Summary

What this interaction means in plain words
Gemifloxacin and Glimepiride can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Gemifloxacin belongs to Anti Bacterial; Glimepiride belongs to Endocrine.
Why it happens
Fluoroquinolones stimulate pancreatic insulin release by blocking beta-cell ATP-sensitive potassium channels, adding to the sulfonylurea effect.
