Įfficacy and safety of the novel selective nicotinic acetylcholine receptor partial agonist, varenicline, for smoking cessation. Patients with pronounced renal dysfunction (creatinine clearance less than 30 mL per minute ) should take half the usual dose. Patients unable to tolerate the side effects at the maintenance dose should have the dose lowered temporarily or permanently. If a patient relapses during the 12 weeks of therapy or after therapy is completed, he or she should be encouraged to make another attempt to quit once contributing factors have been identified and addressed. At the start of the second week, the dose is increased to 1 mg twice daily and continued for 12 weeks. The initial dose is 0.5 mg once daily starting one week before the quit date and increased to 0.5 mg twice daily after three days. Chantix free 30 day trial 2018 full#Varenicline is taken with a full glass of water twice daily after a meal. Patients who smoke one pack per day will spend an average of $130 per month on cigarettes. This is more than the cost of generic sustained-release bupropion ($116) but less than the cost of Wellbutrin SR ($150). PRICEĪ one-month supply of varenicline will cost approximately $120 for the maintenance dose. Also, varenicline has not been studied in patients who use tobacco products other than cigarettes or in patients who have significant cardiopulmonary disease or psychological disorders. Varenicline has not been compared with nicotine replacement therapy or for use in combination with other smoking cessation therapies. Two studies found that treatment with varenicline had similar results to treatment with bupropion, 5, 7 and one study found better abstinence rates with varenicline at one year compared with bupropion (23.0 versus 14.6 percent, respectively). Varenicline treatment seems to be as effective or more effective than treatment with sustained-release bupropion. In other words, for approximately every nine patients treated with varenicline instead of placebo, one additional patient will remain abstinent for one year. 3 – 7 Based on these studies, about 20 percent of patients taking varenicline will be continuously abstinent from smoking one year after treatment compared with less than 10 percent of patients taking placebo. ![]() Most patients (approximately 90 percent) had tried to quit at least once. 5 – 7 On average, patients had been smokers for 20 to 25 years and reported smoking approximately one pack per day. Varenicline has been compared with placebo in five studies 3 – 7 and with sustained-release bupropion (Wellbutrin SR) in three studies of healthy persons highly motivated to quit smoking. The rate of discontinuation because of side effects was 12 percent for patients receiving varenicline compared with 10 percent for patients receiving placebo. Other common adverse effects that occur in more than 10 percent of patients include headache, insomnia, abnormal dreams, and flatulence. Although the nausea is not typically severe, it may persist for the duration of treatment in a small number of persons. The most common adverse effect associated with varenicline is nausea, which occurs in about 30 percent of patients taking the maintenance dose. Food and Drug Administration pregnancy category C. Because smoking may alter the metabolism of some medications (e.g., warfarin, theophylline), dosing adjustments of other drugs the patient is receiving may need to be made upon smoking cessation. There are currently no known drug interactions, and the safety of varenicline used in combination with other smoking cessation therapies has not been established. Because varenicline is excreted by the kidney, the manufacturer recommends reducing the dosage in patients with impaired renal function. Studies of more than 4,500 patients have established a favorable safety profile for varenicline, and there have been no reports of abuse or serious safety issues.
