Amprol (Amprolium, Corid) is used to treat Coccidiosis
, caused by infection with Eimeria
species (Coccidia). It is of the chemical group thiamine analog, which works by competitively inhibiting the active transport of thiamine, which is what the Coccidia are sensitive to. If birds receive too much of this drug it can cause thiamine deficiency.

40 - 250 mg/kg feed or 1.25 cc/L in drinking water, daily for 3-5 days. No other source of drinking water should be available to the birds during this time.
Egg Withdrawal Period: No withdrawal period is needed.
