Long-acting injectable oxytetracycline for susceptible bacterial infections in horses and cattle; respiratory disease, pinkeye, anaplasmosis. Long-acting injectable oxytetracycline (LA-200 formulation). Mechanism: bacteriostatic tetracycline — reversibly binds 30S ribosomal subunit → blocks aminoacyl-tRNA attachment → inhibits bacterial protein synthesis. 200 mg/mL formulation in polyvinylpyrrolidone vehicle provides 3–5 day tissue levels. Broad spectrum. Key information Oxytetracycline long-acting. Refrigerate. Administer deep IM — IV or SC causes tissue necrosis. Cattle withdrawal: 28 days beef, 96 hours milk. Do not use in veal calves. High risk of injection site reactions.

IV (horses): dilute in sterile saline (minimum 1 mg/mL); infuse slowly over 30–60 min. Never inject IM in horses — tissue necrosis. SQ in cattle: inject at recommended volume per site; rotate sites. Store at room temperature; protect from light. If a dose is missed This medication is administered by a veterinarian or veterinary staff in a clinical setting. Missed doses are managed by your veterinary team — contact your veterinarian to reschedule.

Injection site reactions: significant tissue irritation, swelling, necrosis at IM injection sites (200 mg/mL — severe in horses; use with care). GI: diarrhea, anorexia. Photosensitivity. Renal/hepatic toxicity. Superinfection. Withdrawal times for food animals.

For animals See oxytetracycline. IM injection in horses: severe tissue necrosis with high-concentration formulations — use SQ in cattle, IV in horses (diluted). Observe food animal withdrawal times for milk and meat. Use with caution in pregnant animals. For people handling this medication Wear gloves when handling. Wash hands thoroughly with soap and water after handling. Oxytetracycline injectable — Keep out of reach of children. Pregnant women and women of childbearing age should avoid contact. Tetracyclines affect fetal bone/tooth development. Wear gloves. Avoid skin contact.

Contact your veterinarian. Oxytetracycline overdose causes GI signs and kidney damage. Injection site tissue necrosis possible with IM overdose.
