THERE ARE NO CONTRAINDICATIONS TO THE USE OF NICLOSAMIDE AS A TENIACIDE.

Therapeutic Use Niclosamide in the free-base form only is used primarily as a cestocide and to a lesser extent as a trematocide. The drug is formulated as a chewable tablet containing 500 mg of niclosamide. It is very effective against tapeworrn infections caused by Taenia saginata, Taenia solium, and Diphyllobothrium latum; tapeworms such as Hymenolepis diminuta, Hymenolepis nana, and Dipylidium caninum are somewhat more recalcitrant. For infections of Taenia saginata, Taenia solium, and Diphyllobothrium latum, single oral dosages of 2 gm (adult), 1.5 gm (child > 34 kg), and 1.0 gm (child 11-34 kg) are recommended. 0ther tapeworms may require repeated treatment for example, 2 gm/day in single daily doses for 7 days (adults), 1.5 gm given in a single dose on the first day followed by 1 gm/day for the next 6 days (child > 34 kg), and 1 gm given in a single dose on the first day followed by 500 mg/day for next 6 days (child 11-34 kg). Safety for use in children under 2 years of age has not been established. Since niclosamide is active only against intestinal cestodes, it is not effective for treatment of cysticercosis. As a trematocide, niclosamide is active mainly against flukes such as Fasciolopsis buski in the intestines.

VET: DO NOT TREAT LACTATING ANIMALS.
Rossoff, I.S. Handbook of Veterinary Drugs. New York: Springer Publishing Company, 1974., p. 384
... It is important to note that the lethal action of the drug against the adult worn does not extend to the ova. Thus, use of niclosamide in Taenia solium infections may expose the patient to the risk of cysticercosis, since, following digestion of the dead segments, viable ova will be liberated into the lumen of the gut. It is desirable to give an adequate purge within 3 to 4 hours after the drug has been given, to clear the bowel of all dead segments before they can be digested.
Gilman, A.G., T.W. Rall, A.S. Nies and P. Taylor (eds.). Goodman and Gilman's The Pharmacological Basis of Therapeutics. 8th ed. New York, NY. Pergamon Press, 1990., p. 965
The drug causes segments to disintegrate, releasing viable eggs; hence, if used against pork tapeworm, a purge should be given 1 or 2 hr after treatment. Untoward effects occur only occasionally; nausea and abdominal pain have been reported.

For the treatment of tapeworm and intestinal fluke infections: Taenia saginata (Beef Tapeworm), Taenia solium (Pork Tapeworm), Diphyllobothrium latum (Fish Tapeworm), Fasciolopsis buski (large intestinal fluke). Niclosamide is also used as a molluscicide in the control of schistosomiasis.
Niclosamide is an antihelminth used against tapeworm infections. It may act by the uncoupling of the electron transport chain to ATP synthase. The disturbance of this crucial metabolic pathway prevents creation of adenosine tri-phosphate (ATP), an essential molecule that supplies energy for metabolism.

When male and female volunteers each were treated orally with 2000 mg of radiocarbon-labeled niclosamide, between 2 and 25% of the dose was eliminated in the urine over a 4-day period; the remainder was found in the feces. Elimination of niclosamide equivalents was essentially complete after 1-2 days. Maximal niclosamide equivalents in serum ranged from 0.25 to 6.0 ppm; the variation associated with this parameter was attrributed to differential rates of absorption among the individual.

In warm-blooded organisms, the nitro group is reduced to an amino group (5,2'-dichloro-4-aminosalicylanilide).
Hartley, D. and H. Kidd (eds.). The Agrochemicals Handbook. Old Woking, Surrey, United Kingdom: Royal Society of Chemistry/Unwin Brothers Ltd., 1983., p. A297/Oct 83
Pregnant rats were treated orally with niclosamide at 1000 mg/kg on day 13, 19, or 20 of gestation, and rats were sacrificed at 4, 8, 16, or 24 hr posttreatment. Highest concentrations of niclosamide and 2,5'-dichloro-4'-aminosalicylanilide were detected in liver and kidney 8 hr after treatment. Niclosamide, but not its amino metabolite, was present in fetuses from rats treated on day 13, whereas both compounds were found in fetuses from rats treated on day 19 or 20. It was suggested that 19- and 20-day-old fetuses, but not 13-day-old fetuses, were able to metabolize niclosamide.

Niclosamide ... is absorbed from the gastrointestinal tract, and mutagenic metabolites are excreted in the free form and as conjugated glucuronides. as in the case of other secondary amides, phase I metabolism of niclosamide may result in hydrolytic cleavage of the amide bond, giving rise to 5-chlorosalicylic acid and 2-chloro-4-nitroaniline. ...

Niclosamide works by killing tapeworms on contact. Adult worms (but not ova) are rapidly killed, presumably due to uncoupling of oxidative phosphorylation or stimulation of ATPase activity. The killed worms are then passed in the stool or sometimes destroyed in the intestine. Niclosamide may work as a molluscicide by binding to and damaging DNA.
Niclosamide has prominent activity against most of the cestodes that infect man; Enterobius (Oxyuris) vermicularis is also susceptible. At low concn, niclosamide stimulates oxygen uptake by Hymenolepis diminuta, but at higher concn respiration is inhibited and glucose uptake is blocked. The principal action of the drug may be to inhibit anaerobic phosphorylation of adenosine diphosphate (ADP) by the mitochondria of the parasite, an energy producing process that is dependent on CO2 fixation ... .
Gilman, A.G., T.W. Rall, A.S. Nies and P. Taylor (eds.). Goodman and Gilman's The Pharmacological Basis of Therapeutics. 8th ed. New York, NY. Pergamon Press, 1990., p. 965
Cestocidal activity is due to inhibition of absorption of glucose by the tapeworm and uncoupling of the oxidative phosphorylation process in the mitochondria of cestodes. Resultant blocking of the Krebs cycle leads to accumulation of lactic acid, which kills the tapeworm. ... overstimulation of adenosine triphosphatase (ATPase) activity of the mitochondria may be related to cestodal action of niclosamide.
