My mother recently took cipro for 10 days for a UTI. Since that time, her hearing is about half what it once was. The loss was very fast. I looked up hearing loss as a side effect of cipro and found that it is possible. Has anyone else noticed this with their loved one? Since I now know my mother could be sensitive to the drug, we won't be using it again. From what I read, the effects are not reversible. I would recommend anyone whose parent is taking cipro to pay attention to possible hearing loss. What a terrible side effect when it does happen.
