Are psychiatric consultations and treatments with Guillemin, a Psychiatrist, covered by Régie de l'assurance maladie du Québec (RAMQ) in QC?

Medically necessary consultations, diagnostic assessments, and medication management provided by a licensed Psychiatrist like Guillemin are generally covered by Régie de l'assurance maladie du Québec (RAMQ) in QC when a referral from a family doctor is in place.

Specific medications may also require special authorization or be subject to formulary restrictions.

Do I need a referral to see Guillemin, a Psychiatrist?

Yes, a referral from your family physician or another medical doctor (e.g., a pediatrician for child psychiatry, or an ER physician for urgent assessment) is almost always required to see a Psychiatrist such as Guillemin for services covered by the provincial health plan. Mental health conditions often benefit from initial assessment by a primary care provider who can determine the need for specialist psychiatric care. The referral ensures coordinated care, appropriate triaging, and transfer of relevant medical history.

What if I experience side effects from medication prescribed by Guillemin?

It's common for psychotropic medications to have potential side effects, especially when starting a new medication or adjusting a dose. Guillemin will discuss common side effects to watch for. If you experience side effects, it's very important to communicate this to Guillemin or her office promptly. Do not stop taking your medication suddenly unless instructed to do so by Guillemin, as this can sometimes cause withdrawal symptoms or a worsening of your condition. Guillemin can help manage side effects by adjusting the dosage, switching to a different medication, or suggesting strategies to mitigate them.

What does a Psychiatrist like Guillemin specialize in?

A Psychiatrist is a medical doctor (MD) who has completed specialized training in psychiatry, which is the branch of medicine focused on the diagnosis, treatment, and prevention of mental, emotional, and behavioral disorders. Unlike psychologists, psychiatrists can prescribe medication. She is a Psychiatrist who assesses, diagnoses, and treats mental, emotional, and behavioral disorders through medication, psychotherapy, or other interventions. Guillemin is trained to assess both the mental and physical aspects of psychological problems and can provide a range of treatments including psychotherapy, medications, and sometimes other interventions like ECT or rTMS.

What is the main difference between a Psychiatrist like Guillemin and a Psychologist?

The main difference is that a Psychiatrist, like Guillemin, is a medical doctor (MD) who has completed medical school and then specialized residency training in psychiatry. Because they are physicians, psychiatrists can diagnose mental health conditions, prescribe and manage psychotropic medications, and provide various forms of psychotherapy. They can also order medical tests to rule out physical causes of psychiatric symptoms. A Psychologist typically has a doctoral degree (PhD or PsyD) in psychology and is trained in psychological assessment, diagnosis, and providing psychotherapy (talk therapy). Psychologists generally cannot prescribe medication in Canada, though they often work closely with psychiatrists or family doctors who do.
