- Do not take an antacid that has magnesium or aluminum in it within 2 hours before or after you take Omnicef suspension.

Important safety information:
- Omnicef suspension may cause drowsiness or dizziness. These effects may be worse if you take it with alcohol or certain medicines. Use Omnicef suspension with caution. Do not drive or perform other possibly unsafe tasks until you know how you react to it.
- Omnicef suspension only works against bacteria; it does not treat viral infections (eg, the common cold).
- Be sure to use Omnicef suspension for the full course of treatment. If you do not, the medicine may not clear up your infection completely. The bacteria could also become less sensitive to this or other medicines. This could make the infection harder to treat in the future.
- Long-term or repeated use of Omnicef suspension may cause a second infection. Tell your doctor if signs of a second infection occur. Your medicine may need to be changed to treat this.
- Mild diarrhea is common with antibiotic use. However, a more serious form of diarrhea (pseudomembranous colitis) may rarely occur. This may develop while you use the antibiotic or within several months after you stop using it. Contact your doctor right away if stomach pain or cramps, severe diarrhea, or bloody stools occur. Do not treat diarrhea without first checking with your doctor.
- If you are taking Omnicef suspension and a product that contains iron, your stools may turn a reddish color. This is normal and not a cause for concern.
- Diabetes patients - Omnicef suspension has sucrose in it. It may affect your blood sugar. Check blood sugar levels closely. Ask your doctor before you change the dose of your diabetes medicine.
- Diabetes patients - Omnicef suspension may cause the results of some tests for urine ketones or glucose to be wrong. Ask your doctor before you change your diet or the dose of your diabetes medicine.
- Omnicef suspension may interfere with certain lab tests (eg, Coombs tests). Be sure your doctor and lab personnel know you are using Omnicef suspension.
- Omnicef suspension should be used with extreme caution in CHILDREN younger than 6 months old; safety and effectiveness in these children have not been confirmed.
