Which medication is contraindicated for use with Avelox?

Avelox, which contains the active ingredient moxifloxacin, is a fluoroquinolone antibiotic. One of the main concerns with the use of fluoroquinolones is their potential for causing cardiac issues, particularly QT interval prolongation. Geodon, or ziprasidone, is an antipsychotic that is also known to prolong the QT interval. When both Avelox and Geodon are used together, the risk of significant cardiac arrhythmias increases, making their concomitant use contraindicated.

This consideration is paramount for patient safety, especially for those who may already have underlying cardiovascular conditions. Other medications listed, such as ibuprofen, amoxicillin, and metformin, do not share this specific interaction concern with Avelox regarding QT prolongation, and therefore do not present the same level of risk when used concurrently.
