Topiramate
別名: Topamax, Topiragen, Epitomax, Topamac, Topimax
> **Important**: Never stop this medication abruptly, as it can trigger severe "rebound" seizures. Always consult your veterinarian before changing the dose. * **Administration**: Can be given with or without food. If your pet experiences stomach upset, try giving the medication with a small meal. * **Behavioral Changes**: Watch for signs of irritability, sedation, or loss of appetite, especially when starting the medication or increasing the dose. Contact your vet if these occur. * **Seizure Diary**: Keep a detailed log of any seizures (date, time, duration, and severity) to help your veterinarian determine if the medication is working. * **Commitment**: Because this drug is processed very quickly in dogs, you may need to administer it 2 to 3 times a day exactly as prescribed. * **Expectations**: The clinical use of this agent is relatively 'investigational' in veterinary patients, and it is often used when other medications have failed.
