Comprehensive Tables for Metacam Dosage in Cats
Below are detailed tables showing Metacam dosages based on weight and concentration, designed for practical veterinary use.
| Cat Weight (kg) | Recommended Dose (mg/kg) | Total Dose (mg) | Oral Suspension Volume (mL) @ 1.5 mg/mL | Injection Volume (mL) @ 5 mg/mL |
|---|---|---|---|---|
| 2.0 | 0.1 | 0.2 | 0.13 | 0.04 |
| 3.0 | 0.1 | 0.3 | 0.20 | 0.06 |
| 4.0 | 0.1 | 0.4 | 0.27 | 0.08 |
| 5.0 | 0.1 | 0.5 | 0.33 | 0.10 |
| 6.0 | 0.1 | 0.6 | 0.40 | 0.12 |
| 7.0 | 0.1 | 0.7 | 0.47 | 0.14 |
| 8.0 | 0.1 | 0.8 | 0.53 | 0.16 |
Metacam Dosage Frequency and Administration Guidelines
| Dosage Regimen | Dose (mg/kg) | Frequency | Route | Notes |
|---|---|---|---|---|
| Initial Dose | 0.1 mg/kg | Once daily | Oral or Injection | Start of therapy |
| Maintenance Dose | 0.05 mg/kg | Once daily | Oral | After initial 3 days |
| Alternative Regimen | 0.05 mg/kg | Twice daily | Oral | For severe pain |
Formulas for Metacam Dosage Calculation in Cats
Understanding the formulas behind Metacam dosing ensures precise and safe administration tailored to each cat’s needs.
1. Basic Dose Calculation
The fundamental formula to calculate the total Metacam dose (in mg) based on the cat’s weight and recommended dose per kilogram is:
- Weight (kg): The body weight of the cat in kilograms.
- Dose (mg/kg): The prescribed Metacam dose per kilogram, typically 0.05 to 0.1 mg/kg.
2. Volume of Oral Suspension to Administer
To convert the total dose in mg to the volume of oral suspension (mL), use the concentration of the suspension:
- Total Dose (mg): Calculated from the previous formula.
- Concentration (mg/mL): The strength of the oral suspension, commonly 1.5 mg/mL for Metacam.
3. Volume of Injectable Metacam to Administer
For injectable Metacam, the volume is calculated similarly, but the concentration differs:
- Injection Concentration (mg/mL): Typically 5 mg/mL for Metacam injectable solution.
4. Adjusted Dose for Frequency Changes
If the dosing frequency changes (e.g., from once daily to twice daily), the dose per administration is adjusted accordingly:
- Total Daily Dose (mg/kg): The total amount prescribed per day.
- Number of Doses per Day: Frequency of administration (e.g., 1 or 2).
Detailed Real-World Examples of Metacam Dosage Calculation for Cats
Example 1: Oral Metacam Dose for a 4.5 kg Cat at 0.1 mg/kg Once Daily
Step 1: Calculate the total dose in mg.
Step 2: Calculate the volume of oral suspension to administer, assuming 1.5 mg/mL concentration.
Step 3: Administer 0.3 mL of Metacam oral suspension once daily.
This precise dosing ensures effective pain relief while minimizing overdose risk.
Example 2: Injectable Metacam Dose for a 6.8 kg Cat at 0.3 mg/kg Subcutaneously
Step 1: Calculate the total dose in mg.
Step 2: Calculate the volume of injectable Metacam to administer, assuming 5 mg/mL concentration.
Step 3: Administer approximately 0.41 mL subcutaneously as a single dose.
Accurate volume measurement is critical to avoid adverse effects and ensure therapeutic efficacy.
Additional Technical Considerations for Metacam Dosage in Cats
- Pharmacokinetics: Metacam (meloxicam) has a half-life of approximately 15 hours in cats, supporting once-daily dosing.
- Renal and Hepatic Function: Dose adjustments may be necessary in cats with compromised kidney or liver function.
- Administration Route: Oral dosing is preferred for long-term therapy; injectable forms are used for initial or acute pain management.
- Monitoring: Regular veterinary monitoring is essential to detect adverse reactions such as gastrointestinal upset or renal impairment.
- Formulation Variability: Always verify the concentration of the Metacam product used, as formulations may vary by manufacturer and region.
Summary of Official Guidelines and References
According to the FDA-approved Metacam label and veterinary pharmacology texts, the recommended initial dose for cats is 0.1 mg/kg once daily, followed by a maintenance dose of 0.05 mg/kg once daily. The injectable form is typically dosed at 0.3 mg/kg subcutaneously for acute pain.
