Atovaquone tablets may be crushed if necessary to make it easier to swallow.

Because atovaquone tablets and oral suspension do not produce the same amount of medicine in the blood, the tablets and the suspension cannot be switched and used in place of each other.

  • Shake the bottle gently before using atovaquone.

  • Do not use after the expiration date on the label since the medicine may not work properly after that date. Check with your pharmacist if you have any questions about this .

To help clear up your infection completely, keep taking your medicine for the full time of treatment, even if you begin to feel better after a few days. If you stop taking this medicine too soon, your symptoms may return.
