Acute generalized exanthematous pustulosis caused by varenicline

Mucocutaneous complications of smoking cessation therapies

Despite widespread knowledge of the morbidity and mortality associated with smoking, this addictive practice continues to be quite prevalent throughout the United States, as about one-fifth of the population smokes cigarettes. Because of the financial burden, and the significant psychosocial and health implications of smoking, many individuals are now attempting to quit, and often using some type of pharmacotherapy for assistance. Given that dermatologists will likely encounter patients using smoking cessation aids, it is important to be aware of their potential mucocutaneous adverse effects. We present a brief review of the dermatologic complications associated with smoking cessation therapies. Hopefully, this article will also remind dermatologists to encourage smoking cessation at every visit.

Varenicline for tobacco dependence: panacea or plight?

INTRODUCTION

This review examines the postmarketing experience with varenicline, including case reports, newer clinical trials and secondary analyses of large clinical datasets.

AREAS COVERED

Varenicline has been shown to be an effective treatment in a broad range of tobacco users with medical, behavioral and diverse demographic characteristics. Recent studies finding excellent safety and efficacy in groups of smokers with diseases including chronic obstructive pulmonary disease are particularly encouraging and call for increased use of this medication for smoking cessation. Despite case reports of serious neuropsychiatric symptoms in patients taking varenicline, including changes in behavior and mood, causality has not been established. Recent analyses of large datasets from clinical trials have not demonstrated that varenicline is associated with more depression or suicidality than other treatments for smoking cessation.

EXPERT OPINION

Now that additional clinical trials in specific populations and observational studies on treatment-seeking smokers outside of clinical trials have been published, we can be confident that varenicline remains the most efficacious monotherapy for smoking cessation and that its side-effect profile remains good. The risk-to-benefit ratio of receiving varenicline to quit smoking must include the increased chances of quitting smoking and avoiding the sizeable risks of smoked-caused disease and death that remain if tobacco addiction is not properly treated.
