Take Omnicef exactly as it was prescribed for you. Do not take the medication in larger amounts, or take it for longer than recommended by your doctor. Follow the directions on your prescription label.

You may take this medication with or without food.

Shake the oral suspension (liquid) well just before you measure a dose. To be sure you get the correct dose, measure the liquid with a marked measuring spoon or medicine cup, not with a regular table spoon. If you do not have a dose-measuring device, ask your pharmacist for one.

This medication can cause you to have false results with certain medical tests, including urine glucose (sugar) tests. Tell any doctor who treats you that you are using Omnicef.

Take Omnicef for the entire length of time prescribed by your doctor. Your symptoms may get better before the infection is completely treated. Omnicef will not treat a viral infection such as the common cold or flu. Store the capsules at room temperature away from moisture, heat, and light. Store Omnicef oral liquid in the refrigerator. Do not allow it to freeze. Throw away any unused medication that is older than 14 days.
