Interactions ⬆ ⬇

Drug-Drug:

↑risk of hyperkalemia, renal impairment, and hypotension with concurrent use of ACE inhibitors or ARBs; concurrent use contraindicated in patients with diabetes or moderate-to-severe renal impairment (CCr <60 mL/min).
Blood levels are ↑ by atorvastatin, itraconazole, ketoconazole, verapamil, and cyclosporine; avoid concurrent use with cyclosporine or itraconazole.

↑risk of hyperkalemia with concurrent use of ACE inhibitors, ARBspotassium supplements, potassium-sparing diuretics, or potassium-containing salt substitutes.
NSAIDs and selective COX-2 inhibitors may blunt the antihypertensive effect and ↑ the risk of renal dysfunction.

Drug-Food:

High fat meals significantly ↓ absorption.

Patient/Family Teaching ⬆ ⬇

Instruct patient to take aliskiren as directed at the same time each day, even if feeling better. Advise patient to eat meals with similar nutrients when taking doses of aliskiren; high fat meals decrease absorption. Take missed doses as soon as remembered, but not if almost time for next dose. Do not double doses. Do not share medication with others, even with same condition; may be harmful.
May cause dizziness. Caution patient to lie down and notify health care professional. Also, avoid driving and other activities requiring alertness until response to aliskiren is known. Dehydration, excessive perspiration, vomiting or diarrhea may increase risk.
Instruct patient to avoid using potassium supplements or salt substitutes containing potassium during therapy.
Advise patient to report signs and symptoms of angioedema (swelling of face, extremities, eyes, lips, or tongue; chest tightness; difficulty swallowing or breathing; rash; hives; itching; dizziness; vomiting) to health care professional immediately.
Advise patient to notify health care professional of all Rx or OTC medications, vitamins, or herbal products being taken and to consult with health care professional before taking other medications.
Rep: May cause fetal harm. Advise females of reproductive potential to notify health care professional if pregnancy is planned or suspected and to avoid breastfeeding during therapy. If pregnancy is detected, discontinue aliskiren as soon as possible. If pregnancy occurs during therapy, serial ultrasound exams may be used to assess the intra-amniotic environment. Oligohydramnios may not appear until after the fetus has sustained irreversible injury. Closely monitor infants with histories of in utero exposure to aliskiren for hypotension, oliguria, and hyperkalemia; may require exchange transfusions.
