The prolonged agonist effect of Chantix on the release of dopamine and norepinephrine may have resulted in an acute psychotic episode in this patient.
A 42-year-old woman with schizophrenia had been treated for 17 years with 1015 mg of thiothixene.
She had several brief psychotic episodes per year, which seldom lasted for more than 3 days. She had no overt psychotic symptoms during an office visit one month previously.
Her usual symptoms during acute psychotic episodes were voices commenting on her behavior, confusion, and angry outbursts.
She smoked one to two packs of cigarettes per day and had made several attempts to discontinue the use of nicotine chewing gum and trandermal nicotine patches.
The patient’s mother reported a 5-day psychotic episode that began with increased activity, primarily the discarding of financial statements.
At day 4, the patient ordered her daughter out of the house, and she threw away her thiothixene, which her daughter had insisted that she continue to take. She spent the next day screaming in her closet.
Her mother administered thiothixene (20 mg) on the fifth evening and fed her because she had stopped eating. She appeared well groomed the next morning, without psychotic symptoms.
She had no explanation for her sudden relapse and remission, but she announced with pride that her internist had prescribed a new medication, varenicline (2 mg), to help her stop smoking. The patient had been receiving varenicline for 5 days, and her quit day was the following day.
She was advised to continue thiothixene, to avoid varenicline, and to return to nicotine chewing gum as a smoking substitute. She had no further exacerbations, but she continued to smoke cigarettes.[...]
