TobraDex (tobramycin / dexamethasone) is available as eye drops and an eye ointment. It's used to treat and relieve bacterial eye infections. This medication contains tobramycin (an aminoglycoside antibiotic that helps fight the infection) and dexamethasone (a corticosteroid that helps lower eye inflammation). Most people have few to no side effects from the medication when they use it as directed. But the medication can raise your eye pressure if you use it for more than 10 days.
Eye inflammation from a bacterial infection in the eye
Eye inflammation when there's a risk for a bacterial infection in the eye
TobraDex (tobramycin / dexamethasone) is a combination of two medications.
Tobramycin is an aminoglycoside antibiotic. It kills bacteria by preventing them from making proteins that they need to survive.
Dexamethasone is a corticosteroid. When it’s used in the eye, it lowers the amount of chemicals that cause pain, redness, and swelling there. This helps lower eye inflammation and relieve eye pain.

Use TobraDex (tobramycin / dexamethasone) as directed by your prescriber. Don't stop using it before you complete treatment, even if your eye starts to get better. Your infection might come back or become harder to treat if you stop using the medication too early.
Talk with your primary care provider if your eye inflammation or eye infection gets worse after you start using TobraDex (tobramycin / dexamethasone). You might need to get your eye checked out to see whether the medication is the most appropriate for your infection.
Don't let the tip of the bottle or tube touch the eye, eyelid, or other surfaces. Don't touch the tip with your fingers. Otherwise, the medication can get contaminated. Using contaminated medication in the eye can cause serious harm, such as eye infection or vision loss.
TobraDex (tobramycin / dexamethasone) can temporarily blur your vision. Don't drive a car or operate machinery until you know how this medication affects your vision and until you can see clearly.
Remove any contact lenses from your eyes before each time you use TobraDex (tobramycin / dexamethasone). Some formulations of the medication contain a preservative called benzalkonium chloride. This preservative can get absorbed by soft contact lenses, which might affect how well the lenses work, fit, or feel on the eyes.
In general, it's best not to wear contact lenses when you have an eye infection so that your infection doesn't get worse or your eye doesn't get even more irritated. Make sure to throw away the contact lenses you were wearing before you started using TobraDex (tobramycin / dexamethasone); they most likely have bacteria on them.
Wash your hands with soap and water before and after each time you use TobraDex (tobramycin / dexamethasone). Discuss with your primary care provider or with your care team about other ways to help prevent your eye infection from getting worse and any new eye infections from popping up.
How to use TobraDex (tobramycin / dexamethasone) eye drops:
Shake the bottle well before using. This makes sure the medication hasn’t settled at the bottom of the bottle.
To use the eye drops, pull down your lower eyelid with one hand. Hold the bottle upside down just above the eye with the other hand. Gently squeeze the bottle to get the number of drops you need in your eye. Then, close your eye and press your finger to the corner of your eye closest to your nose for a minute. This helps the medication stay in your eye and prevents it from leaking into the nose.
If you need to use another eye drop in the same eye, wait a few minutes so the second eye drop doesn't rinse off the first one.
How to use TobraDex (tobramycin / dexamethasone) eye ointment:
Pull down your lower eyelid with one hand, and hold the tube of ointment with the other.
Place a small amount (about one-half of an inch) of ointment in the space between your lower eyelid and eyeball. Briefly look down before you close your eye for a few minutes to help the medication reach all the necessary parts of the eye.
TobraDex (tobramycin / dexamethasone) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Use TobraDex (tobramycin / dexamethasone) on the surface of the eye only. Don't put TobraDex (tobramycin / dexamethasone) in your mouth, nose, or other parts of your body. Also don't use the medication as an injection into any parts of the eye.
Risk factors: Using TobraDex (tobramycin / dexamethasone) for more than 10 days | History of glaucoma
Using eye medications containing steroids long term can cause your eye pressure to go up. This can damage the eye and cause vision problems. Talk with your prescriber about the risks and benefits of using TobraDex (tobramycin / dexamethasone) if you already have glaucoma or high eye pressure.
Your prescriber might recommend that you go to your optometrist's office for an eye exam to check your eye pressure and make sure that TobraDex (tobramycin / dexamethasone) is safe for you. Your prescriber is more likely to suggest an eye exam if you need to use this medication for more than 10 days.
People don't typically have noticeable symptoms when their eye pressure is high, but some might feel pain when they move their eye around or when they touch the eye. Talk with your primary care provider or optometrist right away if you have eye pain or any vision problems while you're using TobraDex (tobramycin / dexamethasone).
Risk factors: Using TobraDex (tobramycin / dexamethasone) for more than 10 days
Using TobraDex (tobramycin / dexamethasone) long term can raise the risk of developing other eye infections, such as fungal or bacterial eye infections. Don't use TobraDex (tobramycin / dexamethasone) if you have a viral eye infection because it can make your infection worse. Contact your primary care provider or urgent care if you have eye pain or redness, blurry vision, sensitivity to bright light, or watery discharge from your eye. Also call them if your symptoms don't improve after a couple days of treatment. These can be signs of a new eye infection that needs to be examined.
Risk factors: History of cataract | Using TobraDex (tobramycin / dexamethasone) for more than 10 days
In certain cases, using TobraDex (tobramycin / dexamethasone) might cause your cornea (the clear, outer layer of the eye) or the "whites" of the eye to thin. Sometimes, this can lead to eye damage. In addition, using TobraDex (tobramycin / dexamethasone) for a long period of time can cause cataracts (clouding of eye lens) to form. Seek medical attention right away if you have vision loss, blurry vision, or eye pain or if your eye is more watery than usual.
Using TobraDex (tobramycin / dexamethasone) after a cataract surgery might also slow down the healing process and raise the risk of fluid buildup in the eye. Talk with your eye surgeon right away if you’ve just had cataract surgery and you're having eye or vision problems.
Before you're prescribed TobraDex (tobramycin / dexamethasone), tell your primary care provider or a member of the urgent care team if you've had an allergy to similar antibiotics, such as gentamicin (Gentak). It's possible that you could have an allergic reaction to TobraDex (tobramycin / dexamethasone), too.
In general, watch out for signs and symptoms of allergic reactions, such as swollen eyelids, red or itchy eyes, or skin rash. Stop using TobraDex (tobramycin / dexamethasone) and call your primary care provider if you have an allergic reaction. These reactions often go away on their own once you stop the medication.
You might also be allergic to TobraDex (tobramycin / dexamethasone) if your eye infection doesn't get better after you start using the medication. Contact your primary care provider if your eye infection doesn't improve after a couple days of using the medication.
