> **重要安全警告**:Ifosfamide 是一種強效化療藥物,具有引發嚴重副作用的高風險。通常作為試驗性治療使用。 - **處理注意事項**:此藥物會經由寵物的體液排出。**在治療後至少 24 小時內,請避免直接接觸寵物的唾液或尿液**。清理排泄物時請戴上手套。 - **副作用**:密切觀察是否有感染、出血、嘔吐或神經系統變化(如意識混亂、極度嗜睡)的跡象。 - **住院需求**:治療過程需要長時間的靜脈輸液,並搭配額外的水分與保護性藥物,以保護膀胱與腎臟。
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。

給藥方式
可能的副作用
- Myelosuppression (neutropenia at 5-7 days, potentially delayed to 14-21 days; thrombocytopenia)
- Hemorrhagic cystitis (bladder epithelial damage)
- Nephrotoxicity (proximal and distal tubular damage, electrolyte abnormalities)
- Volume overload and pulmonary edema (secondary to required saline diuresis)
- Neurotoxicity (somnolence, confusion, coma, encephalopathy)
- Gastrointestinal effects (nausea, vomiting, anorexia)
- Hypersensitivity reactions
- Alopecia
- Abnormal liver function tests
注意事項與禁忌
- Hypersensitivity to ifosfamide
- Severely depressed bone marrow function
- Active hemorrhagic cystitis
- Because of its toxicity, ifosfamide should only be used by clinicians experienced with cytotoxic agents. Must be used in conjunction with mesna and saline diuresis to reduce the risk of hemorrhagic cystitis and nephrotoxicity. Use with extreme caution in patients with impaired renal function or preexisting cardiac disease (due to volume overload risk). Handle and dispose of as a hazardous cytotoxic drug. FDA Category D for pregnancy (teratogenic and fetotoxic).
藥物相互作用
- Benzodiazepines (diazepam, chlordiazepoxide, oxazepam): May increase concentrations of active ifosfamide and increase toxicity (demonstrated in mice; clinical significance in veterinary patients undetermined)
- Cisplatin: Ifosfamide may enhance cisplatin-induced ototoxicity and nephrotoxicity
- Myelosuppressive drugs (chloramphenicol, flucytosine, amphotericin B, colchicine, other antineoplastics): Additive myelosuppression
