About Gatifloxacin
Indications of Gatifloxacin
Gatifloxacin ophthalmic solution is a fluoroquinolone antibiotic eye drop used for the topical treatment of bacterial infections of the eye.
Established / FDA-Approved Use
- Treatment of bacterial conjunctivitis caused by susceptible strains of gram-positive organisms (e.g., Staphylococcus aureus, Staphylococcus epidermidis, Streptococcus pneumoniae, Streptococcus viridans group) and gram-negative organisms (e.g., Haemophilus influenzae, Pseudomonas aeruginosa).
Off-Label / Other Uses (physician discretion only)
- Peri-operative prophylaxis against ocular infection before or after eye surgery, used off-label by some ophthalmologists.
- Other external ocular infections (e.g., select cases of bacterial keratitis) under specialist supervision; not a first-line, formally approved indication.
Note: In Bangladesh, Gatifloxacin is marketed only as an ophthalmic (eye drop) preparation. Oral/systemic forms of Gatifloxacin are not available here and have been withdrawn or restricted in several countries due to safety concerns (see Precautions and Warnings).

Side Effects of Gatifloxacin
The most common side effects of Gatifloxacin eye drops are local and generally mild:

Frequently Asked Questions about Gatifloxacin
What is Gatifloxacin eye drop used for?
Gatifloxacin eye drops are used to treat bacterial conjunctivitis (a bacterial eye infection, sometimes called "pink eye") caused by susceptible bacteria. It is applied directly to the affected eye and is not effective against viral or allergic conjunctivitis.
How long should I use Gatifloxacin eye drops?
Treatment usually lasts 7 days. For the 0.3% solution, use 1 drop every 2 hours (up to 8 times a day) for the first 1–2 days, then 1 drop up to 4 times daily through day 7; for the 0.5% solution, use 1 drop every 2 hours (up to 8 times a day) on day 1, then 1 drop 2–4 times daily on days 2–7. Always complete the full course exactly as prescribed by your physician, and do not stop, extend, skip doses, or share Gatifloxacin with others without medical advice, even if your eye feels better sooner.
Can I wear contact lenses while using Gatifloxacin eye drops?
No. Contact lenses should not be worn while you have signs or symptoms of bacterial conjunctivitis being treated with Gatifloxacin. Ask your physician when it is safe to resume wearing contact lenses.
Is Gatifloxacin eye drop safe during pregnancy or breastfeeding?
Gatifloxacin ophthalmic solution should be used during pregnancy only if clearly needed and the potential benefit justifies the potential risk to the fetus, since systemic fluoroquinolones have been linked to joint/cartilage effects in animal studies, even though absorption from eye drops is minimal. It is also not established whether topical Gatifloxacin passes into breast milk in significant amounts. In both situations, consult a physician before use.
What are the common side effects of Gatifloxacin eye drops?
The most common effects are local and mild, including conjunctival irritation, increased tearing, eye discomfort, blurred vision, an unpleasant taste after instillation, and itching. Less commonly, keratitis, reduced visual acuity, or allergic reactions can occur. Contact your physician if symptoms worsen or if you develop a rash, severe eye pain, or vision changes.
What should I do if Gatifloxacin eye drops are accidentally swallowed?
Accidental ingestion of a small amount of Gatifloxacin eye drop solution is unlikely to cause serious systemic toxicity, but you should contact a physician, hospital emergency department, or poison control center immediately, or seek urgent medical attention, rather than attempting home treatment.
