In patients prescribed irbesartan, what is a major risk due to the medication's actions?

The choice indicating "Risk for injury" is pertinent to patients prescribed irbesartan because this medication is an angiotensin II receptor blocker (ARB) used primarily for hypertension and to protect kidney function in patients with diabetes. One of the effects of irbesartan is to lower blood pressure, which can lead to hypotension, especially during the initial phase of treatment or when the dosage is adjusted.

When blood pressure is lowered significantly, it can result in symptoms such as dizziness, lightheadedness, or even fainting, particularly when standing up quickly (a condition known as orthostatic hypotension). These symptoms increase the risk of falls and subsequent injuries, especially in elderly patients or those with comorbid conditions that might affect balance or coordination.

In contrast, fluid overload is typically less associated with irbesartan since it helps to manage blood pressure and does not cause retention of fluid like some diuretics. The risk for low blood sugar or nutritional deficiencies is also not directly linked to the medication, as irbesartan does not influence glucose metabolism or nutritional absorption in a manner that would cause these conditions. Thus, the primary concern about irbesartan is the potential for injury resulting from decreased blood pressure.
