Tobramycin and Dexamethasone Dosage

When treating certain eye conditions with tobramycin and dexamethasone, the dosage will vary depending on the form of the medication used (either drops or ointment) and the severity of the eye problem. The recommended dose for the drops is one to two drops into each affected eye every four or six hours. The ointment is used up to three or four times a day.

An Introduction to Your Tobramycin and Dexamethasone Dosage

The dose of tobramycin and dexamethasone (Tobradex®) your healthcare provider recommends may vary, depending on the particular form (ointment or suspension) and the severity of the eye problem. As is always the case, do not adjust your dosage unless your healthcare provider specifically instructs you to do so.
 

Dosing for the Eye Ointment

The recommended dose for the eye ointment is a "small amount" (about a ½-inch ribbon) applied to the affected eye(s) up to three or four times daily. Many people find the idea of using an ointment in the eye to be quite strange and unfamiliar, but you can rest assured that this product is intended for use in the eye.
 

Dosing for the Eye Suspension

The dosing is slightly different for tobramycin and dexamethasone suspension (drops). The standard dosage is one or two drops into each affected eye every four or six hours. During the first 24 to 48 hours, your healthcare provider may recommend a higher dosage of one to two drops every two hours (to help get the inflammation under control).
 

General Information on Using Tobramycin and Dexamethasone

Some considerations for people using tobramycin and dexamethasone include the following:
 
  • This medication comes in the form of an eye suspension (drops) and an eye ointment. It is typically used in the affected eye(s) 3 to 12 times a day (depending on whether the ointment or the drops are used and the severity of the problem).
     
  • In order to prevent contamination of the drops, do not touch the tip of the dropper or ointment tube to any surface, including the surface of the eye.
     
  • To use the ointment, make a small pocket in the lower lid by gently pulling down on the cheek just below the eye. Apply about ½ an inch of ointment carefully, and then look downward before closing your eye. The ointment may temporarily cause blurred vision.
     
  • When using the drops, make sure to shake the bottle well before each use.
     
  • For the medication to work properly, it must be used as directed.
     
  • If you are unsure about anything related to your tobramycin and dexamethasone dosage, please talk with your healthcare provider, nurse, or pharmacist.
