In Australia, meloxicam for dogs is a Schedule 4 Prescription Animal Remedy registered by the APVMA, and it cannot be bought over the counter — it comes from a vet, or on a vet's prescription. The standard dosing is 0.2 mg/kg on the first day, then 0.1 mg/kg once daily. What makes the Australian situation different from anywhere else is the sheer number of registered presentations: dog owners here can end up holding any one of several bottles or tablet packs, at three different concentrations, under at least four different brand names.
That variety is a real safety issue, not a shopping inconvenience, and it is the thing worth getting right before you read another word about side effects. The APVMA register carries a 0.5 mg/mL Metacam suspension for dogs and a separate 0.5 mg/mL Metacam suspension for cats, alongside the familiar 1.5 mg/mL dog bottle — three near-identical-looking products with two different strengths and two different target species. If you want the American picture for comparison, our guide to meloxicam for dogs covers the FDA label.
Every meloxicam product registered for Australian dogs
The APVMA's PubCRIS register is the public record of what is legally registered here. These are the meloxicam products currently registered for dogs, with their APVMA product codes and poison schedule:
| Product | APVMA code | Strength | Schedule |
|---|---|---|---|
| Metacam Anti-Inflammatory Oral Suspension for Dogs | 49655 | 1.5 mg/mL | S4 |
| Metacam 0.5 mg/mL Oral Suspension for Dogs | 60065 | 0.5 mg/mL | S4 |
| ilium Meloxicam Anti-Inflammatory Oral Suspension for Dogs | 60023 | 1.5 mg/mL | S4 |
| Vets' Own Meloxicam Dog Oral Suspension | 63653 | 1.5 mg/mL | S4 |
| Metacam Chewable Tablets for Dogs | 60535 / 60536 | 1 mg / 2.5 mg | S4 |
| Vets' Own Meloxicam Tablets | 92224 / 92225 | 1 mg / 2.5 mg | S4 |
| Metacam Anti-Inflammatory Injectable for Dogs and Cats | 55529 | 5 mg/mL | S4 |
| Metacam 0.5 mg/mL Oral Suspension for Cats | 61575 | 0.5 mg/mL | S4 |
Look at what that table does to the bottle-check problem. A 0.5 mg/mL bottle in an Australian household might be the dog suspension or the cat suspension. A 1.5 mg/mL bottle might be Metacam, ilium or Vets' Own. And measuring a dose worked out for 0.5 mg/mL out of a 1.5 mg/mL bottle delivers three times the meloxicam intended.
The habit that prevents all of it: before every dose from a new pack, read three things off the label — the strength in mg/mL, the species, and the brand — and check all three against the dispensing label your vet put on it. Bottle strengths do not transfer between brands, and neither do syringe graduations.
What S4 actually means for you and your vet
Schedule 4 in the Poisons Standard covers substances that should only be used or supplied by, or on the order of, people authorised under state or territory legislation to prescribe. For animal medicines this appears on the label as the signal words "Prescription Animal Remedy". Three things follow that are specific to Australia:
- Registration is federal; prescribing is state-based. The APVMA registers the product nationally, but the rules on how a vet writes, records and dispenses an S4 prescription sit in each state and territory's drugs and poisons legislation. Practical requirements can differ between, say, Victoria and New South Wales.
- A veterinarian–client–patient relationship is required. Your dog has to actually be under the care of the prescribing vet. That is why a genuine consultation, not a phone call about a dog the practice has never seen, precedes a first prescription.
- Repeats are not automatic. For a dog on long-term treatment, most practices will want a recheck before continuing to dispense — which is a clinical safeguard rather than a revenue exercise, given what this drug class does to kidneys and stomachs.
Australian meloxicam products are also subject to APVMA post-market oversight. Registered products can be and occasionally are recalled — another reason to buy through a veterinary channel that can contact you, rather than an unregulated overseas seller shipping unlabelled bottles.
What the drug does, and the numbers behind once-daily dosing
Meloxicam is an oxicam-class NSAID. It inhibits prostaglandin synthesis, preferentially blocking COX-2 — the enzyme driving inflammatory prostaglandins — over COX-1, which handles maintenance work like protecting the stomach lining and sustaining renal blood flow. Preferential is not exclusive, and that overlap is precisely why the gut and kidney warnings exist.
It is completely absorbed after oral dosing, is roughly 97% bound to plasma proteins, has a volume of distribution near 0.3 L/kg and an elimination half-life of about 24 hours — which is what makes it a once-a-day medication. Steady state is reached on the second day of treatment, so the drug is at full working concentration well before most owners can judge whether it is helping. Around three-quarters of a dose leaves via the faeces.
