What is a Generic Drug?

A generic drug is a copy of the brand-name drug with the same dosage, safety, strength, quality, consumption method, performance, and intended use. Before generics become available on the market, the generic company must prove it has the same active ingredients as the brand-name drug and works in the same way and in the same amount of time in the body.

The only differences between generics and their brand-name counterparts is that generics are less expensive and may look slightly different (eg. different shape or color), as trademarks laws prevent a generic from looking exactly like the brand-name drug.

Generics are less expensive because generic manufacturers don't have to invest large sums of money to develop a drug. When the brand-name patent expires, generic companies can manufacture a copy of the brand-name and sell it at a substantial discount.


Simparica is a combination flea and tick killer medication for dogs, and it is particularly recommended for tick control with the fact it is proven to kill 5 different types of ticks – Gulf Coast tick, Brown dog tick, Deer tick / Black-legged tick, American dog tick, and Lone Star tick. It’s administered a flavored chewable tablet for flea and tick prevention, and one chew provides up to 35 days of protection from fleas and ticks. Simparica starts to work quickly, killing fleas within 3 hours of administering and ticks within 8 hours.


Give your dog one Simparica flea and tick chew once a month, either directly or mixed into wet dog food if your pet won’t eat them as is. Refer to the dosage guidelines provided with your prescription to determine what quantity of chews to give your dog based on their body weight. Give your dog the next chewable at approximately the same time next month for best protection against fleas and ticks. 


The ingredient in Simparica flea and tick chews is Sarolaner 5mg. 


Simparica is for use only in dogs 6 months of age and older. Administering Simparica may result in neurologic symptoms like tremors, unsteadiness and/or seizures in dogs with or without a history of neurologic disorders, although this is very uncommon. Simparica has not been evaluated in pregnant, breeding or lactating dogs.


There are no known interaction risks between Simparica flea and tick medication and other Rx medications 

Side Effects

Side effects from the use of Simparica are also uncommon, but may include vomiting, diarrhea, or pruritus (excessive skin itching). If any of these symptoms are observed or your dog is visibly unwell after beginning the course of medications you should discontinue use immediately and speak to your veterinarian regarding flea and tick control alternatives.
