Palladia (generic name: toceranib) is a prescription-only targeted cancer medicine for dogs. It’s a type of chemotherapy called a tyrosine kinase inhibitor that blocks signals tumors use to grow and make a blood supply.
Most commonly, veterinarians prescribe Palladia for mast cell skin tumors in dogs, especially when tumors have come back or can’t be fully removed. It may also be used, at your veterinarian’s discretion, for select other cancers in dogs. Dogs only; not for people or other species.
Your veterinarian can discuss why it was chosen for this pet and what to expect during treatment. For any questions about how to give it, monitoring, or side effects, please refer the owner to the veterinarian or oncology team.
Front desk script: Palladia—also called toceranib—is a targeted chemotherapy tablet for dogs. It’s most often used for mast cell skin tumors and is prescription-only.

Top owner FAQs about Palladia (toceranib) for dogs:
- What is it and why is my dog on it? Palladia is a targeted chemotherapy pill for dogs, FDA‑approved to treat certain skin mast cell tumors. Some veterinarians also use it for other cancers; your veterinarian can explain your dog’s specific treatment goal. [Deferral]
- How do we handle the tablets safely at home? Do not split or crush the tablets. Keep them away from children. Wear disposable gloves to give the pill and when cleaning urine, feces, or vomit for a few days after a dose; seal waste in a plastic bag and wash hands well after. People who are pregnant or nursing should avoid handling the medication and pet waste. [Safety boundary]
- What side effects should we watch for? Common effects include decreased appetite, vomiting, diarrhea, low energy, weight loss, and lameness. Call us the same day if there is repeated vomiting or diarrhea, your dog won’t eat, seems very weak, or you see black/tarry stools or blood in vomit or stool. If your dog collapses or has trouble breathing, seek emergency care immediately. [Escalation]
- Can it be given with other meds or supplements? Some medicines can interact with Palladia and pain relievers may raise the risk of stomach ulcers. Check with our veterinarian before giving any new prescription, over‑the‑counter, or supplement. [Deferral]
- What if we miss a dose? Do not give extra or double up. Call us for instructions so the veterinarian can advise the next steps. [Deferral]
- Do we need check‑ins? Yes. Dogs on Palladia need regular exams and lab monitoring; your veterinarian will set the schedule and discuss any changes needed. [Deferral]
Front desk script: Palladia is a targeted chemotherapy pill for dogs. Please give it exactly as directed, don’t split or crush tablets, and use gloves when handling the pill or cleaning your dog’s urine, stool, or vomit; wash hands after. If you see repeated vomiting or diarrhea, your dog won’t eat, seems very weak, or you notice black or bloody stool or vomit, this is urgent—call us right away; if we’re closed, go to the nearest emergency clinic. Don’t add or double doses or start any new meds without checking with our veterinarian—they can review the plan and monitoring at your visit.
What owners commonly report with Palladia: loose or watery stools/diarrhea, vomiting, decreased appetite, low energy/tiredness, gradual weight loss, occasional limping, and sometimes skin or nose color changes. These effects are usually gastrointestinal and may show up early in treatment. Your veterinarian monitors for less visible issues (like low white blood cell counts or protein changes) with planned lab work.
What’s often okay to monitor short-term: a single soft stool, one episode of vomiting, or mild tiredness that resolves within a day. Call the clinic the same day if any of the following occur: watery diarrhea 3 or more times in 24 hours or diarrhea lasting over 48 hours; vomiting more than twice in 24 hours; refusal to eat for about a day; black, tarry stool or bright red blood in stool or vomit; new bruising or bleeding; nosebleeds; new leg swelling or trouble breathing. These can be serious and may need prompt evaluation—if the clinic is closed, use an emergency hospital. Your veterinarian can discuss what to do about upcoming doses and whether any testing is needed.
Front desk script: Thanks for calling about your dog on Palladia. The most common reactions owners report are loose stool, vomiting, a lower appetite, and tiredness. Because you’re seeing this, I’m going to flag it for our veterinarian today—if you notice black/tarry stool, red blood in stool or vomit, vomiting more than twice in 24 hours, watery diarrhea three or more times in a day, not eating for a day, new bruising/bleeding, or breathing trouble or leg swelling, please treat that as urgent and use the nearest emergency clinic if we’re closed. Our veterinarian can advise on next steps and monitoring.
