4Quin 5 g Ointment

4Quin 5 g Ointment is an eye ointment that contains moxifloxacin, a fluoroquinolone antibiotic used to treat certain bacterial eye infections. Each tube provides 5 g of ointment for use in the eye as directed by a clinician. It works by stopping bacteria from multiplying, which helps clear the infection and reduce symptoms like redness, discharge, and irritation. 4Quin 5 g Ointment is meant for bacterial—not viral or allergic—eye problems.

How it works: Moxifloxacin blocks bacterial enzymes that bacteria need to copy their DNA and survive. In 4Quin 5 g Ointment, this antibiotic is delivered directly to the infected eye so it can act where it is needed.

Because 4Quin 5 g Ointment comes as a 5 g tube, it is a convenient prescription ointment format for short-course eye treatment rather than a pill or injectable form. The ointment base may blur vision for a short time after application, so a doctor may choose it when longer contact time on the eye surface is helpful or when nighttime dosing is preferred.

• Bacterial conjunctivitis
• Bacterial eye infection treatment
• Reducing eye redness and discharge caused by susceptible bacteria
• Prescription antibiotic eye therapy

• Use 4Quin 5 g Ointment exactly as prescribed for the affected eye(s).
• Wash your hands before and after applying the ointment.
• Tilt your head back, pull down the lower eyelid, and place a thin ribbon of ointment into the pocket without touching the tube tip to the eye.
• Close the eye gently for 1 to 2 minutes after applying; vision may be blurred briefly.
• If you use other eye medicines, wait at least 5 to 10 minutes between products unless your doctor tells you otherwise.
• Do not wear contact lenses during an active eye infection unless your prescriber says it is okay.

Each tube of 4Quin 5 g Ointment contains 5 g of ointment, but the amount used per dose is much smaller than the full tube. Dosing is usually based on the infection and the prescriber’s instructions, often applied several times a day for a short course; there is no fixed maximum per day that fits every patient, so your doctor decides the schedule for this 5 g ointment.

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

Common side effects of Moxifloxacin may include:

• Temporary blurred vision after application
• Mild eye burning or stinging
• Eye irritation or discomfort
• Redness of the eye or eyelid
• Watery eyes
• Strange taste in the mouth after application

• Use only for bacterial eye infections diagnosed by a healthcare professional.
• Do not use 4Quin 5 g Ointment if you are allergic to moxifloxacin or other fluoroquinolone antibiotics.
• Do not touch the tube tip to your eye, fingers, or any surface to avoid contamination.
• Temporary blurred vision can make driving or using machinery unsafe right after dosing.
• Contact lenses should generally be avoided until the infection has cleared.
• Tell your doctor if you have a history of severe allergy to antibiotics or problems with your tendons.
• Use in pregnancy or breastfeeding should be reviewed by your prescriber, even though eye absorption is low.

• Other prescription eye drops or ointments, which may need spacing apart
• Warfarin or other blood thinners, if your clinician wants to monitor closely
• Systemic fluoroquinolone antibiotics, if you are using another one at the same time
• Any eye product containing preservatives that may irritate the eye when combined too closely

Store 4Quin 5 g Ointment at room temperature, tightly closed, and keep the tube clean and dry as directed on the package label.
