The tobramycin aggressively kills any bacteria invading a dog's eye. But the dog's natural immune responses may mistake the tobramycin as an invader and destroy it before it can kill the invading bacteria. Therefore, the dexamethasone is added to suppress the dog's immune system so the tobramycin can kill the bacteria.

Tobradex generic -TOBA eye drops contain two active ingredients, dexamethasone and tobramycin. Dexamethasone belongs to a group of medicines known as corticosteroids that are used for reducing inflammation. Tobramycin is an antibiotic that is included in these drops to prevent infections with bacteria.
Corticosteroids are hormones produced naturally by the adrenal glands that have many important functions, including control of inflammatory responses. Dexamethasone is a synthetic corticosteroid that can be administered into the eyes to decrease inflammation.
Eye inflammation can occur as a result of trauma to the eye during eye surgery and is caused by the release of substances that are important in the immune system. These substances cause blood vessels to widen, resulting in the affected area becoming red, swollen and painful. Corticosteroids work by acting within cells to decrease the release of these substances in a particular area, thereby reducing swelling and redness.
Tobramycin belongs to a group of antibiotics called aminoglycosides. These antibiotics have the ability to kill a wide variety of bacteria. Tobramycin works by affecting the production of certain proteins by bacteria. These proteins are necessary for the bacteria's survival. Tobramycin causes the bacteria to produce abnormal and faulty proteins, which ultimately kills the bacteria.
Types
Toba comes in eye drops and eye ointment. According to the manufacturer, each millimeter contains 0.3% tobramycin and 0.1% dexamethasone. The drops need to be shaken before use in order to be sure because the active ingredients settle to the bottle's bottom. Both of these can only be purchased with a prescription.
Possible side effects that would happen right away are itchy eyes, swollen eyelids, facial swelling, severe diarrhea and vomiting. Possible long term side effects include a secondary infection because of the suppression of the immune system, deafness, coordination problems resulting from inner ear damage, kidney damage or liver damage. Tobradex may also cause a dog already on diuretics to become quickly dehydrated.
Cautions
Because of the risks of deafness and loss of coordination, Tobradex should not be given to therapy dogs, search and rescue dogs, dogs that work on farms or ranches, pregnant dogs, nursing dogs or puppies. Because of the risk to the kidneys and liver, dogs with liver or kidney problems or very old dogs should not be given Toba