Form: Palladia is only available as film‑coated oral tablets for dogs. Tablets must be given whole—do not split, crush, or open. Handle with care: wear disposable gloves, wash hands after, keep away from children, and people who are pregnant or breastfeeding should avoid handling. You may give it with or without food; if a dog seems nauseous on an empty stomach, offering the dose in a small bite of food is acceptable. Make sure the entire bite is eaten.
Troubleshooting giving: Use a pill pocket or a tiny “meatball” of canned food, followed by a treat to encourage swallowing. Offer a small test treat first, then the medicated bite, then another treat. If the pet refuses tablets or can’t take them whole, do not alter the tablet—your veterinarian can discuss alternate tablet strength combinations or, when medically appropriate, referral to a USP‑compliant compounding pharmacy; this must be arranged by the prescriber due to safety and regulatory requirements for hazardous chemotherapy drugs.
Vomiting/food interactions: If the dog vomits after a dose, do not give an extra dose unless the veterinarian specifically instructs it. Call the clinic for guidance, especially if vomiting or diarrhea persists, the dog won’t eat, seems very lethargic, or you see fresh blood or black/tarry stools—these need prompt veterinary evaluation. After hours, seek emergency care for these signs.
Front desk script: These are film‑coated tablets that need to be given whole. You can hide a tablet in a small treat or pill pocket—just be sure your dog eats the entire bite, and please handle the tablets with gloves. If your dog vomits after the dose, don’t repeat it; give us a call so the doctor can advise next steps. If you see blood in vomit or stool, black stools, repeated vomiting/diarrhea, or your dog won’t eat, please contact us right away or go to the nearest emergency hospital after hours. If tablets are too hard to give, our veterinarian can discuss other strength combinations or a specialty compounding option.
Palladia is a prescription-only chemotherapy for dogs. Refills must be reviewed and authorized by a veterinarian because the label requires ongoing veterinary oversight and that a Client Information Sheet be provided with each prescription. Advise callers that refills may be held if a recheck exam or recent lab work is due; the veterinarian will determine the monitoring schedule. ([vetlabel.com](https://vetlabel.com/lib/vet/meds/palladia/))
Standard refill workflow: collect the pet’s name and DOB, owner’s name, medication and strength, quantity remaining, any side effects since the last fill, preferred pharmacy, and a call-back number. Typical turnaround is 1–2 business days for the doctor to review the record; set expectations that oncology refills can require more time if labs or re-exam are needed. Do not promise a refill if monitoring is overdue—route to the veterinarian to advise on next steps. If the caller reports red-flag signs (e.g., vomiting or diarrhea, black/tarry stools or blood in stool/vomit, unusual bruising/bleeding, refusal to eat, marked lethargy/collapse), escalate to a veterinarian immediately; this may warrant same-day evaluation. ([vetlabel.com](https://vetlabel.com/lib/vet/meds/palladia/))
Online pharmacy process: we can send approved refills to a licensed U.S. pharmacy that requires a veterinarian’s prescription. Verify the pharmacy request includes licensing details and a U.S. address; avoid sites that don’t require an Rx or hide contact info. Once approved, transmit the Rx and ensure the Client Information Sheet accompanies the order. Remind owners that Palladia has human safety precautions (keep away from children; special care for pregnant or breastfeeding people); any handling questions should be discussed with the veterinarian. ([fda.gov](https://www.fda.gov/animal-veterinary/animal-health-literacy/need-pet-meds-protect-yourself-and-your-pet-be-website-aware?utm_source=openai))
Front desk script: Thanks for calling about a Palladia refill. Because this is a chemotherapy medication, our doctor needs to review your pet’s chart and recent labs before we can approve it. May I confirm your pet’s name and DOB, the Palladia strength, how many tablets you have left, your preferred pharmacy, and whether you’ve noticed any side effects? Our typical turnaround is 1–2 business days; if you’re seeing vomiting, diarrhea, black or tarry stools, bleeding, refusal to eat, or your dog is very lethargic, I’ll alert a veterinarian right now and we may direct you to same-day care.
