What the FAERS Data Reveals About telmisartan Side Effects

The FDA Adverse Event Reporting System (FAERS) contains 33,611 voluntary reports linked to telmisartan and its brand equivalents (Micardis), spanning 2001 through 2025. Of those, 3,166 (9.4%) listed death as an outcome and 14,967 (44.5%) involved hospitalization. The most common indication reported alongside adverse events was Hypertension.

Demographic breakdowns help contextualize who is being exposed to the drug. Of reports with known sex, 56% were female and 44% male; age distribution skews toward 75+, with 7,961 reports in that bracket. The single most reported reaction is nausea with 2,059 submissions, followed by fatigue and drug ineffective.

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.
