If your urine is not clear, and you are having swelling in the feet and the hands -- then I would be concerned that your kidney function is not optimal, causing you to retain fluid (and hence cause swelling in the extremities).
I'm not sure that this would be directly related to the levetiracem.
Swelling is not generally a side effect of this medication, so I would have your doctor do some simple tests first, such as bloodwork, to look at your kidney function. They would also want to look at other things, such as heart function as well.
Certainly, if this is thought to be related to the medications, stopping the medication and switching to another is a possibility. But I would start with your primary care doctor.
