EFFECTVET™ ULTRA for dogs (spot-on solution)

Oily yellowish to reddish-brown liquid with a characteristic odour.

1 ml of the product contains the active substance:

- fenthion - 100,0 mg

Excipients: 1,2-propylene glycol, flavouring agent, glycerol, benzyl alcohol, isopropyl alcohol.

ATCvet QP53A, ectoparasiticides for topical use with insecticides (QP53AF07 - fenthion).

Fenthion is an insecticide belonging to the organothiophosphate group of compounds. Its mechanism of action involves the inhibition of acetylcholinesterase at the synapses of the parasite's central nervous system (CNS), leading to its death. Fenthion penetrates the blood-brain barrier of warm-blooded animals poorly; however, when applied externally, it is absorbed through the skin and enters the bloodstream. Blood-sucking parasites die as a result of fenthion entering their organisms via the blood of treated animals.

For the treatment and prevention of flea infestations (siphonapterosis) in dogs caused by wingless insect ectoparasites: Ctenocephalides canis (dog flea), Ctenocephalides felis (cat flea), Pulex irritans (human flea).

Before use, cut the tip of the pipette with scissors.

- dogs weighing 3 to 10 kg - 1 pipette of 1,0 ml;

- dogs weighing 10 to 20 kg - 2 pipettes of 1,0 ml or 1 pipette of 2,0 ml;

- dogs weighing 20 to 30 kg - 3 pipettes of 1,0 ml;

- dogs weighing 30 to 50 kg - 2 pipettes of 2,0 ml;

- dogs weighing over 50 kg - 3 pipettes of 2,0 ml.

A single treatment protects animals against ectoparasite infestation for 3–6 weeks. Repeat treatments should be carried out every 3–4 weeks.

Contraindications

Hypersensitivity to fenthion.

Do not use in puppies under 6 months of age or weighing less than 3 kg!

Do not use in animals simultaneously or within several days before or after treatment with, or exposure to, products that inhibit cholinesterase, such as carbamates, levamisole, morantel, or pyrantel.

Fenthion must not be used in animals suffering from diarrhoea, chronic constipation, colic, convulsions, respiratory disorders, or renal and/or cardiac impairment.

Do not use in debilitated, ill, or emaciated animals.

Do not use in pregnant animals or lactating females.

To be used only under veterinary supervision.

In sensitive animals following treatment, or in animals that have licked the product immediately after application, signs of nervous disorders may occur (hypersalivation, vomiting, restlessness, bloating, generalised tremors, dilated pupils, respiratory distress, ataxia). These signs resolve within a few minutes without additional treatment. In the event of allergic complications (skin rash, pruritus, and oedema), desensitising therapy is recommended. Antidote: atropine sulphate.

In cases of extensive skin damage, topical treatment with fenthion may result in excessive percutaneous absorption with development of parasympathetic symptoms.

Depolarising muscle relaxants must not be administered within 10 days following administration of organophosphate compounds, as they potentiate adverse effects.

Fenthion must not be used concomitantly with neuroleptic medicinal products.

Observe the basic hygiene and safety rules applicable when working with veterinary medicinal products.

Animal treatment should be carried out in the open air, using rubber gloves.

The product must be applied to areas inaccessible for licking; prevent other animals from licking the product.

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

After working with the product, wash hands with warm water and soap; wash and dry gloves. If the product accidentally contacts skin or mucous membranes, rinse immediately with running water.

Avoid contact of the product with the animal's eyes. Do not apply to damaged skin or wounds.

After treatment, animals must not be stroked by hand or allowed near children until the coat is completely dry. Treated animals must also not sleep together with their owners, especially with children.

Animal care items and areas where animals are kept (bedding, mats, furniture) should be regularly cleaned and treated with appropriate insecticides.
