AMPROL (amprolium) 20% Soluble Powder is intended for the treatment of
coccidiosis in growing chickens, turkeys and laying hens.

USE DIRECTIONS: Give amprolium at the 0.012% level (10 oz AMPROL 128 20%
Soluble Powder per 128 Gallons) as soon as coccidiosis is diagnosed and continue for three to five days. (in severe outbreaks, give amprolium at the 0.024% level.)
Continue with 0.006% amprolium medicated water for an additional 1 to 2 weeks.

No other source of drinking water should be available to the birds during this time.
Use as the sole source of amprolium.

There is no egg or meat withdrawal time for Amprolium in poultry feed. The FDA has deemed it safe to eat the eggs or meat from birds that have consumed it.
​
Contrary to popular belief, Amprolium is not an antibiotic. It is a thiamin blocker, and the cocidia parasite needs thiamin to multiply in the gut of a bird.
