I have read that Simparica may cause side effects including muscle tremors, diarrhea, lethargy, anorexia, otitis externa, hyperactivity, neurological side effects, seizures, convulsions, anxiety and skin irritation.
Side Effects & Warnings
Simparica is for use only in dogs, 6 months of age and older. Simparica may cause abnormal neurologic signs such as tremors, unsteadiness, and/or seizures. Simparica has not been evaluated in dogs that are pregnant, breeding or lactating.
Simparica may cause neurologic signs such as tremors, unsteadiness and/or seizures in dogs with or without a history of neurologic disorders.
Side effects
Simparica for dogs is a drug from the isoxazoline class. This class has been linked to neurological signs such as tremors, unsteadiness, and seizures in dogs. However, the FDA considers drugs in the isoxazoline class to be safe and effective for dogs.
Monthly Simparica protects dogs from ticks and fleas for 35 days. Have you ever been a few days late giving your dog monthly tick and flea protection?
If you give your dog or cat the flea and tick preventatives Bravecto, Nexgard, Simparica, or Credelio, the FDA wants you to be aware that these medications may cause neurological issues like stumbling, seizures, and twitching in your pet.
The police dog in question who was given Simparica Trio eventually recovered. It is important to help the animal detox, giving a twice-daily dose of 250-500 mg milk thistle for three to four weeks, plus a few drops of fish oil and a teaspoon of coconut oil daily.
As you can see, both Nexgard and Simparica are extremely good and effective flea and tick treatment and they do not have a major difference between them. But that being said, Simparica does kill an additional tick specie and is relatively faster in eliminating fleas and ticks.
For flea or tick infestations, one treatment with Simparica Trio is effective for up to 5 weeks. Further flea or tick treatment should be continued using a different veterinary medicine with a narrower range of action.
Results: Simparica Trio was generally well tolerated. Emesis occurred at low frequency in all groups including control. Abnormal stool occurred occasionally in the 1× and 3× groups throughout the 3-month study.
The cumulative deaths reported to April 2021 ranged from a high of 2,627 (24%) for fluralaner (Bravecto®) to 726 (2.8%) for afoxolaner (NexGard®) and 412 (12.7%) for sarolaner (Simparica®).
Simparica. The top three adverse events that have been observed in pets taking Simparica are vomiting, diarrhea and lethargy and the occurrence of these side effects are 1 in 10,000.
SIMPARICA TRIO contains sarolaner, a member of the isoxazoline class, which has been associated with neurologic adverse reactions including tremors, ataxia, and seizures in dogs with or without a history of neurologic disorders.
Simparica may cause neurologic signs such as tremors, unsteadiness and/or seizures in dogs with or without a history of neurologic disorders. Simparica has not been evaluated in pregnant, breeding or lactating dogs. The most common adverse reactions in clinical trials were vomiting and diarrhea.
Both products are safe for dogs when following directions and have been approved by the FDA to treat and prevent flea and tick infestations. However, unlike Bravecto, Simparica has yet to be approved for use in breeding, pregnant, or lactating dogs.
That same information showed 720 reported seizures for Bravecto in four years and 557 for Simparica in three years. For Credelio, six seizures were reported in the first six months after its approval.
There are no known contraindications for the use of SIMPARICA TRIO. Not for use in humans. Keep this and all drugs out of reach of children. Keep SIMPARICA TRIO in a secure location out of reach of dogs, cats and other animals to prevent accidental ingestion or overdose.
Dogs that have ataxia may fall, have difficulty walking, walk in circles, or tilt their heads. You may notice that your dog's eyes flutter side to side or up and down. Vestibular ataxia can make your dog feel dizzy and nauseated and may cause vomiting.
If chemical products are necessary for additional flea or tick control, NRDC recommends s-methoprene or pyriproxyfen, which are less toxic ingredients—but read the labels carefully because some products use them with other, more harmful pesticides.
Simparica may cause neurologic signs such as tremors, unsteadiness and/or seizures in dogs with or without a history of neurologic disorders. Simparica has not been evaluated in pregnant, breeding or lactating dogs. The most common adverse reactions in clinical trials were vomiting and diarrhea.
Both of these brands are recommended by vets and are easy, convenient, and effective. Simparica protects against more varieties of ticks than Bravecto does and also offers a variation that protects against worms. Bravecto is effective for three times longer (12 weeks), while Simparica must be reapplied monthly.
The tablets should not be divided.
The primary route of sarolaner elimination from dogs is biliary excretion with elimination via the feces.
This is nothing to be concerned about just really good to be aware of as it may look like your dog is scratching more after you gave the Simparica than before. This will be over very quickly as Simparica kills them all fast. Fleas are killed so quickly with Simparica that they are not able to lay eggs.
