Zuflo Eye Drop with ofloxacin

Zuflo Eye/Ear Drops is a sterile ophthalmic and otic solution available in a 10 ml bottle. Each ml of the solution contains Ofloxacin 0.3% w/v as the active ingredient, along with a preservative and sterile aqueous vehicle. The product is strictly for external ophthalmic and otic use only and must not be injected or ingested. It is a broad-spectrum fluoroquinolone antibiotic used for the treatment of bacterial eye and ear infections. The product is packaged in a clean white box with a light green lower section, featuring a small stylized graphic of an eye with a red and orange iris centered between the two color blocks, with the brand name “ZUFLO” displayed prominently in bold black capital letters.

Ofloxacin is a broad-spectrum fluoroquinolone antibiotic that works by inhibiting two key bacterial enzymes, DNA gyrase (topoisomerase II) and topoisomerase IV. These enzymes are essential for bacterial DNA replication, transcription, and recombination. By blocking their activity, ofloxacin prevents the bacteria from replicating their genetic material and from repairing damaged DNA, effectively stopping bacterial growth and leading to cell death. This dual-target mechanism gives ofloxacin a very broad spectrum of activity against both gram-positive and gram-negative bacteria, including common eye and ear pathogens such as Staphylococcus aureus, Streptococcus pneumoniae, Haemophilus influenzae, Pseudomonas aeruginosa, Escherichia coli, and Moraxella catarrhalis. The drug achieves good penetration into the cornea, aqueous humor, and middle ear fluid, making it effective for both ocular and otic infections.

The primary indications for Zuflo Eye/Ear Drops are the treatment of bacterial eye infections including bacterial conjunctivitis (pink eye), corneal ulcers (keratitis), and other superficial ocular infections. For ear infections, it is indicated for the treatment of acute otitis externa (outer ear infection, commonly known as swimmer’s ear) and other bacterial infections of the external ear canal. The product is effective in reducing redness, swelling, discharge, pain, and irritation associated with these conditions. It is not effective against viral or fungal infections and should not be used for these conditions. The product is intended for use in adults and children, though it should be used under medical supervision in pediatric patients.

The recommended dosage for eye infections is 1 to 2 drops instilled into the affected eye every 2 hours for the first 2 days, followed by 1 to 2 drops every 4 hours for the next 2 to 3 days, or as directed by the ophthalmologist. For ear infections, 2 to 3 drops are instilled into the affected ear 2 to 3 times daily. It is essential to complete the full course of treatment even if symptoms improve before the course is finished, to prevent the development of antibiotic-resistant bacteria and recurrence of infection. Stopping the medicine too early may lead to the infection returning or worsening. The product should only be used under the supervision of a qualified ophthalmologist or otolaryngologist.

The most common side effects include mild burning or stinging sensation in the eye or ear immediately after application, eye discomfort, eye irritation, temporary blurred vision, dryness, and a change in taste (dysgeusia) due to the solution draining through the nasolacrimal duct. Other common side effects include eye redness, itching, increased tearing, foreign body sensation, and mild headache. These effects are generally mild and transient, resolving within a few minutes to a few hours. Uncommon side effects may include dizziness, nausea, and photosensitivity.

Serious but rare side effects include severe hypersensitivity reactions (rash, hives, swelling of face/lips/tongue, difficulty breathing), which have been reported with fluoroquinolones and can occasionally occur even after the first dose. Prolonged or inappropriate use may result in overgrowth of non-susceptible organisms, including fungi, leading to new or worsening infections. Other rare but serious effects include tendonitis or tendon rupture, hearing changes, and increased intraocular pressure. Patients should seek immediate medical attention if they experience severe eye or ear pain, sudden vision changes, persistent redness or swelling, hearing loss, or signs of a severe allergic reaction.

Important precautions include not wearing contact lenses during treatment, as the infection itself and the preservative in the drops can both damage the lenses. If using other eye or ear medications simultaneously, a gap of at least 5 to 10 minutes should be maintained between different drops. Patients should avoid driving or operating heavy machinery until their vision is clear after application, as temporary blurred vision and dizziness are possible. The product should not be used in patients with a known hypersensitivity to ofloxacin or other fluoroquinolones. It should not be used if there is a perforated eardrum for ear application, as it could enter the middle ear and cause side effects. The product is not recommended during pregnancy as animal studies have shown adverse effects on the fetus, though there are limited human data. It may pass into breast milk, so use during breastfeeding should only be under medical supervision. The dropper tip should not be touched to the eye, ear, or any surface to maintain sterility. The product should not be used if the solution changes color or becomes cloudy.

The product should be stored below 30 degrees Celsius in a cool and dry place away from direct sunlight and kept out of reach of children. The bottle should be tightly closed after each use. The product is available in India at a price of approximately 27 to 57 rupees per 10 ml bottle and is available through major online pharmacy platforms and offline pharmacies with a valid prescription.
