Drugs with Most Hospitalization Reports
All tracked drugs ranked by FAERS reports involving hospitalization.
What This Ranking Tells Us
Hospitalization reports in FAERS indicate cases where a drug-associated adverse event led to or extended a hospital stay. Widely prescribed medications naturally accumulate more reports. Blood thinners, insulin, and cardiovascular drugs often top this list because their therapeutic effects require careful dosing — too much or too little can require emergency intervention. These reports help FDA identify drugs that may benefit from improved dosing guidelines or additional monitoring requirements.

Frequently Asked Questions
What does a hospitalization report in FAERS mean?
It means an adverse event report included hospitalization (initial or prolonged) as a serious outcome. The hospitalization may have been caused by the drug, an underlying condition, or a combination. FAERS does not determine causality — it documents associations for FDA to investigate.
Are drugs with more hospitalization reports less safe?
Not necessarily. Drugs prescribed to millions of people or to severely ill populations will naturally have more hospitalization reports. A per-prescription hospitalization rate would be more informative. These rankings are useful for identifying which drugs require the most post-marketing surveillance.
Reading the Drugs with Most Hospitalization Reports
This table ranks all tracked drugs by hospital reports, sourced from FDA Adverse Event Reporting System (FAERS). The dataset is published by the relevant federal agency and updated as new reports and surveys come in. Each row links to a full drug profile so readers can move from headline number to the underlying FDA data — labeling, FAERS reports, recalls, pricing, and shortage status — that explains why a particular drug sits where it does.

Rankings are diagnostic, not prescriptive. Absolute numbers are shaped by exposure volume, reporting practices, and data-collection methodology, so a drug near the top is not automatically "worse" than a drug near the bottom — it may simply be older, more widely prescribed, or manufactured by firms with more visible reporting. Context from FDA Adverse Event Reporting System (FAERS) updates continuously, which means the relative order here can change from one refresh to the next. Rankings on this page are for educational research only and must not be used as a substitute for medical advice from a licensed clinician.
