您的獸醫師為您的寵物開立了卡馬西平（Carbamazepine）。請仔細閱讀以下資訊： * **標示外使用（Off-Label Use）：** 此藥物在獸醫學中屬於「標示外使用」。它並不常用，您的獸醫師是根據您寵物特定的行為或神經系統需求而開立的。 * **嚴格遵守給藥時間：** 務必完全按照指示給藥。因為動物代謝這種藥物的速度非常快，漏服一次可能會導致藥效喪失。它通常需要頻繁給藥。 * **觀察事項：** 觀察您的寵物是否有嗜睡、步態不穩（共濟失調）或腸胃不適（嘔吐、食慾不振）的跡象。 > **重要提示：** 如果發現任何異常行為、嚴重嘔吐或眼睛/牙齦發黃（黃疸），請立即向您的獸醫師報告，因為這些可能是肝臟壓力或不良反應的徵兆。
劑量必須由獸醫依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
PO
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.
