Key takeaways
Moxifloxacin (Vigamox) and neomycin/polymyxin/hydrocortisone (Cortisporin) are both prescription medications, but they treat different types of infections and are used in different parts of the body. Moxifloxacin (Vigamox) is a fluoroquinolone antibiotic used as eye drops to treat bacterial conjunctivitis (pink eye). It works by blocking proteins that bacteria need to grow and survive. On the other hand, neomycin/polymyxin/hydrocortisone (Cortisporin) is a combination of two antibiotics and a corticosteroid used as ear drops to treat outer ear infections. The antibiotics kill bacteria, while the corticosteroid reduces swelling and itching. Moxifloxacin (Vigamox) is typically used three times a day for seven days, while neomycin/polymyxin/hydrocortisone is used three or four times a day, with the dosage varying for adults and children. Both medications are available in generic forms, making them more affordable. However, neomycin/polymyxin/hydrocortisone carries a risk of hearing loss if used for more than 10 days, while moxifloxacin (Vigamox) can cause eye discomfort and should not be used with contact lenses.