Clinically, a response is normally apparent within three to four days. Where treatment continues longer term, the dose is meant to be adjusted downward to the lowest effective individual dose once a response has been established, because musculo-skeletal pain fluctuates. A dog should not simply remain on the starting dose for years without review.
Dosing figures here are reproduced from registered product information for owner understanding only. They are not instructions — your veterinarian sets your dog's dose, and you should never adjust, skip, double or extend a prescription yourself.
Heat, dehydration and the Australian summer problem
This is not a marketing angle; it comes straight off the product information. Meloxicam should be avoided in any dehydrated, hypovolaemic or hypotensive animal, because of the potential risk of renal toxicity. NSAIDs reduce the prostaglandin signalling that maintains blood flow to the kidneys, and a dog that is already volume-depleted has lost its buffer.
In much of Australia that turns a general caution into a seasonal one. A dog on daily meloxicam through a 40-degree week, a long day at the beach, a bout of gastro, or an anaesthetic fast before a dental is in exactly the state the label warns about. Worth raising with your vet:
- Whether to skip a dose if your dog has been vomiting, has had diarrhoea, or has clearly not been drinking
- What to do about the dose around a surgical fast or a general anaesthetic
- Whether prolonged heat, hard exercise on hot days, or a long drive without water access changes anything for your dog specifically
- Whether your dog's kidney values warrant rechecking before summer rather than after
Do not make these calls unilaterally — stopping an NSAID abruptly has its own consequences for a painful dog. Ask, and get the answer recorded.
Contraindications, interactions and adverse effects
Dogs that should not receive it at all
Meloxicam is contraindicated in dogs with gastrointestinal disorders such as irritation or haemorrhage, impaired liver, cardiac or kidney function, and bleeding disorders, and in any dog hypersensitive to meloxicam or the formulation's excipients. It is not for very young puppies, and safety in pregnancy and lactation has not been established, so it should not be used in pregnant or lactating bitches.
Never with another anti-inflammatory
Meloxicam must not be given at the same time as other NSAIDs or corticosteroids — that combination sharply raises the risk of gastrointestinal ulceration and perforation. Other NSAIDs, diuretics, anticoagulants, aminoglycoside antibiotics and other highly protein-bound drugs may compete for plasma protein binding and produce toxic effects. Where a dog has been on an anti-inflammatory already, a treatment-free washout of at least 24 hours is required before meloxicam starts, and often longer depending on the previous drug's pharmacology. Your vet sets that interval; never bridge it with medication left over from a previous prescription or another pet.
If your dog needs more pain relief than meloxicam alone delivers, the answer is a drug from a different class — not a second anti-inflammatory.
Adverse effects: what to watch, and when it is urgent
| System | Reported effects | What you would see at home |
|---|---|---|
| Gastrointestinal | Appetite loss, vomiting, diarrhoea, blood in faeces, gastric and small intestinal ulceration | Refused meals; black, tarry or bloody stools; vomit like coffee grounds |
| Renal | Renal failure | Marked change in drinking or urination |
| Hepatic | Elevated liver enzymes | Yellowing of gums, skin or the whites of the eyes |
| General | Lethargy | Flat, withdrawn, not himself |
These reactions are classified as very rare — fewer than one animal in 10,000 treated. They typically appear within the first week of treatment and in most cases are transient, resolving once the drug is withdrawn, though in very rare cases they can be serious or fatal. That is the honest shape of the risk: uncommon, front-loaded, and worth watching closely rather than worrying about indefinitely.
If any of it appears, stop the medication and ring your vet the same day. Adverse experiences can be reported to the APVMA's Adverse Experience Reporting Program, usually via your veterinarian. For a suspected overdose — a dog that has got into the bottle — contact your vet or an after-hours emergency centre immediately.
A monitoring routine worth asking for
Because this is a drug many Australian dogs stay on for years, the monitoring conversation matters more than the dosing one:
- Before the first dose: ask for a baseline blood panel, so kidney values and liver enzymes have a genuine reference point to be compared against later.
- Through the first week: this is when adverse events typically show. Watch appetite, stool colour and water intake daily.
- At about two weeks: report honestly whether mobility has actually changed. If nothing has improved, that is a reason to review rather than persist.
- Long term: ask what recheck interval your vet wants, and whether the dose can be titrated down to the lowest effective amount now that a response is established.
- Before summer: raise the dehydration-and-kidneys question specifically.
What genuinely helps alongside the prescription
Nothing here replaces meloxicam, and nothing here should prompt you to change a prescription. But two levers sit outside the bottle.
Weight is the biggest one. A 2010 study in Veterinary Research Communications (PMID 20237844) put 14 obese client-owned dogs with osteoarthritis on a calorie-restricted diet for 16 weeks and recorded a significant decrease in lameness from about 6.1% body-weight loss onward. Six per cent is a realistic target for most households.
