Ultimate Guide to Tobramycin Ophthalmic Solution 0.3%

Meet the Pet Eye Infection Protector: Tobramycin Ophthalmic Solution 0.3%!

Tobramycin Ophthalmic Solution 0.3% is a prescription (e.g., conjunctivitis). Generic alternative Tobramycin for dogs and cats is a two to three times daily solution that is applied outside of the eye, which eases their discomfort during the healing process.

How does Tobramycin Ophthalmic Solution 0.3% work?

Tobramycin Ophthalmic Solution 0.3% is a topical aminoglycoside and a highly potent, broad-spectrum antibiotic that stops bacterial growth. Tobramycin Ophthalmic Solution 0.3% treats external eye bacterial infections by fighting and preventing the spread of particularly dangerous Gram-negative infections.

Tobramycin is especially effective against species of Pseudomonas bacterium, such as conjunctivitis. The aminoglycoside enters the bacterial cell wall and binds with the cell 's ribosomes which are fundamental to protein synthesis for the production of the bacteria. Then the aminoglycoside inhibits protein synthesis and causes the bacterial cell to die.

Tobramycin 's other additives are inactive ingredients and a preservative.

How is Tobramycin administered?

Tobramycin 's sterile solution is applied topically outside of the pet 's eye, not inside. Cradle the pet 's head and face upward towards the ceiling before applying the solution around the eye, and don 't allow your pet to wipe away the solution until it is absorbed.

Wash your hands before and after application. Do not touch the sterile applicator for this will contaminate the solution.

In terms of Tobramycin dosage, the usual dosage is 1 to 2 Tobramycin drops to each affected eye every 12 hours. However, a licensed veterinarian will dictate the pet 's specific dosage to prevent paralysis from an accidental overdose. Twice a day applied for seven days should show improvements in your pet 's infection and suffering.

The medication belongs to the aminoglycosides class of drugs. In certain other cases, the medication also finds use in controlling bacteria caused by respiratory infections, bite wounds, or injury-borne infections, and also those affecting the skin and ear of animals. Tobramycin, the active ingredient used in the medication possesses active antibiotic properties, which when administered restricts bacterial growth by delaying the protein synthesis. Though the drug is not approved for use in animals, most veterinarians have agreed to use the medication on dogs. However, tobramycin is a prescription drug and is available in various ophthalmic preparations as an injectable solution, suspension as well as ointment. 


Use the medication only by prior consent from a veterinarian. The usual suggested dosage of the medication is 1 mg/lbs in a gap of 8 hours. The dosage administration can be intravenous, intramuscular, or subcutaneous.  Follow the application instructions on the box, and adhere to your veterinarian’s dosage instructions. Your veterinarian will likely instruct you to use the entire container of the solution, even if symptoms appear to have diminished or disappeared entirely.

Be sure to wash your hands before administering the solution, and be careful not to touch the tip of the applicator. The medicine is sterile, and touching it could contaminate the tip.

To apply, you’ll cradle your pet’s face, and encourage their face upward toward the ceiling. Gently apply the solution around the eye, and don’t allow your pet to wipe the solution away. Don’t forget to praise your pet for cooperating.
