i. Special precautions for use in animals
During anaesthesia, the fish must be closely monitored. A number of factors
influence the efficacy and safety of the product, including concentration of
the drug in water, duration of exposure, temperature, oxygen and density of
biomass. Hence it is recommended to test the selected drug concentration
and exposure time is conducted with a small group of representative fish
before large numbers are medicated, particularly when water temperature is
at the upper or lower ends of the normal temperature ranges for the species
being treated. The product should be dissolved in water of the same
composition and characteristics as that to which the fish are accustomed.
To minimise damage and loss when medicated the level of sedation should
allow fish to maintain their equilibrium and swimming position.
ii. Special precautions to be taken by the person administering the
medicinal product to animals
Benzocaine may cause hypersensitivity (allergy) following ingestion or
contact with the skin or mucosa. In rare cases, benzocaine may cause
methaemoglobinaemia (excessive methaemoglobin in the blood) in people
who are hypersensitive. Cyanosis (blue skin or lips) may occur as a result
of excessive methaemoglobin concentrations.
Avoid handling this product if you know you are sensitised to benzocaine, or
if you have been advised not to work with such preparations.
As an anaesthetic, benzocaine may cause adverse reactions, including
nervous, respiratory and cardiovascular alterations. This includes direct
contact with skin, which can cause local anaesthesia and prolonged
exposure may cause dermatitis.
This veterinary medicinal product also contains DMSO as an excipient,
which may be irritant to the skin.
Avoid contact with the eyes, skin and clothing.
Do not eat, drink or smoke when handling the product or the anaesthetic
bath.
Always wear impermeable gloves when handling the product and preparing
stock solution or the anaesthetic bath.
In case of contact with the eyes, flush immediately with plenty of clean
water. In case of skin contact, wash the exposed area immediately with

plenty of water. Remove contaminated clothes immediately. If you develop
symptoms following exposure, you should seek medical advice and show
the package leaflet or the label to the doctor.
In case of accidental ingestion, seek medical advice immediately and show
the package leaflet / label to the doctor. Vomiting may be induced; activated
charcoal may be administered.
Foetal deaths may occur following administration of benzocaine in human
beings.
Pregnant women should be extra careful to avoid exposure if handling the
product.
Wash hands thoroughly after use.
iii. Other precautions
In order to protect the environment, used solution must be transferred to a
holding tank filled with water with subsequent controlled release for dilution in
the effluent to be discharged from the facility. See section 6.6.
