    How To Use Tobramycin Ophthalmic

    To apply eye drops, wash your hands first. To avoid contamination, do not touch the dropper tip or let it touch your eye or any other surface.

    Do not wear contact lenses while you are using this medicine. Sterilize contact lenses according to manufacturer’s directions and check with your doctor before using them.

    Tilt your head back, look upward and pull down the lower eyelid to make a pouch. Hold the dropper directly over your eye and place one drop into the pouch. Look downward and gently close your eyes for 1 to 2 minutes. Place one finger at the corner of your eye and apply gentle pressure. This will prevent the medication from draining out. Try not to blink and do not rub your eye. Repeat these steps for your other eye if so directed, and if your dose is for more than 1 drop.

    Do not rinse the dropper. Replace the dropper cap after each use.

    If you are using another kind of eye medication , wait at least 5 to 10 minutes before applying other medications. Use eye drops before eye ointments to allow the eye drops to enter the eye.

    Use this medication regularly in order to get the most benefit from it. Remember to use it at the same times each day. Continue to use this medication for the full time prescribed even if symptoms disappear after a few days. Stopping the medication too early may allow bacteria to continue to grow, which may result in a relapse of the infection.

    Inform your doctor if your condition persists or worsens.

    Treatment Of Corneal Ulcers

    The goals of treatment of corneal ulcers are to:

    • Prevent/treat infection
    • Prevent/stop progression through the corneal stroma
    • Prevent/treat pain
    • Provide structural support or facilitate healing when necessary

    For a simple ulcer with no apparent underlying cause, treatment with a topical antibiotic three to four times daily may be all that is needed. Most owners find it easier to apply drops than ointments, so I typically prescribe/dispense antibiotic solution unless there is a specific condition that is an indication for use of ointments . A topical aminoglycoside or triple antibiotic combination are good choices. For pain relief, if a dog is only minimally painful, I may apply one dose of topical atropine in the exam room. This will last for a few days in a dog, and this should be sufficient for an ulcer that one expects to heal. If the ulcer is more painful, supplement with your choice of oral pain relievers, an NSAID and/or tramadol and/or gabapentin.

    Certainly, if you find an underlying cause such as an aberrant hair or entropion, address this, in conjunction with your ophthalmologist if needed.

    Recommend that the owner makes a recheck within a week, and prior to that time if the pet is painful, as judged by blepharospasm.

    About Tobramycin For Eye Infections

    Type of medicine
    Available as Eye drops

    Tobramycin eye drops are prescribed to treat bacterial eye infections. They work by helping to kill the germs which are causing the infection.

    Eye infections are a common cause of conjunctivitis. In conjunctivitis, your eye becomes inflamed, feels gritty, and may water more than usual. The white of your eye may look red, and your eyelids may become swollen and stuck together with a discharge when you wake up in the morning. Only one eye may be infected to begin with, but it often spreads to both eyes. Although infective conjunctivitis may clear without treatment, for more severe infections or for infections which do not clear on their own, antibiotic eye drops like tobramycin are helpful.

    Tobramycin is also available combined with a medicine called dexamethasone in eye drops called Tobradex®. This combination brand helps to prevent infection and reduces inflammation after eye cataract surgery.

    Is It Indolent Or Infected

    If an ulcer is indolent , it will not heal on its own. This condition only occurs in middle-aged to older dogs. An indolent ulcer is superficial and has loose epithelial margins. The pathogenesis of this condition is that the superficial corneal stroma becomes unhealthy and unable to maintain attachments to the overlying corneal epithelium. The hallmark is the presence of loose epithelial margins at the edge of the ulcer. Indolent ulcers are common I see several of these every week, so your index of suspicion for this condition should be high in an older dog.

    An infected ulcer is a serious condition that can become a descemetocele or perforation in only a day or two. Most pets with corneal ulcers with secondary bacterial infections will exhibit considerable pain . Upon close inspection, the area of the stroma surrounding the ulcer may be opaque with a white to tan infiltrate. Corneal ulceration causes a reflex uveitis which can be severe in cases of secondary infection. Signs include miosis relative to the fellow eye, aqueous flare, and hypopyon. The presence of hypopyon in an eye with a corneal ulcer typically indicates an infection on the corneal surface, not inside the eye. In contrast, bacterial endophthalmitis is very rare in small animals.

    How Does Tobrex Eye Drops Work

    Tobrex Eye Drops 0.3% contain tobramycin, an antibiotic belonging to the aminoglycosides group of antibiotics. Tobramycin in Tobrex Eye Drops is a broad spectrum antibiotic that works by binding to bacterial ribosomes and blocking the translation of RNA into important proteins, which ultimately kills the bacteria. Tobramycin in Tobrex Eye Drops is effective against Staphylococci aureus and Streptococcus pneumoniae, which are the most predominant bacterial species to infect the eye and are normally found around the eye but can cause infection if they penetrate the eye or if the immune system is not effective. Other susceptible bacteria that can cause eye infection include Haemophilus and Moraxella. Tobrex Eye Drops are for topical use only and exert their bactericidal effects locally in the eye, with little systemic action.

    Dosing Information Of Tobramycin For Dogs And Cats

    What About That New Miracle Drop

    There are several commercially-available preparations that have been marketed to facilitate healing of corneal ulcers. At this point, there is no credible evidence that any of these preparations is more useful than any other artificial tears. So, is it worth recommending these medications for treatment of ulcers? These are not likely to cause any harm, with the caveat that owners will not always administer all medications as directed. If owners are having difficulty administering medications, they may skip some doses, and they often do not know which medications are the most important so may skip them, instead going with the medication with the coolest label.

    What Should I Do In Case Of Emergency

    When used as an eye medication, overdoses are unlikely. If your pet eats the medication, toxic effects could occur. If you suspect an overdose or an adverse reaction to the medication, call your veterinary office immediately. If they are not available, follow their directions in contacting an emergency facility.