On supplements, the evidence is uneven, and the direction is worth stating. The largest analysis available is a 2022 systematic review and meta-analysis in the International Journal of Molecular Sciences (PMID 36142319), covering 72 trials across nine compound categories in canine and feline osteoarthritis.
| Ingredient class | What the 2022 meta-analysis concluded |
|---|---|
| Omega-3 (EPA/DHA) diets and supplements | Clear analgesic efficacy — the strongest signal in the review |
| Cannabidiol | Efficacy to a lesser degree |
| Collagen | Weak |
| Chondroitin–glucosamine | A "very marked non-effect"; the authors recommend these no longer be recommended for osteoarthritis pain |
That bottom row is inconvenient for most of the joint-supplement category, and we publish it because it explains our formulation logic. A two-ingredient glucosamine-and-chondroitin chew stakes its entire proposition on the one class this meta-analysis identifies as ineffective. Our Advanced Hip & Joint Chews carry 18 active ingredients across four functional layers, so the classes the evidence does favour — omega-3 fatty acids, green-lipped mussel and undenatured type-II collagen — are built in rather than tucked behind a glucosamine headline. For dogs who spit out chews, our liquid glucosamine for dogs pours over food, and the full dog joint and hip supplements range can be compared side by side. Every batch is made under GMP conditions with a certificate of analysis, and shipping is free worldwide.
Tell your vet what you are giving. Supplements belong in the clinical record beside the prescription — and if your dog is on an NSAID, that record is what protects him.
Meloxicam next to the other options
| Drug | Class | Mechanism | Notes |
|---|---|---|---|
| Meloxicam (Metacam, ilium, Vets' Own) | Oxicam NSAID | Preferential COX-2 inhibition | Once daily; widest range of registered presentations in Australia |
| Carprofen for dogs | NSAID | COX inhibition | Same class-wide gut and kidney cautions |
| Galliprant for dogs (grapiprant) | Piprant | Blocks the EP4 prostaglandin receptor | Not a COX inhibitor |
On meloxicam versus carprofen, the head-to-head evidence is thin. A 2003 study in Veterinary Record using force-plate gait analysis in 71 dogs (PMID 12665145) found both carprofen and meloxicam improved ground reaction forces while a nutraceutical did not. Which NSAID suits your dog is a matter of individual response and tolerance rather than ranking. Our overview of dog arthritis medicine covers the broader menu.
Frequently asked questions
Do I need a prescription for Metacam in Australia?
Yes. Meloxicam products for dogs are registered by the APVMA as Schedule 4 Prescription Animal Remedies, so they can only be supplied by or on the order of a veterinarian, and the label carries the signal words "Prescription Animal Remedy". The exact prescribing and dispensing rules sit in your state or territory's drugs and poisons legislation, so the paperwork can vary slightly depending on where you live.
Which meloxicam brands are registered for dogs in Australia?
The APVMA register lists several, including Metacam oral suspension for dogs at both 1.5 mg/mL and 0.5 mg/mL, Metacam chewable tablets at 1 mg and 2.5 mg, ilium Meloxicam oral suspension for dogs, Vets' Own meloxicam suspension and tablets, and an injectable form for dogs and cats. They share the same active substance, but strengths, syringes and dosing volumes differ between them — never carry a dose across from one brand to another.
My bottle says 0.5 mg/mL — is that the dog one or the cat one?
It could be either, which is exactly why the label must be read rather than assumed. Australia has both a 0.5 mg/mL Metacam oral suspension registered for dogs and a separate 0.5 mg/mL Metacam oral suspension registered for cats. Check the species printed on the pack and the dispensing label from your vet, and never give one animal's medicine to another.
Is meloxicam safe for my dog in hot weather?
The product information warns against using meloxicam in any dehydrated, hypovolaemic or hypotensive animal because of the risk of kidney toxicity, which makes heat, vomiting, diarrhoea and surgical fasting relevant considerations in an Australian summer. Ask your vet in advance what to do about dosing if your dog becomes dehydrated or is fasted for a procedure — do not stop or skip doses on your own.
Can meloxicam be given with cortisone or another anti-inflammatory?
No. Meloxicam must not be administered together with other NSAIDs or corticosteroids, because the combination substantially increases the risk of gastrointestinal ulceration and perforation. Moving between anti-inflammatories requires a washout period of at least 24 hours and frequently longer, determined by your veterinarian based on the previous medication.
How long can an Australian dog stay on meloxicam?
Many dogs take it long term under veterinary supervision, and there is no fixed cut-off. The registered product information directs that once a clinical response has been established, the dose be reduced to the lowest effective individual amount, and that treatment be reviewed rather than continued unchanged. Regular rechecks and blood monitoring become more important the longer treatment runs.
