Medicine overview

4Quin 0.5% Eye Ointment is an ophthalmic antibiotic containing moxifloxacin, a fluoroquinolone antibacterial medicine. The verified 5 g 4Quin ointment contains moxifloxacin 0.5% w/w; available product listings do not support ofloxacin as its active ingredient. It is applied to the eye for bacterial eye infections. Moxifloxacin works against susceptible bacteria by interfering with enzymes they need to copy and repair their DNA. The ointment is intended only for ophthalmic use.

What it is used for

4Quin Eye Ointment is used for bacterial infections of the eye caused by organisms susceptible to moxifloxacin. Moxifloxacin ophthalmic preparations are established antibacterial treatments for bacterial conjunctivitis. Antibiotics do not treat viral or fungal conjunctivitis, so persistent, worsening, or unexplained eye symptoms require medical assessment rather than prolonged or repeated antibiotic use.

How it works

Moxifloxacin is a fluoroquinolone antibiotic. It inhibits bacterial DNA gyrase and topoisomerase IV, enzymes involved in copying, repairing, and maintaining bacterial DNA. Blocking these processes prevents susceptible bacteria from reproducing normally and leads to bacterial cell death. When moxifloxacin is applied to an infected eye, this antibacterial activity helps control susceptible organisms at the site of infection.

How it is taken

Apply 4Quin only to the eye and use it exactly as prescribed. Wash your hands before application and avoid touching the tube tip to the eye, eyelid, fingers, or another surface, as this can contaminate the medicine. Do not create or change an application schedule without instructions from the prescriber. Contact lenses should not be worn when signs or symptoms of bacterial conjunctivitis are present.

Important warnings

Do not use moxifloxacin ophthalmic medicine if you have had a serious hypersensitivity reaction to moxifloxacin, another quinolone antibiotic, or an ingredient in the product. Serious allergic reactions have been reported with quinolone medicines; obtain urgent medical help for difficulty breathing, facial or throat swelling, widespread rash, or other signs of a severe reaction. Prolonged antibiotic use can encourage growth of non-susceptible organisms, including fungi. Seek medical assessment if the infection worsens, fails to improve as expected, or new symptoms develop. This product is for ophthalmic use and should not be injected into the eye.

Side effects and monitoring

Common effects of ophthalmic moxifloxacin can include temporary eye irritation, discomfort, pain, itching, dryness, redness, tearing, or blurred vision after application. Less common but important reactions include hypersensitivity and worsening or persistent eye inflammation. Stop using the medicine and obtain urgent medical care for signs of a severe allergic reaction. Significant eye pain, worsening redness, marked swelling, new visual changes, or deterioration despite treatment should be assessed promptly. Routine laboratory monitoring is not generally required for short-term topical ophthalmic use.

Pregnancy

Human pregnancy data for ophthalmic moxifloxacin are insufficient to establish a drug-associated risk. Systemic exposure after topical ocular administration is low, but use during pregnancy should be based on clinical need and professional assessment.

Breastfeeding

There are insufficient human data to determine whether moxifloxacin from ophthalmic use is present in breast milk or affects a breastfed infant. Systemic exposure after topical eye administration is low. The benefits of breastfeeding, the mother's clinical need for treatment, and any potential effects on the infant should be considered.

Food, drink and interactions

NOT VERIFIED

Food and drink

No food-related administration requirement is expected because this medicine is applied to the eye rather than swallowed.

Frequently asked questions

Why does my eye sting or feel irritated after using an antibiotic eye medicine?

Temporary local irritation can occur with ophthalmic antibiotics. Contact your prescriber promptly if irritation is severe, persists, or is accompanied by worsening pain, swelling, redness, or vision changes.

How soon should a bacterial eye infection start looking better?

Improvement depends on the infection and its severity. If symptoms worsen or fail to improve as expected during prescribed treatment, the eye should be reassessed rather than continuing or changing treatment without medical advice.

Can I wear contact lenses while using 4Quin for an eye infection?

Contact lenses should not be worn when you have signs or symptoms of bacterial conjunctivitis. Follow your eye-care professional's instructions about when it is safe to resume wearing them.

Can I stop the antibiotic when my eye starts feeling better?

Use 4Quin for the period prescribed rather than stopping or extending treatment on your own. Inadequate or unnecessarily prolonged antibiotic treatment can cause problems, so treatment duration should follow the prescriber's instructions.

What should I do if my eye becomes more painful or my vision gets worse?

Seek prompt medical assessment. Increasing pain, worsening inflammation, significant swelling, or new visual changes can indicate that the condition needs further evaluation.

Is 4Quin 5 g an ofloxacin eye ointment?

No, not according to the product information located for this exact presentation. The verified 4Quin 0.5% Eye Ointment 5 g is manufactured by Entod Pharmaceuticals Ltd and contains moxifloxacin 0.5% w/w; the supplied description of “Ofloxacin” does not match the identified product.

Can Cheap Generic Med ship 4Quin to the United States?

Cheap Generic Med serves the United States under its international shipping model. Delivery is typically estimated at 10–14 business days after dispatch, although customs or carrier delays can extend transit; prescription and import requirements may also apply.

Will my Cheap Generic Med order have tracking?

Tracked international shipping is used under the standard fulfilment model. A tracking number should be provided after dispatch, although carrier systems can take 24–72 hours to begin showing movement.
