What is Advocate and what is it used for?
Advocate is a medicine used on cats, ferrets and dogs suffering from, or at risk from, mixed parasitic infections (caused by several different types of parasites):
•for the treatment and prevention of flea infestations in cats, ferrets and dogs
•as part of treatment strategies for flea allergy dermatitis (an allergic reaction to flea bites) in cats and dogs
•for the treatment of ear mite infestations in cats and dogs
•for the treatment of notoedric mange in cats
•for the treatment of biting lice infestations in dogs
•for the treatment of skin diseases in dogs caused by parasitic mites (sarcoptic mange and demodicosis)
•for the prevention of heartworm disease in cats, ferrets and dogs
•for the prevention and treatment of dirofilariosis (infection with the heartworms Dirofilaria immitis and Dirofilaria repens) in dogs.
•for the prevention and treatment of lungworm in dogs
•for the prevention of spirocercosis (a worm infection affecting the gullet) in dogs

It contains two active substances, imidacloprid and moxidectin.
How is Advocate used?
Advocate is available as a
The dose and frequency of application depends on why Advocate is being used and whether it is used in cats, ferrets or dogs; the package leaflet includes detailed information on dosage and duration of treatment.
How does Advocate work?
Imidacloprid interferes with certain specific receptors (nicotinergic acetylcholine receptors) in the nervous systems of lice and fleas, which results in their subsequent paralysis and death.
Moxidectin causes paralysis and death of nematodes and heartworms by interfering with the way signals are passed between nerve cells (neurotransmission) in the parasites’ nervous system.
How has Advocate been studied?
The effectiveness of the products against the specified parasites was investigated in laboratory studies. Subsequently the efficacy was confirmed in several field studies in cats and dogs, which were conducted in several different European geographical locations. Cats and dogs from various breeds, age groups and weights were treated. Field studies involving heartworm in dogs were conducted both in the USA and Europe. The effectiveness of the product was measured by looking at the number of live parasites at various times after treatment. Efficacy studies were also performed in ferrets.
What benefits of Advocate have been shown during the studies?
The results of the laboratory and field trials in cats, ferrets and dogs showed that Advocate is effective, when used as detailed in the package leaflet (see “What is Advocate used for?” above, or for more details see the package leaflet).
What are the risks associated with Advocate?
In both cats and dogs the most common side effects are local reactions at the site of application, such as temporary itchiness, and on rare occasions, greasy fur and redness of the skin. Vomiting has also occurred rarely. These signs disappear without further treatment. If a cat or dog licks the application area, it might salivate for a short period and might show signs such as a lack of muscular co- ordination, shaking, abnormal breathing and/or vomiting.
Although no side effects have been confirmed in ferrets, similar side effects could occur rarely.
Dogs and cats weighing less than 1 kg and ferrets weighing less than 0.8 kg should only be treated after special consideration by the veterinarian.
Advocate should not be used in kittens under 9 weeks of age or in puppies under 7 weeks of age.
Advocate should not be used in dogs classified as Class 4 for heartworm disease.
Advocate comes in different strengths and different pipette sizes depending on whether it is for use on cats, ferrets or dogs. It is very important that the cat products should only be used for cats, and the dog products for dogs. Only the product called “Advocate
