Vigamox eye drops are a prescription medication commonly used to treat bacterial eye infections. The active ingredient in Vigamox is moxifloxacin, which belongs to a class of antibiotics known as fluoroquinolones. These eye drops work by inhibiting the growth of bacteria, thereby eliminating the infection. Vigamox is specifically designed for ocular use and is effective against a broad spectrum of bacteria that can cause conjunctivitis or other bacterial eye infections.
