This is one of my fears with Polia (from drugs.com). My immune system is already on the deficient side.

"Yes, Prolia (denosumab) does appear to weaken your immune system. Research has shown people who take Prolia are at an increased risk of serious infections leading to hospitalizations, including serious infections of the skin, abdominal, urinary tract, and ear. There is also a higher chance of developing endocarditis (an infection of the heart’s inner lining, usually involving the heart valves) in those who take Prolia, and those with advanced kidney disease have an increased risk of severe, life-threatening, low calcium levels (hypocalcemia) developing, particularly if they have a metabolic condition called chronic kidney disease-mineral bone disorder (CKD-MBD). For some side effects, people administered concomitant immunosuppressant agents (such as prednisone or cyclosporine) or with impaired immune systems may be at an even higher risk.

Doctors may need to consider discontinuing Prolia in people who develop serious infections or other severe side effects."
