When your dog is prescribed Metacam for joint pain or inflammation, understanding the potential side effects helps you provide the safest possible care. Metacam (meloxicam) is one of the most commonly prescribed NSAIDs for dogs in the UK, particularly effective for conditions like osteoarthritis and post-surgical pain management.
Whilst most dogs tolerate Metacam well, being aware of what to watch for ensures you can spot any problems early and seek appropriate veterinary guidance. This knowledge empowers you to work confidently with your vet team whilst keeping your dog comfortable and safe.
Understanding both common and serious side effects, along with proper administration guidelines, helps you make informed decisions about your dog's pain management alongside your veterinary care.

What is Metacam and How Does it Work?
Metacam is the brand name for meloxicam, a prescription-only NSAID that veterinary surgeons commonly prescribe for moderate to severe pain and inflammation in dogs. The medication works by blocking COX-2 enzymes, which play a key role in producing prostaglandins, substances that contribute to inflammation, pain, swelling, and fever.
Vets typically prescribe Metacam for osteoarthritis, severe joint pain, post-surgical pain management, and other bone, joint, and tissue-related conditions. The medication usually comes as a flavoured liquid that can be added to food or given directly into your dog's mouth after eating, though tablet forms are sometimes prescribed.
The dosage varies depending on your dog's breed, size, age, and other health conditions. Your vet will calculate the precise amount needed and provide specific instructions for safe administration.
Common Side Effects to Monitor
Most dogs tolerate NSAIDs well, but side effects can occur and owners should watch for warning signs. The PDSA notes that NSAID side effects are generally uncommon and usually mild, typically resolving once the medication is stopped.
Gastrointestinal Issues
The most common side effects affect the digestive system. Watch for stomach upset or nausea, vomiting, diarrhoea, and loss of appetite. More seriously, stomach ulcers can develop, particularly with overdose or in dogs with existing stomach problems.
These digestive issues occur because NSAIDs can affect the protective lining of the stomach and intestines. Always give Metacam with food unless your vet specifically advises otherwise, as this helps protect the stomach lining.
Other Common Signs
Additional signs to monitor include increased thirst and urination, lethargy, and changes in behaviour. These symptoms may indicate your dog's body is responding to the medication in ways that require veterinary attention.
Keep a simple diary of your dog's eating, drinking, and toilet habits during the first few days of treatment. This helps you spot patterns and provides useful information for your vet if concerns arise.
Serious Side Effects Requiring Immediate Veterinary Attention
Whilst serious side effects are uncommon, recognising the warning signs of Metacam poisoning or overdose is crucial for your dog's safety. Contact your vet immediately if your dog shows any combination of these symptoms.
Metacam Side Effect Severity Guide
Mild Digestive Upset
Slight stomach upset, reduced appetite, or mild lethargy. Continue medication but monitor closely and contact your vet if symptoms worsen.
Persistent Symptoms
Ongoing vomiting, diarrhoea, or significant behaviour changes. Stop medication and seek veterinary advice within 24 hours.
Severe Reactions
Bloody vomit or stools, extreme lethargy, difficulty breathing, seizures, or yellowing of eyes or skin. Seek immediate emergency veterinary care.
Severe Gastrointestinal Problems
Emergency signs include extreme abdominal pain, bloody stools or vomit, persistent vomiting and diarrhoea, and signs of stomach ulcers or intestinal bleeding. These symptoms suggest serious damage to the digestive tract that requires immediate intervention.
Kidney and Liver Damage Indicators
Watch for excessive thirst and urination combined with severe lethargy and complete loss of appetite, which may indicate kidney damage. Liver damage signs include yellowing of skin, eyes, or ear tips, persistent vomiting, and extreme lethargy.
Both kidney and liver damage can be serious complications of NSAID use, particularly in dogs with pre-existing conditions or those receiving inappropriate doses.
Neurological and Respiratory Symptoms
Serious neurological symptoms include seizures, lack of coordination, and disorientation. Difficulty breathing is another emergency sign that requires immediate veterinary attention.
If your dog displays any combination of these severe symptoms, treat it as a veterinary emergency and contact your vet or emergency clinic immediately.
Risk Factors and Safe Administration
Understanding which dogs are at higher risk helps prevent complications. According to PDSA guidance, NSAIDs shouldn't be given to dogs with certain conditions and should be used very carefully in pets with kidney, liver, or gut disease.
Higher Risk Situations
Overdosing is particularly common with liquid formulations when proper dosage droppers aren't used. Long-term use, dogs with existing stomach, kidney, or liver problems, and dehydrated animals all face increased risks.
Never give multiple NSAIDs simultaneously unless specifically directed by your vet, as this significantly increases the risk of serious side effects.
Dosage Safety Guidelines
Only use the exact dosage prescribed by your vet and never estimate liquid doses. Always use the proper dosage dropper provided. Never double up on missed doses, and if you miss more than one dose, contact your vet for advice.
Always give NSAIDs with food unless specifically advised otherwise by your vet. If your dog refuses to eat when medication is due, contact your vet for guidance rather than giving the medication on an empty stomach.
What to Do If Problems Occur
If side effects occur, stop the medication immediately and contact your vet for advice. In severe cases, treat the situation as an emergency and seek immediate veterinary care.
