Albendazole and Alcohol / Food Interactions
There is 1 alcohol/food/lifestyle interaction with albendazole:
Moderate Food Interaction
ADJUST DOSING INTERVAL: Food enhances the oral bioavailability of albendazole, which is rapidly converted by hepatocytes and intestinal mucosal cells into the active metabolite, albendazole sulfoxide (ABZSX), following absorption. The proposed mechanism is stimulation of gastric acid secretion, as the absorption of albendazole is thought to be pH-dependent. According to the product labeling, plasma concentrations of ABZSX are up to 5-fold higher on average when albendazole is administered with a fatty meal (fat content approximately 40 g) compared to administration in the fasted state. In one study of six healthy male volunteers, administration of a single 10 mg/kg oral dose of albendazole in combination with a high-fat meal (57 g fat, 1399 kcal) increased the mean ABZSX peak plasma concentration (Cmax) and systemic exposure (AUC) by 6.5- and 9.4-fold, respectively, and delayed the time to reach Cmax (Tmax) from 2.5 to 5.3 hours compared to administration in the fasted state with water. The elimination half-life was not affected.
MONITOR: Grapefruit juice may increase the oral bioavailability of albendazole, which is rapidly converted by hepatocytes and intestinal mucosal cells into the active metabolite, albendazole sulfoxide (ABZSX), following absorption. The proposed mechanism is inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall by certain compounds present in grapefruit. In six healthy male volunteers, administration of a single 10 mg/kg oral dose of albendazole in combination with 250 mL of double-strength grapefruit juice increased the mean ABZSX peak plasma concentration (Cmax) and systemic exposure (AUC) by 3.2- and 3.1-fold, respectively, compared to administration with water. However, because pharmacokinetic interactions involving grapefruit juice are often subject to a high degree of interpatient variability, the extent to which a given patient may be affected is difficult to predict.
MANAGEMENT: To ensure maximal oral absorption, albendazole should be taken with food. Grapefruit juice may also enhance the oral bioavailability of albendazole.

Drug Interaction Classification
The classifications below are a general guideline only. It is difficult to determine the relevance of a particular drug interaction to any individual given the large number of variables.
| Major | Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit. |
| Moderate | Moderately clinically significant. Usually avoid combinations; use it only under special circumstances. |
| Minor | Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan. |
