How Does Moxifloxacin Eye Drop Work?

Moxifloxacin eye drops work by killing the bacteria that cause eye infections. The active ingredient, moxifloxacin, interferes with the bacteria’s DNA replication process by inhibiting enzymes called DNA gyrase and topoisomerase IV. Without these enzymes, the bacteria cannot grow, multiply or repair themselves, leading to their death.

This helps clear up the infection quickly and prevents it from spreading or getting worse. It starts working within a few days of consistent use and as prescribed.

Uses of Moxifloxacin Eye Drops

Moxifloxacin eye drops are used to treat bacterial infections of the eye. They help relieve symptoms quickly by killing the bacteria. Some common uses include:

Bacterial Conjunctivitis:
One of the most common reasons for prescribing moxifloxacin. It treats redness, irritation and discharge caused by bacterial infection.
Prevention of Eye Infections After Surgery:
Doctors may prescribe it after cataract or LASIK surgery to prevent infection and aid in faster healing.
Corneal Ulcers:
In some cases, moxifloxacin is used to treat corneal ulcers caused by bacterial invasion of the eye’s surface.
Blepharitis:
Infections affecting the eyelids can also be treated with moxifloxacin drops if bacterial involvement is present.

Moxifloxacin Eye Drops Uses for Babies

Moxifloxacin eye drops may be prescribed for infants and babies to treat bacterial eye infections, but only under a paediatrician’s or eye specialist’s supervision.

Note: Moxifloxacin eye drops are usually considered safe for babies older than 1 year, but dosing and duration should be strictly as prescribed. The doctor will consider the baby’s age, weight, and type of infection before prescribing it.

The dosage of Moxifloxacin eye drops depends on the type and severity of the eye infection, as well as your doctor’s recommendation.

For Post-Surgical Infection Prevention:
Your doctor may recommend using one drop in the eye every 4 to 6 hours, starting before or after eye surgery and continuing for several days to prevent bacterial infection.
Missed Dose:
