Abstract

Since its launch as a smoking cessation aid, varenicline use has been linked to a number of serious adverse events, notably the exacerbation of pre-existing psychiatric illness, depressed mood and suicidal ideation. Regulators’ fears have been somewhat allayed by varenicline's status as a prescription only medication. The purpose of this study was to examine the care provided by physicians – or general practitioners – and pharmacists to varenicline users under real-world conditions. Participants were 141 patients who had filled a prescription for varenicline at a participating pharmacy within the previous six-months. Identified patients were mailed a survey to complete that included items on interactions with their physician and pharmacy staff, and knowledge of treatment side-effects. Most participants reported that their physician encouraged them to set a quit date (82.5%) and provided additional cessation materials (57.2%). While most (79.0%) physicians discussed whether varenicline was appropriate for the patient, fewer asked about psychiatric illness (40.1%), or asked to be informed about mood or behaviour change during treatment (48.1%). Participants (78.4%) reported that their physician had discussed a follow-up consultation, but only 59.4% of patients who had finished treatment at the time of the survey reported having one. Most reported discussing potential drug side-effects with their physician (71.0%) and or pharmacist (52.9%); when probed, knowledge was variable. These results suggest that many patients do not receive the level of support that physicians and pharmacists are assumed to provide.
