Usage
Interceptor Plus should be administered as directed by your veterinarian. Please consult your veterinarian before making any changes or discontinuing the prescribed dosing schedule.

If a dose is missed: Give Interceptor Plus immediately to resume monthly dosing and notify your veterinarian. Do not give more medication than prescribed or two doses at once.
If multiple doses have been missed, consult your veterinarian prior to restarting the monthly dosing schedule. If you have questions about your pet’s prescribed dosing schedule (e.g., timing, interval), please contact your veterinarian.

Manufacturer Directions for Use*:
You can give Interceptor Plus to your dog by hand or by adding it to a small amount of dog food. Administer the chewable in a manner that encourages your dog to chew, rather than swallow without chewing. If your dog normally swallows treats whole, you may break the chewable into pieces and feed them to your dog. Make sure that your dog consumes the complete dose and observe your pet for a few minutes after the administration to ensure that no part of the dose is lost or rejected. If you suspect that any of the dose has been lost, redosing is recommended. Consult your veterinarian regarding the need for year-round administration of Interceptor Plus. To help you remember to dose monthly, each box contains stick-on labels for your calendar.

*Additional information may be provided within the manufacturer’s full Prescribing Information. Always follow the specific instructions provided by your veterinarian regarding your pet's care.
