What This Medication Is Used For
Simparica 40 mg chewable tablets are a monthly prescription treatment for medium-sized dogs. This strength is designed for dogs weighing between 10.1 kg and 20 kg and focuses on controlling external parasites.
It is used to treat and prevent flea and tick infestations, helping reduce discomfort and ongoing exposure.
Parasites it helps manage
Fleas
Ticks
Certain mites when recommended by your veterinarian
Common reasons dogs are started on treatment
Frequent scratching or signs of flea irritation
Ticks found after time outdoors
Living in areas where parasites are active throughout the year
Why your veterinarian may recommend it
To control active infestations quickly
To maintain consistent monthly protection
To reduce the risk of skin issues caused by parasites
How It Works
Simparica begins working after your dog eats the chewable tablet. The active ingredient, sarolaner, enters the bloodstream and affects parasites when they feed.
Fleas start dying within a few hours
Ticks are affected shortly after attaching
Protection continues for about a month
The treatment targets the parasite’s nervous system, causing paralysis and death.
It works on parasites present on your dog but does not remove fleas or ticks from your environment. If there is a heavy infestation, you may need additional cleaning or treatment.
How it differs from combination products
This medication focuses only on fleas, ticks, and certain mites. It does not protect against heartworm or intestinal worms.
Use as part of routine prevention
Parasite exposure changes based on season and location. Monthly use helps maintain steady control.
Dosage and Strength Information
Your veterinarian will confirm the correct dosage based on your dog’s weight and health history. Follow their instructions closely.
