Meloxicam (brand: Metacam) is a prescription anti‑inflammatory pain reliever for cats (an NSAID). It’s commonly used to reduce pain and inflammation after surgery; veterinarians may also use it for chronic joint pain (such as arthritis) in select cases under their direction. In the United States, meloxicam for cats is FDA‑approved only as a one‑time pre‑surgical injection; oral meloxicam products are not approved for cats. Your veterinarian can discuss why it was chosen for your cat and how it will be used safely.
What to watch for: vomiting, diarrhea, black/tarry stools, not eating, unusual sleepiness, or changes in drinking or urination—these can be signs of NSAID side effects on the stomach, liver, or kidneys. If you see these, call us the same day for guidance. Seek emergency care now for collapse, bloody vomiting/diarrhea, severe weakness, or if you suspect an overdose.
Front desk script: Meloxicam, brand name Metacam, is a prescription anti‑inflammatory pain reliever for cats. It’s often used for pain and inflammation after surgery; your veterinarian may also use it for arthritis pain in certain cats. In the U.S., it’s FDA‑approved for a single pre‑surgical injection in cats—your veterinarian will guide any use beyond that. If your cat vomits, has black stools, stops eating, or seems very tired, please call us the same day; for collapse or bloody vomiting/diarrhea, go to the nearest emergency vet.
Key points for cats: In the United States, meloxicam is only FDA‑approved for cats as a single injection around surgery. Repeated doses or using oral meloxicam in cats are not FDA‑approved and have been linked to acute kidney failure and death. Some veterinarians may still prescribe it off‑label in select cases; your veterinarian can explain why it was chosen for your cat and what monitoring is planned.
Common owner FAQs (short Q&A):
• “Is this safe for my cat?” — When used exactly as prescribed for your individual cat, it can help with pain. Cats are sensitive to this type of medication; never share doses, give extra doses, or use dog/human meloxicam in a cat. Your veterinarian can discuss benefits and risks based on your cat’s health.
• “What side effects should I watch for?” — Call the clinic if you see vomiting, diarrhea, poor appetite, unusual sleepiness, increased drinking/urination, or pale or yellow gums. Seek emergency care now for black, tarry stool, vomiting blood, facial swelling or hives, trouble breathing, or collapse.
• “Can it be given with other meds?” — Do not combine meloxicam with other pain relievers (like aspirin, ibuprofen, or other veterinary anti‑inflammatories) or with steroids (like prednisone) unless the veterinarian has directed it. Always tell us about all medications and supplements your cat takes.
• “What if I missed a dose or think I gave too much?” — Please call us for instructions before giving any more. If an overdose is possible or your cat has concerning signs, contact us or a 24/7 pet‑poison service right away.
• “How quickly will my cat feel better?” — Response time varies by cat and condition; your veterinarian can set expectations and follow‑up plans.
Front desk script: For cats, meloxicam is only FDA‑approved as a single injection around surgery; repeated or oral doses in cats have been linked to kidney failure. If you notice vomiting, diarrhea, not eating, black or bloody stool, vomiting blood, facial swelling, trouble breathing, or collapse, please go to the nearest emergency veterinarian now. If you missed a dose or think too much was given, please call us before giving any more so the veterinarian can guide you. Your veterinarian can also review which other meds are safe to use with meloxicam and what monitoring your cat may need.
What owners commonly report after meloxicam in cats: brief stomach upset (a single vomit, soft stool/diarrhea), reduced appetite, seeming tired/quiet, or mild soreness at the injection site within a day. These can occur with NSAIDs and should be noted for the medical team. Cats are more sensitive to NSAIDs than dogs, and in the U.S. meloxicam has a boxed warning for cats if more than the single approved injection is given.
Call the clinic the same day if there is more than one episode of vomiting in 24 hours, diarrhea that continues, not eating for a day, marked lethargy/hiding or behavior change, or clear changes in drinking or urination (much more or much less than usual). Yellowing of the gums/eyes, very pale gums, black/tarry stool or blood in stool/vomit, or a sudden collapse are emergency signs—direct the owner to the nearest emergency veterinary hospital now.
Special safety flags to escalate: the owner reports an extra dose, repeated doses after the single injection, or use with another pain/anti-inflammatory medicine (another NSAID or a steroid). These situations increase risk of kidney and gastrointestinal problems in cats and need veterinarian guidance right away. Your veterinarian can discuss risks, monitoring, and next steps with the owner.
