If your dog is taking phenobarbital for seizures but continues to experience them, you’re likely feeling worried and frustrated. This is a common concern among dog owners, and understanding the reasons why seizures may persist despite medication is crucial. This article addresses this issue, offering guidance and potential solutions to help manage your dog’s seizures and improve their quality of life.
Phenobarbital is a commonly prescribed anticonvulsant for dogs, often the first line of defense against seizures. However, it isn’t a one-size-fits-all solution. Several factors can contribute to breakthrough seizures while on medication. Let’s explore these factors and discuss what you can do.
Understanding Phenobarbital and Seizure Control
Phenobarbital works by depressing the central nervous system, reducing the excitability of neurons that trigger seizures. It’s generally effective, but some dogs may require higher doses or additional medications to achieve optimal control. It’s also important to remember that phenobarbital doesn’t cure epilepsy, but rather manages the frequency and severity of seizures.
Reasons for Breakthrough Seizures
Several factors can contribute to breakthrough seizures despite phenobarbital therapy. These include:
- Incorrect Dosage: Your dog may require a dosage adjustment, either higher or lower, to achieve optimal blood levels of phenobarbital. Regular monitoring of these levels is essential.
- Drug Interactions: Other medications your dog is taking may interfere with phenobarbital’s effectiveness. Discuss all medications, supplements, and even dietary changes with your veterinarian.
- Underlying Health Issues: An undiagnosed or untreated health condition, such as liver disease or a brain tumor, could be contributing to the seizures.
- Phenobarbital Resistance: In some cases, dogs can develop resistance to phenobarbital over time, requiring a change in medication or the addition of a second anticonvulsant.
- Cluster Seizures: Some dogs experience clusters of seizures, where multiple seizures occur close together, even with medication.
Veterinarian Examining Dog Having Seizures
What to Do If Your Dog is Still Having Seizures
If your dog is experiencing seizures despite being on phenobarbital, it’s essential to contact your veterinarian immediately. They will likely recommend the following:
- Bloodwork: To check phenobarbital levels and assess liver function.
- Medication Adjustment: Based on the bloodwork results, your vet may adjust the phenobarbital dosage.
- Additional Testing: Further diagnostic tests, such as MRI or CT scans, may be necessary to rule out underlying health issues.
- Adding Another Medication: Your vet may consider adding a second anticonvulsant, such as potassium bromide or levetiracetam, to improve seizure control.
Managing Seizures at Home
While working closely with your veterinarian is crucial, there are also steps you can take at home to help manage your dog’s seizures:
- Keep a Seizure Diary: Record the date, time, duration, and any unusual behaviors observed before, during, and after each seizure. This information is invaluable for your veterinarian.
- Create a Safe Environment: Remove any potential hazards from your dog’s environment, such as sharp objects or furniture they could injure themselves on during a seizure.
- Stay Calm and Reassuring: During a seizure, remain calm and speak to your dog in a soothing voice. Do not attempt to restrain them.
- Monitor for Side Effects: Phenobarbital can cause side effects, such as increased thirst, urination, and appetite. Notify your veterinarian if you notice any unusual changes in your dog’s behavior.
Conclusion
Seeing your dog experience seizures is distressing, but there are options available. By working closely with your veterinarian, monitoring your dog’s condition, and implementing appropriate management strategies, you can help improve their quality of life and reduce the frequency and severity of their seizures. Remember, consistent communication with your vet is key to effectively managing seizures in dogs on phenobarbital.
