For your first psychiatric appointment with Hasey, it's helpful to gather some information beforehand.

If you experience side effects, it's very important to communicate this to Hasey or his office promptly. Do not stop taking your medication suddenly unless instructed to do so by Hasey, as this can sometimes cause withdrawal symptoms or a worsening of your condition. Hasey can help manage side effects by adjusting the dosage, switching to a different medication, or suggesting strategies to mitigate them.

How is confidentiality handled in psychiatric care?

Confidentiality is a cornerstone of psychiatric care. Information you share with Dr. Hasey and his team is kept private and protected by law and professional ethics. This means your information will not be disclosed to anyone without your explicit consent, except in very specific situations where there is a legal obligation or an immediate risk of serious harm to yourself or others (e.g., imminent risk of suicide or homicide, child abuse, or a court order). Dr. Hasey will typically discuss the limits of confidentiality with you at the beginning of your treatment.

Does Hasey offer psychotherapy (talk therapy)?

Many psychiatrists, including potentially Hasey, are trained in various forms of psychotherapy (talk therapy) and may offer it as part of their treatment approach, either as a standalone treatment or in combination with medication. The specific types of psychotherapy offered can vary (e.g., Cognitive Behavioral Therapy - CBT, psychodynamic therapy, supportive therapy). It's best to inquire directly with Hasey's office or discuss this during your initial consultation to understand his approach to therapy and if it's a service He provides or if He would refer you to another mental health professional like a psychologist or social worker for more intensive or specialized psychotherapy if needed.
