Indications:
Echinococcosis Adult: <60 kg: 15 mg/kg daily in 2 divided doses. Max: 800 mg/day. ?60 kg: 400 mg bid. Admin dose for three 28-day cycles w/ a 14-day drug-free interval in between each cycle. Neurocysticercosis Adult: <60 kg: 15 mg/kg daily in 2 divided doses (max: 800 mg/day) for 8-30 days. ?60 kg: 400 mg bid for 8-30 days. Ancylostoma, Ascariasis, Hookworm, Trichostrongylus 400 mg PO once

Dosage (breakdown or, not) :

Adult: 
 Monitor blood counts and liver function. Administer within 7 days of start of normal menstruation in women of childbearing age. Adequate nonhormonal contraceptive measures must be taken during and for 1 mth after therapy. Perform liver function tests and blood counts before and every 2 wk during high dose therapy of hydatid disease. Lactation: unknown, use caution.
Child: 
Albendazole sulfoxide (active metabolite), causes selective degeneration of cytoplasmic microtubules in intestinal and tegmental cells of intestinal helminths and larvae; glycogen is depleted, glucose uptake and cholinesterase secretion are impaired and desecratory substances accumulate intracellulary. ATP production decreases, causing energy depletion, immobilisation and worm death.

Administration:
Increased serum concentrations w/ dexamethasone, praziquantel and cimetidine. Decreased serum concentrations w/ aminoquinoline (antimalarials), carbamazepine, phenobarbital, and phenytoin.

Interaction:
Pregnancy and lactation. Neonates. Hypersensitivity, liver impairment.
