Canine Metacam (Meloxicam): Complete Prescription Drug Guide

If your dog has been prescribed Metacam, you likely have questions about what it does, how long your dog needs it, and what side effects to watch for. Metacam — the brand name for the generic drug meloxicam — is one of the most widely prescribed nonsteroidal anti-inflammatory drugs (NSAIDs) in veterinary medicine. According to the U.S. Food and Drug Administration, meloxicam was approved for veterinary use in dogs in 2003 and has since become a cornerstone of pain management in canine patients.

This guide covers everything from how Metacam works at the cellular level to real-world cost expectations in 2026, so you can feel confident managing your dog's treatment plan alongside your veterinarian.

What Is Canine Metacam and What Is It Used For?

Metacam is the trade name for meloxicam, a nonsteroidal anti-inflammatory drug (NSAID) manufactured by Boehringer Ingelheim for veterinary use. It belongs to the oxicam class of NSAIDs and is specifically formulated for dogs in an oral suspension (1.5 mg/mL) and chewable tablet forms.

FDA-Approved Veterinary Uses

• Osteoarthritis pain and inflammation: Long-term management of chronic joint pain in dogs with degenerative joint disease, hip dysplasia, or other arthritic conditions
• Post-surgical pain and inflammation: Short-term control of pain and swelling following orthopedic or soft tissue surgery (typically 3–5 days post-operatively)

Common Off-Label Uses (Veterinary-Directed)

Your veterinarian may prescribe Metacam for conditions beyond its FDA-approved label. These off-label uses are legal and common in veterinary practice when a vet determines the benefit outweighs the risk:

• Acute musculoskeletal injuries (sprains, strains, soft tissue trauma)
• Dental procedure pain management (post-extraction)
• Acute back pain or intervertebral disc disease (IVDD) flare-ups
• Cancer-related pain as part of a multimodal pain protocol
• Post-injury inflammation from trauma or bite wounds

Off-label use should always be explicitly directed by your veterinarian, who will adjust the dosage and monitoring schedule accordingly.

How Does Metacam Work in Dogs?

Meloxicam works by inhibiting cyclooxygenase enzymes (COX-1 and COX-2), which are responsible for converting arachidonic acid into prostaglandins. Prostaglandins are lipid compounds produced at sites of tissue damage that trigger inflammation, pain signaling, and fever.

What makes meloxicam notable among veterinary NSAIDs is its preferential COX-2 inhibition. At therapeutic doses, it inhibits COX-2 (the enzyme primarily associated with inflammation) more strongly than COX-1 (the enzyme responsible for maintaining protective stomach lining and kidney blood flow). This preferential selectivity is one reason meloxicam has a relatively favorable safety profile compared to older, non-selective NSAIDs — though it is not without risk, particularly at higher doses or with prolonged use.

Pharmacokinetics in dogs:

• Onset of action: Peak blood levels reached within 7–8 hours after oral administration
• Half-life: Approximately 24 hours in dogs (allows once-daily dosing)
• Metabolism: Hepatic (liver) metabolism via cytochrome P450 enzymes
• Elimination: Primarily through feces (approximately 75%), with remainder through urine
• Bioavailability: Nearly 100% when given orally — food does not significantly affect absorption

Typical Metacam Dosage for Dogs by Condition

Condition	Loading Dose (Day 1)	Maintenance Dose (Day 2+)	Typical Duration
Osteoarthritis (chronic)	0.09 mg/lb (0.2 mg/kg) once	0.045 mg/lb (0.1 mg/kg) once daily	Long-term (months to years, with monitoring)
Post-surgical pain	0.09 mg/lb (0.2 mg/kg) once	0.045 mg/lb (0.1 mg/kg) once daily	3–5 days post-operatively
Acute injury (off-label)	0.09 mg/lb (0.2 mg/kg) once	0.045 mg/lb (0.1 mg/kg) once daily	5–10 days, vet-directed
Cancer pain (off-label)	0.09 mg/lb (0.2 mg/kg) once	0.045 mg/lb (0.1 mg/kg) once daily	Long-term, as part of multimodal protocol

Dosage Calculation Example

For a 50 lb (22.7 kg) dog with osteoarthritis:

• Day 1 loading dose: 50 lb × 0.09 mg/lb = 4.5 mg (or 22.7 kg × 0.2 mg/kg = 4.54 mg)
• Day 2+ maintenance: 50 lb × 0.045 mg/lb = 2.25 mg once daily
• Using the 1.5 mg/mL oral suspension: maintenance dose = 2.25 mg ÷ 1.5 mg/mL = 1.5 mL

Metacam oral suspension comes with a calibrated dosing syringe marked in weight increments. Always use the syringe provided with the medication — kitchen measuring spoons are not accurate enough for veterinary drug dosing.

How to Administer Metacam to Your Dog

Proper administration affects both the drug's effectiveness and your dog's gastrointestinal safety.

Oral Suspension (1.5 mg/mL)

1. Shake the bottle well before each use — the suspension can settle
2. Attach the calibrated dosing syringe to the bottle adapter
3. Draw up the exact volume prescribed by your veterinarian
4. Administer directly into your dog's mouth, aiming toward the back of the tongue, or mix into a small amount of food
5. Wipe the syringe clean after each use — do not wash with water, as moisture can degrade remaining medication

Chewable Tablets

Metacam also comes in chewable tablet form (available in 1.0 mg and 2.5 mg strengths). These are beef-flavored and most dogs accept them readily. They can be given as a treat or hidden in a pill pocket.

Administration Best Practices

• Give with food: While Metacam can technically be given on an empty stomach, giving it with a meal significantly reduces the risk of gastrointestinal irritation and ulceration. This is strongly recommended.
• Consistent timing: Give at approximately the same time each day to maintain steady blood levels
• Ensure hydration: Your dog must have access to fresh water at all times. Dehydration increases the risk of kidney damage from NSAIDs
• Do not split doses: Metacam is designed for once-daily dosing. Do not give half-doses twice daily unless your vet specifically instructs this

Metacam Side Effects: What to Watch For

Like all NSAIDs, Metacam carries a risk of side effects. Most dogs tolerate it well at prescribed doses, but awareness of both common and serious reactions is essential for safe use.

Side Effect	Estimated Frequency	What to Do
Decreased appetite	5–10%	Monitor; try giving with food. Contact vet if persists >2 days
Vomiting (mild)	3–8%	Ensure medication is given with food. Contact vet if recurrent
Diarrhea or soft stools	3–5%	Monitor stool consistency. Contact vet if bloody or persists >48 hours
Lethargy / behavioral changes	2–5%	Note timing relative to dosing. Report to vet at next visit
Vomiting blood or dark/tarry stools	<1–2%	STOP medication. Contact vet or emergency clinic immediately
Increased thirst and urination	<1–2%	STOP medication. Contact vet — possible kidney involvement
Yellowing of gums, eyes, or skin (jaundice)	<1%	STOP medication. Emergency vet visit — possible liver toxicity
Incoordination, seizures, or collapse	Rare (<0.5%)	Emergency — seek immediate veterinary care

Contraindications: Dogs Who Should NOT Receive Metacam

Metacam is not appropriate for every dog. Your veterinarian will screen for these contraindications before prescribing:

• Known hypersensitivity to meloxicam or other NSAIDs — dogs with a history of allergic reaction to carprofen, deracoxib, or aspirin may cross-react
• Pre-existing kidney disease — NSAIDs reduce renal blood flow and can worsen chronic kidney disease (CKD) or trigger acute kidney injury
• Pre-existing liver disease — impaired hepatic function reduces the liver's ability to metabolize meloxicam, increasing toxicity risk
• Active gastrointestinal ulceration or bleeding — NSAIDs further compromise the stomach lining
• Dehydrated or hypovolemic dogs — reduced blood volume amplifies the kidney-damaging effects of NSAIDs
• Dogs with bleeding disorders — NSAIDs inhibit platelet function, which can worsen coagulopathies
• Pregnant or nursing dogs — safety has not been established in breeding, pregnant, or lactating dogs
• Puppies under 6 months of age — safety has not been established in young puppies
• Dogs currently receiving corticosteroids — concurrent use of steroids (prednisone, dexamethasone) with NSAIDs dramatically increases GI ulceration risk and is contraindicated

Drug Interactions: Medications That Conflict With Metacam

Drug interactions are one of the most common causes of NSAID-related adverse events. Always provide your veterinarian with a complete list of every medication, supplement, and over-the-counter product your dog receives.

