To evaluate IV iron sucrose safety and impact on hematologic and iron indices in healthy cats.


5 healthy research cats.


Cats were administered iron sucrose (0.5 mg/kg, IV) over 30 minutes. Monitoring for acute reactions (temperature, heart rate, respiratory rate, and blood pressure) was performed every 5 minutes during injection and every 15 minutes for an additional hour. Baseline, 24-hour, and 1-, 2-, and 3-week postinjection measurements of CBC with reticulocyte indices, iron panel (ferritin, total iron-binding capacity, and iron), calculated transferrin saturation (TSAT), and serum amyloid A (SAA) concentration were performed.


No cat experienced an acute drug reaction. SAA concentration was increased at 24 hours versus baseline. TSAT and ferritin decreased over time, with 3 cats developing concurrent functional iron deficiency (FID) and anemia. Hct (Spearman correlation [r s] = 0.805), hemoglobin (r s = 0.770), and reticulocyte hemoglobin content (r s = 0.581) correlated with TSAT.


IV iron sucrose was well tolerated in healthy cats but was associated with transient increase in the systemic inflammatory marker SAA. Efficacy evaluation of dose based on iron deficit is needed in sick cats. Despite cumulative blood draw volume below recommended limits, anemia and FID were observed, which has important implications for experimental designs and serial hematologic monitoring. Further evaluation of inflammatory response to IV iron sucrose administration is warranted.

A 5-year-old 22.7-kg (49.9-lb) spayed female Boxer cross was presented to a primary care veterinarian for evaluation of multiple dermal nodules on both pinnae (Figure 1) Approximately 2 weeks earlier, the dog had been examined because of a suspected interdigital foreign body on the left forelimb. Sterile exploration of the lesion revealed no foreign material. Cephalexin (22 mg/kg [10 mg/lb], PO, q 12 h for 10 days) was prescribed. The dermal nodules began emerging several days after initiation of cephalexin administration. The dog was also maintained on diphenhydramine (2.2 mg/kg [1 mg/lb], PO, q 8 to 12
