EPAR summary for the public



This document is a summary of the European Public Assessment Report. Its purpose is to explain how

the assessment done by the Committee for Medicinal Products for Veterinary Use (CVMP) on the basis

of the documentation provided, led to the recommendations on the conditions of use.

This document cannot replace a face-to-face discussion with your veterinarian. If you need more

information about your animal’s medical condition or treatment, contact your veterinarian. If you want

more information on the basis of the CVMP recommendations, read the scientific discussion (also part

of the EPAR).

What is Prac-tic?

Prac-tic is a spot-on solution that contains pyriprole as active substance.

It is given to dogs with pre-filled spot-on pipettes, i.e. small plastic containers which are already filled

with the correct amount of Prac-tic needed to treat one dog (Pract-tic is available in 4 different sizes

for different dog sizes). For large dogs a combination of pipettes might be needed to achieve the

correct dose. The content of the pipette is squeezed onto the skin after parting the fur in one up to

three spots between the shoulder blades and down the backline of the dog.

What is Prac-tic used for?

Prac-tic is an “ectoparasiticide”, which means that it will kill parasites that live on the skin or in the fur

of animals, such as fleas and ticks.

Prac-tic is used to treat and to prevent tick and flea infestations in dogs. Once applied, it remains

active for at least 4 weeks.

How does Prac-tic work?

Pyriprole, interacts with a receptor involved in transmitting neural impulses (GABA receptor). This

interferes with the nervous system of fleas or ticks and leads to the death of these parasites. Adult



Page 2/3

fleas are killed before they lay eggs; since Prac-tic completely eliminates egg production, it breaks the

flea life cycle.

How has Prac-tic been studied?

Data were provided on the pharmaceutical quality, the tolerance of the product in dogs and the safety

in humans (people in contact with the product) and the environment.

The effectiveness of pyriprole against flea and tick infestations in dogs was investigated in laboratory

studies and in field trials.

Two field studies were conducted in dogs at veterinary practices in several European countries and

different geographic regions. Dogs from various breeds, age groups and weight that were infested with

fleas or ticks were either treated with Prac-tic or with other products authorised in the EU for this

indication. The effectiveness was measured looking at the number of live ticks or number of fleas at

various times up to 3 months after application.

What benefit has Prac-tic shown during the studies?

The results of the field trials showed that Prac-tic is effective in the treatment and prevention of flea

and tick infestations in dogs. The medicine killed fleas within 24 hours and ticks within 48 hours after

treatment and its effectiveness lasted for at least 4 weeks.

What is the risk associated with Prac-tic?

The most common side effects in dogs are local reactions at the place where the product has been

applied: change in the fur colour, hair loss and itchiness, as well as change in appearance of the fur

(greasy appearance and clumpiness). If a dog licks the application area, the dog might salivate a lot

for a short period.

Prac-tic should not be used in dogs less than 8 weeks old or less than 2 kg bodyweight since it has not

sufficiently been studied in these animals. As other products of this group, Prac-tic should not be used

in sick animals or dogs that have just recovered from illness. This product is specifically developed for

dogs and should not be used in any other animal species.

Prac-tic should not be allowed to enter surface water, as it may be harmful for aquatic organisms.

What are the precautions for the person who gives the medicine or comes

into contact with the animal?

As a precautionary measure, direct contact with the treated dog should be avoided and children should

not be allowed to play with a treated animal until the application site is dry. Recently treated animals

should not be allowed to sleep in the same bed as their owners, especially children.

People with known hypersensitivity to the phenylpyrazole class compounds or any of the excipients

should avoid contact with Prac-tic.

Skin contact with the pipette content should be avoided. Skin should be washed and eyes should be

rinsed with water, if accidental exposure occurred. When administering Prac-tic, the user should not

smoke, eat or drink.

Why has Prac-tic been approved?

The Committee for Medicinal Products for Veterinary Use (CVMP) concluded that the benefits of Prac-tic

exceed the risks for the approved indications and recommended that Prac-tic be given a marketing

authorisation. The benefit-risk balance may be found in the scientific discussion module of this EPAR.

Other information about Prac-tic:

The European Commission granted a marketing authorisation valid throughout the European Union, for

Prac-tic to on 18 December 2006. Information on the prescription status of this product may be found

on the label/outer package.

This summary was last updated in December 2012.

On very rare occasions the following have been reported:

- application site and skin reactions :pruritus (itchy skin), hair change, dermatitis (inflammation of the

skin), erythema (redness of skin), alopecia (loss of hair), fur discoloration and greasy appearance of


- neurological reactions: ataxia (lack of coordination) and convulsions.

- systemic reactions: lethargy (drowsiness).

- digestive tract reactions: emesis (vomiting) and diarrhoea.

Those signs are usually transient and disappear within 24 hours of the application; if they take longer

to disappear consult your veterinarian.

