remain within the main body of the pipette. Snap back the tip. Part the coat on the
back of the animal at the base of the neck in front of the shoulder blades until the
skin is visible. Place the tip of the pipette on the skin and squeeze the pipette several

itching or hair loss have been reported after use. Excessive salivation, reversible

performed to investigate how this affects the efficacy of the product. Emollient
shampoos can be used prior to treatment, but reduce the duration of protection
against fleas to approximately 5 weeks when used weekly after application of the
product. Weekly bathing with a 2% chlorhexidine medicated shampoo did not affect
efficacy against fleas during a 6 week long study.
There may be an attachment of a few ticks. For this reason a transmission of
infectious diseases cannot be completely excluded if conditions are unfavourable.
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.

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
