Treatment for Tapeworms in Dogs
There are many different treatment options available for treating Tapeworms in dogs. Though it is possible for a dog to eradicate this infection naturally (through digestion/vomiting of the worm), this is relatively rare. Veterinary medicine has provided us with several different medications that are relatively effective when used to treat Tapeworm in dogs. It's extremely important to follow the instructions of your veterinarian for the most effective treatment method.
Praziquantel
The drug Praziquantel is marketed under names such as Drontal, Droncit, Tradewinds Tapeworm Tablets, and D-Worm. Praziquantel is considered to be highly effective in treating Tapeworm infections, and is proven effective in eradicating several different species of Tapeworm (D. canium, Taenia spp, Echinococcus spp).
Praziquantel is also the only Tapeworm medication that is labeled to be effective against the Echinococcus spp type of Tapeworm. The dosage type (oral, injections, etc) varies with each specific case, as does the dosage amount. Though side effects are relatively rare with the oral form of this medication, they may include sedation, diarrhea, vomiting and the appearance of loss of coordination.
Epsiprantel
The medication Epsiprantel is marketed under the brand name Cestex. Epsiprantel is considered to be one of the more popular drugs used by veterinarians to treat Tapeworm infections. Epsiprantel causes the paralysis of the tapeworm, causing the worm to lose its attachment to a dog's intestine or stomach. This makes the worm susceptible to digestion by a dog's gastrointestinal system.
Epsiprantel is generally seen in an oral tablet form, and is used as a "one-time" treatment (though measures against reinfection may be necessary). This medication is generally prescribed as 2.5mg for every pound of a dog's body weight. Possible side effects include vomiting and diarrhea. Epsiprantel is effective against two species of Tapeworm: D. canium and Taenia spp.
Fenbendazole
This medication is not widely popular in treating Tapeworm infections, though may still be used by veterinarians in special cases. Fenbendazole is marketed under the brand names Panacur and Safe-Guard. In addition to being used against Tapeworms, Fenbendazole is also used for treating medical conditions such as Giardia and flukes. Side effects are very rare, though may include vomiting and diarrhea.
Fenbendazole is available as an "over the counter" medication, though should generally not be used except under the strict guidance of a veterinarian. In most cases, this medication needs to be administered to an infected dog for several days for it to be effective.
