Chantix Continuing Pack is a medication used to help adults quit smoking. It contains the active ingredient varenicline and comes in the form of tablets. Varenicline works by attaching to nicotine receptors in the brain, blocking nicotine's effects and reducing the desire to smoke.
Chantix Continuing Pack is typically used for a 12-week treatment period, with the dose gradually increasing over the first week to lessen the chance of side effects such as nausea or unusual dreams.
Use and Dosage
The Chantix continuing pack is taken orally as a tablet and typically taken once daily initially, then twice daily in the morning and evening. It should be taken with a full glass of water after eating, at approximately the same time every day. Follow the directions on the prescription label carefully and ask a doctor or pharmacist for clarification on any unclear instructions.
The Chantix continuing pack can be used in different ways.
- One option is to set a quit date before starting treatment and begin taking Chantix continuing pack as directed by your doctor, 1 to 2 weeks before the quit date. Take the prescribed tablet once a day for the first 3 days, then twice a day for the next 4 days. Afterward, continue taking the prescribed dose twice daily for the remainder of the treatment period, which is typically 12 weeks. Gradually increase the dose to avoid side effects such as nausea or unusual dreams. Smoking is okay during the first week of Chantix use, but smoking should stop on the selected quit date.
- Another option is to start taking the Chantix continuing pack without a preset quit date, beginning with the 0.5-milligram tablets, and gradually increasing the dose as instructed by a doctor. Select a quit date between days 8 and 35 of treatment. Smoking should stop on the quit date and the prescribed dose of medication should be continued for the remainder of the treatment period.
Take the tablet exactly as directed and not take more or less than prescribed by a doctor. In cases where selecting a quit date is difficult, a doctor might suggest gradually reducing smoking during the treatment period with the goal of quitting by the end of the treatment.
