🔍 1. What Is Orbifloxacin?

🎯 2. FDA‑Approved & Off‑Label Uses

• Dogs: FDA-approved for urinary tract infections, wounds, abscesses, and skin infections :contentReference[oaicite:4]{index=4}.

💊 3. Dosing & Administration

• Dogs: 2.5–7.5 mg/kg PO once daily (≈1.1–3.4 mg/lb) depending on infection severity :contentReference[oaicite:6]{index=6}.
• Cats: 7.5 mg/kg (3.4 mg/lb) PO once daily; do not exceed this dose due to retinal risk :contentReference[oaicite:7]{index=7}.
• Available as tablets and tasty malt-flavored suspension; best given on an empty stomach—if GI upset occurs, give with a small, non-dairy snack :contentReference[oaicite:8]{index=8}.

⚠️ 4. Side Effects & Safety Risks

• GI upset: vomiting, diarrhea, nausea are the most common effects :contentReference[oaicite:10]{index=10}.
• Cartilage defects: risk of arthropathy in growing dogs; avoid use in puppies under breed-specific age thresholds :contentReference[oaicite:11]{index=11}.
• Retinopathy: high doses may cause reversible retinal changes or blindness in cats :contentReference[oaicite:12]{index=12}.
• Neurologic: rare effects include tremors, incoordination, seizures—especially in pets with CNS disease :contentReference[oaicite:13]{index=13}.

🚫 5. Contraindications & Precautions

• Safety not established in pregnant or nursing animals—use only if benefits outweigh risks :contentReference[oaicite:17]{index=17}.

🔄 6. Drug Interactions

• Avoid with dairy, antacids, or supplements containing calcium, magnesium, iron, aluminum, zinc—these reduce absorption :contentReference[oaicite:18]{index=18}.
