The main use of Vigamox is to treat pink eye (conjunctivitis) that is caused by a bacterial infection. The antibiotic eye drop works by interfering with two important enzymes that are necessary for bacteria to multiply. It can be used in children as young as one year old. In some cases, a healthcare provider may recommend this product "off-label," such as for preventing eye infections.
What Is Vigamox Used For?Vigamox® (moxifloxacin eye drops) is an antibiotic eye drop used for treating "pink eye" due to bacterial infections. Pink eye is a layman's term for conjunctivitis, which is inflammation of the conjunctiva, the thin piece of tissue that covers the whites of the eyes and the inner eyelids. When the conjunctiva becomes inflamed, it looks pink or red from a distance.
There are several reasons why the conjunctiva can become inflamed. The two most common reasons are because of an infection with a virus (known as viral conjunctivitis) or an allergic reaction (allergic conjunctivitis). An infection with bacteria (bacterial conjunctivitis) or something that irritates the eye, such as an eyelash, can also cause the conjunctiva to become inflamed.
Because Vigamox is an antibiotic, it is effective only for treating bacterial conjunctivitis. It will not be effective for treating viral eye infections or eye redness due to other causes.
How Does It Work?Vigamox belongs to a class of antibiotics known as fluoroquinolones, also known as "quinolones." These medications work by interfering with two important bacterial enzymes: topoisomerase IV and DNA gyrase. These enzymes are necessary for bacteria to be able to copy and repair DNA, which are important steps required in order for bacteria to multiply.
