What is the dosage for tobramcyin-ophthalmic drops?

For all patients ≥ 2 months of age: Instill 1-2 drops into the infected eye every 4 to 6 hours. For severe infections, instill 2 drops into the infected eye every 30 minutes to an hour until improvement and then reduce to less frequent dosing intervals as indicated. Patients using tobramycin ophthalmic solution:

  • should wash their hands thoroughly with soap and water before and after using eye drops;
  • should be advised not to wear contact lenses during treatment of active eye infections;
  • must take care to avoid touching the dropper tip to the eye while administrating eye drops;
  • should wait for at least 5 minutes between applications if other eye drop preparations also are used.

Which drugs or supplements interact with tobramcyin-ophthalmic drops?

: Information on possible drug interactions with tobramycin ophthalmic drops is not found. However, as use of therapeutic levels of tobramycin eye drops does not result into clinically meaningful levels of drug in the blood, the potential for drug interaction with other agents is relatively low. Patients using other eye drops or those with pre-existing conditions of the eye should check with their doctor or pharmacists before using tobramycin ophthalmic drops.
