Addressing Recent FDA Reports About Heartworm/Flea/Tick Medications

We have heard a lot of concerns in the past few months about some of flea and tick products that fall into the “isoxazoline class” such as Nexgard, Bravecto, Simparica, and Credelio. It all stems from a recent statement from the FDA relating to the potential for neurological effects with the use of these drugs. Its understandably concerning for clients who always want the best for their pets, so we are going to clear up some facts about this class of drugs and their actual relation to these side effects.

McLean Animal Hospital has never experienced any patients with neurological signs since using the drugs Nexgard and Bravecto for the past several years (we have nothing against Simparica or Credelio, but we prefer the ease of use of the former products). Most of the staff members give their dogs Nexgard and Bravecto as well. We must have prescribed thousands of doses at this point, and we’ve never seen a reaction. The Merck representative explained to us that the classification of the neurologic effects with Bravecto use is described as “rare,” which medically means that an adverse event of 1 in 10,000 cases is what that means.

Bravecto seems to be getting the worst of the press right now because they are the only company that needs to update their package to include a caution about potential neurological effects. On the pre-FDA approval testing, Bravecto did not have any reported neurological events, so there was nothing to declare when the drug was first released, which is why they did not have a caution on the packaging until just now. The other drugs did have some neurological events noted in their pre-FDA approval testing, so they launched their products with a caution already on the package. All of these effects were extremely rare, which is why they were all declared safe to come to market.

The general public might not know this, but all drug companies take feedback from clinics very seriously and open case files on any type of reaction to a medication (whether it be vomiting, lethargy etc. or a seizure or tremor). They take names of clients and follow up with us to check up on the health status after any reaction. All of the reactions are logged in a database that can be tracked by the FDA. An interesting thing to note is that the health status of any pet does not preclude them from reporting the reaction. For example, an epileptic dog that is on medication for seizures that have a seizure while taking any isoxazoline drugs would still report that to the company, and they still have to log it in their files, even if the patient had this pre-existing condition.

In conclusion, if anyone has concerns about any of the medications their pet is prescribed, we encourage you to come to our staff with your questions. There are many medication options for protecting against heartworm, flea, and ticks. The risks of heartworm and Lyme disease, in particular, can be very serious for pets, and we feel that the benefit of these drugs far outweighs the very rare side effects that can occur.

COVID-19: Additional measures we are taking

Dear Clients,

Due to the close contact that our work requires, we have taken additional measures to protect you and our team while providing care for your furry family members.

The following changes are effective as of Monday, March 23, 2020:

1. We are currently operating a “closed waiting room” policy to protect our clients and staff. When you arrive, please remain in your vehicle and use your cell phone to call us at 416-752-5114. We will take a history from outside of your vehicle, and bring your pet into the clinic for an examination with the veterinarian. We will then return to your vehicle with your pet to discuss our recommended treatment plan. If you do not have a cell phone please knock our door to let us know you have arrived and then return to your vehicle.

2. We are continuing to accept appointments for urgent or sick pets, as well as time-sensitive puppy/kitten vaccinations. All other services will be scheduled for a later time. We are also no longer taking grooming appointments as of Monday, March 30, until further notice.

3. We are still OPEN with the following hours: Monday to Thursday: 9:00 am - 5:00 pm. Friday: 11:00 am - 7:00 pm.

4. If you are ordering food or medications, please allow 7-10 business days as our suppliers are dealing with increased demand and are trying to fill orders as quickly as possible. We will advise you as soon as your order arrives. Please call us when you arrive to pick up your order, but do not enter the hospital. Our staff will bring your order to your car and take payment over the phone. You can also use our online store and have your food delivered directly to your home. To sign up for the online store, visit our website.

5. For the time being, we are not accepting cash as payment. Credit cards and debit card payments are still available.
