Varenicline is gaining popularity for the treatment of nicotine dependence. General treatment guidelines recommend monitoring for behavioral changes in patients with a mental illness. There are very few cases reported on patients developing psychiatric symptoms with no previous history. We are reporting the case of a Spanish patient who had developed a first-psychotic episode after he was started on varenicline. He was ultimately diagnosed with a paranoid personality disorder. Therefore, prior to starting a patient on varenicline, the clinician must identify possible paranoid and other cluster A personality traits. It is essential to monitor for new onset of psychotic symptoms during the treatment with this drug.
