropriate, often within a day. Self-pay visits commonly start around $40–$80. [VERIFY: current prices for any service named or linked here]
3. Your quitline. Call 1-800-QUIT-NOW. Coaches can help you get medicine through your insurance or community programs.

Whoever you see will review your health history, including kidney health, pregnancy, and mental health, before prescribing. Be open with them; it helps them choose the safest option for you.

What does it cost?

Generic varenicline is widely available. Many insurance plans cover quit medicines at no or low cost, so check with your insurer first. Without insurance, compare pharmacy prices and discount programs before you fill the prescription. NRT costs vary by brand; store brands are usually cheapest, and NRT is often FSA/HSA eligible.
