Meloxicam (Metacam) for Rabbits: Dosage, Uses & Side Effects

This information is for educational purposes only. Never give your pet any medication without your veterinarian's guidance. Dosing, frequency, and safety depend on your pet's specific health profile.

Meloxicam is a prescription nonsteroidal anti-inflammatory drug, or NSAID. Your vet may use it in rabbits to help reduce pain and inflammation. It is commonly dispensed as an oral liquid, though injectable forms also exist.

In rabbits, meloxicam is usually an extra-label medication. That means it is prescribed by your vet based on rabbit-specific experience and published veterinary references rather than a rabbit label claim. This is common in exotic animal medicine and does not mean the drug is inappropriate.

Meloxicam works by reducing prostaglandin production, which helps decrease inflammation and discomfort. Compared with some older NSAIDs, it is considered relatively COX-2 selective, which may improve gastrointestinal safety, but it still carries real risks and should only be used under veterinary supervision.

For many rabbits, pain control is not optional supportive care. Pain can reduce appetite, slow gut movement, and worsen recovery after surgery or illness. That is why your vet may include meloxicam as one part of a broader treatment plan rather than as a stand-alone fix.

Your vet may prescribe meloxicam for short-term pain after procedures such as spay, neuter, dental work, mass removal, or other surgery. Merck Veterinary Manual specifically lists meloxicam among NSAID options used for rabbit analgesia, including postoperative care.

It may also be used when inflammation is part of the problem. Examples can include dental disease, soft tissue injury, sore hocks, arthritis-like mobility pain, urinary discomfort, or other painful conditions where an anti-inflammatory may help. In rabbits with GI stasis, pain relief can be especially important because painful rabbits often stop eating.

Meloxicam is not an antibiotic, sedative, or cure for the underlying disease. It helps manage discomfort while your vet addresses the cause. Some rabbits need only a brief course, while others with chronic pain may need a longer-term plan with monitoring and dose adjustments.

Because rabbits hide illness well, a rabbit that seems quiet, hunched, tooth-grinding, or less interested in food may be painful. Those signs should prompt a call to your vet rather than starting leftover medication at home.

Rabbit meloxicam dosing varies by the reason for treatment, the formulation used, your rabbit's weight, hydration status, kidney and liver health, and whether other pain medications are being used. Published rabbit references commonly cite around 1 mg/kg by mouth or injection every 24 hours for analgesia, but actual prescribed doses can vary. Your vet may choose a different plan based on the clinical situation.

Accuracy matters. Meloxicam oral liquids come in different concentrations, and small measuring errors can cause underdosing or overdose. Use only the syringe or measuring device your vet provides, and confirm the concentration on the bottle every time you refill it. Do not substitute a dog, cat, or human product without your vet's approval.

Many vets recommend giving meloxicam with food when possible, and rabbits on longer courses may need rechecks or lab work. If your rabbit misses a dose, contact your vet for guidance. Do not double the next dose unless your vet specifically tells you to.

Never guess a rabbit dose from internet charts, social media posts, or another species' label. Rabbits have unique pain-management needs, and the safest dose is the one your vet calculates for your individual pet.

Many rabbits tolerate meloxicam well when it is prescribed thoughtfully, but side effects are still possible. The biggest concerns with NSAIDs are stomach or intestinal irritation, reduced appetite, kidney stress, liver irritation, and problems that become more likely with dehydration, overdose, or use alongside other risky medications.

Call your vet promptly if your rabbit eats less, seems more lethargic, has diarrhea, produces very small fecal output, seems painful despite treatment, or shows any change in drinking or urination. In rabbits, even subtle appetite changes matter because reduced food intake can quickly contribute to GI slowdown.

See your vet immediately if your rabbit stops eating, becomes weak, collapses, has black or bloody stool, develops severe diarrhea, or you suspect an overdose. Those signs can point to a serious adverse reaction or to the underlying illness getting worse.

If your rabbit is older, dehydrated, has kidney disease, liver disease, stomach ulcer risk, or is already medically fragile, your vet may recommend closer monitoring or a different pain-control plan. Conservative care can still be appropriate, but it needs to be individualized.

Meloxicam should not be combined with another NSAID unless your vet gives a specific transition plan. It also should not be mixed with corticosteroids such as prednisone or prednisolone because that combination can sharply increase the risk of gastrointestinal ulceration and other complications.

Your vet should also know about any diuretics, anticoagulants, certain antibiotics such as gentamicin or amikacin, some anesthetic drugs, methotrexate, cyclosporine, fluconazole, supplements, and any compounded medications your rabbit receives. These combinations may increase kidney risk, bleeding risk, or drug exposure.

This matters even more in rabbits that are not eating well or are dehydrated. A medication combination that might be tolerated in a stable patient can become much riskier when circulation to the kidneys is reduced.

Before every refill, tell your vet about all medications and supplements your rabbit is taking, including anything borrowed from another pet. Human meloxicam, ibuprofen, naproxen, aspirin, and similar products should never be started at home unless your vet specifically instructs you to use them.