Escalate to a veterinarian immediately for any signs of internal bleeding or a gastrointestinal emergency while on Palladia: black or tarry stools, visible blood in vomit or stool, repeated or worsening vomiting or diarrhea, sudden severe belly pain, collapse, or marked dehydration. These can signal serious complications, including GI ulceration or, rarely, life‑threatening perforation reported with Palladia. This is an emergency. ([vetlabel.com](https://vetlabel.com/lib/vet/meds/palladia/page/2/))
Also escalate now for sudden trouble breathing, new limb swelling, or weakness/collapse (possible blood clot/vascular event); unusual bruising, nosebleeds, pale gums, or widespread bleeding; fever with extreme lethargy; or a prolonged lack of appetite. Palladia can affect blood vessels and bone marrow (low white cells/platelets), so these signs need same‑day veterinary assessment. Your veterinarian can discuss what is expected versus abnormal for this patient. ([vetlabel.com](https://vetlabel.com/lib/vet/meds/palladia/page/2/))
If an overdose is suspected—or if you see loss of appetite, vomiting, diarrhea, low energy, bleeding/bruising, new limping, or muscle cramps—treat this as urgent and connect with a veterinarian or emergency hospital right away. Any severe allergic reaction signs (sudden facial/muzzle swelling, hives, or trouble breathing) are emergencies. ([petmd.com](https://www.petmd.com/pet-medication/toceranib-palladia-dogs))
Front desk script: Thanks for calling—based on what you’re seeing while your dog is on Palladia, this needs urgent medical attention. I’m getting a veterinarian or technician on the line now. If your dog is having trouble breathing, has black or bloody stool/vomit, collapses, or you think there was an overdose, please head to the nearest emergency hospital immediately. Your veterinarian will advise next steps once I connect you.
Key interactions to flag with Palladia (toceranib) in dogs: nonsteroidal anti-inflammatory drugs (NSAIDs) because together they raise the risk of stomach/intestinal ulcers and even perforation; strong CYP3A4 inhibitors (especially azole antifungals like ketoconazole/itraconazole and some macrolide antibiotics) because they can raise Palladia levels; other cytotoxic anticancer drugs; calcitriol; and live or modified‑live vaccines (avoid while on therapy—veterinarian to advise timing). If an owner reports black tarry stools, vomiting blood, severe belly pain, sudden collapse, or trouble breathing, treat this as an emergency and direct them to the nearest ER immediately; then notify the veterinarian. Your veterinarian can discuss any medication changes and the safest plan for that specific patient.
Commonly co‑prescribed meds you may hear about with Palladia (under oncology direction): prednisone/prednisolone; diphenhydramine; famotidine; omeprazole; and maropitant (Cerenia) for nausea. These are often used to manage mast cell tumor effects and GI upset during therapy; still, always document and hand off to the veterinarian before starting, stopping, or combining anything new.
OTC items owners commonly give that require a flag: human pain relievers such as ibuprofen or naproxen (do not use—toxic to dogs and can worsen GI bleeding risk); antacids/acid reducers (famotidine, omeprazole) and antihistamines (diphenhydramine)—generally used under vet guidance but still worth confirming; vitamins/herbals/supplements (including "natural" products) should also be cleared by the veterinarian. If the owner asks about vaccines while on Palladia, defer to the veterinarian as live or modified‑live vaccines should not be given during treatment.
Front desk script: Thanks for letting me know about the other medication. Palladia can interact with some drugs, so I’m going to note this and have our veterinarian review it today before you start or stop anything. If you notice black stools, vomiting blood, severe belly pain, collapse, or trouble breathing, please go to the nearest emergency hospital now and call us on the way. Also, please avoid giving human pain meds like ibuprofen or naproxen—those are not safe for dogs.
Storage: Keep Palladia (toceranib) tablets in their original, child‑resistant container at room temperature 68–77°F (20–25°C). There is no special shorter “after opening” shelf life listed for these tablets—use until the bottle’s expiration date. Keep the container closed and stored securely away from children and other pets.
