Active Ingredients in WormersDeworming your pets on a regular basis is crucial for their overall health. Wormers often have different active ingredients, so it's important to know what each active ingredient does. Here are the top five active ingredients in wormers:
Pyrantel PamoateA very safe and effective ingredient to treat roundworms, hookworms and pinworms in dogs. Need to dose a second or even third time, two to four weeks apart, to eliminate all stages of the worms.
Roundworms attach to your pet's intestines with their little teeth. Sentry® WormX Liquid Dewormer contains pyrantel pamoate and works by paralyzing the worms, so they release their grip and pass in the feces. The worms remain alive in the soil for a short period of time.
PiperazineEffective against two types of roundworms in dogs and cats. For maximum effectiveness, must be administered at least two times (10 to 14 days apart) to the pet.
FenbendazoleA very broad spectrum anthelmintic (dewormer) used in both small and large animals. In dogs, fenbendazole is effective against roundworms, hookworms, whipworms and even giardia. Treatment is once a day for three consecutive days.
Fenbendazole works by diminishing the parasites' energy reserves and limiting their ability to eliminate waste.
PraziquantelThe drug of choice for treating adult tapeworm infections in both dogs and fish. Does not kill the tapeworm eggs, so there is a potential for reinfection. To prevent this from happening, pets should be retreated on a regular basis.
Praziquantel eliminates the tapeworms' ability to prevent digestion by your pet. Therefore, the tapeworms disintegrate and become absorbed into your pet's body.
IvermectinMost commonly used as a monthly preventative for heartworm in dogs and cats. It is also effective against external parasites such as lice, mange and ear mites.
Medications with ivermectin only work on parasites that your pet has been exposed to in the preceding month, so it is recommended that heartworm prevention be used year round. Ivermectin works by interfering with the central nervous system of the heartworm larva.
