TOBI is clear and slightly yellow, and may change in color.
With age, TOBI®
(Tobramycin Inhalation Solution, USP)
may slightly change color, from light yellow to a darker yellow. This is normal as TOBI ages or as changes in temperature or exposure to light occur. TOBI should not be exposed to intense light. If TOBI is exposed to intense light, it will change color from light to dark yellow at a faster rate, and may eventually become brown with age.
A color change may not mean that there's any change in the quality of the product as long as it has been stored properly. TOBI is safe to use as it changes color as long as:
There are no particles floating in the solution
It is not cloudy
It has not been out of the refrigerator or at room temperature for more than 28 days