Handling: Do not split, crush, or handle broken or moistened tablets. After giving a dose, wash hands with soap and water. Anyone handling pet waste for a few days after dosing should wear disposable gloves and avoid bare‑skin contact with urine, feces, or vomit. Place waste materials (including any broken/moistened tablets) in a plastic bag, seal it, and discard in household trash. Pregnant or nursing individuals, or those who may become pregnant, should avoid handling tablets and pet waste. If owners have questions about safe handling at home, the veterinarian can discuss specific precautions for their household.
Disposal: For unused or expired tablets, ask the clinic or a pharmacy about a medication take‑back option; do not flush or pour into wastewater. If accidental human exposure occurs: rinse eyes immediately if exposed; if a person swallows a tablet, seek medical advice right away and bring the package insert—this is urgent.
Typical follow-up for dogs on Palladia includes frequent early check-ins, then spacing out once stable. Per the manufacturer label, the veterinary team assesses patients about weekly during the first 6 weeks, then about every 6 weeks thereafter; many oncology services schedule rechecks at 2, 4, 8, and 12 weeks after starting, then every 2–3 months as directed by the veterinarian. The exact timetable is set by the doctor based on the pet’s condition and lab results.([vetlabel.com](https://vetlabel.com/lib/vet/meds/palladia/))
At these visits, expect a physical exam and weight, plus lab monitoring to watch for common issues with tyrosine kinase inhibitors: a complete blood count, a serum chemistry panel, a urinalysis (and urine protein:creatinine ratio if indicated), and a blood pressure check. This helps catch GI side effects, low white cell counts, liver or kidney changes, high blood pressure, and protein loss in urine early. Your veterinarian can discuss if tumor measurements or imaging are needed at specific rechecks.([aaha.org](https://www.aaha.org/resources/2026-aaha-oncology-guidelines-for-dogs-and-cats/section-5-therapeutic-interventions/therapeutic-modalities-chemotherapy/))
Escalate scheduling if owners report red flags: black/tarry stool or visible blood in stool/vomit, repeated vomiting or diarrhea (e.g., more than a day), refusal to eat, marked lethargy/weakness, or pale gums. Book a same‑day urgent appointment when possible and alert the veterinarian immediately; if after hours, direct the caller to emergency care. Do not advise starting, stopping, or changing medication—defer to the veterinarian for instructions.([vetlabel.com](https://vetlabel.com/lib/vet/meds/palladia/page/2/))
Front desk script: Our doctors like to see dogs on Palladia more often at the beginning—typically several visits in the first 6 weeks—then we space rechecks out as your veterinarian directs. At each visit, we’ll check weight, examine your dog, and run blood and urine tests, and a blood pressure reading to make sure the medication is being tolerated. These check‑ins help us catch side effects early and keep treatment as safe as possible. If you ever see black or bloody stool, vomiting or diarrhea that lasts, refusal to eat, or your dog seems very weak, please call us right away or go to the ER after hours; the veterinarian will guide next steps.
Palladia (toceranib) is a prescription anti-cancer medication for dogs. Front-desk role: confirm the pet, medication, and prescribing doctor; document the caller’s concern; and route to the medical team. Common side effects owners may report include vomiting, diarrhea, not wanting to eat, lethargy, lameness, weight loss, and blood or black/tarry stools. Handling safety for households: keep tablets away from children; do not crush or split; wash hands after giving; wear gloves to clean urine, feces, or vomit; and people who are pregnant or nursing should avoid handling. Your veterinarian can discuss if labs, dose changes, or a visit are needed based on the pet’s signs.
Escalation guidance for calls: if there is blood in vomit/stool, black/tarry stool, repeated vomiting/diarrhea, refusal to eat for 24 hours, unusual bruising/bleeding, severe weakness, or fever, mark as urgent for same-day clinician callback. If the pet collapses, has trouble breathing, or has very pale gums, direct the caller to proceed to the nearest emergency hospital now. Do not advise giving, skipping, repeating, or stopping doses—defer to the veterinarian.
Phrases to avoid: “It’s safe to give/skip another dose,” “Keep giving it until it’s gone,” “This is just like a regular med,” or any dosing or treatment instructions. Preferred phrasing: “I can’t advise dosing or whether to hold a dose; our veterinarian will guide you.”
