Clinical Trials Experience
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
The adverse reaction profile of ALBENZA differs between hydatid disease and neurocysticercosis. Adverse reactions occurring with a frequency of 1% or greater in either disease are described in Table 2 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 adverse reactions that were reported to be at least possibly or probably related to ALBENZA.
Table 2: Adverse Reaction Incidence 1% or Greater in
Hydatid Disease and Neurocysticercosis
|Adverse Reaction||Hydatid Disease||Neurocysticercosis|
|General disorders and administration site conditions|
|Elevated Hepatic Enzymes||16||less than 1|
|Nervous system disorders|
|Dizziness||1||less than 1|
|Raised Intracranial Pressure||0||2|
|Vertigo||1||less than 1|
|Skin and subcutaneous tissue disorders|
|Reversible Alopecia||2||less than 1|
The following adverse events were observed at an incidence of less than 1%:
The following adverse reactions have been identified during post-approval use of ALBENZA. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
Eye Disorders: Vision blurred.
Gastrointestinal Disorders: Diarrhea.
General System Disorders: Asthenia.
Renal and Urinary Disorders: Acute renal failure.
