Withdrawal period

Withdrawal period is the number of days from the last treatment of animals with a drug until the moment when the metabolic residues of the drug in the organs, milk, eggs are no longer harmful if used in human nutrition. Drugs have different withdrawal periods, which can vary depending on the type of animal or the tissue where the metabolic process of drug degradation occurs.

The information about the withdrawal period is provided by the veterinarian to the animal owner or printed on the treatment documents automatically if the withdrawal period is set in the Drug identification code of the drug. The data on the withdrawal period for a specific treatment can be found in the tab Service performed | Withdrawal period.

In this chapter, we have prepared a user case for you on how to set the withdrawal period information for each drug and review it during treatment, where the information appears. 

CASE DESCRIPTION Cattle were treated with antibiotics due to a bacterial infection. The withdrawal period for the antibiotic TRISULFON is not visible, as it has not yet been set.
