Tobradex Eye Ointment is prescribed as an antibacterial medication for treating the symptoms of bacterial conjunctivitis, uveitis, keratitis, and as a preemptive move after ophthalmic surgery to avoid a possible infection and to reduce inflammation. There are two active ingredients in Tobradex Eye Ointment; Tobramycin is an antibiotic and Dexamethasone is a corticosteroid.
If your conjunctivitis is strongly suspected to be caused by bacteria, your doctor may recommend you begin treatment with Tobradex Eye Ointment while awaiting test results. If it turns out that it is caused by a virus, you will stop using this antibiotic and be instructed to treat the symptoms only to provide relief while the infection has run its course.
Uveitis and keratitis are both inflammatory conditions. Uveitis affects the colored part of your eye (iris), and keratitis involves corneal inflammation. Due to the suppression of your immune system from Dexamethasone, infection is a real threat so Tobramycin is working to prevent that from occurring.
Tobramycin is the antibiotic that will work to get inside the bacterial cell and cause interference with the bacteria’s ability to properly read the genetic coding so the bacteria cannot reproduce. It also causes a disruption in creating an essential protein the bacteria need for a protective cell membrane. Without this protein, the integrity of their cell is compromised and holes form that allow the contents to leak out while other substances seep in so the bacteria die.
Dexamethasone is a potent corticosteroid that works to decrease inflammation by inhibiting the production of inflammatory chemicals, including prostaglandins. The small blood vessels contract which helps to decrease the flow of blood and plasma that is rushing to the affected area of your eye. Swelling, pain, and inflammation diminishes.
Tell your doctor if you are pregnant, trying to become pregnant, or are breast feeding to be certain if there are risks to using Tobradex Eye Ointment. Discuss other medical conditions or allergies you have and list any OTC or Rx drugs you currently take or use, including herbal remedies and dietary or vitamin supplements, to determine if there may be any adverse reactions to Tobramycin/Dexamethasone.
Tobradex Eye Ointment is a short-term ophthalmic medicine that should only be administered for the time period stated by your doctor. Prolonged use of a corticosteroid can delay corneal healing. Do not wear contacts during treatment unless otherwise indicated by your doctor. Your vision will be temporarily impaired so do not drive or take part in any activity that could be unsafe without proper vision. Keep Tobradex Eye Ointment out of children’s reach and never share any medication that is prescribed for you.
