Carboplatin
Also known as: Paraplatin
Carboplatin is a potent chemotherapy drug used to treat your pet's cancer. While it is generally well-tolerated, there are important safety and care guidelines you must follow at home: * **Handling Waste:** Because the drug and its active byproducts are excreted in the urine for several days after treatment, **avoid direct contact with your pet's urine, feces, and vomit**. Wear disposable gloves when cleaning up accidents, and wash your hands thoroughly afterward. * **The "Nadir" Period:** Carboplatin temporarily lowers your pet's white blood cell count, making them more susceptible to infection. This low point (the nadir) typically occurs around **14 days after treatment in dogs** and **21 days in cats**. * **When to Call the Vet:** Monitor your pet closely during the nadir period. Contact your veterinarian immediately if your pet develops a **fever, severe lethargy, vomiting, or diarrhea**. * **Appetite & Nausea:** Mild nausea or loss of appetite may occur 2 to 4 days after the infusion. Your veterinarian may prescribe anti-nausea medications to keep your pet comfortable. * **Pregnancy Warning:** Pregnant women, nursing mothers, and immunocompromised individuals should avoid handling the pet's waste entirely.
Dosage must be set by your veterinarian for your specific pet. Never give human medication or another pet’s prescription without veterinary guidance.
What it is used for
- Antineoplastic
- Neoplastic diseases (All uses)
- Neoplastic diseases (Intrapleural/intraperitoneal)
- Adenocarcinoma
- Antineoplastic
- Neoplastic diseases (All uses)
- Neoplastic diseases (Intrapleural/intraperitoneal)
- Equine sarcoids
- Antineoplastic
How it is given
Possible side effects
- Bone marrow suppression (neutropenia, thrombocytopenia)
- Anorexia
- Vomiting (typically 2-4 days post-dose)
- Hepatotoxicity (elevated bilirubin and liver enzymes)
- Nephrotoxicity (less frequent than cisplatin)
- Neuropathies (rare)
- Ototoxicity (rare)
- Anaphylactoid reactions (rare)
- Hyperuricemia
Cautions & contraindications
- History of hypersensitivity to carboplatin or other platinum agents
- Severe bone marrow depression
- Pregnancy (fetotoxic and embryotoxic - Category D)
- **DO NOT give IM or SC.** Extreme caution is advised in patients with active infections, hearing impairment, or preexisting renal or hepatic disease. Patients with severe carboplatin-induced myelosuppression must recover their cell counts before additional therapy. **Equipment Warning:** Do not prepare, store, or administer using aluminum-containing needles or IV sets, as aluminum displaces platinum, causing a black precipitate and loss of potency.
Drug interactions
- Aminoglycosides: Potential for increased risk of nephrotoxicity or ototoxicity.
- Cisplatin: Patients previously treated with cisplatin have an increased risk of developing neurotoxicity or ototoxicity after receiving carboplatin.
- Myelosuppressive drugs: The leukopenic or thrombocytopenic effects secondary to carboplatin may be enhanced.
- Radiation therapy: Potential for increased hematologic toxicity.
- Vaccines: Live or killed virus vaccines administered after therapy may have reduced efficacy. Carboplatin may also potentiate live virus vaccine replication and increase adverse effects.
- Nephrotoxic agents (e.g., NSAIDs, Amphotericin B): Increased risk of cumulative nephrotoxicity.
- Vaccines (live): May adversely affect the safety and efficacy of vaccinations due to immunosuppression.
- Radiotherapy: Potential to act as a radiosensitizer for patients receiving concomitant radiotherapy.
