Duration and Monitoring of Quetiapine Maintenance Therapy in Bipolar Disorder

Duration of Maintenance Treatment

• The World Health Organization recommends that quetiapine maintenance therapy be continued for at least 2 years after the last bipolar episode; continuation beyond 2 years should be decided by a mental‑health specialist. 1

Periodic Reassessment of Treatment Need

• Clinical guidelines advise regular reassessment of the patient to determine whether ongoing quetiapine maintenance is still required and to adjust the dose accordingly, balancing relapse risk against long‑term side‑effects. 3

Metabolic Monitoring During Maintenance

• The American Academy of Child and Adolescent Psychiatry emphasizes that metabolic adverse effects (weight gain, hyperglycemia, dyslipidemia) must be monitored throughout quetiapine maintenance. Baseline and periodic measurements of body‑mass index, fasting glucose, and lipid panels are essential. 3
