Common use
Ciloxan is a trusted ophthalmic antibiotic prescribed to treat a wide range of bacterial eye infections, including bacterial conjunctivitis (commonly known as pink eye) and corneal ulcers. The active ingredient, ciprofloxacin, is a powerful fluoroquinolone antibiotic that works by inhibiting bacterial DNA gyrase and topoisomerase IV, effectively stopping bacteria from replicating and spreading. When you buy Ciloxan online, you get a clinically proven solution for eye infections that has been used by ophthalmologists worldwide. Ciprofloxacin eye drops are also sometimes prescribed off-label for bacterial ear infections such as otitis externa. As a broad-spectrum ophthalmic antibiotic, Ciloxan is effective against a variety of gram-positive and gram-negative organisms, making it a versatile first-line treatment for superficial ocular infections.

Dosage and direction
Apply the prescribed number of ciprofloxacin eye drops into the affected eye, usually 1–2 drops every 2–4 hours during the initial phase of treatment, then reduce frequency as the infection improves. For corneal ulcers, your doctor may recommend a more intensive dosing schedule during the first 48 hours. Use the drops at evenly spaced intervals throughout the day and complete the full course of treatment even if symptoms improve early. Always wash your hands before application and avoid touching the dropper tip to the eye or any other surface to prevent contamination. If you are using other eye drops, wait at least 5 minutes between applications to ensure proper absorption of each medication.

Precautions
Do not wear contact lenses while using Ciloxan for an eye infection, as lenses can harbor bacteria and interfere with the healing process. Inform your doctor if you have a history of allergic reactions to fluoroquinolone antibiotics, tendon disorders, or myasthenia gravis. Prolonged use of ciprofloxacin eye drops may lead to overgrowth of non-susceptible organisms, including fungi. If your eye infection does not improve within a few days or worsens, consult your healthcare provider promptly. Patients with a history of seizures should exercise caution, as systemic absorption of fluoroquinolones, though minimal with topical use, may lower the seizure threshold. Protect your eyes from excessive sunlight during treatment, as increased photosensitivity may occur.

Contraindications
Ciloxan should not be used by individuals who are allergic to ciprofloxacin, other fluoroquinolone antibiotics, or any inactive ingredients in the formulation. This ophthalmic antibiotic is specifically designed for bacterial infections and is not effective against viral eye infections (such as herpes simplex keratitis), fungal infections, or parasitic conditions of the eye. Do not use Ciloxan generic or branded versions without a confirmed bacterial diagnosis from your healthcare provider.

Possible side effect
Mild burning, stinging, or temporary discomfort may occur immediately after applying ciprofloxacin eye drops. Some patients report a white crystalline deposit on the corneal surface, particularly during intensive treatment for corneal ulcers — this typically resolves on its own. Other common side effects include itching, redness, tearing, and a foreign body sensation in the eye. Rare but serious side effects that require immediate medical attention include severe eye pain, significant swelling of the eyelids or face, vision changes, and signs of an allergic reaction such as rash, hives, or difficulty breathing. If you experience any persistent or worsening symptoms while using these eye drops, contact your doctor right away.

Drug interaction
While significant drug interactions with topical ciprofloxacin eye drops are uncommon due to limited systemic absorption, you should avoid combining Ciloxan with other ophthalmic medications unless specifically advised by your doctor. If multiple eye drops are prescribed, separate each application by at least 5–10 minutes. Inform your healthcare provider about all medications you are currently using, including prescription drugs, over-the-counter products, and supplements. Patients taking oral fluoroquinolones or systemic corticosteroids should mention this to their doctor before starting Ciloxan treatment.

Missed dose
Apply the missed dose of Ciloxan as soon as you remember. If it is almost time for your next scheduled dose, skip the missed one and continue with your regular dosing schedule. Do not apply a double dose to make up for a missed application, as this will not speed recovery and may increase the risk of side effects.

Overdose
Excessive use of ciprofloxacin eye drops may lead to increased local irritation, punctate keratitis, or development of drug-resistant bacteria. If Ciloxan is accidentally swallowed, contact a healthcare provider or poison control center immediately, although serious toxicity from topical ophthalmic preparations is unlikely.

Storage
Store Ciloxan at room temperature between 15–25°C (59–77°F), away from direct light and moisture. Keep the bottle tightly closed when not in use and discard any remaining solution after the expiration date or as directed by your pharmacist. Keep all medications out of reach of children and pets.
