Calculate meloxicam (Metacam) dosage for dogs by weight. Includes initial and maintenance dose, oral suspension measurement, and safety guidelines for canine NSAID therapy.
Metacam (meloxicam) is a non-steroidal anti-inflammatory drug (NSAID) widely prescribed for dogs to manage pain and inflammation associated with osteoarthritis, post-surgical pain, and other musculoskeletal conditions. It is FDA-approved for canine use as an oral suspension (1.5 mg/mL).
The standard canine dosing protocol is an initial loading dose of 0.2 mg/kg on day one, followed by a maintenance dose of 0.1 mg/kg once daily thereafter. Metacam should always be given with food or shortly after eating to reduce the risk of gastrointestinal side effects. The oral suspension comes with a calibrated dosing syringe for accurate measurement.
This calculator provides precise dosing based on your dog's weight, including the volume of oral suspension to administer. While Metacam has a good safety profile when used correctly, NSAIDs require monitoring of kidney and liver function, especially in older dogs or those on long-term therapy. Never administer without veterinary supervision. A written medication log with appetite and stool notes makes side-effect detection faster and safer.
For best results, combine calculator output with direct observation and periodic check-ins with a veterinarian or qualified advisor. Small adjustments made early usually improve comfort, safety, and long-term outcomes more than large corrective changes made later.
Accurate NSAID dosing prevents both underdosing (inadequate pain control) and overdosing (increased toxicity risk). This calculator ensures precise measurement of the oral suspension, which is particularly important for small dogs where the margin is narrow. This dog metacam (meloxicam) dosage calculator helps you compare outcomes quickly and reduce avoidable mistakes when making day-to-day care decisions. Use the estimate as a planning baseline and confirm final decisions with a qualified professional when risk is high.
Loading Dose (Day 1): 0.2 mg/kg. Maintenance Dose (Day 2+): 0.1 mg/kg once daily. Oral Suspension (1.5 mg/mL): Volume (mL) = Dose (mg) ÷ 1.5. Injectable (5 mg/mL): Volume (mL) = Dose (mg) ÷ 5. Round to nearest 0.1 mL for accuracy.
Result: 2.7 mg dose (1.8 mL oral suspension) once daily with food
A 60-lb (27.2 kg) dog at 0.1 mg/kg maintenance needs 2.72 mg per day. Using the 1.5 mg/mL suspension, this is 1.8 mL measured with the dosing syringe. Give once daily with food.
Meloxicam is a preferential COX-2 inhibitor, meaning it primarily blocks cyclooxygenase-2 (the enzyme responsible for pain and inflammation) while having less effect on COX-1 (which protects the GI tract and supports kidney function). This selectivity gives meloxicam a better GI safety profile than non-selective NSAIDs, though GI protection is not complete.
For dogs on ongoing meloxicam, veterinarians recommend: baseline blood work before starting (BUN, creatinine, liver enzymes, CBC), recheck blood work at 2-4 weeks, then every 3-6 months. Watch for: decreased appetite (often the first sign of GI irritation), dark or tarry stool (GI bleeding), increased water consumption (kidney effects), or lethargy. Report any of these to your vet immediately.
(1) Never combine two NSAIDs. (2) Allow 5-7 day washout between different NSAIDs. (3) Do not combine NSAIDs with corticosteroids (e.g., prednisone). (4) Use with caution in dogs with kidney disease, liver disease, GI history, or dehydration. (5) Do not use in puppies under 6 weeks or in pregnant/nursing dogs. (6) If a dose is missed, give it at the next scheduled time — do not double up.
Metacam is primarily used for osteoarthritis pain management, post-surgical inflammation, and acute musculoskeletal pain. It reduces pain, swelling, and stiffness by inhibiting prostaglandin synthesis (COX-2 inhibition).
Human meloxicam tablets (7.5 mg, 15 mg) are too concentrated for most dogs and difficult to split accurately. The veterinary oral suspension (1.5 mg/mL) allows precise dosing. Only use medication prescribed by your vet.
Most common: vomiting, diarrhea, decreased appetite, soft stool. Less common: GI ulceration, liver enzyme elevation, kidney effects. Rare: GI perforation. Report any black/tarry stool, vomiting blood, or sudden lethargy immediately.
Yes, meloxicam is commonly used long-term for osteoarthritis. However, periodic monitoring (blood work every 3-6 months) is recommended to check kidney and liver function. Your vet may adjust the dose to the lowest effective amount.
Always give Metacam with food or shortly after eating. Food helps protect the stomach lining and ensures consistent drug absorption. If your dog refuses food, do not give the medication and contact your vet.
NEVER combine Metacam with other NSAIDs (carprofen, deracoxib, aspirin) — this dramatically increases the risk of GI ulceration and kidney damage. A washout period of 5-7 days is needed when switching NSAIDs. Some non-NSAID pain medications can be combined under veterinary guidance.
