Tetroxy L.A. 200 mg/ml Oxytetracycline Solution for Injection — SPC Details

Source: VMD Summary of Product Characteristics (SPC). Last updated 27 Mar 2026.

Tetroxy L.A. is indicated in the treatment and control of diseases caused by or
associated with organisms sensitive to Oxytetracycline in cattle, sheep and
pigs.

Tetroxy L.A. is administered by deep intramuscular injection at the rate of 1 ml
per 10kg bodyweight which is equivalent to 20mg Oxytetracycline per kg.
It is recommended that the following amounts of Tetroxy L.A. at one site should
not be exceeded:
Cattle and Sheep - 10 ml
Pigs 5 ml
Pigs under 10 kg maximum dose of 1 ml

Revised: January 2024
AN: 01919/2023
Effective blood levels are maintained for up to 72 hours in cattle and 48 hours in pigs
and sheep.
Because of the sustained blood levels attained at the above dosage rates with
Tetroxy L.A., this is a single dose treatment.

Not recommended for cats, dogs, horses and donkeys.

Occasional local reaction of a transient nature may occur at the site of injection.

Prolonged use of anti-infectives may result in super infection by non-
susceptible organisms. Photodermatitis may occasionally occur after treatment
under strong exposure to sunlight.

Revised: January 2024
AN: 01919/2023
