Description:
Aliskiren can cause injury and death to the developing fetus by acting directly on the renin-angiotensin system, which is critical for fetal development. This carries a boxed warning from the FDA.
Actionable advice:
This should be strictly avoided during pregnancy; it should be discontinued as soon as pregnancy is detected.

Description:
NSAIDs (like ibuprofen or naproxen) can reduce the blood pressure-lowering effect of aliskiren and increase the risk of kidney damage, especially in the elderly or dehydrated individuals.

Description:
Patients with poor kidney function are at a higher risk for adverse effects like hyperkalemia and further decline in renal function when taking aliskiren.