Front desk script: Thanks for calling about your cat on meloxicam. Some cats can have mild stomach upset or seem a bit quiet; please tell me what you’re seeing so I can alert our veterinarian. If there’s repeated vomiting or diarrhea, not eating for a day, big changes in drinking or peeing, black or bloody stool, yellow or very pale gums, or your cat seems very weak, that needs urgent veterinary care—if severe, please head to the nearest ER now. Also let me know if any other pain meds were given or if an extra meloxicam dose was used, and our veterinarian will advise you on next steps.
Forms you may see: meloxicam for cats is usually given as a one‑time injection at the clinic; if a liquid is sent home, that use in cats isn’t FDA‑approved but may be prescribed by the veterinarian. For oral liquid, use the dosing syringe, shake if the label says “suspension,” and give with a small meal or a hand‑fed spoonful of wet food to help prevent stomach upset and be sure the full dose is eaten. If giving directly, place the syringe in the cheek pouch (side of the mouth) and slowly give small amounts so the cat can swallow; mild drooling/foaming from the taste can be normal. Do not hide the dose in a large bowl of food that the cat may not finish. Your veterinarian can show the technique in person if needed. [FDA warns that repeated meloxicam exposure in cats carries kidney risk—follow the veterinarian’s exact directions and call with concerns.]
Troubleshooting: If the cat resists the flavor, ask the veterinarian about compounding (e.g., chicken/tuna‑flavored liquid or tiny capsules) or other clinic‑approved alternatives. For tablets/capsules, you can use a small treat “meatball,” a pill pocket, or place the pill quickly at the back of the tongue and offer a sip of water after to help it go down. If any medication is spit out or the cat vomits, contact the veterinarian for instructions before giving more—don’t re‑dose on your own.
When to escalate: Call the clinic the same day for vomiting, diarrhea, poor appetite, or increased drinking/urination. This is urgent immediately if there is repeated vomiting, black/tarry stool or blood in vomit, marked lethargy, collapse, or not producing urine; advise prompt veterinary care or emergency evaluation. Your veterinarian can discuss food timing, flavor options, and what to do if doses are missed or vomited.
Front desk script: Most cats go home with a liquid; use the oral syringe, shake if it’s a suspension, and give it with a small bite of wet food or slowly into the cheek pouch so it’s swallowed. Please don’t hide it in a full food bowl because we can’t tell if the whole dose was eaten. If your cat spits it out or vomits, please call us before giving any more so the doctor can advise. If you see black or bloody stool, repeated vomiting, extreme tiredness, or your cat isn’t urinating, that’s urgent—head to our clinic now or the nearest ER.
Refills for meloxicam in cats must be reviewed by a veterinarian each time. In the United States, repeated meloxicam use in cats carries an FDA boxed warning because repeated doses have been associated with acute kidney failure and death; oral meloxicam products are not approved for cats in the U.S. Any ongoing use is extra‑label and requires veterinarian authorization. Do not promise or authorize refills without clinician approval. The veterinarian may require a recent exam and lab monitoring (blood and/or urine) before approving a refill and will determine if continued use is appropriate.
When taking a refill request, collect: pet name and DOB, client name/contacts, exact medication name and form, how much is left, how the cat is doing on the medication, any side effects, any other meds/supplements, preferred pharmacy (clinic or online), and pickup/shipping preference. Ask specifically about red‑flag signs while on an NSAID: vomiting, diarrhea, black/tarry stool, not eating, marked lethargy, changes in drinking or urination, or yellow gums/skin. If any are present, escalate to the medical team immediately and do not assure a refill. For online pharmacy requests, route to the veterinarian for written approval; quantity may be limited and monitoring may be required.
Turnaround: advise that a veterinarian review is required; staff should set expectations for a response after the doctor reviews the record. Reexamination and monitoring schedules vary by patient; your veterinarian can discuss the timing and safety plan with the client.
Front desk script: Thanks for calling about a meloxicam refill for your cat. Because meloxicam use in cats requires veterinarian review due to FDA safety warnings, I’ll send this to the doctor now. Before I do, has your cat had any vomiting, diarrhea, black stools, not eating, big changes in drinking or urination, or yellow gums/skin? If any of those are happening, I’ll connect you with our medical team right away. Once the doctor reviews the record—and lets us know if any recheck or lab work is needed—we’ll update you on the refill. If you prefer an online pharmacy, we’ll submit the request for doctor approval and let you know about any limits.
