Atovaquone
Summary
Atovaquone is used to treat and prevent infections like Pneumocystis pneumonia, which is a type of lung infection, and malaria, which is a disease caused by parasites transmitted through mosquito bites.
Atovaquone works by interfering with the energy production of parasites, which are organisms causing infections. It disrupts their ability to produce energy, which is essential for their survival, helping to eliminate them from the body.
The usual dose for adults to prevent Pneumocystis pneumonia is 1,500 mg once daily with food. The dose may vary for treatment or other conditions. Always follow your doctor's instructions for the correct dosage.
Common side effects of Atovaquone include nausea, which is feeling sick to your stomach, diarrhea, which is loose or watery stools, and headache, which is pain in the head.
Atovaquone should be taken with food to ensure proper absorption. Avoid it if allergic, which means having a bad reaction, to its ingredients. It can cause liver problems, so regular monitoring is needed.
