    Tobradex Warnings/Precautions

    Warnings/Precautions

    Corneal or scleral thinning. Glaucoma. Monitor for secondary infections, intraocular pressure and cataracts in prolonged use. Monitor blood levels in combined aminoglycoside therapy. Discontinue if hypersensitivity reactions occur. Do not wear contact lenses. Avoid abrupt cessation. Pregnancy. Nursing mothers.

    Warnings/Precautions

    • For topical ophthalmic use. Not for injection into the eye.

    • Cross-sensitivity to other aminoglycoside antibiotics may occur. Discontinue use and institute appropriate therapy if hypersensitivity reaction develops.

    • Prolonged use may suppress the host response and increase the risk of secondary ocular infections. Steroids may mask infection or enhance existing infection in acute purulent conditions and parasitic infections of the eye.

    • Prolonged use may result in glaucoma, with damage to the optic nerve, defects in visual acuity and fields of vision, and posterior subcapsular cataract formation. Routinely monitor intraocular pressure (IOP) even though it may be difficult in pediatric patients and uncooperative patients.

    • In those diseases that cause thinning of the cornea or sclera, perforations may occur with the use of steroids.

    • Prolonged use may result in overgrowth of nonsusceptible organisms, including fungi. Initiate appropriate therapy if superinfection occurs. 

    • Do not wear contact lenses during use or if signs/symptoms of bacterial infection are present.

    Pregnancy Considerations

    • No adequate and well-controlled studies in pregnant women. Increased risk of intra-uterine growth retardation with prolonged or repeated use during pregnancy.

    • Use during pregnancy only if potential benefit justifies the potential risk to the fetus.

    • Monitor infants born to mothers who received substantial doses of corticosteroids during pregnancy for signs of hypoadrenalism.

    Nursing Mother Considerations

    • Use caution when administered to a nursing woman.

    • It is not known whether topical administration of corticosteroids could result in sufficient systemic absorption to produce detectable quantities in human milk. 

    Pediatric Considerations

    Safety and effectiveness in pediatric patients below the age of 2 years have not been established. 

    Geriatric Considerations

    No overall differences in safety or effectiveness have been observed between elderly and younger patients.
