A person's stomach can have a different gastric pH, or acidity level, at any given time. This results in different absorption rates among people when the drug is taken on an empty stomach.
Food increases the stomach’s acidity and makes albendazole more absorbable. Fatty foods will better assist the absorption of the medicine. In some cases, it can be taken on an empty stomach if the target of infection is intestinal parasites. It is best to follow the directions of your doctor, depending on your diagnosis.
