Hi. Thanks for your question. I am a board certified neurologist in the U.S.
In terms of treatment for neuropathy, there are various options available, including Lyrica. Maximum dosing of Lyrica at any one time is typically 150mg, so it could be possible to increase the dose if there are no or minimal side effects. There are other medications also available for neuropathy, which include but is not limited to gabapentin, nortriptyline, Cymbalta, venlafaxine, valproic acid, tramadol, and carbamazepine.
Therefore, if one agent is not successful to control the symptoms, then other medications can be tried either alone or in combination.
Also, sometimes people with neuropathy will use a cream such as Capsaicin to hopefully obtain relief from neuropathy.
Of course, it is important also to try to determine the cause of the neuropathy to see if the condition is reversible, which would need consultation and evaluation by a neurologist. Conditions such as B12 deficiency, thyroid disease, kidney dysfunction, and diabetes are a couple potential causes to be considered. Reversing the cause of neuropathy can sometimes improve symptoms.
