The tinnitus from ototoxicity is generally high pitched, and in this case, can worsen over time, resulting in multiple tones across both ears. People have noted that their tinnitus has remained even after most other side effects have disappeared.

Quinolones such as Levaquin and Cipro have been known to be ototoxic. There have been many cases of quinolone induced tinnitus, many of which are long term. It is known that quinolones can cause serious damage to hair cells within the cochlea.

The hair cells in the cochlea are specific cells that detect sound and send respective signals to the brain which interprets these signals as sound. Usually, damage to the hair cells will only result in hearing loss. However, in many cases, tinnitus may also occur. One explanation of this is that the hair cells have been damaged, and send constant signals to the brain, even in the absence of external sound. There are many reports of quinolone caused tinnitus that are multi-tone, in that there are different pitches across both ears. This occurence could be because the quinolones have remained inside the cochlear fluids, causing more damage to other hair cells, which results in multiple pitches or tones. On the other hand, tinnitus from other causes such as loud noises, do not worsen over time and usually have only one tone.

Tinnitus is a very mentally distressing syndrome that could result in permanent hearing loss. Tinnitus may also lead to depression, and may even prevent the sufferer from functioning in daily activities. If you are someone who is suffering from Levaquin induced tinnitus, tinnitus is probably going to be the least of your concerns. If not already, you may probably be suffering from more adverse reactions in the near future. It must be remembered that delayed reactions from quinolones are a serious possiblity.
