Database median
1430.0% of 14 reports involved a death outcome. Read alongside breed popularity, veterinary access, and owner awareness — these shape how many events ever reach the FDA. The 12% comparison line is the rough cross-breed median in the FDA CVM database; values above suggest higher reporting bias toward severe outcomes, not necessarily higher true mortality.

Lusitano Pet Health Insights
Across the FDA Center for Veterinary Medicine adverse event database, Lusitano accounts for 14 submitted reports and currently ranks #404 by report volume within the horse population. Of those reports, 2 involved a death outcome — a 1430.0% case-fatality figure calculated directly from the underlying FDA records rather than from external mortality studies. The mean age at time of reporting is 11.3 years, with an average recorded body weight of 467.8 kg (1031.5 lbs). These figures reflect the voluntary reporting pool only and should be read alongside breed popularity, veterinary access, and owner awareness — all of which shape how many events ever reach the FDA.
The most frequently reported clinical signs for Lusitano are INEFFECTIVE, GASTRIC ULCER(S) (4 reports), Fever (3 reports), Cough (2 reports), together capturing a substantial share of the top-reaction traffic seen in this breed's record. On the product side, Omeprazole appears in 6 reports and is the single most-referenced drug, followed by Ceftiofur Crystalline Free Acid (2) and Detomidine Hydrochloride (2). Counts like these surface which therapeutic classes dominate the reporting stream — useful context when comparing reactions across breeds of the same horse species.
Outcome coding on the 14 reports with a recorded status is dominated by Ongoing (42.9% of coded outcomes). Annual submission volume ranges from 2,014 to 2,025 reports across the 9 years on file, indicating the reporting trend is shaped as much by awareness cycles as by underlying clinical events. Because FDA adverse event reports describe correlation rather than causation, these numbers are most useful as a signal of where to ask further questions with a veterinarian — not as a standalone risk score for any individual horse.
Understanding Lusitano Adverse Event Data
Lusitano has 14 adverse event reports on file. Lower report volumes may reflect a less common breed, lower reporting rates, or genuinely fewer adverse events.
The 1430.0% death rate is above average, though this statistic should be interpreted cautiously. Death reports may be overrepresented because serious outcomes are more likely to be reported than mild reactions.
The most frequently referenced drug in adverse reports is Omeprazole, appearing in 6 reports. This may indicate widespread use of the medication rather than a specific safety concern for Lusitano.
