More Information on Omnicef Interactions

The following sections explain in detail the potentially negative interactions that can occur when Omnicef is taken with any of the drugs listed above.

Probenecid

If you are taking both Omnicef and probenecid, your body may metabolize these drugs differently than intended. This can significantly increase the amount of Omnicef in your system. Your healthcare provider may choose to monitor your progress more closely and adjust your dosage accordingly if this occurs.

Aluminum or Magnesium Antacids

If Omnicef and antacids made with aluminum or magnesium are taken together, less Omnicef may be absorbed into your body. To prevent this interaction, take the antacids at least two hours before or two hours after taking the Omnicef.
