Special warnings for each target species
Special precautions for use
(i) Special precautions for use in animals
Use of the product should be based on susceptibility testing of the bacteria isolated from the animal. If this is not possible, therapy should be based on local epidemiological information.
For administration by the intramuscular route only.
Use different injection sites for repeat injections.
The efficacy data do not support the use of tylosin for the treatment of bovine mastitis caused by Mycoplasma spp.
(ii) Special precautions to be taken by the person administering the veterinary medicinal product to animals
Care should be taken to avoid accidental self-injection.
If accidental self-injection occurs, seek medical attention immediately.
In the event of accidental skin contact, wash thoroughly with soap and water. In case of accidental eye contact, flush the eyes with plenty of clean, running water.
Wash hands after use.
Tylosin may induce irritation. Macrolides, such as tylosin, may also cause hypersensitivity (allergy) following injection, inhalation, ingestion or contact with skin or eye. Hypersensitivity to tylosin may lead to cross reactions to other macrolides and vice versa. Allergic reactions to these substances may occasionally be serious and therefore direct contact should be avoided.
Do not handle the product if you are allergic to ingredients in the product.
If you develop symptoms following exposure, such as skin rash, you should seek medical advice and show the physician this warning. Swelling of the face, lips and eyes or difficulty in breathing are more serious symptoms and require urgent medical attention.
(iii) Other precautions
Blemishes may occur at the site of injection and can persist for up to 21 days following administration.
Adverse reactions (frequency and seriousness)
Possible adverse reactions attributed to the product when used as recommended and their frequency are: In very rare cases the following have been observed;
- swelling/inflammation at the site of injection,
- vulvular swelling in cattle,
- oedema of the rectal mucosa, partial anal protrusion (‘rosebudding’)
- erythema and pruritus in pigs.
- Anaphylactic shock and death.
Use during pregnancy, lactation or lay
No adverse effects to tylosin have been seen in fertility, multi-generation or teratology studies.
Interaction with other medicinal products and other forms of interaction
Amounts to be administered and administration route
Tylan should be given by intramuscular injection at the following dose rates:
Cattle and calves: 4 to 10 mg per kg bodyweight daily.
Pigs: 2 to 10 mg per kg bodyweight daily.
If there is no response to treatment in 3 days, diagnosis and treatment should be reassessed.
The maximum injection volume for cattle is limited to 15ml per injection site.
In pigs do not administer more than 5 ml per injection site.
To ensure the correct dosage, bodyweight should be determined as accurately as possible to avoid under dosing.
Overdose (symptoms, emergency procedures, antidotes), if necessary
Pigs and calves: Intramuscular injection of 30mg/kg bodyweight per day (three times maximum recommended dose) for five days produced no adverse effects.
The LD50 for subcutaneous injection of tylosin in mice is estimated to be >2500mg/kg bodyweight.
Pigs: Meat and offal - 16 days
Cattle: Meat - 28 days
Cattle: Milk - 108 hours
With cows milked twice daily, milk for human consumption may be taken only from 108 hours i.e. at the 9th milking) after the last treatment. With other dosing routines, the basis of the veterinary surgeons advice should be that milk may be taken for human consumption only after the same period from the last treatment (i.e. with three times a day milking, milk for human consumption may be taken only from 108 hours i.e. at the 14th milking).
