The most commonly reported side effects of aliskiren come from 2,229 reports to the FDA, broken down here by frequency, patient demographics, and serious outcomes.

This page analyzes 2,229 reports to the FDA Adverse Event Reporting System (FAERS) for aliskiren (Tekturna): the reactions reported most often, who reported them, serious outcomes such as hospitalization, and year-over-year trends. A FAERS report does not prove the drug caused the effect, and report volume tracks how widely a drug is used, not how likely an effect is for any one person.

How to read these numbers

FAERS is a signal-detection tool, not a scorecard. Reports are voluntary, and a single case may list multiple suspect drugs, so numbers above should not be read as incidence rates or per-patient risk. Widely prescribed drugs naturally accumulate more reports than niche therapies even when individual risk is low. These aggregates are useful for spotting patterns that merit further pharmacovigilance, not for choosing between medications.
