Psychiatric Medicines

Certain mental health problems, such as moderate and severe depression, certain anxiety disorders, bipolar disorder, psychoses, etc. require medication due to their biological basis. Medications can restore chemical imbalances in the brain that cannot be adequately addressed by psychotherapy or other alternative approaches alone.
A combination of medication and psychotherapy is often the most effective approach for many mental disorders. Medication provides immediate and safe symptom relief, allowing patients to recover, function daily, and benefit more effectively from psychotherapeutic interventions.
