Tobramycin+dexamethasone
About Tobramycin+dexamethasone
Dexamethasone+tobramycin is a combination of antibiotics and corticosteroids used to treat bacterial eye and ear infections. It is used to treat eye infections such as conjunctivitis (infection of the outer white membrane of the eyeball) and corneal ulcers (ulcer that occurs in the transplant membrane of the eye called the cornea). This infection is highly contagious in nature and can pass from one to another. Signs and symptoms include pink/red-toned eyes, gritty feeling in eyes, itchiness in areas of eyes, teary eyes, and thick discharge around eyes.
Dexamethasone+tobramycin contains Tobramycin and Dexamethasone. Tobramycin is an aminoglycoside which inhibits the growth of bacteria by interfering with protein synthesis and leads to cell death. Dexamethasone is a corticosteroid medicine that reduces swelling and redness by preventing infection-fighting white blood cells (WBCs)
Dexamethasone+tobramycin is an external preparation and should be administered as advised by your doctor. Dexamethasone+tobramycin should be taken in the dose and duration your doctor advises. You are advised to take Dexamethasone+tobramycin for as long as your doctor has prescribed it for you, depending on your medical condition. Dexamethasone+tobramycin can cause some common side effects (when eye drops are used), including redness, itching, swelling, burning sensation, tearing, and temporary blurred vision (with ointment use). Most of these side effects of Dexamethasone+tobramycin do not require medical attention and gradually resolve over time. However, if the side effects are persistent, reach out to your doctor. Long-term use of eye drops may cause a fungal eye infection. So, take this medicine for a duration prescribed by your doctor.
Dexamethasone+tobramycin should be avoided if you are allergic to it, other aminoglycoside antibiotics or other ingredients. Inform your doctor if you are on any topical nonsteroidal anti-inflammatory drugs (NSAIDs), as Dexamethasone+tobramycin combined with topical NSAIDs may cause your eye wound to heal more slowly. Avoid wearing contact lenses during the treatment of ocular infection or inflammation, as it can worsen the condition. Tell your doctor about all your current medications and medical history before using Dexamethasone+tobramycin. Inform your doctor if you have any vision problems after using this medication. Tell your doctor if you are pregnant or breastfeeding. Dexamethasone+tobramycin is not recommended for use in children below two years of age.
Uses of Tobramycin+dexamethasone
Medicinal Benefits
Dexamethasone+tobramycin is a combination of two drugs: Tobramycin (antibiotics) and Dexamethasone (corticosteroids). Tobramycin works by inhibiting the growth of bacteria. Dexamethasone blocks the chemical messenger in the brain responsible for causing inflammation (redness, itching, and swelling). As a result, it lowers inflammation, which could worsen the condition. Dexamethasone+tobramycin is used to prevent and treat inflammation and prevent possible bacterial infection of the eye after cataract surgery in adults and children above two years of age.

Drug Warnings
If you are allergic to Dexamethasone+tobramycin or any other medicines, please tell your doctor. Consult your doctor before taking Dexamethasone+tobramycin if you are pregnant or breastfeeding. Dexamethasone+tobramycin is not recommended for children unless prescribed by a doctor. Let your doctor know if you have had myasthenia gravis (muscle weakness) or Parkinson’s disease, antibiotics like tobramycin may worsen muscle weakness. You are advised to remove soft contact lenses before using Dexamethasone+tobramycin as it contains a preservative that may cause eye irritation and discolouration of soft contact lenses. You can reinsert contact lenses after 15 minutes of using Dexamethasone+tobramycin. Do not use the topical non-steroidal inflammatory drug while using Dexamethasone+tobramycin. Dexamethasone+tobramycin contains dexamethasone; if you use a topical non-steroidal inflammatory drug and dexamethasone together, it may delay the healing of your eye wound. If you have diabetes, please consult your doctor before using Dexamethasone+tobramycin. The risk of intraocular pressure (glaucoma) and cataract formation is increased in diabetic patients. Dexamethasone+tobramycin may cause temporary vision problems (blurred vision), so be cautious while driving and operating machinery.

Patients Concern
Disease/Condition Glossary
Bacterial eye infection: Bacterial eye infection occurs when harmful bacteria invade any part of the eye, such as the eyeball, conjunctiva, or cornea. The common bacterial eye infections are conjunctivitis, keratitis, etc. Conjunctivitis (pink eye) is the inflammation or infection of the conjunctiva (white part of the eye) and the inner eyelid. It is a highly contagious infection that is spread by eye secretions. Symptoms include redness, itchiness, and discharge or crusting around the eye. Keratitis is the inflammation of the cornea that occurs due to frequent use of contact lenses, injury, diabetes, or surgery.
FAQs
Dexamethasone+tobramycin is used to treat bacterial eye and ear infections. It is used to treat eye infections such as conjunctivitis (infection of the outer white membrane of the eyeball) and corneal ulcers (ulcer that occurs in the transplant membrane of the eye called the cornea).
Dexamethasone+tobramycin contains tobramycin and dexamethasone. Tobramycin is an aminoglycoside antibiotic. It acts by inhibiting bacteria's growth. It binds to the proteins in the bacteria, disrupting the cell functions and eventually leading to bacterial death. Dexamethasone is a corticosteroid that blocks the production of certain chemical messengers (prostaglandins) that make the eye red, swollen, and itchy.
Do not take Dexamethasone+tobramycin on your own, as self-medication may lead to antibiotic resistance in which antibiotics fail to act against specific bacterial infections.
If you have diabetes, Dexamethasone+tobramycin can increase the risk of intraocular pressure (glaucoma) and cataract formation in diabetic patients. However, please consult your doctor before using Dexamethasone+tobramycin.
If you miss a dose of Dexamethasone+tobramycin, take the missed dose as soon as you remember it. However, if it's almost time for the next dose, do not take a double dose to make up for a missed one.
It is advised to use Dexamethasone+tobramycin only for the prescribed period as long-term usage of Dexamethasone+tobramycin may cause a new fungal eye infection (secondary infection). Prolonged use of corticosteroids may result in glaucoma, damage to the optic nerve, and defects in visual acuity and fields of vision. Intraocular pressure should be monitored if this product is used for ten days or longer.
