Reporting adverse events is important. It allows continuous safety monitoring of a
veterinary medicinal product. Reports should be sent, preferably via a
veterinarian, to either the marketing authorisation holder or its local
representative or the national competent authority via the national reporting
system. See the package leaflet for respective contact details.
None.

Special precautions for use in animals
Animals with acute infections may have a reduced feed intake and should be
treated with a suitable injectable veterinary medicinal product first.
Due to likely variability (time, geographical) in susceptibility of bacteria for tylosin,
bacteriological sampling and susceptibility testing are recommended.
Inappropriate use of the veterinary medicinal product may increase the
prevalence of bacteria resistant to tylosin and other macrolides.
Special precautions to be taken by the person administering the veterinary
medicinal product to animals
Tylosin may induce irritation. Macrolides, such a 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.
Personal protective equipment, consisting of overalls, safety glasses, impervious
gloves, and either a disposable half mask respirator conforming to European
Standard EN149 or a non-disposable respirator to European Standard EN140
with a filter to EN143 should be worn during preparation of the medicated feed.
Wash hands after use.
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.
Do not handle the veterinary medicinal product if you are allergic to ingredients
in the veterinary medicinal 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.
