The 400 mg strength is a common capsule dose. It&#8217;s also frequently prescribed off-label for neuropathic pain, fibromyalgia, restless legs syndrome, anxiety, and sometimes as an adjunct for hot flashes or alcohol withdrawal.<\/p>\n<p class=\"mb-2 last:mb-0\"><strong>Key Facts (Evidence-Based):<\/strong><\/p>\n<ul>\n<li><strong>Mechanism:<\/strong>\u00a0Gabapentin binds to the alpha-2-delta subunit of voltage-gated calcium channels in the CNS, reducing excitatory neurotransmitter release (e.g., glutamate).
