CHANTIX

VARENICLINE TARTRATE

Standard Dose

2 DOSAGE AND ADMINISTRATION • Begin CHANTIX dosing one week before the date set by the patient to stop smoking. Alternatively, the patient can begin CHANTIX dosing and then quit smoking between days 8 and 35 of treatment. ( 2.1 ) • Starting Week: 0.5 mg once daily on days 1–3 and 0.5 mg twice daily on days 4–7. ( 2.1 ) • Continuing Weeks: 1 mg twice daily for a total of 12 weeks. ( 2.1 ) • An additional 12 weeks of treatment is recommended for successful quitters to increase likelihood of long-term abstinence. ( 2.1 ) • Consider a gradual approach to quitting smoking with CHANTIX for patients who are sure that they are not able or willing to quit abruptly. Patients should begin CHANTIX dosing and reduce smoking by 50% from baseline within the first four weeks, by an additional 50% in the next four weeks, and continue reducing with the goal of reaching complete abstinence by 12 weeks. Continue treatment for an additional 12 weeks, for a total of 24 weeks. ( 2.1 ) • Severe Renal Impairment (estimated creatinine clearance less than 30 mL/min): Begin with 0.5 mg once daily and titrate to 0.5 mg twice daily. For patients with end-stage renal disease undergoing hemodialysis, a maximum of 0.5 mg daily may be given if tolerated. ( 2.2 ) • Consider dose reduction for patients who cannot tolerate adverse effects. ( 2.1 ) • Another attempt at treatment is recommended for those who fail to stop smoking or relapse when factors contributing to the failed attempt have been addressed. ( 2.1 ) • Provide patients with appropriate educational materials and counseling to support the quit attempt. ( 2.1 ) 2.1 Recommended Dosage for Adults Smoking-cessation therapies are more likely to succeed for patients who are motivated to stop smoking and who are provided additional advice and support. Provide patients with appropriate educational materials and counseling to support the quit attempt. The patient should set a date to stop smoking. Begin CHANTIX dosing one week before this date. Alternatively, the patient can begin CHANTIX dosing and then quit smoking between days 8 and 35 of treatment. CHANTIX should be taken orally after eating and with a full glass of water. The recommended dose of CHANTIX is 1 mg twice daily following a 1-week titration as follows: Days 1 – 3: 0.5 mg once daily Days 4 – 7: 0.5 mg twice daily Day 8 – end of treatment: 1 mg twice daily Patients should be treated with CHANTIX for 12 weeks. For patients who have successfully stopped smoking at the end of 12 weeks, an additional course of 12 weeks treatment with CHANTIX is recommended to further increase the likelihood of long-term abstinence. For patients who are sure that they are not able or willing to quit abruptly, consider a gradual approach to quitting smoking with CHANTIX. Patients should begin CHANTIX dosing and reduce smoking by 50% from baseline within the first four weeks, by an additional 50% in the next four weeks, and continue reducing with the goal of reaching complete abstinence by 12 weeks. Continue CHANTIX treatment for an additional 12 weeks, for a total of 24 weeks of treatment. Encourage patients to attempt quitting sooner if they feel ready [see Clinical Studies (14.5) ]. Patients who are motivated to quit, and who did not succeed in stopping smoking during prior CHANTIX therapy for reasons other than intolerability due to adverse events or who relapsed after treatment, should be encouraged to make another attempt with CHANTIX once factors contributing to the failed attempt have been identified and addressed. Consider a temporary or permanent dose reduction in patients who cannot tolerate the adverse effects of CHANTIX. 2.2 Dosage in Special Populations Patients with Impaired Renal Function No dosage adjustment is necessary for patients with mild-to-moderate renal impairment. For patients with severe renal impairment (estimated creatinine clearance less than 30 mL per min), the recommended starting dose of CHANTIX is 0.5 mg once daily. The dose may then be titrated as needed to a maximum dose of 0.5 mg twice daily. For patients with end-stage renal disease undergoing hemodialysis, a maximum dose of 0.5 mg once daily may be administered if tolerated [see Use in Specific Populations (8.6) , Clinical Pharmacology (12.3) ] . Elderly and Patients with Impaired Hepatic Function No dosage adjustment is necessary for patients with hepatic impairment. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function [see Use in Specific Populations (8.5) ] .

Monitoring

• 5 WARNINGS AND PRECAUTIONS • Neuropsychiatric Adverse Events: Postmarketing reports of serious or clinically significant neuropsychiatric adverse events have included changes in mood (including depression and mania), psychosis, hallucinations, paranoia, delusions, homicidal ideation, aggression, hostility, agitation, anxiety, and panic, as well as suicidal ideation, suicide attempt, and completed suicide.
• Observe patients attempting to quit smoking with CHANTIX for the occurrence of such symptoms and instruct them to discontinue CHANTIX and contact a healthcare provider if they experience such adverse events.
• ( 5.1 ) • Seizures : New or worsening seizures have been observed in patients taking CHANTIX.
• CHANTIX should be used cautiously in patients with a history of seizures or other factors that can lower the seizure threshold.

Interaction Notes

• 7 DRUG INTERACTIONS Based on varenicline characteristics and clinical experience to date, CHANTIX has no clinically meaningful pharmacokinetic drug interactions [see Clinical Pharmacology (12.3) ].
• • Other Smoking-Cessation Therapies: Safety and efficacy in combination with other smoking-cessation therapies has not been established.
• Coadministration of varenicline and transdermal nicotine resulted in a high rate of discontinuation due to adverse events.
• ( 7.1 ) • Effect of Smoking Cessation on Other Drugs: Pharmacokinetics or pharmacodynamics of certain drugs (e.g., theophylline, warfarin, insulin) may be altered, necessitating dose adjustment.
