Rare (less than 0.1%): Anaphylaxis^[Ref]

Two cases of angioedema with respiratory symptoms were reported with aliskiren use in clinical studies, and two other cases of periorbital edema without respiratory symptoms were reported as possible angioedema and resulted in discontinuation. The rate of angioedema cases in completed studies was 0.06%. Twenty-six other cases of edema involving the face, hands, or whole body were reported with aliskiren use, including four which led to discontinuation. In the placebo controlled studies, the incidence of edema involving the face, hands or whole body was 0.4% with aliskiren compared with 0.5% with placebo.^[Ref]

Metabolic

Frequency not reported: Edema, peripheral edema

Aliskiren:

Uncommon (0.1% to 1%): Elevated uric acid, gout, renal stones

Postmarketing reports: Peripheral edema, hyponatremia
