Risk of resistance? YES, low to moderate in:
- fleas, mainly the cat flea, Ctenocephalides felis
- brown dog ticks, Rhipicephalus sanguineus
So far there are only very few confirmed reports on flea resistance to fipronil, 25 years after its introduction for flea control. But there are rumors that the number of product failures is increasing, mainly in the US. Fleas have developed resistance to several other insecticides (e.g. carbamates, organophosphates and pyrethroids) and are certainly capable of becoming resistant to fipronil as well. Experience shows that prolonged and uninterrupted use of any insecticide on fleas (including fripronil) bears the risk of resistance development.
There are no reports on resistance of brown dog ticks to fipronil, but moderate resistance to pyrethroids has been reported in several countries (e.g. Brazil, Panama, Spain, USA).
Alternatives to prevent resistance through product rotation:
- Amitraz (T*): toxic to cats!
- Carbamates (F+T*), e.g. carbaryl, propoxur
- Indoxacarb (F*)
- Insect Development Inhibitors (F*), e.g. lufenuron
- Isoxazolines (F+T*), e.g. afoxolaner, fluralaner, sarolaner
- Macrocyclic lactones (F*), e.g. selamectin
- Neonicotinoids (F*), e.g. dinotefuran, imidacloprid, nitenpyram
- Organophosphates (F+T*), e.g. chlorpyrifos, coumaphos, diazinon, fenthion, etc.
- Pyrethroids (F+T*), e.g. cyphenothrin, cypermethrin, deltamethrin, etofenprox, flumethrin, permethrin, etc. toxic to cats!
- Spinosyns (F*), e.g. spinetoram, spinosad
*F = effective against fleas; T = effective against ticks.
These alternative products may not be available in all countries, or may not be available as spot-ons.
Resistance of fleas and brown dog ticks to carbamates, organophosphates and pyrethroids is not uncommon in several countries, including the USA.

Are the active ingredients of this product ORIGINAL* or GENERICS**?
- Fipronil: GENERIC (introduced in the 1990s)
*Meaning that they are still patent protected and generics are not yet available
**Meaning that they have lost patent protection and may be acquired from manufacturers of generic active ingredients other than the holder of the original patent.
COUNTRIES where this product is marketed (maybe under another TM): UK, Ireland, and other EU countries.
GENERIC BRANDS available? YES; this is a generic brand of MERIALS's FRONTLINE TOP SPOT, the first fipronil spot-on for dogs and cats introduced in the 1990s.

ELIMINALL is ZOETIS' generic fipronil spot-on brand for flea and tick control in dogs and cats.
Administered about every 4 weeks controls established flea infestations and prevents flea populations to develop in the pets environment, but only if all the dogs and cats in the same household are treated. It also kills several tick species (e.g. Dermacentor spp, Ixodes spp, Rhipicephalus sanguineus, Amblyomma americanum, etc,) and chewing lice (Felicola subrostratus, Trichodectes canis).
Fipronil is a broad-spectrum insecticide and acaricide belonging to the phenylpyrazoles introduced in the late 1980s (by RHÔNE MÉRIEUX → MERIAL). It is massively used in pets and agriculture, and also moderately used against household pests and in some countries in livestock too. There are hundreds of generic brands with fipronil.
Nowadays, after fipronil lost patent protection there are dozens of flea spot-ons for dogs and cats with generic fipronil, alone or in several mixtures with other active ingredients. But not all the generic brands are available in all countries.
Topical products (mainly spot-ons and insecticide-impregnated collars) have some advantages over systemic products (mainly tablets for oral administration and injectables):
- Most topical products kill or sterilize the parasites before they bite and suck blood on the pet, whereas systemic products kill or sterilize the parasites only after their blood meal.
- Topical products cannot be vomited.
- Spot-ons and collars are very convenient to administer.
- There is a larger choice of topical products.
But topical products have also some disadvantages:
- Topical products contaminate the pet's hair coat and it is advisable for children and also adults to avoid contact with the pet for several days after treatment.
- Topical products may not control parasites in some parts of the pet's body (e.g. the ears, below the tail, between the legs, etc.), whereas systemic products reach the blood-sucking parasites through the blood wherever they are.
- Efficacy of topical products may be reduced or shortened through exposure to dirt, sun, shampooing, washing, rain, baths, etc., whereas efficacy of systemic products is independent from these factors.
