Dear Daisy Dog
I give my dog Interceptor every month to prevent heartworms and intestinal parasites. On a recent shopping trip, I discovered a dewormer called piperazine that was less expensive. Is it just as good as Interceptor?
No, it’s an entirely different medication, one that kills only roundworms.
Interceptor has a much broader spectrum of anti-parasite activity, preventing infection by heartworms, which invade the heart and lungs, as well as three intestinal parasites: roundworms, hookworms and whipworms.
Hookworms and roundworms can infect humans, too, so Interceptor is superior because it hits both.
Piperazine side effects include vomiting, diarrhea, muscle tremors and loss of coordination. It shouldn’t be used in pets with liver or kidney disease or in animals with seizures or decreased gastrointestinal motility.
Because piperazine kills only the adult roundworms and not the immature stages, it should be given twice, two to three weeks apart.
I take my Interceptor once a month, throughout the year. For more on why it’s better than piperazine, visit www.askthevetspets.com and search Interceptor.