Drug / Supplement	Interaction Type	Risk Level	Veterinary Guidance
Corticosteroids (prednisone, dexamethasone, prednisolone)	Synergistic GI damage — dramatically increased ulceration and perforation risk	HIGH — Contraindicated	Never combine. A washout period of 5–7 days between stopping a steroid and starting Metacam is typically required
Other NSAIDs (carprofen, deracoxib, aspirin, firocoxib)	Additive toxicity — increased risk of GI bleeding, kidney damage	HIGH — Contraindicated	Never combine. Washout period of 5–7 days between different NSAIDs
ACE inhibitors (enalapril, benazepril)	NSAIDs reduce renal prostaglandin production, potentially reducing efficacy of ACE inhibitors and increasing kidney strain	MODERATE	Can be used together with close kidney monitoring (bloodwork every 3–6 months)
Diuretics (furosemide/Lasix)	NSAIDs reduce kidney blood flow; combined with diuretic-induced fluid loss, kidney injury risk increases	MODERATE	Use with caution. Ensure adequate hydration. Monitor renal values frequently
Aminoglycoside antibiotics (gentamicin, amikacin)	Both drugs are nephrotoxic — combined use significantly increases kidney damage risk	MODERATE–HIGH	Avoid concurrent use if possible. If necessary, aggressive IV fluid support and daily kidney monitoring
Methotrexate	NSAIDs reduce renal clearance of methotrexate, increasing toxicity	MODERATE	Rarely used in dogs; if applicable, vet will adjust methotrexate dose and monitor closely
Joint supplements (glucosamine, chondroitin, fish oil)	Generally safe and often used together as part of multimodal arthritis management. High-dose fish oil may have mild additive anti-platelet effect	LOW	Safe to combine. Inform your vet of all supplements

Monitoring Requirements for Dogs on Metacam

One of the most important aspects of long-term Metacam use is consistent veterinary monitoring. NSAIDs can cause silent damage to the kidneys, liver, and gastrointestinal tract — damage that is only detectable through blood work and urinalysis before clinical symptoms appear.

Expected monitoring costs (2026 estimates):

• Baseline blood work + urinalysis: $150–$250
• Each recheck panel: $120–$200
• SDMA add-on: $40–$60
• Annual monitoring cost for a dog on long-term Metacam: approximately $240–$500 (2–3 recheck panels per year)

These costs are an investment in preventing catastrophic organ damage. Dogs on long-term NSAID therapy without monitoring are at significantly higher risk for undetected kidney or liver disease progression.

How Long Does My Dog Need to Be on Metacam?

The duration of Metacam therapy depends entirely on the condition being treated:

• Post-surgical pain: Typically 3–5 days. Your vet will taper or discontinue as surgical pain resolves.
• Acute injury: Usually 5–10 days, reassessed at a follow-up visit.
• Osteoarthritis: Often long-term or lifelong. Many dogs with chronic arthritis remain on Metacam for years with appropriate monitoring. Your vet may periodically attempt dose reduction to find the minimum effective dose.
• Cancer pain management: Duration depends on the cancer treatment plan and may continue alongside other pain modalities.

For chronic conditions, your veterinarian may recommend a "lowest effective dose" strategy — starting at the standard maintenance dose and gradually reducing if pain control is maintained. Some dogs do well at doses slightly below the standard 0.1 mg/kg, while others require the full dose. Never reduce the dose on your own — work with your vet to find the right balance between pain control and side effect risk.

It's also common for vets to implement "drug holidays" — brief periods where Metacam is paused (under veterinary guidance) to assess whether the dog still needs the medication or to give the kidneys and liver a rest. This is only appropriate for stable, chronic patients and should never be attempted without veterinary instruction.

Cost of Metacam and Generic Availability

Metacam is available as both the brand-name product and as generic meloxicam oral suspension, which can significantly reduce costs.

