Could Amitriptyline Be Causing Symptoms Of Iron Deficiency Anemia, Such As Shortness Of Breath And Fast Heart Rate?

I m prone to iron deficiency anemia (F40, iron deficiency runs in both sides of my family) and have recently started taking amitriptyline for migraine. I have started experiencing symptoms of iron deficiency anemia (short of breath, fast heart rate, pale skin) but my diet hasn t changed. Could it be caused by the amitriptyline?
