Tick treatment and prevention

Pyriprole kills ticks within 48 hours post-exposure. One application is effective against ticks for 4 weeks.

Method of administration

For application to the skin only.

Remove one pipette from the package. Hold it 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 in order to prevent run-off.

Contra-indications, warnings, etc

Do not use in dogs less than 8 weeks of age or with a body weight of less than 2 kg.

Do not use in case of known hypersensitivity to phenylpyrazole class compounds or any of the excipients.

Do not use on sick (e.g. systemic diseases, fever) or convalescent animals.

This veterinary medicinal product is specifically developed for dogs. Do not use in cats, as this could lead to overdosing.

Do not use in rabbits.

On very rare occasions the following have been reported:

- Application site and skin reactions: pruritus, hair change, dermatitis, erythema, alopecia, fur discolouration and

greasy appearance of hair.

- Neurological reactions: ataxia and convulsions.

- Systemic reactions: lethargy.

- Digestive tract reactions: emesis and diarrhoea.

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

consult your veterinarian.

A brief period of hyper salivation 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.

As a precautionary measure, people should avoid contact with the treated area of the animal and children should not be allowed to play with treated animals until the application site is dry. It is therefore recommended to treat animals in the evening. 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 the veterinary medicinal product.

Avoid skin contact with the pipette content. Wash hands or other exposed body parts after use with soap and water. If accidental eye exposure occurs, the eyes should be rinsed carefully with water. If eye irritation persists seek medical advice and show the package leaflet or the label to your doctor.

Do not smoke, eat or drink during application.

Apply only to the skin surface and on intact skin. This veterinary medicinal product is external topical applicationas a spot-on treatment only. Do not administer orally or via any other route. The dog should be accurately weighed before the treatment. Care should be taken to avoid contact of the veterinary medicinal product with the eyes of the animal.

It is important to apply the dose to an area where the dog cannot lick it off and to make sure that animals do not lick each other following treatment.

Following treatment, ticks will detach from the host within 24 to 48 hours after infestation; however, single ticks

might remain on the animal. For this reason, a transmission of infectious diseases by ticks cannot be completely

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

In cases of heavy infestation prior to treatment, the dog’s surrounding should be vacuumed and treated with a suitable insecticide.

Dogs should not be bathed or shampooed from 48 hours before treatment. Immersion of the animal in water or shampooing within 24 hours after treatment may reduce the efficacy of the veterinary medicinal product. However, weekly immersion in water did not affect efficacy against fleas and ticks. The safety of the veterinary medicinal product has not been established in pregnant or lactating bitches, nor in breeding animals, although in laboratory animal studies no indications of relevant effects on reproduction or foetal development were observed. Use only accordingly to the benefit/risk assessment by the responsible veterinarian. Any unused veterinary medicinal product or waste materials derived from such veterinary medicinal products should be disposed of in accordance with local requirements. Prac-tic should not enter watercourses as this may be dangerous for fish and other aquatic organisms.

Store the pipettes in the original container in order to protect from light.

Do not store above 25°C.

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

Do not remove the pipette from the packaging until ready to use.

Further information

Interaction with other medicinal products and other forms of interaction: None Known, however owners are advised to consult a veterinary surgeon if they intend to use the product on dogs given other products /medication.

The veterinary medicinal product is an insecticidal and acaricidal solution for spot-on use, containing Pyriprole as active substance.

Pyriprole is an insecticide and acaricide belonging to the phenylpyrazole class. It acts by interacting with ligandgated chloride channels, in particular those gated by the neurotransmitter gamma-aminobutyric acid (GABA), thereby blocking pre- and post-synaptic transfer of chloride ions across cell membranes. This results in uncontrolled activity of the central nervous system and death of fleas and ticks.

Parasites are killed through contact rather than by systemic exposure. Pyriprole kills fleas within 24 hours and ticks (Ixodes ricinus, Rhipicephalus sanguineus, Dermacentor reticulatus, Ixodes scapularis, Dermacentor variabilis, Amblyomma americanum) within 48 hours post-exposure.

Adult fleas are killed before they lay eggs for a minimum of 4 weeks after treatment. Since Prac-tic completely eliminates egg production, it breaks the flea life cycle.

Excipients: 0.1% Butylhydroxytoluene (E321), among others.

Bathing my dog

Jamie Macdonald

Will it be ok for me to wash my dog regularly after applying prac tic also how long after flea treatment has been applied can i use a worming tablet thanks.....

  • Website Content Developer

Hi Jamie,

Dogs should not be bathed or shampooed from 48 hours before treatment. Immersion of the animal in water or shampooing within 24 hours after treatment may reduce the efficacy of the veterinary medicinal product. However, weekly immersion in water did not affect efficacy against fleas and ticks.

I hope this helps.

Prac-Tic after Frontline

Derrick Ward

  • VioVet Customer Since: May 2016
  • From: South Glamorgan, United Kingdom

How soon after using Frontline (which failed) can I use Prac-Tic?

  • Non-Executive Director

The active ingredients are completely different, so there should be no adverse interaction using these products in quick succession. However it is good general advice to allow 7 days between any types of spot-on medication to reduce the chances of skin irritation, so I would suggest that length of time.

On the topic of Frontline not working, I would say that it is not a terribly potent product and I feel it tends to kill off a large percentage of the fleas around, but not every single one. If it is used before fleas are seen as a preventative and applied every month, it is actually extremely effective. No fleas are normally ever seen when it is used like this. However if it is applied after fleas are seen, it often takes a few months to eradicate the problem if no other porduct is used. It will get there in time, but these days there are other options as you are aware. Some other spot-ons do appear to be more effective in this circumstance, but I do not think that this is down to fleas developing "resistance" to Frontline. It has always worked like this, but at one time it was far and away the best product out there. Now there is much more choice.
