Levofloxacin is a fluoroquinolone antibiotic used to treat bacterial infections of the eye.

- Bacterial conjunctivitis: reduces bacterial load and resolves redness, discharge and irritation. - Keratitis: eradicates causative bacteria and promotes corneal healing. - Other bacterial eye infections: treats infections such as blepharitis or corneal ulceration caused by susceptible organisms.

Levofloxacin may cause ocular and systemic adverse reactions.

Common Side Effects: - Eye irritation or burning on instillation. - Redness of the conjunctiva. - Temporary blurred vision. - Tearing or excessive lacrimation. - Mild headache. - Nausea (rare with ocular use).

Serious or Rare Side Effects: - Severe allergic reaction (anaphylaxis, angioedema). - Tendon rupture or tendonitis, especially in patients with systemic exposure. - Stevens‑Johnson syndrome or toxic epidermal necrolysis. - Corneal ulceration or perforation. - Vision loss due to optic neuritis. - Systemic QT prolongation in susceptible individuals.

Before using Levonic-Opto, consider the following precautions.

- Pregnancy: safety not established; avoid unless benefits outweigh risks. - Breastfeeding: unknown excretion; consider potential risk to infant. - Renal impairment: dose adjustment may be required based on prescriber assessment. - Hypersensitivity: discontinue immediately if allergic reaction occurs. - Contact lens wearers: avoid use while wearing lenses; remove lenses before instillation. - Store at room temperature: keep in original container, protect from light and moisture.

Levofloxacin can interact with other medicines; monitor accordingly.

Major Interactions (Avoid): - Systemic fluoroquinolones: concurrent use may increase risk of tendon rupture. - Antacids containing aluminum or magnesium: may reduce ocular absorption. - Corticosteroids: may increase risk of secondary ocular infections.

Moderate Interactions (Monitor Closely): - Warfarin: levofloxacin may enhance anticoagulant effect, requiring INR monitoring. - Theophylline: may increase plasma theophylline concentrations. - NSAIDs (topical): may raise risk of corneal toxicity when used together.
