Containing the renowned active ingredient Fipronil, known for its potency and safety, Flevox provides powerful and durable flea and tick protection. Flevox comes in an easy-to-administer, simple pipette. Applied to the skin on the scruff of the neck in dogs and cats, Flevox is regarded as having an ideal balance between safety and effectiveness for the lasting control of feline and canine fleas and ticks. As with all flea treatments, Flevox Spot-on is ideally used regularly to prevent infestations. Once fleas are being seen, it can be too late for proper control, and difficult to clear the reservoir population from the environment. To provide the best control against fleas, VioVet recommends using Flevox on pets and also the household insecticide Indorex on soft furnishings, carpets and floors.

It is important to make sure that the product is applied to an area where the animal cannot lick it off, and to make sure that animals do not lick each other following treatment.
Care should be taken to avoid excessive wetting of the hair with the product since this will cause a sticky appearance of hairs at the treatment spot. However, should this occur, it will generally disappear within 24 hours post application but can persist for up to 2 weeks.
Do not use on puppies less than 8 weeks old and/or weighing less than 2 kg in the absence of available data.
Do not use on sick (systemic diseases, fever…) or convalescent animals.
Do not use in rabbits, as adverse drug reactions and even death could occur.
Do not use in case of hypersensitivity to fipronil or to any of the excipients.
Do not administer orally.
This product has been developed specifically for dogs. Do not use on cats as this could lead to overdosing.
Special warnings for each target species
Fleas from pets often infest the animal’s basket, bedding and regular resting areas such as carpets and soft furnishings which should be treated, in case of massive infestation and at the beginning of the control measures, with a suitable insecticide and vacuumed regularly.
Ticks already on the animal prior to treatment may not be killed within the first 48 hours after application of the product, but they may be killed within a week. Removal of ticks already on the animal at the time of application is recommended. The product does not prevent ticks from attaching to the animal. If the animal has been treated prior to exposure to the ticks, most ticks will be killed within 48 hours of infestation. This will usually be prior to engorgement, minimising but not excluding the risk of transmission of diseases. Once dead, ticks will often drop off the animal, but any remaining ticks may be removed with a gentle pull.
No data on the effect of bathing/shampooing on the efficacy of the product are available. Therefore, bathing/immersion in water within 2 days of application and more frequent bathing than once a week should be avoided.
For optimum control of flea problems in a multi-pet household, all dogs and cats in the household should be treated with a suitable insecticide.
When used as part of a strategy for the treatment of Flea Allergy Dermatitis, monthly applications to the allergic patient and to other cats and dogs in the household are recommended.
Special precautions for use in animals
Animals should be weighed accurately prior to treatment.
Avoid contact with the animal’s eyes. In case of accidental eye contact, rinse immediately with plenty of water.
Do not apply the product on wounds or damaged skin.
Specific studies investigating the safety of the product following repeated administration have not
been conducted due to the known safety profile of the active substance and excipients.
Fipronil may adversely affect aquatic organisms. Dogs should not be allowed to swim in watercourses for 2 days after application.
Adverse reactions (frequency and seriousness)
If licking occurs, a brief period of hypersalivation may be observed due mainly to the nature of the carrier.
Among the extremely rare suspected adverse reactions, transient cutaneous reactions at the application site (skin discoloration, local alopecia, pruritus, erythema) and general pruritus or alopecia could occur after use. Exceptionally, hypersalivation, reversible neurological signs (hyperaesthesia, depression, nervous signs), vomiting or respiratory signs could be observed after use.
Use during pregnancy or lactation
Laboratory studies using fipronil have not shown any teratogenic or embryotoxic effect. No study was conducted with this product on pregnant and lactating dogs. Use only according to the benefit/risk assessment by the responsible veterinarian.
Symptoms, emergency procedures, antidotes), if necessary
No adverse effects were observed in target animal safety studies in dogs and puppies aged 8 weeks and older and weighing about 2 kg treated once up to five times the recommended dose. The risk of experiencing adverse effects may however increase with overdosing, so animals should always be treated with the correct pipette size according to bodyweight.
This product can cause mucous membrane and eye irritation. Therefore, contact of the product with mouth and eyes should be avoided.
In case of accidental eye contact, rinse immediately with plenty of water. If the irritation persists, seek medical advice and show the container or the package leaflet to the physician.
Avoid contents coming into contact with the fingers. If this occurs, wash hands with soap and water. Wash hands after use.
Do not smoke, drink or eat during application.
Operators with a known hypersensitivity to fipronil or any excipient should avoid contact with the product.
Treated animals should not be handled until the application site is dry, and children should not be allowed to play with treated animals until the application site is dry. It is therefore recommended that animals are not treated during the day, but should be treated during the early evening, and that recently treated animals should not be allowed to sleep with owners, especially children.

Below are some recent questions we've received regarding Flevox Spot-On for Dogs & Cats, including answers from our team.
I applied a cheap dog flea treatment after finding a flea on my dog on Monday. He has had this before but this time it doesnt seem to have worked.
I have bought Vetzyme insecticidal dog shampoo which I intend to use today followed by Flexox but want to know how long I should wait from shampooing to using the Flexox as I dont want to make my dog ill? Also after using frontline on my cat she seems to have developed scabs at the base of her hair although her coat looks ok and a nervous thing and wont come in the house .Do you think this may be a side effect of the front line?
Now that you have spotted a flea, it is very likely that there are high numbers of other fleas, developing from eggs, larvae and pupae in nooks and crannies around your house. A small proportion of these will probably jump onto your dog and cat every day. If suitable treatment has been applied, they will die off over a day or two, but they will still be able to bite you pets in that time.
It sounds as if your cat has "milliary dermatitis" which is often called "flea allergy". The scabs you have noticed are probably her reactions to flea saliva injected under the skin when a flea bites. Hence this is a reaction to fleas, not to the treatment, which you should continue with.
You should allow 48 hours between shampoo and spot-on applications. You would be well advised to treat your house for fleas, with a product like Indorex. You will be able to get the fleas under control, but some will be around for a while and it is very difficult to get rid of all of them in less than a month or two.
