Contact your veterinarian immediately if your pet has a seizure, extreme behavioral changes (e.g., aggression), severe and/or persistent vomiting, or complete loss of appetite.
Notify your veterinarian if your pet experiences any of the effects described above, or if you notice any other side effects that are persistent or troublesome.
If you notice anything unusual, please consult your veterinarian.
Precautions
Do NOT discontinue this medication abruptly or make any changes to the prescribed dosing schedule without consulting your veterinarian first. Do not miss any follow-up visits, as bloodwork and/or an exam may be required to monitor your pet’s progress.
