Understanding Meloxicam for Cats
Meloxicam belongs to the NSAID class of medications and serves as an effective pain reliever for felines experiencing acute, chronic, or post-surgical discomfort. Veterinarians may prescribe it under brand names including Metacam, Mobic, Vivlodex, or generic meloxicam formulations.
The medication works by reducing inflammation and blocking pain signals, making it particularly useful for musculoskeletal injuries and recovery periods. Unlike some human NSAIDs, meloxicam has been formulated specifically for veterinary use, with concentrations and safety profiles tailored to feline metabolism.
Administration occurs once daily via oral suspension, which many cats tolerate well. The liquid form allows precise dosing adjustments based on individual weight and clinical needs.
Metacam Dosage Calculation
Meloxicam dosing for cats follows straightforward weight-based calculations. The standard prolonged-treatment dose is 0.05 mg/kg once daily. For the first 24 hours, depending on your cat's condition, the initial dose may be higher (0.1β0.2 mg/kg). The most commonly used oral suspension concentration is 0.5 mg/mL.

Dosage Guidelines by Indication
Initial and maintenance doses vary depending on why your veterinarian prescribed meloxicam:
- Post-operative pain: First 24 hours at 0.2 mg/kg (given as a subcutaneous injection before surgery using 2 mg/mL solution), then 0.05 mg/kg daily for maintenance.
- Acute musculoskeletal pain: 0.2 mg/kg for the first 24 hours, followed by 0.05 mg/kg daily.
- Chronic musculoskeletal pain: 0.1 mg/kg for the initial 24 hours, then 0.05 mg/kg daily for ongoing management.
Always follow your veterinarian's specific instructions, as they may adjust dosing based on your cat's response and individual risk factors.
Safety Profile and Side Effects
Meloxicam carries a strong safety record in feline patients, with adverse effects occurring in fewer than 1 in 10,000 cats treated. However, awareness of potential complications allows for early detection and intervention.
Common side effects include loss of appetite, vomiting, and diarrhea. More serious but rare complications can involve gastrointestinal ulceration, faecal occult bleeding (detectable only via stool testing), lethargy, elevated liver enzymes, and renal dysfunction. Allergic reactions, though uncommon, may occur in sensitive individuals.
Your veterinarian may recommend baseline blood work before starting meloxicam, especially in older cats or those with pre-existing kidney disease, to ensure safe use and monitor organ function during treatment.
Key Dosing Considerations
Proper administration of meloxicam requires attention to several practical details.
- Concentration matters β Oral meloxicam suspension for cats is typically 0.5 mg/mL, but post-operative injections use 2 mg/mL. Always verify the concentration on your bottle, as mixing these up could result in incorrect dosing.
- Once-daily timing β Administer meloxicam at the same time each day to maintain consistent drug levels in your cat's bloodstream. Many owners find morning dosing easiest to remember.
- Pharmacokinetics and washout β Meloxicam has a 24-hour half-life; expect half the dose to remain after one day and only a quarter after two days. Complete elimination typically requires over six days, so plan for washout periods if switching medications.
- Monitor kidney function β NSAIDs can affect renal perfusion in cats, especially those with existing kidney disease. Request periodic blood work (serum creatinine and blood urea nitrogen) during prolonged treatment to ensure safety.
