Active ingredient

Active ingredient                                                                  mg/ampoule

Lufenuron                                                                             266


Methyl parahydroxybenzoate                                               4.56

Propyl parahydroxybenzoate                                               1.14


The minimum recommended dose rate is 30mg a.i./kg/month. This is achieved by giving cats over 4.5kg the contents of 1 ampoule.

To be fully effective the suspension MUST be administered together with food. Shake the ampoule prior to opening. The suspension should be added to approximately half of the food ration. The rest of the food should be presented when all the dose has been eaten. If several cats are treated, ensure that each cat is fed individually. The product can also be administered by squeezing the suspension directly from the ampoule onto the back of the cat’s tongue after feeding.

To open the ampoule first hold the base tab (which has writing on it) and flick the pack. Then twist off the top portion and squeeze the ampoule several times to administer the suspension.

To prevent flea infestations the product should be administered at monthly intervals for at least six months during the flea season, starting two months before fleas become active. To ensure accurate dosing, cats should be weighed before treatment.

If the cat is already infested with fleas, no viable flea eggs are produced from 24 hours after the first administration. The speed of elimination of the pre-existing infestation is dependent upon the number of flea larvae and pupae in the environment when treatment starts and climatic conditions.

Program does not kill adult fleas. The product works by preventing the development of flea larvae. If cats have a high level of flea infestation at the start of the treatment, it is necessary to apply a product that is recommended for use against adult fleas during the first one or two months, or longer depending on the environmental challenge.

It is essential that all cats and dogs (except unweaned puppies and kittens) living in a household are treated to stop flea reproduction.
