Albenza FDA Prescribing Information: Side Effects
The adverse event profile of albendazole differs between hydatid disease and neurocysticercosis. Adverse events occurring with a frequency of ≥ 1% in either disease are described in the table below.
These symptoms were usually mild and resolved without treatment. Treatment discontinuations were predominantly due to leukopenia (0.7%) or hepatic abnormalities (3.8% in hydatid disease). The following incidence reflects events that were reported by investigators to be at least possibly or probably related to albendazole.
Adverse Event Incidence ≥ 1% in Hydatid Disease and Neurocysticercosis
|Adverse Event||Hydatid Disease||Neurocysticercosis|
|Abnormal Liver Function Tests||15.6||< 1.0|
|Raised Intracranial Pressure||0||1.5|
|Reversible Alopecia||1.6||< 1.0|
The following adverse events were observed at an incidence of < 1%:
Blood and Lymphatic System Disorders: Leukopenia. There have been rare reports of granulocytopenia, pancytopenia, agranulocytosis, or thrombocytopenia (see WARNINGS). Patients with liver disease, including hepatic echinococcosis, appear to be more at risk of bone marrow suppression (see WARNINGS and PRECAUTIONS).
Postmarketing Adverse Reactions: In addition to adverse events reported from clinical trials, the following events have been identified during world-wide post-approval use of ALBENZA (albendazole) . Because they are reported voluntarily from a population of unknown size, estimates of frequency cannot be made. These events have been chosen for inclusion due to a combination of their seriousness, frequency of reporting, or potential causal connection to ALBENZA (albendazole) .
Blood and Lymphatic System Disorders: Aplastic anemia, bone marrow suppression, neutropenia.
Renal and Urinary Disorders: Acute renal failure.
