Chantix Starting Month Pak

This medication is used in combination with a stop-smoking program (e.g., education materials, support group, counseling) to help you quit smoking. Varenicline works by blocking nicotine's actions in the brain. Quitting smoking decreases your risk of heart and lung disease, as well as cancer.

If you miss a dose, take it as soon as you remember. If it is near the time of the next dose, skip the missed dose and resume your usual dosing schedule. Do not double the dose to catch up.

Read the Medication Guide provided by your pharmacist before you start taking varenicline and each time you get a refill. If you have any questions, consult your doctor or pharmacist. Follow your doctor's directions carefully. Before beginning treatment with this drug, set a date to quit smoking. Begin taking varenicline 1 week before the quit date as follows unless directed otherwise by your doctor. When you first start taking this medication, take one 0.5-milligram tablet once a day for 3 days, then increase to one 0.5-milligram tablet twice a day for 4 days. The dose is slowly increased to lessen the chance of side effects (e.g., nausea, unusual dreams). During this first week, it is okay to smoke. Stop smoking on the quit date and begin taking the dose prescribed by your doctor twice a day for the rest of the 12-week treatment period. If this medication comes in a dosing package, carefully follow the directions on the dosing package. There are two types of dosing packs, a starting pack and a continuing pack, each containing different strengths of this medication.

Dosage is based on your medical condition and response to therapy. Do not increase your dose or take this medication more often than prescribed. Your condition will not improve any faster, and the risk of serious side effects may be increased. Do not take more than 1 milligram twice a day. Use this medication regularly to get the most benefit from it. To help you remember, take it at the same time(s) each day. Inform your doctor if you continue to smoke after a few weeks of treatment. If you are successful and cigarette-free after 12 weeks of treatment, your doctor may recommend another 12 weeks of treatment with varenicline.
