Chantix

• Smoking cessation: To help adults quit smoking by reducing cravings and withdrawal symptoms. It is often used as part of a quit-smoking program that includes behavioral counseling.

Off-label uses: It's also been used for the off-label treatment of nicotine dependence in people with mental illnesses and as an aid in the cessation of smokeless tobacco.

• Hypersensitivity to varenicline or any of the ingredients in the formulation.
• A history of serious allergic reactions or skin reactions to varenicline.

• Set a quit date within the first 1 to 2 weeks of starting the medication. Chantix is most effective when patients are motivated to quit smoking.
• Take the medication after eating and with a full glass of water to reduce the likelihood of nausea, which is a common side effect.
• Be aware that vivid dreams or sleep disturbances are common. If these side effects become bothersome, consult your healthcare provider.
• Avoid drinking alcohol, as Chantix can increase sensitivity to alcohol in some patients, potentially leading to unusual or aggressive behavior.
• Contact their healthcare provider if they experience mood changes, depression, or suicidal thoughts, as Chantix has been associated with neuropsychiatric side effects in some patients.
• Stay hydrated and follow their quit-smoking plan closely for the best chances of success.

• Bupropion (Zyban): Another prescription medication used for smoking cessation, which works by affecting neurotransmitters in the brain.
• Nicotine replacement therapy (NRT): Including nicotine patches, gum, lozenges, nasal sprays, and inhalers to reduce cravings and withdrawal symptoms.
