Mepron (atovaquone) Disease Interactions
There are 2 disease interactions with Mepron (atovaquone):
Atovaquone (Includes Mepron) ↔ Gastrointestinal Absorption
Moderate Potential Hazard, High plausibility
Applies to: Anorexia/Feeding Problems, Malabsorption Syndrome, Diarrhea
Oral bioavailability of atovaquone is limited under fasting conditions, but is increased approximately two-fold when administered with food. Patients with gastrointestinal disorders or eating difficulties may be more likely to have impaired absorption and, consequently, subtherapeutic levels of the drug. Alternative parenteral treatment should be considered for patients unable to achieve adequate plasma concentrations of atovaquone with oral administration.
Atovaquone (Includes Mepron) ↔ Liver Disease
Moderate Potential Hazard, Moderate plausibility
Applies to: Liver Disease
Atovaquone may cause elevated liver function tests. In clinical trials, elevated serum alkaline phosphatase concentrations (> 2.5 times the upper limit of normal, or ULN) were reported in approximately 8% of patients, and elevations in serum ALT and AST (> 5 times ULN) were reported in 6% and 4% of patients, respectively. Increases in serum bilirubin has occurred rarely. Atovaquone also may undergo limited metabolism by the liver. Therapy with atovaquone should be administered cautiously in patients with severe hepatic impairment. Liver function tests should be performed periodically, and therapy withdrawn if significant elevations develop.

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. |
