The medicine you give me can do what? (Photo: Getty Images)
Fleas and ticks can reach the nerves of your pet. But apparently, some drugs can also eliminate these parasites.
The US Food and Drug Administration (FDA) has issued a warning that isoxazolines such as Bravecto, Credelio, Nexgard and Simparica could do more than fight flea or tick infestations. These medications can cause seizures, ataxia, muscle tremors or other neurological problems in your pets. Ataxia is a condition in which your animals can not control their muscle movements and may therefore have difficulty walking, balancing or talking. Of course, you will not necessarily know if your pets are having trouble talking. But the FDA's warning means that you should be on the lookout for any difficulties that your pet may have after taking these medications.
It is not a total surprise that these drugs can affect your pet's nervous system. After, these drugs work by playing with the nervous systems of fleas and ticks. Your pet, usually a dog or cat, since alpacas are not common pets, will first consume the drug. The drug then enters the bloodstream of your pet. There, the drug can get into a flea or tick that actively feeds on your pet's blood.
It's where the fun begins with fleas and ticks. As in humans, the nerves of fleas and ticks act as conductive wires of electrical signals that control movement and other functions. These electrical signals normally pass from the nerve to the nerve via neurotransmitters such as gamma-aminobutyric acid (GABA) and glutamate. However, the drug can interfere with the actions of these neurotransmitters, preventing the transmission of these electrical signals. This can then paralyze and kill fleas and ticks, bypassing their nervous systems. Fleas and dead ticks can not spawn or reproduce.

With this mechanism of action, it should not be a total surprise that drugs can also screw up with your pet's nervous system. But before you panic about the drug that paralyzes and kills your pets, keep in mind that drugs are FDA approved for use in pets, assuming your pet is not not a giant chip. Fleas and ticks are luckily much smaller than dogs and cats. They therefore tend to be more sensitive to smaller amounts of medication.
Note that the FDA has not indicated the frequency of these side effects in dogs and cats. The FDA has only issued a warning and asked the manufacturers to include the warning on their labels. The FDA has not advised against using medications for your dogs and cats.

So for you, fleas and ticks hoping that the FDA will remove these drugs from the market, sorry, that will not happen. If you are a human being, this news may not change your flea and tick control methods, but do not use these medications on your pet without the help of a veterinarian. Keep your veterinarian informed of any changes in the behavior of your dog or cat while you are taking these medications. If you are a veterinarian, make sure that pet owners are aware of these potential side effects and discuss flea and tick control options if they are concerned. And if you're a dog or a cat, whew, whew, woof, meow, meow, meow.
