The standard dosage of albendazole can vary depending on the specific infection being treated. For adults and children over two years old, the typical dosage ranges from 400 mg to 800 mg taken once or twice daily, depending on the disease. For certain conditions, a single dose may suffice, while others may require a multi-day regimen. It is essential that patients follow healthcare provider recommendations for dosage and duration of treatment to ensure effectiveness and to minimize the potential for side effects.
