Fish Flex Forte (Cephalexin 500mg) is for use in aquariums for the treatment of
bacterial activity. Cephalexin is a cephalosporin antibiotic and acts by inhibiting
the synthesis of bacterial cell wall, leading to cell death. Cephalexin is active
against both gram-positive and gram-negative bacteria. Resistance can develop
among some gram-negative rods (e.g., E. coli).
Fish: Add one capsule into aquarium for each 20 gallons of water. Repeat
in 24 hours. It is suggested that a partial water change be made between treatments.
While treatment duration depends on the type and severity of infection, it is
recommended that extended baths in the medication continue for a minimum of
5 days and for not more than 10 days. Discontinued treatment if no improvement
is noted within 5 days.
Dogs and Cats: 10-30 mg/Kg (5-14 mg/lb) every 6-8 hours orally. Fish
Flex is commonly given in off-label use to small animals.
Used to treat skin infections, urinary tract infections, wound infections,
and respiratory infections.
Contraindications: Sensitivity to cephalosporins.
Not for human use.
