Albendazole Dosing Timing
Albendazole is sometimes prescribed to be taken at night to align dosing with food and meal-related absorption. (dailymed.nlm.nih.gov) Nighttime dosing is also used in some intestinal helminth regimens (particularly pinworm) because host symptoms and egg-laying activity occur at night. (cdc.gov)
Food-Associated Absorption
Albendazole systemic exposure (albendazole sulfoxide) increases after ingestion with a high-fat meal. (dailymed.nlm.nih.gov) Albendazole labeling advises taking the drug with food. (dailymed.nlm.nih.gov) Evening or bedtime administration often results in the dose being taken with the day’s main meal. (dailymed.nlm.nih.gov)
Pinworm Biology and Nighttime Activity
Female pinworms lay eggs at night on the skin around the anus. (cdc.gov) Anal itching from pinworms is commonly worse at night. (medlineplus.gov) Because pinworms’ nocturnal egg-laying drives transmission and symptoms, clinicians frequently schedule treatment to coincide with nighttime patterns used in pinworm care. (cdc.gov)
Practical Implications
Night dosing is consistent with meal-based administration recommendations and the typical timing of symptoms for pinworm infection. (dailymed.nlm.nih.gov) Dosing time should follow the specific regimen provided for the diagnosed parasite. (medlineplus.gov)
