Fluanxol should not be stopped suddenly, especially after taking it regularly for many years. Long-term use can make the body adjust to the medicine, so abrupt discontinuation may sometimes cause anxiety, sleep problems, restlessness, mood changes, dizziness, or return of the original mental health symptoms. Because she has been taking it since 2011, gradual dose reduction under medical supervision is usually considered safer. Doctors commonly reduce the dose slowly over weeks or months, depending on the reason it was prescribed, current mental health condition, age, and overall health. Regular follow-up is important during dose reduction so that any returning symptoms can be identified early. Good sleep, stress reduction, emotional support, and maintaining a stable routine may also help during the tapering process. Medicines for mental health should only be adjusted after a proper psychiatric evaluation because each person may respond differently during withdrawal. Please consult her doctor before making any changes, especially if there is anxiety, depression, confusion, sleep disturbance, aggression, or worsening emotional symptoms during dose reduction.