This medication carries a boxed warning for cats: repeated meloxicam doses (including additional injections or any oral meloxicam products) have been associated with acute kidney failure and death. If a cat received more than prescribed, was given a dog‑only/oral meloxicam product, or meloxicam was given together with another NSAID or a steroid, treat this as an emergency and get a veterinarian/technician immediately. Red‑flag toxicity signs include vomiting or diarrhea (with or without blood), black/tarry stool, vomiting blood, not eating, marked lethargy, belly pain, seizures, or changes in thirst or urination—these can signal gastrointestinal bleeding or kidney injury and require urgent escalation. ([fda.gov](https://www.fda.gov/animal-veterinary/product-safety-information/information-about-boxed-warning-meloxicam-labels-regarding-safety-risks-cats))
Also escalate immediately for possible severe allergic reaction after a dose: swelling of the face or muzzle, hives, trouble breathing, collapse, or sudden severe vomiting/diarrhea. Cats with underlying kidney or liver disease are higher risk; if they show decreased appetite, vomiting, or behavior changes while on meloxicam, get a vet/tech right away. Your veterinarian can discuss risks, drug interactions, and what monitoring is appropriate for this pet.

Front desk script: Because this involves meloxicam in a cat and the signs you’re describing could be serious, I’m getting a veterinarian or technician on the line right now. If we can’t connect in under a minute, please come to our hospital or the nearest emergency clinic immediately and bring the medication packaging. If any facial swelling, trouble breathing, black/tarry stool, or an extra dose or other pain medicine was given with meloxicam, this is an emergency. Our veterinarian can explain the risks and what monitoring is needed for your cat.
Meloxicam (Metacam) is a veterinary NSAID. In cats, the FDA allows only a single pre‑surgical injection; repeated doses or giving oral meloxicam to cats has been linked to acute kidney failure and death. Always flag when owners mention other meds, because certain combinations raise GI bleeding and kidney risks. Your veterinarian can discuss safe combinations and timing for that individual cat.
Common interaction flags and frequently mentioned meds: do not combine meloxicam with other anti‑inflammatories (e.g., robenacoxib/Onsior, aspirin, other NSAIDs) or with steroids (e.g., prednisone/prednisolone)—these require immediate veterinarian review. Use caution/flag if the cat is also on diuretics (e.g., furosemide), nephrotoxic antibiotics (e.g., gentamicin/amikacin), antifungals (e.g., fluconazole), or immunosuppressants (e.g., cyclosporine/methotrexate); anesthetic drugs around surgery also warrant vet oversight.
OTC human pain meds to specifically screen for: acetaminophen (Tylenol), ibuprofen (Advil/Motrin), naproxen (Aleve), and aspirin. Cats should never receive acetaminophen, and human NSAIDs are unsafe—if an owner has given any of these, escalate immediately. Urgent side effects to flag for same‑day/ER handoff include vomiting, diarrhea, black/tarry stool, not eating, marked lethargy, or increased thirst/urination; the veterinarian will advise next steps.
Front desk script: Thanks for telling me about the other medication. Because meloxicam is an anti‑inflammatory, we avoid mixing it with other anti‑inflammatories (like Onsior/robenacoxib or aspirin) or with steroids such as prednisolone—I’m going to flag this and check with the veterinarian right away. If any human pain reliever was given (Tylenol/acetaminophen, Advil/ibuprofen, Aleve/naproxen, or aspirin), that can be dangerous for cats—please head to the nearest emergency clinic now and I’ll alert our doctor. If your cat is showing vomiting, black stool, not eating, or unusual thirst/urination, please let me know immediately so I can transfer you for urgent veterinary guidance.
Storage: Keep Metacam (meloxicam) oral suspension at controlled room temperature (68–77°F/20–25°C). Short excursions between 59–86°F are permitted, but avoid heat (e.g., a hot car) and do not freeze. Keep the cap tight, store in the original child‑resistant bottle, and shake before each use. Always keep out of sight and reach of children and pets; in case of accidental human ingestion, seek medical advice immediately. Your veterinarian can discuss any clinic‑specific handling instructions.
