Tobastar 5 mL Eye Drop

Tobastar 5 mL Eye Drop is an ophthalmic antibiotic containing tobramycin, an aminoglycoside used to treat certain bacterial eye infections. Each drop delivers tobramycin in a 5 mL eye drop solution format, making it a liquid medicine you place directly into the eye. Tobastar 5 mL Eye Drop works against susceptible bacteria and is commonly prescribed for bacterial conjunctivitis and other superficial eye infections. It does not treat viral or allergic eye problems.

How it works: Tobramycin stops bacteria from making the proteins they need to grow and survive. When used as Tobastar 5 mL Eye Drop, it acts right on the eye surface to help clear the infection where it is present.

Tobastar 5 mL Eye Drop is the standard eye-drop size for tobramycin treatment, so it fits routine short-course dosing when a doctor wants a topical antibiotic that can be applied directly to the eye. Because it is a liquid ophthalmic solution, it can be started and adjusted by the prescriber based on infection severity, unlike oral antibiotics or non-ophthalmic forms.

• Bacterial conjunctivitis
• Superficial bacterial eye infections
• Treatment of susceptible bacteria in the eye
• Doctor-directed prevention of worsening eye infection after exam or injury

• Wash your hands before using Tobastar 5 mL Eye Drop.
• Tilt your head back, pull down the lower eyelid, and place the prescribed number of drops into the eye.
• Avoid touching the dropper tip to your eye, fingers, or any surface.
• After putting in the drop, close your eye gently and press the inner corner for 1 minute if your doctor has shown you how.
• If you use other eye medicines, wait at least 5 to 10 minutes between products unless your doctor gives different instructions.
• Do not wear contact lenses during an active eye infection unless your eye doctor says it is okay.

Tobastar 5 mL Eye Drop supplies tobramycin in a 5 mL ophthalmic bottle; the exact number of drops per dose depends on the doctor’s prescription and the severity of the infection. It is often used several times a day, but the frequency and total daily amount are decided by the prescriber for this strength. Do not use more often than prescribed, because the doctor determines the correct schedule for Tobastar 5 mL Eye Drop.

Do not change your dose or stop the medicine without speaking to your doctor.
