Tobracid 0.3% Eye Ointment

Tobracid 0.3% Eye Ointment is a prescription antibiotic eye medicine that contains tobramycin 0.3% in each tube. It belongs to the aminoglycoside class of antibiotics and is used to treat certain bacterial eye infections. Tobracid 0.3% Eye Ointment is applied to the eye area, where it helps stop susceptible bacteria from growing and spreading. It is for bacterial infections only and will not treat viral or fungal eye problems.

How it works: Tobramycin works by entering susceptible bacteria and blocking their ability to make the proteins they need to survive. In ointment form, Tobracid 0.3% Eye Ointment coats the eye surface and can stay on longer than drops, which may help it keep working between doses.

Tobracid 0.3% Eye Ointment is the standard ophthalmic ointment strength for tobramycin, so it is not a higher-dose version compared with other Tobramycin eye products. The ointment form is often chosen when longer contact time on the eye is helpful, such as overnight use or when an ointment feel is preferred over drops. A doctor may choose Tobracid 0.3% Eye Ointment when they want antibiotic coverage with a thicker formulation that stays in place longer.

• Bacterial conjunctivitis
• Blepharitis caused by susceptible bacteria
• Bacterial keratitis
• Eye infection treatment as prescribed by a doctor
• Post-procedure eye infection prevention when directed

• Wash your hands before and after using Tobracid 0.3% Eye Ointment.
• Pull down the lower eyelid and apply a thin ribbon of ointment into the lower eyelid pocket.
• Do not let the tube tip touch your eye, fingers, or any surface.
• After applying, close the eye gently for 1 to 2 minutes; vision may be blurred for a short time.
• If you wear contact lenses, remove them before use and do not put them back in until your doctor says it is okay.
• Use it exactly as often as prescribed; ointments are commonly used several times a day and sometimes at bedtime.

Each tube of Tobracid 0.3% Eye Ointment contains tobramycin 0.3%. The exact dose and how many times per day you use it depend on the infection and your doctor’s instructions; some patients use it several times daily, while others may use it less often as symptoms improve. There is no single maximum daily dose for all patients, because the prescriber decides the regimen for this specific eye ointment.

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

Common side effects of Tobramycin may include:

• Temporary blurred vision after application
• Eye burning or stinging
• Mild eye irritation
• Eye redness
• Itchy eyes
• Watery eyes
• Sticky or greasy feeling in the eye

• Use only in the eye, not in the ear or by mouth.
• Do not use if you are allergic to tobramycin or other aminoglycoside antibiotics unless your doctor says it is safe.
• Do not wear contact lenses during an active eye infection unless your eye doctor specifically allows it.
• Blurred vision after dosing can make driving or using machinery unsafe until your vision clears.
• Tell your doctor if you are pregnant, breastfeeding, or have a history of kidney, hearing, or nerve problems.
• Use Tobracid 0.3% Eye Ointment for the full prescribed course, even if symptoms start to improve.
• If you use other eye medicines, separate them as directed so the ointment does not block absorption of other drops.

• Other eye medicines, including drops or ointments, may need to be spaced apart.
• Other aminoglycoside antibiotics may increase the risk of allergic reaction or additive toxicity.
• Loop diuretics such as furosemide may raise concern for aminoglycoside-related toxicity if absorbed systemically, especially with frequent use.
• Neuromuscular blockers may interact with aminoglycosides in rare cases, especially in medically complex patients.

Store Tobracid 0.3% Eye Ointment at room temperature, keep the tube tightly closed, and protect it from contamination by not touching the tip to any surface.
