Carbamazepine
別名: Tegretol, Carbatrol, Epitol, Equetro
Your veterinarian has prescribed carbamazepine for your pet. Please read the following carefully: * **Off-Label Use:** This medication is used "off-label" in veterinary medicine. It is used infrequently, and your veterinarian has prescribed it based on your pet's specific behavioral or neurological needs. * **Strict Schedule:** It is crucial to give this medication exactly as prescribed. Because animals process this drug very quickly, missing a dose can lead to a loss of effectiveness. It often requires frequent administration. * **What to Watch For:** Monitor your pet for signs of lethargy, unsteadiness (ataxia), or gastrointestinal upset (vomiting, loss of appetite). > **Important:** Report any unusual behavior, severe vomiting, or yellowing of the eyes/gums (jaundice) to your veterinarian immediately, as these could be signs of liver stress or adverse reactions.
劑量必須由獸醫按你寵物的個別情況決定。切勿在沒有獸醫指導下給予人類藥物或其他寵物的處方藥。
用途
- For photic head shaking
- As a psychotherapeutic agent
給藥方式
可能的副作用
- Sedation and lethargy
- Ataxia (unsteadiness)
- Gastrointestinal upset (vomiting, anorexia)
- Hepatotoxicity (elevated liver enzymes)
- Blood dyscrasias (rare but possible bone marrow suppression)
注意事項與禁忌
- Patients receiving MAO Inhibitors (e.g., selegiline) within the past 14 days
- Patients with a history of bone marrow depression
- Known hypersensitivity to carbamazepine or tricyclic antidepressants
- Use with extreme caution due to extensive drug interactions (it is a potent inducer of hepatic enzymes). In dogs, it rapidly induces its own metabolism (autoinduction), making long-term therapeutic dosing difficult. May interfere with thyroid function tests (decreased values) and some pregnancy tests, though veterinary significance is unclear.
