ADMINISTRATION

• Direct Oral Administration: The most common method involves using a drenching gun or an oral dosing syringe to place the specified amount of liquid into the back of the animal’s mouth, over the tongue. This technique is intended to help prevent the animal from spitting out the medication and aims to ensure it is swallowed correctly.
• Mixing with Water/Feed (Less Common): While some formulations might be suitable for mixing with a small quantity of water or feed, direct administration is generally favored for better absorption and to help ensure the entire dose is consumed.
