Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice.
Wow, it's nice when the amount of narcotics is under a fatal dose. First, find out why there is falling. It is not usually from the drugs but the risk is certainly high enough to be found in clinical surveys. There can be
partial paralysis from the disk. There can be
dizziness or even
brain injury from the fall. These are each quite uncommon, but then again, most people don't have the falls! So, something is certainly going on and it is only Most likely the medications but does not have to be from them.
Then, soma has alternatives with less falling. These include chemically similar to soma
robaxin and chemically quite different cyclobenzaprine(
flexeril).
There are other drugs like
aspirin for pain that have less falling than
norco, but frankly at 30 mg per day or less, I'm not sure they are even safer and they are less likely to work on the pain. One should try them just to verify the falling stops when the narcotics are not present (12 hrs after stopping them).
Hope I have answered your query. Let me know if I can assist you further.
