How to Use This Calculator

Enter the dog's weight and select the appropriate unit (kg or lb)
Select the Panacur form you have available (granules, suspension, or paste)
Choose the treatment purpose (type of parasite or general deworming)
Select the treatment duration (1, 3, 5 days, or custom)
Indicate if the dog is pregnant (requires dosage adjustment)
Click Calculate to see the recommended dosage and administration instructions

Formula Used

Daily Dosage (mg) = Dog Weight (kg) × Dosage Rate (mg/kg)

Volume/Amount to Administer = Daily Dosage (mg) ÷ Concentration (mg/mL or mg/g)

Total Treatment Amount = Daily Amount × Treatment Duration (days)

Where:

Dosage Rate = 50 mg/kg for most parasites, 100 mg/kg for Giardia
Concentration = Varies by Panacur form (222 mg/g for granules, 100 mg/mL for suspension, 187.5 mg/g for paste)
Treatment Duration = Varies by parasite type (1-5 days typically)
Pregnant Dogs = Use 50% of standard dosage

Example Calculation

Real-World Scenario:

A veterinarian needs to calculate the Panacur dosage for a 20 kg dog with whipworm infection using Panacur granules.

Given:

Dog Weight = 20 kg
Panacur Form = Granules (222 mg/g)
Treatment Purpose = Whipworms (50 mg/kg)
Treatment Duration = 3 days

Calculation:

Daily Dosage = 20 kg × 50 mg/kg = 1000 mg

Daily Amount = 1000 mg ÷ 222 mg/g = 4.5 g

Total Treatment Amount = 4.5 g × 3 days = 13.5 g

Result: Administer 4.5 g of Panacur granules daily for 3 days, for a total of 13.5 g.

Why This Calculation Matters

Practical Applications

Accurate deworming treatment for intestinal parasites
Prevention of parasite transmission to humans
Treatment of specific parasitic infections
Management of Giardia infections in dogs

Key Benefits

Prevents under-dosing (ineffective treatment)
Avoids over-dosing (potential side effects)
Provides species-specific dosage calculations
Adjusts for special conditions (pregnancy)

Common Mistakes & Tips

Different parasites require different dosages and treatment durations. For example, Giardia requires 100 mg/kg for 5-6 days, while roundworms typically require 50 mg/kg for 3 days. Always match the dosage to the specific parasite being treated.

Panacur comes in different formulations with varying concentrations (granules 22.2%, suspension 10%, paste 18.75%). Using the same volume/amount for different formulations will result in incorrect dosing. Always calculate based on the specific formulation you're using.

Stopping treatment before completing the full course is a common mistake that can lead to treatment failure and potential parasite resistance. For effective treatment, always complete the full recommended duration, even if symptoms appear to resolve earlier.

Frequently Asked Questions

For adult dogs, general deworming is typically recommended 2-4 times per year. However, the frequency depends on your dog's lifestyle, risk factors, and local parasite prevalence. Puppies usually require more frequent deworming, starting at 2 weeks of age and continuing every 2-3 weeks until 6 months of age. Always consult with your veterinarian for a personalized deworming schedule.

Panacur is generally considered safe with few side effects. Some dogs may experience mild gastrointestinal upset such as vomiting or diarrhea, especially at higher doses. Allergic reactions are rare but possible. If you notice any unusual symptoms after administration, contact your veterinarian. Panacur has a wide safety margin and is one of the few dewormers considered safe for pregnant dogs (at reduced dosage).

In many countries, Panacur is available over-the-counter without a prescription. However, it's always recommended to consult with a veterinarian before administering any medication. A proper diagnosis is important to ensure you're treating the right parasite with the appropriate dosage and duration. Your veterinarian can also rule out other potential health issues and provide guidance on preventing future infections.
