Taking 
atovaquone (tablets or suspension) with fatty food markedly increases its AUC by 2- to 3-fold. 
 Atovaquone/proguanil tablets should be taken with food or an enteral supple- ment, and 
atovaquone suspension should be taken with food. Monitor patients who are unable to tolerate taking 
atovaquone with food for treatment failure; consider 
intravenous treatment in the case of Pneumocystis 
pneumonia.
