Uses

Atovaquone is used to prevent or treat a serious lung infection called Pneumocystis pneumonia (PCP). This medication helps to stop infection symptoms such as fever, cough, tiredness, and shortness of breath.

How to Use This Medication

Shake the bottle gently but well before each dose. Carefully measure the dose using a special measuring device/spoon. Do not use a household spoon because you may not get the correct dose.

To treat PCP, take this medication by mouth with food as directed by your doctor, usually twice daily for 21 days. To prevent PCP, take this medication with food usually once a day as directed. Atovaquone must be taken with food so your body can absorb as much of the medication as possible so it can work well.

Children's dosage is also based on age and weight.

This medication works best when the amount of medicine in your body is kept at a constant level. If you take this drug twice a day, take it at evenly spaced intervals about 12 hours apart. If you take this medication once a day, take it at the same time each day.

Continue to take this medication for the full time prescribed, even if symptoms disappear after a few days. Stopping the medication too early may result in a return of the infection.

Tell your doctor if you develop symptoms of PCP, or if your condition lasts or gets worse.
