Question:
Has anyone had mental/mood changes when taking the oral suspension of Omnicef? If so, how serious of a side effect is this?

Answer:
In clinical trials, treated with the recommended dose of cefdinir capsules (600 mg/day), most adverse events were mild and self-limiting. No deaths or permanent disabilities were attributed to cefdinir.

One hundred forty-seven of 5093 (3%) patients discontinued medication due to adverse events thought by the investigators to be possibly, probably, or definitely associated with cefdinir therapy. The discontinuations were primarily for gastrointestinal disturbances, usually diarrhea or nausea.

Nineteen of 5093 (0.4%) patients were discontinued due to rash thought related to cefdinir administration. Nevertheless, because mental/mood swings is not a known or listed side effect of CEFDINIR (Omnicef®), you should report this to your doctor or health care provider.

Hope this answers your question!
