There are 3 alcohol/food/lifestyle interactions with atazanavir.

Minor

Caffeine atazanavir

Minor Drug Interaction

Information for this minor interaction is available on the professional version.

Moderate

atazanavir food

Moderate Food Interaction

Food can enhance the levels of atazanavir in your body. To ensure maximal oral absorption, atazanavir should be administered with or immediately after a meal. This will make it easier for your body to absorb the medication.

Moderate

High Cholesterol (Hyperlipoproteinemia, Hypertriglyceridemia, Sitosterolemia)

Moderate Potential Hazard, High plausibility

PIs - hyperlipidemia

Hyperlipidemia has been observed in 10% of patients receiving ritonavir during clinical trials. Increases of 30% to 40% from baseline have been reported for total cholesterol and 200% to 300% or more for triglycerides. These effects have also been reported during postmarketing experience with other protease inhibitors (PIs) but may be the most dramatic with ritonavir. The clinical significance of these elevations is unclear. Severe hyperlipidemia is known to sometimes cause pancreatitis. In addition, some patients have reportedly developed symptomatic atherosclerosis and coronary artery disease after initiating PI treatment. Patients with preexisting hyperlipidemia may require closer monitoring during PI therapy, and adjustments made accordingly in their lipid-lowering regimen. PI therapy should be administered cautiously in patients with coronary artery disease or a history of ischemic heart disease.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
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.
Unknown No interaction information available.