Product	Form / Strength	Typical Price Range (2026)	Notes
Brand-name Metacam (Boehringer Ingelheim)	Oral suspension 1.5 mg/mL, 32 mL bottle	$55–$85	Includes calibrated dosing syringe
Brand-name Metacam	Oral suspension 1.5 mg/mL, 100 mL bottle	$110–$160	More cost-effective for large dogs or long-term use
Generic meloxicam (various manufacturers)	Oral suspension 1.5 mg/mL, 32 mL	$30–$55	Bioequivalent to brand-name. Ask your vet about generic substitution
Metacam chewable tablets	1.0 mg or 2.5 mg, 30-count	$45–$80	Convenient for dogs that resist liquid medication

Cost-saving tips:

• Ask your veterinarian if generic meloxicam is appropriate — the FDA requires generics to demonstrate bioequivalence
• For large dogs on long-term therapy, the 100 mL bottle offers better per-dose pricing
• Some online veterinary pharmacies (such as Chewy Pharmacy or 1-800-PetMeds) offer competitive pricing with a valid prescription — always verify the pharmacy is Vet-VIPPS accredited
• Pet insurance plans with prescription drug coverage may reimburse a portion of Metacam costs

Missed Dose and Overdose: What to Do

If You Miss a Dose

• Give the missed dose as soon as you remember — unless it is close to the next scheduled dose
• If it is within 4–6 hours of the next dose, skip the missed dose entirely and resume the normal schedule
• Never double the dose to make up for a missed one — this significantly increases the risk of GI ulceration and kidney damage
• If you miss more than 2 consecutive days, contact your veterinarian before resuming — they may want to reassess or restart at the loading dose

If an Overdose Occurs

Meloxicam overdose in dogs is a medical emergency. Even a dose 2–3 times the prescribed amount can cause serious gastrointestinal ulceration, acute kidney failure, or liver damage.

Signs of overdose include:

• Severe or repeated vomiting (potentially with blood)
• Profuse diarrhea, possibly bloody or black/tarry
• Extreme lethargy or unresponsiveness
• Seizures
• Abdominal pain (hunched posture, whining when touched)
• Excessive drooling
• Pale gums (indicating internal bleeding or shock)

Immediate actions:

1. Do NOT induce vomiting unless specifically instructed by a veterinarian — vomiting can worsen esophageal damage from the drug
2. Contact your veterinarian or nearest emergency veterinary clinic immediately
3. Call the ASPCA Animal Poison Control Center at (888) 426-4435 (available 24/7, a consultation fee of approximately $95 applies)
4. Bring the Metacam bottle with you to the clinic so the vet can confirm the concentration and estimate the ingested dose

Emergency treatment may include IV fluids to protect the kidneys, gastroprotectant medications (such as misoprostol, sucralfate, or omeprazole), activated charcoal to absorb remaining drug, and in severe cases, blood transfusions for GI hemorrhage. The prognosis for overdose depends on the amount ingested, the speed of treatment, and the dog's baseline organ function.

Alternatives to Metacam for Pain Management in Dogs

Metacam is effective for many dogs, but it isn't the only option. Depending on your dog's condition, health status, and tolerance, your veterinarian may recommend one of these alternatives:

Alternative	Drug Class	Best For	Key Considerations
Carprofen (Rimadyl)	NSAID (propionic acid class)	Osteoarthritis, post-surgical pain	Similar efficacy to Metacam. Some dogs tolerate one NSAID better than another. Available as chewable tablets and injectable
Deracoxib (Deramaxx)	NSAID (COX-2 selective, coxib class)	Post-surgical pain, osteoarthritis	More COX-2 selective than meloxicam. May be preferred for dogs with mild GI sensitivity to other NSAIDs
Firocoxib (Previcox)	NSAID (COX-2 selective, coxib class)	Osteoarthritis, dental pain	Available as chewable tablet. Once-daily dosing
Grapiprant (Galliprant)	Non-NSAID anti-inflammatory (EP4 receptor antagonist)	Osteoarthritis pain in dogs who cannot tolerate NSAIDs	Different mechanism — blocks prostaglandin E2 receptor rather than COX enzymes. Fewer GI and kidney side effects. Typically more expensive ($80–$150/month)
Tramadol	Opioid analgesic	Moderate to severe pain, often as adjunct to NSAIDs	Not anti-inflammatory. Variable efficacy in dogs (recent studies show limited standalone benefit). Often used as part of multimodal protocol
Librela (bedinvetmab)	Monoclonal antibody (anti-NGF)	Osteoarthritis pain — monthly injection	Non-NSAID, non-opioid. Administered by vet as monthly subcutaneous injection. Minimal systemic side effects. Cost approximately $50–$120 per injection depending on dog size
Adequan (polysulfated glycosaminoglycan)	Disease-modifying osteoarthritis drug (DMOAD)	Early-stage osteoarthritis, joint cartilage support	Injectable series (typically 8 injections over 4 weeks, then maintenance). Slows cartilage degradation. Not a pain reliever per se, but can reduce NSAID dependency over time

