Drug Type: Antibiotic


Sulfadimethoxine (brand name Albon®) is a sulfonamide antibiotic (a type of "sulfa drug") used primarily to treat coccidiosis in poultry. It can be given as a standalone medication or combined with ormetoprim.

Egg Withdrawal Period: Sulfadimethoxine should not be given to poultry producing eggs intended for human consumption in any country, due to the lack of studies on the duration of residues in the eggs of treated hens.

Caution: Sulfadimethoxine can precipitate in urine forming crystals or even stones, leading to kidney damage and gout. This is typically a problem with prolonged use or acidified urine. Sulfa drugs should not be given to birds with liver or kidney problems.
