Johnson's 4Fleas 57 mg Tablets for Dogs

The minimum effective recommended dose is 1 mg/kg, with the following
recommendations:
One Johnson’s 4Fleas 57 mg tablet should be given to dogs weighing 11.1 kg to 57.0
kg and two tablets for dogs weighing over 57 kg when a flea infestation is detected.
The frequency of treatment depends on the degree of infestation. In the case of a
severe flea infestation, it may be necessary to treat the animals every day or every
other day, until the flea infestation is controlled. Treatment may be resumed if fleas
reappear. No more than one treatment should be given per day.
Tablets should be given orally, with or without food. In order to improve palatability,
tablets can be disguised in a small quantity of food immediately prior to
administration.
Johnson’s 4Fleas tablets do not have persistent activity. To prevent re-infestation, a
suitable treatment to control immature stages of the flea life cycle is recommended.
The veterinary surgeon should establish an appropriate treatment regime.
