Avitron is UNAHCO’s injectable antibiotic combination, pairing Thiamphenicol and Oxytetracycline with the corticosteroid Dexamethasone.

What Is Actually In It

UNAHCO’s page names three ingredients with no stated amounts: Thiamphenicol and Oxytetracycline, two antibiotics, and Dexamethasone, a corticosteroid used for inflammation rather than infection. These names are transcribed exactly as UNAHCO states them, and no amount is invented for any of them since none is given.

What the Label Says It Is For

UNAHCO’s label states Avitron treats infections caused by Thiamphenicol-Oxytetracycline combination-sensitive organisms, and separately indicates it for inflammation, which is the role Dexamethasone plays in the formulation. That is the manufacturer’s own claim, reproduced above.

Forms It Comes In

Avitron is sold as an injectable liquid, given intramuscularly. UNAHCO’s dosage of 0.1 mL per kilogram of body weight for 3 consecutive days is quoted verbatim in the box above; this body text does not repeat, convert, or adjust that figure.

Withdrawal Period

UNAHCO does not publish a withdrawal period for Avitron. Absence of a published figure is not the same as a zero-day withdrawal, and it is not treated as one here.

What This Page Does Not Tell You

This page transcribes what UNAHCO publishes about Avitron. It does not tell a reader whether a bird’s infection is actually sensitive to this antibiotic combination, or whether the inflammation being treated has an underlying cause that needs separate attention. Take that question, and any question about injection technique, to a veterinarian, an agrivet, or the local agriculture office.
