Tobradex combines two active ingredients that work together. Tobramycin is an aminoglycoside antibiotic that kills susceptible bacteria by inhibiting their protein synthesis, effectively stopping the infection. Dexamethasone is a potent corticosteroid that suppresses the body's inflammatory response, reducing swelling, redness, and discomfort in the eye. Together, they treat the bacterial infection and the associated inflammation at the same time.

Tobradex scores a 65 out of 100 on our findability scale. While it's not on any FDA or ASHP shortage lists as of early 2026, intermittent availability issues have been reported at individual pharmacies due to supply chain variability and manufacturer production schedules. The generic version (Tobramycin/Dexamethasone) is generally easier to find than brand-name Tobradex or Tobradex ST. If your local pharmacy is out of stock, try using Medfinder to locate a nearby pharmacy that has it available.
Tobradex is most commonly prescribed by ophthalmologists and optometrists, particularly after eye surgery or for eye infections. It can also be prescribed by primary care physicians, family medicine doctors, emergency medicine physicians, and pediatricians. Telehealth prescribing is generally not available for Tobradex since it typically requires an in-person eye examination.
No, Tobradex is not a controlled substance. It does not have a DEA schedule and is not subject to the prescribing restrictions associated with controlled medications. However, it is still a prescription-only medication and requires a valid prescription from a licensed healthcare provider.
Serious side effects that require immediate medical attention include increased intraocular pressure (glaucoma risk with prolonged use), posterior subcapsular cataract formation, secondary fungal or viral eye infections, delayed wound healing, and sudden vision changes or vision loss. Contact your doctor immediately if you experience any of these.
