All poultry are classified as food producing animals. Sadly, there are comparatively few medicines authorised for use in these species compared to other pets. Therefore, the majority of medicines prescribed will be used on the veterinary cascade.
Examples of medication and warnings can be found below. All these medicines are regularly prescribed by the practice. All owners will be asked to give consent to their bird being prescribed medicines on the veterinary cascade. This covers all future off-licence medicine use, regardless of the product or the condition for which it is being used.

Use in birds: It is useful in birds with delayed crop emptying or showing signs of nausea.
Dose rates: Dose rates for this medicine are provided in numerous veterinary formularies.
Withdrawal period: Despite studies on pharmacokinetics in other species suggesting it is a short-acting and rapidly excreted, it is not authorised in food producing species so maximum withdrawals are applied. 28-day egg withdrawal, 56-day meat and offal withdrawal.
