Understanding Quetiapine Dosage: Guidelines and Recommendations
Quetiapine, an atypical antipsychotic, is commonly prescribed for the treatment of various mental health conditions, including schizophrenia, bipolar disorder, and major depressive disorder. The medication works by altering the effects of neurotransmitters in the brain, particularly serotonin and dopamine, which play significant roles in mood regulation. Achieving the correct dosage is crucial for maximizing treatment benefits while minimizing potential side effects.
