For the treatment of the following gastrointestinal tapeworms and roundworms in adult dogs and puppies.
Ascarids: Toxocara canis, Toxascaris leonina (adult and late immature forms).
Hookworms: Uncinaria stenocephala, Ancylostoma caninum (adults).

Tapeworms: Echinococcus spp., Taenia spp., Dipylidium caninum (adult and immature forms).

Dosage and administration

The recommended dose rates are: 15 mg/kg bodyweight febantel, 5 mg/kg pyrantel (as embonate) and 5 mg/kg praziquantel. This is equivalent to 1 tablet of Cestem® Flavoured for medium and small dogs per 10 kg bodyweight or 1 tablet of Cestem® Flavoured for large dogs per 18-35kg, in one administration.
Dosages are as follows:
3-5 kg = ½ Cestem® Flavoured tablet for medium and small dogs
>5-10 kg = 1 Cestem® Flavoured tablet for medium and small dogs
>10-15 kg = 1½ Cestem® Flavoured tablet for medium and small dogs
>15-20 kg = 2 Cestem® Flavoured tablet for medium and small dogs
17.5 kg = ½ Cestem® Flavoured tablet for large dogs
>17.5-35 kg = 1 Cestem® Flavoured tablet for large dogs
>35-52.5 kg = 1½ Cestem® Flavoured tablet for large dogs
>52.5-70 kg = 2 Cestem® Flavoured tablet for large dogs
The smaller tablet size, Cestem® for medium and small dogs, should be used to achieve accurate dosing in dogs weighing less than 17.5 kg.
For oral administration, the tablets can be given to the dog with or without food. No starvation is needed before or after treatment. To ensure administration of a correct dose, body weight should be determined as accurately as possible. The dosing program should be established by the veterinary surgeon.
Puppies should be treated at 2 weeks of age and every 2 weeks until 12 weeks of age. Thereafter they should be treated at 3 month intervals. It is advisable to treat the bitch at the same time as the puppies.
For the control of Toxocara canis, nursing bitches should be dosed 2 weeks after giving birth and every two weeks until weaning.
For routine worm control adult dogs should be treated every 3 months. In case of confirmed single infestation by cestode or by nematode, a monovalent product containing a cestocide or a nematocide alone should be preferred.
For routine treatment a single dose is recommended.
In the event of heavy roundworm infestation a repeat dose should be given after 14 days.
If an infestation caused by Echinococcus (E. granulosus) is detected in dogs, a repetition of the treatment is recommended for safety purpose.

Contra-indications, warnings, etc

Do not use in animals with a known sensitivity to the active ingredients or to any of the excipients.
Parasite resistance to any particular class of anthelmintic may develop following frequent, repeated use of anthelmintic of that class.
Fleas serve as intermediate hosts for one common type of tapeworm – Dipylidium caninum. Tapeworm infestation may reoccur unless control of intermediate hosts such as fleas, mice etc is undertaken.
The product is not recommended for use in puppies of less than 3 kg bodyweight.
Use during pregnancy and lactation
Do not use in pregnant bitches during the first 4 weeks of pregnancy.
The product may be used during lactation.
Do not use simultaneously with piperazine, as the anthelmintic effects of pyrantel and piperazine may be antagonized.
Plasma concentrations of praziquantel may be decreased by concomitant administration with drugs that increase the activity of cytochrome P-450 enzymes (e.g. dexamethasone, phenobarbital). Concurrent use with other cholinergic compounds can lead to toxicity.
In safety studies, single doses of 5 times (4 times in very young puppies) the recommended dose or greater gave rise to occasional vomiting.
Special precautions to be taken by the person administering the medicinal product to animals
Wash hands after administration to the animal.
In case of accidental ingestion, seek medical advice immediately and show the package leaflet or the label to the physician.
People with known hypersensitivity to any of the ingredients should avoid contact with the veterinary medicinal product.
Any unused veterinary medicinal product or waste materials derived from such veterinary medicinal products should be disposed of in accordance with local requirements.

Further information

Pharmacodynamic properties
In this fixed combination pyrantel and febantel act against all relevant nematodes (ascarids, hookworms, and whipworms) in dogs. In particular the activity spectrum covers Toxocara canis, Toxascaris leonina, Uncinaria stenocephala, Ancylostoma caninum and Trichuris vulpis. This combination shows synergistic activity in the case of hookworms and febantel is effective against T. vulpis.
The spectrum of activity of praziquantel covers all important cestode species in dogs, in particular Taenia spp, Dipylidium caninum, Echinococcus granulosus and Echinococcus multilocularis. Praziquantel acts against all adult and immature forms of these parasites.
Praziquantel is very rapidly absorbed through the parasite’s surface and distributed throughout the parasite. Both in vitro and in vivo studies have shown that praziquantel causes severe damage to the parasite integument, resulting in the contraction and paralysis of the parasites. There is an almost instantaneous tetanic contraction of the parasite musculature and a rapid vacuolisation of the syncytial tegument. This rapid contraction has been explained by changes in divalent cation fluxes, especially calcium.
Pyrantel acts as a cholinergic agonist. Its mode of action is to stimulate nicotinic cholinergic receptors of the parasite, induce spastic paralysis of the nematodes and thereby allow removal from the gastro- intestinal (GI) system by peristalsis.
Within the mammalian system febantel undergoes ring closure forming fenbendazole and oxfendazole. It is these chemical entities which exert the anthelmintic effect by inhibition of tubulin polymerisation. Formation of microtubules is thereby prevented, resulting in disruption of structures vital to the normal functioning of the helminth. Glucose uptake, in particular is affected, leading to a depletion in cell ATP. The parasite dies upon exhaustion of its energy reserves, which occurs 2-3 days later.
Pharmacokinetic particulars
After oral administration to dogs, praziquantel is extensively and quickly absorbed from the gastro-intestinal tract. Maximum plasma concentration of 752 µg/L is obtained in less than 2 hours. It is rapidly and extensively metabolised in the liver into hydroxylated derivatives of the parent compound, then rapidly eliminated, mainly in urine.
After oral administration to dogs, febantel is moderately absorbed from the gastro-intestinal tract. Febantel is rapidly metabolised in the liver into fenbendazole and its hydroxy and oxidative derivatives like oxfendazole. Maximum plasma concentration of fenbendazole (173 µg/L) is obtained after about 5 hours. Maximum plasma concentration of oxfendazole (147 µg/L) is obtained after about 7 hours. The excretion occurs mainly in the faeces.
After oral administration to dogs, pyrantel embonate is poorly absorbed. Maximum plasma concentration of 79 µg/L is obtained after about 2 hours. It is rapidly and extensively metabolised in the liver, then rapidly excreted, mainly in the faeces (the unchanged form) and in urine (the metabolites).

Katherine Lanson

  • VioVet customer since 2013
  • From: Greater Manchester, United Kingdom

On the back of the wormers box it says do not give with piperazine compounds. What are these please?

  • Brand Manager

Hi Katherine, piperazine compounds are active ingredients used in some wormers. Cestem contains ingredients which may be inhibited by piperazine (making the treatment less effective), which is why it is important to ensure these two drugs are not given together. If you are not giving your dog any other worming medication, this won't be a problem.
