What Is Toltrazuril?
Toltrazuril (TOLTRAMAX 5% Suspension) is a triazine antiprotozoal drug which is used in veterinary medicine to treat infections with protozoa, especially coccidia.
Coccidiosis is an intestinal disease that is caused by microscopic parasites and can affect puppies as well as young animals and dogs with weak immune systems.
Unlike many types of medications, which only block the growth of the parasite, toltrazuril acts by disrupting the cell development of the parasite by damaging internal structures that are required for the protozoa to reproduce.
This mechanism is helpful for the elimination of the parasite from the digestive system.
Veterinarians sometimes prescribe toltrazuril for dogs off-label for treatment of:
- Coccidiosis (Cystoisospora species).
- Some types of protozoa intestinal infections
- Prolonged infection of puppies by parasites
As dosing is dependent on the animal's weight, a Toltrazuril for Dogs Dosage Chart and Calculator by weight can help to understand how veterinary professionals get to appropriate amounts.
How Much Toltrazuril Can I Give My Dog?
The recommended Toltrazuril (TOLTRAMAX 5% Suspension) dosage is 1 mL per 5 lbs (0.2 mL/lb; 0.44 mL/kg) of body weight, given once daily for 3–5 days, as directed by a veterinarian.

Toltrazuril Dosage Calculator for Dogs By Weight
A Toltrazuril dosage calculator normally follows the steps below:
Step 1: Determine Your Dog's Weight
Weigh the dog in pounds or kilos.
Step 2: Convert Pounds to Kilograms (if required)
1 pound ≈ 0.45 kg.
Step 3: Apply the Veterinary Dosage
Multiply weight in kg * prescribed mg/kg dosage

Step 4: Conversion to Medication Volume
If in liquid form, the total milligrams are divided by the mg per milliliter strength.
Example:
- Dog weight: 10 kg
- Prescribed dose: 15 mg/kg
- Required amount: 150 mg
If the suspension contains 50 mg/ml, then the dose would be 3 ml.
Veterinarians often do this calculation to make sure the correct concentration and dose schedule is done.
What Conditions Does Toltrazuril Treat in Dogs?
Toltrazuril is most commonly related to the treatment of coccidial infections in which the intestinal lining is infected by protozoa.
Common signs of coccidiosis in dogs are of the following:
- Watery or mucus-like diarrhea
- Loss of appetite
- Lethargy
- Weight loss
- Dehydration
- Abdominal discomfort
Puppies are especially vulnerable because their immune systems are not fully developed.
Early treatment helps in prevention of complications and also reduces transmission of the parasite.
How Toltrazuril works Against Coccidia
Toltrazuril works on the multiple stages of the parasite lifecycle.
The medication disrupts:
- Nuclear division (cell achieved in parasite cells)
- Mitochondrial function
- Cell wall development
This multiple stage disruption blocks the growth of the parasite within the intestinal tract. As a result the infection slowly disappears from the body.
How to Give Toltrazuril to Dogs
Toltrazuril is most commonly provided in a liquid type as an oral suspension.
Veterinary instructions can include:
- Giving the medication directly using oral syringe
- Mixing with a small portion of food
- Administering on an empty stomach or with food depending on formulation
Suggestions for safe administration:
- Follow the exact dosage from the veterinary
- Shake liquid suspensions before measuring
- Use a high precision syringe for measurement
- Finish this full course of treatment
Side Effects of Toltrazuril in Dogs
Toltrazuril is generally a drug that appears to be well tolerated in veterinary medicine, but some dogs may experience mild side effects.
Possible reactions include:
- Mild diarrhea
- Reduction of temporary appetite
- Vomiting
- Lethargy
Severe reactions are rare, but pet owners should call a veterinarian if the symptoms worsen or are not improving.
Safety Guidelines for Using Toltrazuril
Responsible use of medications helps to ensure that it is effective and that risks are minimized.

- Only use toltrazuril under veterinary direction.
- Do not guess dosage amounts.
- Double-check the concentration of the medication before measuring.
- Keep track of the dog after it has been treated.
- Keep medication safely away from children and pets.
