How do I give this medication?
•Give the first dose 30 to 60 minutes before the expected noise event.
•IMPORTANT: This medication is absorbed through the gums and should NOT be swallowed. It may not work if it is swallowed.
•To administer the medication:
‐Hold the syringe so that you can see the dot markings.
‐Hold the plunger with one hand. With the other hand, twist the dosing ring along the plunger until the number of dots shown between the dosing ring and the barrel of the syringe matches the prescribed dose. The side of the ring-stop closest to the barrel should be in line with the black line on the plunger.
‐Hold the syringe barrel and pull, don’t twist, the cap off the syringe and set it aside. The cap is very tight and requires a strong pull.
‐Place the syringe tip between your dog’s cheek and gum and press the plunger until the ring causes it to stop, applying the medication along the gumline. If your dog’s prescription is for more than 6 dots, divide the dose between both sides of the mouth.
‐Recap the syringe and place it back in the box. Remove and discard gloves.
•If your veterinarian instructed you to give multiple doses during a noise event:
