What is a Nurse Practitioner?

A Nurse Practitioner (NP) is a registered nurse with advanced clinical training who is authorized to assess, diagnose, treat, and manage a wide range of health conditions — independently or in collaboration with other members of a healthcare team.

In Ontario, NPs are regulated by the College of Nurses of Ontario and have the authority to order and interpret diagnostic tests, prescribe medications, and refer to specialists. They provide many of the same services as a family physician, with a strong emphasis on patient education, prevention, and holistic, relationship-based care.

Irena Ushamirsky, NP brings over a decade of nursing experience and an NP designation to her role at NatCan — making her a trusted primary care provider for patients seeking an integrative, comprehensive approach to their health.

Iron Infusion Therapy

Iron Infusion Therapy for Iron Deficiency

Iron deficiency is one of the most common nutritional deficiencies — and one of the most frequently underdiagnosed. If oral iron supplements haven't worked, or if you need faster, more effective replenishment, IV iron infusion therapy may be the right solution.

What Is Iron Infusion Therapy?

Iron infusion therapy involves the intravenous delivery of iron directly into the bloodstream, bypassing the digestive system entirely. This allows for faster, more complete iron replenishment compared to oral supplements — particularly beneficial for patients who cannot tolerate oral iron, have absorption issues, or require rapid restoration of iron stores.

At NatCan, iron infusions are assessed and administered by Irena Ushamirsky, NP, who evaluates each patient's iron levels, symptoms, and health history before recommending a treatment plan.

  • Faster iron replenishment than oral supplements
  • Bypasses digestive absorption issues entirely
  • Suitable for patients who cannot tolerate oral iron (nausea, GI upset)
  • Improves fatigue, brain fog, shortness of breath, and cold intolerance
  • Supports patients with heavy menstrual bleeding, pregnancy-related deficiency, or chronic conditions
  • Administered and monitored by a licensed Nurse Practitioner
Signs You May Benefit

Could Iron Deficiency Be Affecting You?

Iron deficiency can present in many ways and often goes unrecognized. Common signs include:


  • Persistent fatigue or low energy — even with adequate sleep, feeling exhausted throughout the day is one of the most common signs of iron deficiency.


  • Brain fog or difficulty concentrating — iron plays a key role in oxygen delivery to the brain; low levels can affect focus, memory, and cognitive performance.


  • Shortness of breath or heart palpitations — reduced oxygen-carrying capacity can cause breathlessness during everyday activities.


  • Hair loss or brittle nails — iron is essential for healthy hair follicle function; deficiency is a leading cause of non-hormonal hair thinning.


  • Feeling cold all the time — iron deficiency impairs the body's ability to regulate temperature effectively.


  • Oral iron hasn't worked or isn't tolerated — if supplements cause GI distress or haven't raised your levels, IV infusion therapy may be the right next step.

FAQ

Common Questions

What can a Nurse Practitioner help me with at NatCan?
Irena Ushamirsky, NP offers primary care consultations, iron infusion therapy, women's health assessments, hormone replacement therapy (HRT) management, preventive care, health screening, and chronic condition co-management. She can order and interpret diagnostic tests, prescribe medications, and refer to specialists — many of the same services you would receive from a family physician, with a strong emphasis on individualized, patient-centred care.
Who is a good candidate for iron infusion therapy?
Iron infusion therapy may be recommended for patients who have confirmed iron deficiency or iron deficiency anemia, cannot tolerate oral iron supplements due to gastrointestinal side effects, have not responded adequately to oral supplementation, have absorption issues affecting oral iron uptake, or require faster iron replenishment (e.g. during pregnancy or before surgery). A consultation with Irena is the first step — she will assess your iron levels and health history to determine whether infusion therapy is appropriate for you.
Is iron infusion therapy safe?
Yes — iron infusion therapy is a well-established, safe treatment when properly assessed and administered by a qualified healthcare provider. Irena assesses every patient before treatment and monitors throughout the infusion session. Mild side effects such as temporary flushing or minor discomfort at the IV site can occasionally occur, but serious reactions are rare. Your safety is the priority at every step.
Do I need a referral to see Irena?
No referral is required to book a consultation with Irena at NatCan. New patients are welcome to book directly online or by calling us at 416-400-6280 Ext. 1. If you are coming for iron infusion therapy, Irena will complete a health assessment at your first visit before administering treatment.
Is this service covered by OHIP or extended health benefits?
Coverage varies depending on the specific service and your health plan. Some Nurse Practitioner services may be eligible for OHIP coverage. Iron infusion therapy and extended health benefit coverage depends on your specific plan. We recommend contacting us or checking with your insurance provider in advance. Our team is happy to help clarify what to expect before your appointment.
Where is this service available?
Irena Ushamirsky, NP sees patients exclusively at NatCan Integrative Medical & Wellness Centre, located at 3905 Major MacKenzie Dr W, Unit 102, Vaughan, ON. This service is not currently available at our Woodbridge location.
What is the difference between a Nurse Practitioner and a Naturopathic Doctor at NatCan?
A Nurse Practitioner (NP) like Irena operates within the conventional medical system — she can diagnose, prescribe medications, order labs, and provide primary care in a similar scope to a family physician. A Naturopathic Doctor (ND) uses a root-cause, integrative approach that draws on evidence-based natural therapies alongside conventional medicine. Both work collaboratively at NatCan, and many patients benefit from seeing both depending on their needs. Irena and our NDs communicate and collaborate to ensure you receive the most comprehensive care possible.
