Moxifloxacin with dexamethasone

Moxifloxacin with dexamethasone eye drops, sold under the 4 quin-D brand and produced in India, are supplied in a sterile 5 g container for ophthalmic use. The formulation pairs moxifloxacin, a broad-spectrum fluoroquinolone antibiotic, with dexamethasone, a potent corticosteroid, to treat bacterial eye infections while reducing inflammation. Because the steroid can increase intra-ocular pressure and mask worsening infection, the drops should be administered only under professional medical guidance and discontinued if severe irritation or pressure elevation occurs.
