( 2 ) See additional important information in the Full Prescribing Information. ( 2 ) 2.1 Dosage Dosing of Albendazole Tablets will vary depending upon the indication. Albendazole Tablets may be crushed or chewed and swallowed with a drink of water. Albendazole Tablets should be taken with food [ see Clinical Pharmacology ( 12.3 ) ]. Table 1: Albendazole Tablets Dosage Indication Patient Weight Dose Duration Hydatid Disease 60 kg or greater 400 mg twice daily, with meals 28‑day cycle followed by a 14‑day albendazole‑free interval, for a total of 3 cycles Less than 60 kg 15 mg/kg/day given in divided doses twice daily with meals (maximum total daily dose 800 mg) Neurocysticercosis 60 kg or greater 400 mg twice daily, with meals 8 to 30 days Less than 60 kg 15 mg/kg/day given in divided doses twice daily with meals (maximum total daily dose 800 mg) 2.2 Concomitant Medication to Avoid Adverse Reactions Patients being treated for neurocysticercosis should receive appropriate steroid and anticonvulsant therapy as required. Oral or intravenous corticosteroids should be considered to prevent cerebral hypertensive episodes during the first week of treatment [ see Warnings and Precautions ( 5.3 ) ]. 2.3 Monitoring for Safety Before and During Treatment Monitor blood counts at the beginning of each 28‑day cycle of therapy, and every 2 weeks while on therapy with Albendazole Tablets in all patients [ see Warnings and Precautions ( 5.1 ) ]. Monitor liver enzymes (transaminases) at the beginning of each 28‑day cycle of therapy, and at least every 2 weeks during treatment with Albendazole Tablets in all patients [ see Warnings and Precautions ( 5.5 ) ]. Obtain a pregnancy test in females of reproductive potential prior to therapy [ see Warnings and Precautions ( 5.2 ) ].

WARNINGS AND PRECAUTIONS Bone Marrow Suppression: Fatalities have been reported due to bone marrow suppression; monitor blood counts in all patients at the beginning of each 28‑day cycle of therapy, and every 2 weeks while on therapy. Discontinue Albendazole Tablets if clinically significant changes in blood counts occur. ( 5.1 , 5.4 ) Embryo-Fetal Toxicity: May cause fetal harm. Pregnancy testing is recommended for females of reproductive potential prior to therapy. Advise females of reproductive potential of the potential risk to a fetus and to use an effective method of contraception. ( 2.3 , 5.2 , 8.1 , 8.3 ) Risk of Neurologic Symptoms: Neurocysticercosis patients may experience cerebral hypertensive episodes, seizures or focal neurologic deficits after initiation of therapy; begin appropriate steroid and anticonvulsant therapy. ( 5.3 ) Risk of Retinal Damage in Retinal Cysticercosis: Cases of retinal involvement have been reported; examine the patient for the presence of retinal lesions before initiating therapy for neurocysticercosis. ( 5.4 ) Hepatic Effects. Elevations of liver enzymes may occur. Monitor liver enzymes before the start of each treatment cycle and at least every 2 weeks while on Albendazole Tablets therapy and discontinue if clinically significant elevations occur. ( 5.5 ) 5.1 Bone Marrow Suppression Fatalities associated with the use of Albendazole Tablets have been reported due to granulocytopenia or pancytopenia. Albendazole Tablets may cause bone marrow suppression, aplastic anemia, and agranulocytosis. Monitor blood counts at the beginning of each 28‑day cycle of therapy, and every 2 weeks while on therapy with Albendazole Tablets in all patients. Patients with liver disease and patients with hepatic echinococcosis are at increased risk for bone marrow suppression and warrant more frequent monitoring of blood counts. Discontinue Albendazole Tablets if clinically significant decreases in blood cell counts occur. 5.2 Embryo-Fetal Toxicity Based on findings from animal reproduction studies, Albendazole Tablets may cause fetal harm when administered to a pregnant woman. Embryotoxicity and skeletal malformations were reported in rats and rabbits when treated during the period of organogenesis (at oral doses approximately 0.1 to 0.6 times the recommended human dose normalized for total body surface area). Advise pregnant women of the potential risk to a fetus. Pregnancy testing is recommended for females of reproductive potential prior to initiating Albendazole Tablets [ see Dosage and Administration ( 2.3 ) ]. Advise females of reproductive potential to use an effective method of contraception during treatment with Albendazole Tablets and for 3 days after the final dose [ see Use in Specific Populations ( 8.1 , 8.3 ) and Clinical Pharmacology ( 12.3 ) ]. 5.3 Risk of Neurologic Symptoms in Neurocysticercosis Patients being treated for neurocysticercosis should receive steroid and anticonvulsant therapy to prevent neurological symptoms (e.g. seizures, increased intracranial pressure and focal signs) as a result of an inflammatory reaction caused by death of the parasite within the brain. 5.4 Risk of Retinal Damage in Patients with Retinal Neurocysticercosis Cysticercosis may involve the retina. Before initiating therapy for neurocysticercosis, examine the patient for the presence of retinal lesions. If such lesions are visualized, weigh the need for anticysticeral therapy against the possibility of retinal damage resulting from inflammatory damage caused by albendazole‑induced death of the parasite. 5.5 Hepatic Effects In clinical trials, treatment with Albendazole Tablets has been associated with mild to moderate elevations of hepatic enzymes in approximately 16% of patients. These elevations have generally returned to normal upon discontinuation of therapy. There have also been case reports of acute liver failure of uncertain causality and hepatitis [ see Adverse Reactions ( 6 ) ]. Monitor liver enzymes (transaminases) before the start of each treatment cycle and at least every 2 weeks during treatment. If hepatic enzymes exceed twice the upper limit of normal, consideration should be given to discontinuing Albendazole Tablets therapy based on individual patient circumstances. Restarting Albendazole Tablets treatment in patients whose hepatic enzymes have normalized off treatment is an individual decision that should take into account the risk/benefit of further Albendazole Tablets usage. Perform laboratory tests frequently if Albendazole Tablets treatment is restarted. Patients with elevated liver enzyme test results are at increased risk for hepatotoxicity and bone marrow suppression [ see Warnings and Precautions ( 5.1 ) ]. Discontinue therapy if liver enzymes are significantly increased or if clinically significant decreases in blood cell counts occur. 5.6 Unmasking of Neurocysticercosis in Hydatid Patients Undiagnosed neurocysticercosis may be uncovered in patients treated with Albendazole Tablets for other conditions. Patients with epidemiologic factors who are at risk for neurocysticercosis should be evaluated prior to initiation of therapy.