Many veterinarians now use a multimodal pain management approach — combining lower doses of an NSAID like Metacam with joint supplements (omega-3 fatty acids, glucosamine/chondroitin), physical therapy, weight management, and newer therapies like Librela. This strategy often provides superior pain control while reducing the dose-dependent side effects of any single medication.

Frequently Asked Questions About Canine Metacam

Can I give my dog human meloxicam (Mobic)?

No. Human meloxicam (brand name Mobic) comes in tablet strengths of 7.5 mg and 15 mg — far too concentrated for safe canine dosing. The canine formulation (Metacam) is specifically designed at 1.5 mg/mL concentration with a calibrated dosing syringe for precise weight-based dosing. Even attempting to break a human tablet into a canine-appropriate dose risks dangerous inaccuracy. Additionally, the inactive ingredients in human formulations may not be safe for dogs.

My dog has been on Metacam for months — is long-term use safe?

Long-term Metacam use is common and generally safe when accompanied by regular veterinary monitoring. The key is consistent blood work (every 6 months for most dogs, every 3 months for seniors or dogs with pre-existing conditions) to catch any kidney or liver changes early. Many dogs with osteoarthritis remain on Metacam for years with no significant adverse effects. The risk of unmanaged chronic pain — reduced mobility, muscle atrophy, behavioral changes, decreased quality of life — often outweighs the managed risk of long-term NSAID therapy.

Can Metacam be used with gabapentin?

Yes, gabapentin and Metacam are commonly prescribed together as part of a multimodal pain management protocol. Gabapentin works on nerve pain pathways while Metacam addresses inflammatory pain — they complement each other well. Your veterinarian may prescribe this combination for dogs with osteoarthritis, IVDD, or neuropathic pain. Always follow your vet's specific dosing instructions for both medications.

What should I do if my dog refuses to take Metacam?

The oral suspension can be mixed into a small amount of wet food, peanut butter (xylitol-free), or a pill pocket treat. The chewable tablets are beef-flavored and generally well-accepted. If your dog consistently refuses the medication, ask your veterinarian about compounding options — some pharmacies can formulate meloxicam in flavored treats or transdermal gels. Never force-pill a dog in a way that risks aspiration.

Does Metacam cure arthritis?

No. Metacam manages the pain and inflammation associated with arthritis but does not stop or reverse the underlying degenerative joint disease. For disease-modifying effects, your veterinarian may recommend complementary therapies such as Adequan injections, omega-3 fatty acid supplementation, weight management, physical rehabilitation, or surgical intervention for severe cases.

Can I stop Metacam abruptly or do I need to taper?

For short-term use (post-surgical, acute injury), Metacam can typically be stopped abruptly at the end of the prescribed course. For long-term use, some veterinarians recommend a gradual taper — particularly if your dog has been on it for months — to assess whether pain returns and to allow the body to readjust. Always follow your veterinarian's instructions for discontinuation. Never stop and restart without consulting your vet.

This article is for educational purposes only and does not replace professional veterinary advice. Always consult your veterinarian before starting, adjusting, or discontinuing any medication for your dog. Individual dogs may respond differently to Metacam, and only a licensed veterinarian who has examined your dog can determine whether this medication is appropriate for their specific condition.
