COP Chemotherapy Protocol
別名: COP Protocol, High-dose COP
Your pet is undergoing a combination chemotherapy protocol called **COP**. * **Safe Handling:** Chemotherapy drugs are excreted in your pet's urine and feces. Wear disposable gloves when handling their waste or cleaning up accidents for at least 48 hours after treatment. Wash hands thoroughly. * **Medication Administration:** Never crush or split chemotherapy tablets. * **What to watch for:** Monitor closely for signs of infection (lethargy, fever), gastrointestinal upset (vomiting, diarrhea, loss of appetite), or **blood in the urine**. * If you notice blood in the urine, stop the cyclophosphamide immediately and contact your veterinarian, as this may indicate bladder irritation (haemorrhagic cystitis).
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。

注意事項與禁忌
- Severe neutropenia (< 2 x 10^9/L)
- Pre-existing haemorrhagic cystitis
- Known MDR1 mutation (requires extreme caution/dose adjustment for vincristine)
- > **Vesicant Warning:** Vincristine is a vesicant. IV catheters must be placed in all cases, and ONLY catheters placed by a clean 'first-stick' should be used. > **Myelosuppression:** Discontinue cyclophosphamide if neutrophil count decreases to < 2 x 10^9/L. Check weekly and do not resume until > 3 x 10^9/L. If neutropenia recurs, decrease dose by 10-25%. > **MDR1 Mutation:** Certain breeds (generally Collie type) are very sensitive to vincristine due to the MDR1 mutation; commercial testing is highly recommended prior to treatment. **Clinical Pearl:** GI protectants (e.g., Omeprazole 1 mg/kg q12-24h or Ranitidine with sucralfate) are recommended for the first 21 days of the protocol.
藥物相互作用
- Cimetidine: Inhibits hepatic cytochrome P450 enzyme pathway, potentially altering the metabolism and increasing toxicity of chemotherapeutics.
