Question 11

What is the FDA approval status of Varenicline?

Accepted Answer

FDA Approval and Indications

Varenicline was approved by the U.S. Food and Drug Administration (FDA) as a prescription medicine to help adults stop smoking. It is designed to interfere with the receptors in the brain that respond to nicotine, thereby reducing the urge to smoke and easing withdrawal symptoms.

Neuropsychiatric Safety Communications

For several years, the FDA required varenicline to carry a boxed warning—the agency’s most serious warning—regarding neuropsychiatric events. This included reports of serious changes in behavior, agitation, depressed mood, and suicidal thoughts. In 2016, after reviewing a large clinical trial that compared varenicline to other cessation methods, the FDA determined that the risk of these side effects was lower than previously suspected. Consequently, the boxed warning was removed, though these potential side effects remain listed in the warnings and precautions section of the drug label.

Cardiovascular and Alcohol Warnings

The FDA has also issued communications regarding the cardiovascular safety of varenicline. Clinical reviews suggested a small, increased risk of certain cardiovascular adverse events in patients with existing heart disease. Additionally, the FDA updated the drug label to include warnings about decreased tolerance to alcohol and a potential increased risk of seizures in some patients. Patients are advised to monitor their mood and behavior closely and to discuss any history of heart disease or seizures with their healthcare provider before use.

Question 12

What should I know about Varenicline and withdrawal?

Accepted Answer

Potential Withdrawal Symptoms

When you stop taking varenicline, you may experience certain symptoms as the medication leaves your system. These effects are generally mild but can be bothersome for some individuals. Reported symptoms include:

Increased irritability or frustration
Strong urges or cravings to smoke
Difficulty falling or staying asleep (insomnia)
Vivid, unusual, or unpleasant dreams
Feelings of depression

Managing Discontinuation

In clinical studies, approximately 3% of people experienced an increase in irritability or sleep problems after finishing their course of varenicline. Because these symptoms closely mimic nicotine withdrawal, it can be difficult to determine if they are caused by the medication ending or the absence of nicotine.

It is important to complete the full course of treatment as prescribed by your healthcare provider. If you are concerned about side effects when stopping the medication, talk to your doctor. They may suggest gradually reducing the dose rather than stopping abruptly to help minimize discomfort.
