Pyrantel Pamoate is prescribed by a veterinarian to treat hookworms and roundworms in pets. Roundworms and hookworms are typically picked up by your pet when it eats infected soil or feces. It is not effective against tapeworms or whipworms.
Your veterinarian may perform a fecal floatation test if they suspect a parasite or as part of a routine check-up. It involves taking a small fecal sample from your dog using a lubricated fecal loop. The feces is then put in a small container with a solution that will allow most of the fecal matter to sink and the parasite eggs to float. A slide is then made of the floating material and examined under a microscope. The slide is then scanned for eggs.
Drugs such as Drontal® contain Pyrantel pamoate in conjunction with another chemical, Praziquantel, which treats for tapeworms. Drontal Plus® contains Pyrantael pamoate, Praziquantel, as well as another drug febantel, which is effective against roundworms, hookworms and whipworms.
SHAKE WELL BEFORE ADMINISTERING
Pyrantel is typically given as a single dose to puppies, kittens, and pets with a positive fecal test for roundworms. It is usually repeated in 2-3 weeks.
How It Works
Roundworms attach to your pet’s intestines with little teeth and feed. Pyrantel works by paralyzing the worms so they release their grip and pass in your pet’s feces. They remain alive in the soil for a short period of time.
Your pet’s body does not absorb Pyrantel very well, so they remain unaffected.
Store in a tightly sealed container at room temperature.
Give the dose as soon as you remember.
