Optimyxin® contains antibiotics and is used to treat external infections of eye such as bacterial pink eye.

What is Pink Eye?

Pink eye is also known as conjunctivitis and can be caused by an allergy, a bacteria or a virus. Common signs of pink eye are:
• Redness in the white of the eye.
• Swelling of the eyelids.
• Watery eyes.
• Itchiness or a feeling of having sand in the eye.

How is a bacterial Pink Eye treated?

Since bacterial pink eye is very contagious, it is a good idea to begin the treatment with antibiotic eye drops as soon as possible. Optimyxin® treats external infection and helps relive the redness and itchiness associated with bacterial pink eye.

Without treatment, bacterial pink eye may go away by itself in 1 to 2 weeks. To help relieve discomfort, bathe eyes with warm water several times a day and apply warm packs. Clean edges of the infected eye with warm water and cotton balls to remove crusts of dried discharge that may cause the eyelids to stick together.

How do I know I have bacterial Pink Eye?

Pink eye caused by bacteria is accompanied by a thick, yellow-white discharge that may cause the eyelids to stick together, especially upon waking in the morning.

Pink eye caused by virus is often accompanied by a sore throat and/or a tender node in front of the ear, and the discharge tends to be more watery than sticky.

If the pink eye is due to an allergy, it may be accompanied by swollen eyes and other symptoms of allergy, such as a runny nose. It also often occurs during the typical seasons (spring and fall) and usually occurs in both eyes.

How do I use Optimyxin® to treat bacterial Pink Eye?

Instill one or two drops in the affected eye or eyes, two to four times a day for 7 to 10 days. You should begin to see an improvement in your symptoms within 1 to 2 days. Even though the symptoms of the infection may be relieved within 1 to 2 days, you should use Optimyxin® for 7 to 10 days to completely cure the infection.
