Tobramycin (TOBI) is an antibiotic used to treat bacterial infections in the lungs, particularly for those with Cystic Fibrosis.

This is a serious side effect that can have long-term consequences and should be monitored closely by a healthcare professional.

However, it is important to monitor liver function while taking the medication as it can affect the liver in some cases. Option D, insomnia, is also not a common side effect of Tobramycin (TOBI).

It is important to note that while these side effects may occur, it is not guaranteed that every individual taking Tobramycin (TOBI) will experience them. It is important to discuss any concerns or potential side effects with a healthcare professional
