Zeflexin is Univet’s cephalexin water-soluble antibiotic powder.
What Is Actually In It
Zeflexin contains cephalexin, which Univet’s label prints as a 20% w/w water-soluble powder. That percentage is transcribed exactly as the manufacturer states it.
What the Label Says It Is For
Univet’s label states Zeflexin is “for prevention and treatment of infections caused by Cephalexin-sensitive organisms,” and describes it as “potent against fowl cholera and infectious coryza.” Both phrases are the manufacturer’s own wording, quoted rather than adopted as an assessment from this page. Fowl cholera and infectious coryza can present with overlapping respiratory symptoms that are difficult to tell apart without testing.
Forms It Comes In
Zeflexin is a water-soluble powder. Univet’s dosage, quoted in the fact box above, is to mix 6 grams or 1 teaspoon into 1 gallon of water, given twice a day for 3 to 5 days. That figure is quoted directly from the manufacturer’s page.
Withdrawal Period
Univet does not publish a withdrawal period for Zeflexin, for meat or eggs. That absence is not treated as a zero-day withdrawal here.
What This Page Does Not Tell You
This page reproduces what Univet publishes about Zeflexin: a confirmed cephalexin concentration, a susceptibility-based indication naming two specific diseases in the manufacturer’s own words, a water-mixing dosage, and no published withdrawal period. It does not confirm whether a flock’s respiratory symptoms are fowl cholera, infectious coryza, or something else. See Antibiotics for Chickens in the Philippines, and get a veterinarian’s assessment before treating.
