Meloxicam for Pigs: Uses, Dosing & 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 nonsteroidal anti-inflammatory drug (NSAID). Your vet may use it in pigs to help reduce pain, inflammation, and fever. It works by decreasing prostaglandin production, which is part of the body's inflammatory response.

In veterinary medicine, meloxicam is used across several species, including pigs. In the United States, however, meloxicam is not specifically labeled for pigs, so when your vet prescribes it for a pig, that is typically extra-label use. That matters because pigs are a food-animal species, and treatment decisions may need to include recordkeeping and withdrawal guidance.

Meloxicam comes in several formulations, including oral liquid and injectable products. The exact product, route, and schedule can change how the drug behaves in the body, so pig-specific instructions from your vet are important.

For pet pigs and miniature pigs, meloxicam is often one option within a broader pain-control plan. Depending on the situation, your vet may pair it with rest, hoof or joint care, wound management, or other pain medications rather than relying on one drug alone.

Your vet may use meloxicam in pigs for postoperative pain, lameness, soft tissue inflammation, arthritis-type discomfort, and fever or inflammatory illness when an NSAID is appropriate. Merck notes that meloxicam is used in pigs for fever, postoperative pain, and acute or chronic inflammatory conditions.

In miniature pet pigs, meloxicam may be considered when a pig is sore after a procedure, reluctant to rise, moving stiffly, or showing signs of ongoing inflammatory pain. It can also be part of supportive care while your vet works up the underlying cause of pain, because meloxicam treats symptoms but does not fix the reason they started.

Not every painful pig is a good candidate for meloxicam. Pigs that are dehydrated, have stomach or intestinal ulcer risk, kidney concerns, liver disease, or bleeding problems may need a different plan. Young piglets, pregnant animals, and pigs already taking other anti-inflammatory drugs also need extra caution.

Because pigs are food animals, your vet may also choose a different medication if residue concerns, slaughter timing, or herd-management realities make meloxicam a poor fit. That does not mean meloxicam is wrong. It means the best option depends on the pig, the diagnosis, and the practical goals of care.

Only your vet should determine the dose. Meloxicam dosing in pigs varies by formulation, route, age, health status, and treatment goal. Published veterinary references for miniature pigs list 0.1 to 0.2 mg/kg and some swine analgesia references use about 0.4 mg/kg by mouth every 24 hours. Those numbers are not interchangeable across products.

That range is exactly why home dosing is risky. A dog oral suspension, a compounded liquid, and an injectable product may all contain different concentrations. Even a small measuring error can lead to underdosing, poor pain control, or overdose.

Your vet may recommend meloxicam as a single dose, a short course over a few days, or part of a more structured pain plan. Longer use usually calls for more caution because NSAID risks can increase over time, especially if a pig stops eating or becomes dehydrated.

If your pig misses a dose, contact your vet for instructions rather than doubling the next one. If your pig is a food animal or could ever enter the food chain, ask your vet specifically about withdrawal guidance and treatment records before the first dose is given.

The most common meloxicam side effects are usually gastrointestinal. Watch for decreased appetite, vomiting, soft stool, diarrhea, teeth grinding, belly discomfort, or dark/tarry stool. In pigs, reduced appetite can be easy to miss at first, so subtle changes in feed interest matter.

More serious NSAID reactions can involve the stomach or intestines, kidneys, liver, or bleeding system. Call your vet promptly if your pig seems weak, becomes dehydrated, urinates less, develops yellowing of the skin, has blood in stool, or seems suddenly much more painful after starting the medication.

The risk of side effects goes up when meloxicam is given with the wrong dose, for too long, during dehydration, or alongside another NSAID or a steroid. Pigs that are already sick, stressed, or not eating normally may be more vulnerable.

See your vet immediately if your pig collapses, passes black stool, vomits blood, stops eating, or may have received too much meloxicam. NSAID toxicity can become serious quickly, and early treatment gives your pig the best chance of recovery.

Meloxicam should not be combined with another NSAID unless your vet has given a very specific plan. That includes drugs such as aspirin, flunixin, carprofen, firocoxib, or ibuprofen. Using two NSAIDs together can sharply increase the risk of stomach ulcers, bleeding, and kidney injury.

It also should not usually be given with corticosteroids such as prednisone or dexamethasone. This combination can raise the risk of gastrointestinal ulceration and other complications.

Extra caution is also needed with medications that can affect the kidneys, hydration status, or bleeding, including some antibiotics, diuretics, and anticoagulant-type drugs. If your pig is on any prescription medication, supplement, or compounded product, tell your vet before meloxicam is started.

If your pig is switching from one anti-inflammatory medication to another, ask your vet whether a washout period is needed. The safest timing depends on the drugs involved, the pig's health, and why treatment is changing.
