Introduction
As a topical quinolone antibacterial agent, levofloxacin eye drops are primarily used to combat ocular bacterial infections, treat bacterial conjunctivitis, relieve symptoms of blepharitis, manage corneal infections, and prevent postoperative eye infections. Hands should be cleaned before use, and the dropper tip should not touch the eye to avoid contamination. The product is contraindicated in individuals with known hypersensitivity to quinolones. It is recommended to use the solution within the specified time after opening.
As a topical quinolone antibacterial agent, levofloxacin eye drops are primarily effective in fighting ocular bacteria, treating bacterial conjunctivitis, relieving symptoms of blepharitis, managing corneal infections, and preventing postoperative eye infections. Detailed explanations are as follows:
1. Anti-bacterial action: The medication exerts a strong inhibitory effect against common ocular pathogens such as Staphylococcus and Streptococcus species. By interfering with bacterial DNA replication, it suppresses bacterial activity and controls infection at its source.
2. Treatment of bacterial conjunctivitis: It is highly effective against conjunctivitis caused by bacterial infections, helping to reduce excessive eye discharge, conjunctival congestion, and itching, while promoting resolution of the inflammation.
3. Relief of blepharitis symptoms: It can be used to treat blepharitis resulting from bacterial infection, improving symptoms such as eyelid redness, swelling, pain, and increased scaling, and preventing the spread of inflammation that could lead to more severe eye discomfort.
4. Management of corneal infections: Suitable for keratitis caused by susceptible bacteria, the drug can penetrate into corneal tissue to inhibit bacterial proliferation, alleviate symptoms such as corneal edema, photophobia, and tearing, and help preserve corneal function.
5. Prevention of postoperative eye infections: When used before and after eye surgeries such as cataract or glaucoma surgery, it effectively reduces the risk of postoperative bacterial infections, provides a clean environment for ocular tissue healing, and supports recovery.
Before use, wash hands thoroughly. Avoid contact between the dropper tip and the eye to prevent contamination. Do not use if allergic to quinolone antibiotics. After opening, use within the recommended time frame to avoid medication contamination.
