Uses

Quick Answer

Tobramycin Eye Drops (Tobrex) are used to treat bacterial conjunctivitis (red eye with purulent discharge), bacterial blepharitis (eyelid infection), and bacterial corneal ulcers. They are NOT effective for viral conjunctivitis, which is the most common cause of red eye. Always confirm diagnosis with your doctor before using antibiotic eye drops.

Primary Uses at a Glance

Bacterial Conjunctivitis

Tobramycin is effective for bacterial conjunctivitis — this is the red eye that has thick purulent (pus-like) discharge. Bacterial conjunctivitis typically starts in one eye and is highly contagious. Tobramycin is particularly useful against Gram-negative bacteria including Pseudomonas aeruginosa.

As prescribed by your doctor. Typically instil prescribed drops in affected eye multiple times daily. Complete the full course.

Bacterial Blepharitis

In bacterial blepharitis the eyelid margins become infected with bacteria — causing crusting, redness, and irritation. Tobramycin ophthalmic drops or ointment (Tobrex ointment) are both used. Combination with eyelid hygiene (warm compress) is effective.

As prescribed by your doctor. Use together with eyelid hygiene. Complete the full course.

Bacterial Corneal Ulcer / Keratitis

Bacterial keratitis (corneal ulcer) is a serious eye condition requiring immediate treatment — Pseudomonas aeruginosa is a common causative organism especially in contact lens wearers. Tobramycin is useful due to its Pseudomonas coverage, but ophthalmologist management is essential in severe cases.

As prescribed by ophthalmologist — URGENT. Specialist referral is necessary for corneal ulcer.

Confirm diagnosis with your doctor — antibiotic misuse increases resistance.

Post-operative eye surgery patients (as prescribed)

When NOT to Use (Kab nahi leni chahiye)