Most dogs that react to one NSAID can tolerate a different type or brand, so don't assume your dog can never have anti-inflammatory medication again. Your vet can discuss alternative options if needed.
Never give human NSAIDs like ibuprofen or naproxen to dogs, as these are highly toxic to animals. Contact your vet or animal poison line immediately if your dog accidentally consumes human painkillers.
Alternative and Complementary Approaches
Whilst NSAIDs remain the standard veterinary treatment for inflammation and pain, some owners explore complementary approaches alongside veterinary care. Always discuss any alternatives with your vet first to ensure they're appropriate for your dog's specific condition.
Physical Therapies
Hydrotherapy and specialist swimming classes can provide low-impact exercise that supports joint health. Underwater treadmill sessions offer controlled movement that many dogs find beneficial.
Acupuncture is recommended by many vets as alternative pain relief and can work alongside conventional treatments to support your dog's comfort and mobility.
Nutritional Support
Joint supplements containing natural ingredients may provide complementary support for dogs managing joint conditions. MedPaw's hip and joint supplement works as a complementary feed alongside veterinary care, not as a replacement for prescribed medication when it's medically necessary.
Beneficial ingredients include glucosamine and chondroitin, which help form cartilage building blocks, and omega-3 fatty acids that can help reduce inflammation. Other supportive ingredients may include MSM, hyaluronic acid, and Boswellia serrata, each offering different mechanisms of joint support.
Long-term Considerations and Monitoring
Dogs on long-term NSAIDs require careful monitoring as prolonged use can impact kidney function. However, vets often determine that the benefits outweigh potential risks for chronic conditions like severe arthritis.
Your vet may recommend regular blood tests to monitor organ function during extended NSAID therapy. These check-ups help catch any developing problems early and ensure the medication remains safe for your dog's continued use.
Regular monitoring also allows your vet to assess whether the current treatment plan is still the most appropriate option or whether adjustments might benefit your dog's long-term health and comfort.
When to Consult Your Vet
Seek immediate veterinary attention for any signs of overdose or poisoning, severe gastrointestinal upset, difficulty breathing, or neurological symptoms. Don't wait to see if symptoms improve on their own when dealing with potential NSAID complications.
Schedule routine consultations if you're concerned about side effects, want to discuss alternatives to NSAIDs, or need regular monitoring during long-term use. Your vet can also advise on whether complementary approaches might benefit your dog's overall joint health strategy.
Prepare questions about why this specific NSAID was chosen for your dog, expected duration of treatment, warning signs specific to your dog's condition, and whether complementary approaches might be beneficial alongside the prescribed medication.
Supporting Your Dog's Joint Health Safely
Metacam is a valuable medication that helps many dogs manage pain and inflammation effectively. Whilst side effects can occur, they're generally uncommon and manageable when the medication is used correctly under veterinary supervision.
The key to safe use lies in following dosage instructions precisely, monitoring your dog closely for any changes, and maintaining open communication with your vet. Never use human medications and seek immediate help if serious side effects occur.
Managing your dog's joint health often involves a comprehensive approach combining veterinary medication when necessary, appropriate exercise, weight management, and potentially complementary nutritional support. All coordinated with your veterinary team to ensure the safest and most effective care for your dog's individual needs.
How quickly do Metacam side effects appear in dogs?
Side effects from Metacam can appear within hours of the first dose, though they may also develop after several days of treatment. Mild digestive upset like reduced appetite or slight nausea often occurs within the first 24-48 hours. More serious reactions can develop at any time during treatment, which is why it's important to monitor your dog closely throughout the entire course of medication and contact your vet if you notice any concerning changes.
Can I give my dog natural joint supplements alongside Metacam?
You should always discuss any supplements with your vet before giving them alongside Metacam or any prescribed medication. Many natural joint supplements containing ingredients like glucosamine, chondroitin, and omega-3 fatty acids work as complementary feeds to support joint health, but your vet needs to ensure there are no interactions with your dog's prescribed treatment. They can advise whether additional nutritional support might be beneficial for your dog's specific condition.
What should I do if I accidentally gave my dog too much Metacam?
Contact your vet or emergency veterinary clinic immediately if you've given your dog more Metacam than prescribed. Overdose can cause serious side effects including severe stomach upset, kidney damage, or liver problems. Don't wait to see if symptoms develop - early intervention is crucial for the best outcome. Have the medication packaging ready so you can tell your vet exactly how much was given and when.
Are some dog breeds more likely to have Metacam side effects?
Whilst any dog can experience side effects, older dogs and those with existing kidney, liver, or stomach problems are at higher risk regardless of breed. Dogs that are dehydrated or taking multiple medications may also be more susceptible to complications. Your vet will assess your individual dog's health status and risk factors before prescribing Metacam, and may recommend blood tests to check organ function before starting treatment.
How long can dogs safely take Metacam for arthritis?
The duration of Metacam treatment depends on your dog's individual condition and response to the medication. Some dogs with chronic arthritis may need long-term treatment, whilst others might only require short courses. Your vet will monitor your dog regularly during extended treatment, often recommending blood tests to check kidney and liver function. If you have concerns about long-term use, discuss alternative pain management strategies with your vet.