Shelf life after opening: Cat‑labeled Metacam 0.5 mg/mL has a defined in‑use shelf life based on bottle size: 3 mL bottles must be used within 14 days of opening; 10 mL, 15 mL, and 30 mL bottles within 6 months of opening. If your clinic dispenses a different product (e.g., the U.S. dog‑labeled oral suspension or a compounded product), follow the pharmacy label/beyond‑use date or the printed package expiry as directed; when in doubt, your veterinarian can confirm how long your client’s bottle is good after opening.
Disposal and safety: Do not flush unless the label specifically instructs. Prefer a medicine take‑back program or mail‑back. If no take‑back is available, place unused liquid in a sealed container mixed with something unpalatable (e.g., used coffee grounds or cat litter) before discarding in household trash; remove or obscure personal information on labels. If a child or any pet chews the bottle or drinks extra medication, or if the cat shows vomiting, diarrhea, black/tarry stools, marked lethargy, or collapse, this is urgent—call the clinic or the nearest emergency hospital immediately. Your veterinarian can advise on safe storage and what to watch for.
In the United States, meloxicam for cats is FDA‑approved only as a single injection given around surgery. Repeated doses or oral use in cats are extra‑label and carry an FDA boxed warning because repeated use has been associated with acute kidney failure and death. Your veterinarian will determine if meloxicam is appropriate and what follow‑up is needed for that individual cat.
If a cat received the single peri‑operative injection, schedule the surgeon’s routine post‑op recheck as directed; no medication‑specific lab visit is usually needed unless the veterinarian requests one. Advise owners to watch closely during the first few days for decreased appetite, vomiting/diarrhea, or unusual lethargy, and to contact the clinic immediately if seen.
If a veterinarian prescribes ongoing/extra‑label meloxicam, plan for: baseline evaluation with blood and urine tests (kidney and liver) and, when possible, blood pressure before starting; an early recheck at about 5–7 days; another recheck at 2–4 weeks; then periodic rechecks set by the veterinarian (often at least every 6 months in lower‑risk cats, and every 2–6 months in higher‑risk cats). At each visit the team reviews appetite, stools, drinking/urination, and overall comfort. Any changes to medication or monitoring schedule are made by the veterinarian.
Front desk script: For cats, meloxicam is usually a one‑time injection around surgery. If that’s the case, we’ll get you scheduled for the routine post‑op recheck your surgeon recommends. If the doctor has prescribed meloxicam for ongoing use, we’ll book baseline blood/urine tests first, a quick recheck in about a week, then another at 2–4 weeks; your veterinarian will set the long‑term checkup schedule. If you notice vomiting, black or bloody stool, your cat not eating, marked lethargy, big changes in thirst or urination, or your cat seems very unwell, please go to the nearest emergency clinic now or call us immediately. If you have any dosing or stop/start questions, the veterinarian can advise you.
Meloxicam (Metacam) is a prescription anti‑inflammatory pain reliever. In the United States, it is FDA‑approved for cats only as a single injection around surgery; oral meloxicam products are not approved for cats. Because safety depends on the cat’s specific plan, all questions about how or when to give it, missed or extra doses, or combining with any other medications must be answered by the veterinarian.
Screen for red flags and escalate: vomiting or diarrhea, very dark/black stools, not eating, marked lethargy, sudden changes in drinking or urination, yellow gums/eyes, or if any dog product or extra doses were given. If any are present, keep the caller on the line, alert a medical team member immediately, and, if a doctor isn’t available at once, direct the client to the nearest emergency veterinary hospital.
Use: “I’ll relay your question to the veterinarian,” “Let me place you on a brief hold while I check with the medical team,” and “I can arrange a same‑day call or visit.” Avoid: saying “It’s safe to keep giving it,” offering any dosing numbers, comparing it to human pain relievers (e.g., ibuprofen/aspirin), or telling a client to start or stop the medication—those decisions are for the veterinarian.
Front desk script: Thank you for calling [Clinic Name], this is [Your Name]. Meloxicam (Metacam) is a prescription anti‑inflammatory pain reliever; for cats here in the U.S. it must be used only as directed by our veterinarian, so I’ll confirm your question with the doctor. May I place you on a brief hold or schedule a same‑day callback so the medical team can advise next steps? If your cat has vomiting, very dark stools, won’t eat, seems very lethargic, or may have received an extra dose or a dog product, please tell me now so we can connect you with urgent care.
