Microcynah Ophthalmic Gel: A Comprehensive Guide

Microcynah ophthalmic gel is a topical medication used to treat bacterial infections of the eye, including conjunctivitis (pink eye) and blepharitis (inflammation of the eyelids). It contains the active ingredient natamycin, an antifungal antibiotic that fights against a wide range of bacteria.

What is Microcynah Ophthalmic Gel?

Microcynah ophthalmic gel is a sterile, preservative-free gel that is applied directly to the affected eye. The gel contains 5 mg/g of natamycin, which is a polyene antibiotic derived from the fermentation of Streptomyces natalensis.

How Does Microcynah Ophthalmic Gel Work?

Natamycin works by binding to the sterols in the cell membranes of fungi and bacteria, causing the membrane to become leaky and allowing the contents of the cell to leak out. This ultimately leads to the death of the microorganism.

Indications for Use

Microcynah ophthalmic gel is indicated for the treatment of the following bacterial infections of the eye:

• Conjunctivitis (pink eye)
• Blepharitis (inflammation of the eyelids)
• Corneal ulcers (open sores on the cornea)
• Endophthalmitis (infection inside the eye)

Dosage and Administration

Microcynah ophthalmic gel is typically used one to two drops in the affected eye, two to four times per day. The gel should be applied directly to the infected area.

The usual duration of treatment is 7 to 14 days. Treatment should continue for at least 2 days after the symptoms have resolved to prevent recurrence.
