Albendazole Dosage for Cystic Hydatid Disease (Adults and Children)
Albendazole is recommended at 10–15 mg/kg/day given in two divided doses for cystic echinococcosis (hydatid disease). [1] The usual regimen is 28 days of albendazole followed by a 14-day albendazole-free interval for a total of 3 cycles. [2]
Medication Selection Algorithm
- Weight-based dosing is recommended using 15 mg/kg/day for patients weighing <60 kg and a fixed maximum daily dose of 400 mg twice daily for patients weighing ≥60 kg. [2]
- Dose division into twice-daily dosing with meals is recommended. [2]
Treatment Initiation Thresholds
- Treatment is typically administered as a structured cycle regimen (28 days on treatment, 14 days off treatment) for 3 cycles. [2]
Target Dosing (Dose Per Body Weight and Maximum Dose)
- 10–15 mg/kg/day in two divided doses is recommended for cystic echinococcosis. [1]
- 15 mg/kg/day in divided doses twice daily with meals is recommended for patients weighing <60 kg, with a maximum total daily dose of 800 mg. [2]
- 400 mg twice daily with meals is recommended for patients weighing ≥60 kg. [2]
Treatment Duration and Cycle Structure
- Hydatid disease treatment is administered as 28-day cycles followed by 14-day albendazole-free intervals for a total of 3 cycles. [2]
Administration Considerations
- Albendazole should be taken with food to improve bioavailability. [1]
- Two divided daily doses are recommended (twice daily dosing). [1]
Common Pitfalls to Avoid
- Exceeding 800 mg/day total (for patients <60 kg) is inconsistent with the weight-based maximum dosing described in the U.S. prescribing information. [2]
- Using an uninterrupted regimen without the recommended 14-day albendazole-free intervals is inconsistent with the labeled cycle schedule for hydatid disease. [2]
