Bacterial eye infections such as conjunctivitis (commonly known as pink eye) and blepharitis often cause symptoms like redness, itching, pain, and discharge that can make the eyes uncomfortable and affect vision. Selecting the right eye drops for bacterial infection is crucial to effectively eliminate the bacteria, reduce symptoms, and speed recovery. This comprehensive guide covers top prescription antibiotics, the role of over-the-counter (OTC) eye drops, proper usage, and recommendations from us at Zexus Pharmaceuticals, India’s leading eye care manufacturer.
Prescription antibiotic eye drops are the frontline treatment for bacterial eye infections because they directly kill the bacteria causing the infection. Here are some of the widely used and trusted antibiotic eye drops in India:
Moxifloxacin (Vigamox): This broad-spectrum fluoroquinolone antibiotic is highly effective against many common bacteria causing conjunctivitis and other eye infections. It is fast-acting and usually well-tolerated, suitable for both adults and children above four months of age. Moxifloxacin penetrates eye tissues well and helps prevent infection complications.
Tobramycin: Tobramycin eye drops are often prescribed for tougher bacterial infections, including those affecting the eyelids (blepharitis). They are safe for children and work by inhibiting bacterial protein synthesis. Tobramycin eye drops are effective against Pseudomonas and other gram-negative bacteria, which can sometimes be resistant to other antibiotics.
Ofloxacin: This fluoroquinolone antibiotic is effective against a wide range of bacteria and is particularly used for eye surface infections like bacterial conjunctivitis and corneal ulcers. Ofloxacin works rapidly to reduce bacterial growth and relieve symptoms.
Chloramphenicol: In some countries including India, chloramphenicol eye drops remain a popular treatment for bacterial conjunctivitis due to their broad effectiveness. They are usually dosed several times a day and have a long history of use.
Erythromycin Ointment: This antibiotic ointment is frequently used in newborns to prevent eye infections and in patients with sensitive eyes where liquid drops might cause irritation. It provides a protective coating on the eye surface alongside antibiotic benefit.

While OTC eye drops like artificial tears and lubricating drops do not kill bacteria themselves, they can relieve itching, dryness, and irritation caused by infections. They are best used as a complement to prescription antibiotics, helping soothe the eyes during the healing process. However, OTC drops should never replace antibiotic eye drops when an infection is suspected. If symptoms persist or worsen, it is essential to seek professional treatment promptly.

Are antibiotic eye drops safe for all ages?
Yes, but only when prescribed by a healthcare professional. Infants and children may require specific formulations or dosages adjusted for their age and sensitivity. Always consult a doctor before administering antibiotic eye drops to children.
How long does it take for eye drops to work?
Symptoms often start improving within 1 to 2 days of starting treatment, but it is important to complete the full prescribed course (usually 5 to 7 days) to avoid recurrence or resistance.
Can I use leftover antibiotic eye drops from a previous infection?
No, never reuse old or expired antibiotic eye drops without consulting a healthcare provider. Using leftovers can be ineffective or unsafe.
What are the signs of a bacterial eye infection?
Typical signs include redness, thick yellow or green discharge, irritation, eyelids stuck together especially after sleep, and sometimes pain and swelling.
Is it contagious?
Yes, many bacterial eye infections are highly contagious and spread easily through contact. Avoid touching your eyes and wash hands frequently to prevent transmission.
Can I wear contact lenses during treatment?
No, it is best to avoid contact lens use until the infection is fully cleared and your doctor confirms it is safe to resume.

Choosing and using the right eye drops for bacterial infection is essential for rapid healing and preventing complications such as spread or chronic infection. Prescription antibiotic drops remain the most effective treatment for eradicating bacteria, while supportive OTC products can alleviate symptoms during recovery. Proper hygiene, correct application, and adherence to medical advice are vital for success.
