GENERIC NAME: tobramycin ophthalmic solution

BRAND NAME: Tobrex

DRUG CLASS AND MECHANISM: Tobramycin (Tobrex) is an antibiotic eye drop. Tobramycin is an aminoglycoside antibiotic that kills susceptible bacteria by blocking bacterial protein synthesis. Death of susceptible bacteria occurs because of the lack of functional proteins. Tobramycin treats only bacterial eye infections and does not work for other types of eye infections.

The FDA approved tobramycin eye drops in December 1980. In addition to eye drops, tobramycin is also available as 0.3% ointment which is also used to treat external bacterial infections of the eye.

PRESCRIBED FOR: Tobramycin ophthalmic solution is used to treat external eye infections caused by susceptible bacteria.

SIDE EFFECTS: Side effects associated with the use of tobramycin eye drops are mostly limited to the area(s) of application. Reported side effects include:

  • tearing,
  • swelling of the eye, and
  • itching, stinging, or burning of the eye.

Administration of eye drops may cause temporary vision problems including blurred vision. Patients should not engage in dangerous activities such as driving until their vision improves.

Although serious allergic reactions to tobramycin are unlikely, patient suspected of experiencing such a reaction must seek emergency medical help. Symptoms of a serious allergic reaction may include:

  • difficulty breathing,
  • swelling of the tongue,
  • face, or throat, and
  • severe rash.