A brief period of hypersalivation (drooling) may occur if the animal licks the application site

immediately after treatment. This is not a sign of intoxication and disappears within minutes without

treatment. Correct application will minimise licking of the application site.

The frequency of adverse reactions is defined using the following convention:

- very common (more than 1 in 10 animals treated displaying adverse reaction(s))

- common (more than 1 but less than 10 animals in 100 animals treated)

- uncommon (more than 1 but less than 10 animals in 1,000 animals treated)

- rare (more than 1 but less than 10 animals in 10,000 animals treated)

- very rare (less than 1 animal in 10,000 animals treated, including isolated reports).

If you notice any side effects, even those not already listed in this package leaflet or you think that the

medicine has not worked, please inform your veterinary surgeon.

Remove one pipette from the package. Hold the pipette in an upright position. Tap the narrow part of

the pipette to ensure the contents are in the main body of the pipette. Snap-off the top of the pipette

along the scored line.

Part the coat on the back of the animal between the shoulder blades until the skin is visible. Place the

tip of the pipette on the skin and squeeze it gently several times at one or two spots to empty the

contents onto the skin. Ensure the product is deposited on the skin. Apply the 5 ml pipette to 2-3 spots

down the backline of large dogs so as to prevent run-off.

The dogs should be accurately weighed before the treatment to ensure the correct pipette size is used.



Not applicable.



Keep out of the sight and reach of children.

Do not use after the expiry date stated on the pipette after “EXP”.

Keep the pipettes in the original blister package until ready to use, in order to protect from light.

People with known allergies to the phenylpyrazole class of compounds or any of the excipients should

avoid contact with the product.

Avoid the contents coming into contact with your fingers. Wash your hands after use and wash off any

product in contact with your skin with soap and water. If the product accidentally gets in your eyes,

rinse them carefully with water. If eye irritation persists seek medical advice and show the package

leaflet or the label to the doctor

If you come into contact with the product, it may happen that your skin and mucosa become numb and

irritated but these conditions usually disappear spontaneously.

If you or anybody else accidentally swallows this product, seek medical advice immediately and show

this leaflet or the label to your doctor.

Do not smoke, eat or drink while handling the product.

As a precautionary measure, direct contact with the treated dogs should be avoided and children

should not be allowed to play with treated dogs until the application site is dry. It is therefore

recommended to treat dogs in the evening. Recently treated dogs should not be allowed to sleep in the

same bed as their owners, especially children.

This veterinary medicinal product is for the treatment of ticks and adult fleas. All dogs in a household

should be treated at the same time.

Special precautions for use in animals

Following treatment, ticks will drop off from the dog within 24 to 48 hours after coming into contact

with the animal; however, single ticks might remain on the animal. For this reason, a transmission of

infectious diseases by ticks cannot be completely excluded.

In cases of heavy infestation prior to treatment, the dog’s surrounding should be vacuumed and treated

with a suitable insecticide.

Apply only to the skin surface and on intact skin.

The product is for skin application on dogs only; do not put in your dog’s mouth. Take care to avoid

the veterinary medicinal product coming into contact with your dog’s eyes.

Consult a veterinary surgeon if it is intended to use the product on dogs with other products or


Do not give the product by mouth as this can lead to an overdose, or any other route.

The safety of the product has not been established in breeding dogs, including pregnant or lactating

dogs. If you suspect your dog may be pregnant or if your bitch is nursing puppies or if you want to

treat a breeding dog, contact your veterinarian for advice before use.

Overdose (symptoms, emergency, procedures, antidotes):

Mild neurological signs such as slight incoordination and unsteadiness were observed in some animals

treated once a month. Those signs disappeared within 3 hours following administration.

In one out of 8 dogs the following transient adverse effects were observed: tremors (shaking), ataxia

(lack of coordination), panting and convulsions. These signs disappeared within 18 hours following


Following an overdose on a single occasion the following adverse effects were seen: vomiting,

anorexia (loss of appetite), reduced body weight, muscle tremors, seizures, unsteadiness, laboured

breathing. All signs resolved within 48 hours, with the exception of the loss of appetite.

An overdose of the product may cause a sticky and tangled appearance of hair at the treatment spot for

up to 24 hours.

In case of an overdose contact your veterinary surgeon

Apply the dose to an area where your dog cannot lick it off and do not allow your dog or other

animals lick each other following treatment.

Dogs should not be bathed or shampooed from 48 hours before treatment. Immersion of your dog in

water or shampooing within 24 hours after treatment may reduce the efficacy of the product. If you

want to wash your dog, leave at least one day between treatment and shampooing.

When administering the product, try to avoid wetting the fur as this will lead to a sticky and tangled

appearance. However, should this happen it will disappear within 24 hours.

The solvent in Prac-tic may stain certain materials including leather, fabrics, plastics and finished

surfaces. Allow the application site to dry before permitting contact with such materials.
