Tylosin injection is a macrolide antibiotic primarily used to treat bacterial and mycoplasma infections in swine, poultry, and other animals. The specific dosage should be adjusted based on the animal species, weight, and severity of the infection. The recommended dose is 10-20 mg/kg body weight, injected intramuscularly once daily for 3-5 days. Details are as follows:
Indications and Dosage
Swine: For the treatment of mycoplasma pneumonia and contagious pleuropneumonia, use 10-15 mg/kg body weight once daily.
Poultry: For the treatment of chronic respiratory diseases, use 15-20 mg/kg body weight, diluted if necessary.
Other animals (such as cattle and sheep): Refer to the veterinary drug package insert or veterinarian's instructions for dosage adjustments.
Injection Method
Injection Site: Select areas with abundant muscle mass (such as the neck and buttocks), avoiding areas with dense blood vessels and nerves.
Procedure: Disinfect the needle and injection site before injection. Inject slowly to minimize local irritation. Frequency and Treatment Duration: Once daily, generally for 3 consecutive days. For severe infections, the duration of use may be extended to 5 days. Avoid exceeding the duration of treatment.
Precautions
Allergic Reactions: Some animals may experience local redness, swelling, or allergic reactions. Immediately discontinue the drug and seek medical attention.
Incompatibility: Avoid use with β-lactams (such as penicillin) and lincomycin.
Withdrawal Period: For pigs and poultry, a 7-14-day withdrawal period is required to ensure that drug residues meet safety standards.
Storage: Store in a cool, dark place (below 25°C). Use as soon as possible after opening.
Use in Special Populations
Pregnant Animals: Use with caution in late pregnancy; assess the risk under veterinary guidance.
Young Animals/Poultry: The dosage may be reduced appropriately to avoid drug accumulation.
Tylosin is a prescription drug and should be used strictly in accordance with veterinary instructions and the product package insert. If an animal develops severe symptoms such as difficulty breathing or high fever, or if symptoms persist after medication, seek medical attention and adjust the treatment plan promptly.
