Special precautions for use in animals
Before treating with the veterinary medicinal product, the integrity of the tympanic
membrane must be verified.
Use of the veterinary medicinal product should be based on susceptibility testing of
the bacteria and/or fungi isolated from the animal. If this is not possible, therapy
should be based on local (regional) epidemiological information about susceptibility
of the target pathogens.
Official and local antimicrobial policies should be taken in to account when the
veterinary medicinal product is used.
Heavy reliance on a single class of antibiotic may result in the induction of resistance
in a bacterial population.
It is prudent to reserve the fluoroquinolones for the treatment of clinical conditions
which have responded poorly, or are expected to respond poorly, to other classes of
antibiotics.
Quinolone class drugs have been associated with cartilage erosions in weight-
bearing joints and other forms of arthropathy in immature animals of various species.
The use of the product in young animals is not recommended.
Prolonged and intensive use of topical corticosteroid preparations is known to trigger
local and systemic effects, including suppression of adrenal function, thinning of the
epidermis and delayed wound healing.
Avoid contact with eyes in animals. In case of accidental contact, rinse thoroughly
with water.
Special precautions to be taken by the person administering the veterinary medicinal
product to animals
People with known hypersensitivity (allergy) to (fluoro)quinolones, (cortico)steroids or
antifungals and to other ingredients in the veterinary medicinal product should take
care to avoid contact with the veterinary medicinal product during administration.
Avoid contact of the skin and eyes with the veterinary medicinal product. In case of
accidental spillage onto skin or eyes, rinse the affected area with large amounts of
water.
Take care to avoid accidental ingestion. In case of accidental ingestion, seek medical
advice immediately and show the leaflet or the label to the physician.
Wash hands after use.
