Directions for use

  • Hold the pipette upright
  • Tap the narrow part of the pipette to ensure the contents are within the main body of the pipette
  • Break back the snap-off top from the pipette along the scored line
  • Part the coat between the shoulder blades until the skin is visible
  • Place the tip of the pipette on the skin and squeeze gently at one or two spots to empty the contents onto the skin.

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 treated 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 disappear within 24 hours post application. For the optimal control of fleas and ticks the treatment schedule can be based on the local epidemiological situation.

In the absence of safety studies, do not re-apply the product for a minimum of 4 weeks after treatment.
