4 Quin Ophthalmic Solution

4 Quin Ophthalmic Solution is a prescription eye drop containing moxifloxacin, a fluoroquinolone antibiotic used in the eye. Each drop delivers moxifloxacin as labelled in a sterile solution made by Entod Pharmaceuticals. It is used to treat bacterial eye infections, such as bacterial conjunctivitis, when the infection is caused by susceptible bacteria. Because it is an ophthalmic solution, it is designed for direct use in the eye rather than by mouth.

How it works: Moxifloxacin works by blocking bacterial enzymes that bacteria need to copy and repair their DNA, which stops the germs from multiplying. In 4 Quin Ophthalmic Solution, the liquid form helps the medicine coat the eye surface and act directly where the infection is.

4 Quin Ophthalmic Solution is a single-strength eye drop product, so there are no other 4 Quin brand strengths or forms to compare it with here. As an ophthalmic solution, it is chosen for patients who need local antibiotic treatment in a liquid drop that spreads quickly across the eye surface. A doctor may choose this form when rapid, direct delivery to the infected eye is preferred.

• Bacterial conjunctivitis
• Bacterial eye infection treatment
• Prescription antibiotic eye drops
• Local treatment for susceptible eye bacteria

• Wash your hands before using 4 Quin Ophthalmic Solution.
• Tilt your head back, pull down the lower eyelid, and place the prescribed number of drops into the eye.
• Do not touch the dropper tip to your eye, fingers, or any surface.
• Close your eye gently for 1 to 2 minutes after instilling the drop.
• If you use other eye medicines, wait at least 5 minutes between products unless your doctor tells you otherwise.
• Follow your prescriber's schedule exactly and finish the full course, even if your eye feels better.

Each drop of 4 Quin Ophthalmic Solution provides moxifloxacin as labelled in a sterile ophthalmic solution. The exact number of drops and how many times per day you use it depend on the infection and your doctor's instructions; there is no one-size-fits-all dose for every patient. Do not use more often than prescribed, and do not exceed the amount your doctor recommends.

Do not change your dose or stop the medicine without speaking to your doctor.

Common side effects of Moxifloxacin may include:

• Temporary eye irritation or burning after the drop
• Mild eye discomfort or stinging
• Blurred vision for a short time after use
• Redness of the eye
• Watery eyes
• Dry eye or eye itching

• Use only in the eye; do not swallow 4 Quin Ophthalmic Solution.
• Do not wear contact lenses if your doctor has told you to avoid them during an eye infection.
• If the solution changes color, becomes cloudy, or the bottle tip is contaminated, do not use it.
• Tell your doctor if you have a history of allergy to moxifloxacin or other quinolone antibiotics.
• Use caution if your vision is blurred right after the drop; avoid driving until you can see clearly.
• Tell your doctor if symptoms get worse or do not improve as expected.
• Use this medicine only for a bacterial infection; it will not treat viral or fungal eye problems.

• Other eye drops or ointments may need to be spaced apart by several minutes.
• Tell your doctor about any other prescription or over-the-counter eye medicines you use.
• Systemic quinolone antibiotics may increase the chance of class-related side effects if used together.
• Corticosteroid eye drops may be used with caution only if prescribed together by a clinician.
