Metacam for Dogs: Side Effects, Dosage & Alternatives
Your vet has prescribed Metacam. Your dog is moving around better again and is taking the liquid without any problems – but the question remains in the back of your mind: how long can I keep giving it to him? And what effect does it have on his organs?
You’re not alone in this. Metacam is the most commonly prescribed painkiller for dogs in Germany. Every month, thousands of dog owners search online for information on side effects, dosage and alternatives. And rightly so.
TL;DR
- Metacam (meloxicam) is an anti-inflammatory painkiller (NSAID) – it works quickly, but isn’t without risk
- Common side effects affect the stomach, liver and kidneys – particularly with long-term use
- Metacam treats the symptoms, not the cause of joint problems
- Natural dietary supplements such as green-lipped mussel, glucosamine and MSM can provide long-term support – either as a supplement or after stopping treatment
What exactly is Metacam?
Metacam is the trade name for the active ingredient meloxicam. It belongs to the group of non-steroidal anti-inflammatory drugs (NSAIDs) – the same class of medicines as ibuprofen for humans.
Metacam is available as an oral suspension (syrup) and as a solution for injection. Your vet will typically prescribe it for:
- Osteoarthritis and chronic joint pain
- Inflammation following surgery
- Acute injuries
- Fever
The active ingredient inhibits certain enzymes (COX-2) that are responsible for inflammation and the sensation of pain. The result: your dog experiences less pain and can move around more easily again.
That sounds good at first. But there’s a downside.
Side effects – what you need to know
Metacam interferes with the body’s natural processes. The enzymes it inhibits also have protective functions – particularly for the stomach, kidneys and liver. That’s why problems can arise when taking it.
Gastrointestinal tract
The most common side effect. COX inhibitors reduce the protective mucous layer in the stomach. This can lead to:
- Vomiting (sometimes with blood)
- Diarrhoea or dark, tarry stools
- Loss of appetite
- Stomach ulcers with long-term use
If your dog vomits or refuses to eat after being given Metacam, take them to the vet immediately.
Kidneys
Meloxicam affects blood flow to the kidneys. In healthy dogs, this is usually not a problem. However, in older dogs – precisely those most commonly given Metacam – kidney function may already be impaired.
That is why vets recommend a blood test including kidney function tests before long-term treatment. Regular check-ups are also advised during treatment.
Liver
Less common, but possible: elevated liver enzyme levels. Your dog may appear lethargic, eat less or have a yellowish discolouration of the mucous membranes. Here too, you should have a blood test carried out.
What many people don’t know
Metacam must never be given together with other NSAIDs or cortisone. This combination can cause life-threatening stomach bleeding. Particular caution is also required for dogs with heart problems, blood clotting disorders or dehydration.
Dosage – less is often more
The standard dosage is 0.1 mg per kilogram of body weight per day. On the first day, your vet will often prescribe double the dose as a starting dose (0.2 mg/kg).
Important rules:
- Always give it with food – this protects the stomach
- Never increase the dose yourself – even if it doesn’t seem to be working
- Never stop treatment abruptly during long-term use – taper it off slowly
- Online dosage calculators are no substitute for your vet
The dosage depends on weight, age, kidney function and any underlying conditions. Your vet knows your dog – Google doesn’t.
The fundamental problem with painkillers
Metacam helps your dog feel better. But it does nothing to address the underlying cause. The cartilage continues to break down. The joints do not improve. The inflammation returns as soon as you stop giving the medication.
This isn’t an argument against Metacam. Acute pain must be treated. No dog should suffer because its owner insists on ‘natural’ remedies.
But it is a reason to think differently in the long term. The question isn’t ‘Metacam: yes or no?’ – but ‘What else can I do to ensure my dog needs less of it?’
Long-term support – what the research says
Certain natural active ingredients can support your dog’s joint health from within. They are no substitute for a visit to the vet or acute pain relief. But they can help ensure your dog experiences fewer symptoms in the long term.
Green-lipped mussel (Perna canaliculus)
A mussel native to New Zealand containing natural omega-3 fatty acids and glycosaminoglycans. Studies show it has anti-inflammatory properties – without the side effects of NSAIDs. It supports cartilage metabolism and can improve synovial fluid.
Glucosamine and chondroitin
The building blocks of joint cartilage. Your dog produces these naturally – but in decreasing amounts as it gets older. Supplementing these from an external source can slow down cartilage breakdown and support regeneration.
MSM (methylsulfonylmethane)
Organic sulphur involved in the formation of collagen and connective tissue. It also has anti-inflammatory properties. Well tolerated and suitable for long-term use.
Devil’s claw and ginger
Herbal anti-inflammatories with a long history of use. Devil’s claw (Harpagophytum) is used in veterinary medicine to treat chronic joint problems. Ginger can reduce swelling and promote blood circulation.
A combination of these active ingredients – such as in Veddelholzer Joint Tablets – can serve as a daily foundation. Many dog owners report that their dogs become noticeably more mobile after a few weeks. Some are able to reduce the Metacam dose in consultation with their vet.
Important: Never stop giving Metacam on your own initiative. Discuss any changes with your vet.
How does the cost of Metacam compare?
A look at the monthly costs helps to put things into perspective:
- Metacam suspension: approx. €15–30 per month (depending on the dog’s size) – plus regular blood tests (€50–100)
- Librela injection: approx. €80–120 per month
- Gold implant: €800–2,000 (one-off cost)
- Surgery (e.g. for hip dysplasia): €1,500–5,000
- Natural joint tablets: approx. 20–30 € per month – no blood tests required
The most affordable option is often the wisest approach: daily dietary supplements as a foundation, and painkillers only when absolutely necessary.
Weaning off Metacam – here’s how to do it properly
If your vet agrees, Metacam can be tapered off gradually. The typical approach:
- Have a blood count carried out – check kidney and liver function
- Start the dietary supplement – at least 4–6 weeks before stopping the medication, to allow the active ingredients to build up
- Slowly reduce the dose – e.g. from daily to every other day
- Adjust exercise – regularly, but without overdoing it
- Monitor your pet – if pain returns, adjust the dose again
Patience is key. Natural active ingredients take time to take full effect. But they do not put strain on the organs.
FAQ
How long can a dog take Metacam?
There is no fixed upper limit – some dogs take Metacam for years. However, the longer the treatment, the more important it is to have regular blood tests (every 3–6 months). Your vet will decide whether the kidney and liver function results allow treatment to continue.
Can I give Metacam and joint tablets at the same time?
Yes. Natural dietary supplements such as green-lipped mussel, glucosamine or MSM have no known interactions with Metacam. Many vets even recommend the combination so that the Metacam dose can be reduced in the long term.
What are the signs that my dog is intolerant to Metacam?
Vomiting, diarrhoea (particularly dark or bloody), loss of appetite, increased thirst, lethargy or yellowish mucous membranes. If these symptoms occur, stop giving Metacam immediately and take your dog to the vet.
Is there a herbal painkiller that can be used as an alternative to Metacam?
No herbal remedy works as quickly or as effectively as Metacam for acute pain. However, devil’s claw, green-lipped mussel and MSM can have an anti-inflammatory effect on chronic conditions – without the side effects on the stomach, liver and kidneys. For acute situations, the vet remains the first point of contact.
How much does Metacam cost for dogs?
The suspension (15 ml) costs approx. €15–20. Depending on the dog’s size, one bottle lasts 2–6 weeks. On top of this, there are vet’s fees for the prescription and regular blood tests – totalling approx. €30–50 per month.
Is Metacam available on prescription only?
Yes. Metacam is available on prescription only and can only be obtained from a vet or from a pharmacy with a vet’s prescription. Joint supplements, on the other hand, are available over the counter.
When to see the vet
Metacam is a prescription-only medicine – so you always need a vet’s prescription for it. However, there are situations where you must go straight to the vet:
- Your dog is vomiting after being given Metacam (especially if there is blood in the vomit)
- Dark, tarry stools
- Your dog is drinking noticeably too much or too little
- Sudden lethargy or refusal to eat
- Yellowish discolouration of the mucous membranes (liver!)
- You have accidentally given too high a dose
And as a general rule: before you change anything about the medication, consult your vet. No blog post can replace a professional examination.
