Gabapentin 400 mg – Effective Relief for Nerve Pain and Seizures
Gabapentin 400 mg is a prescription-strength medication used to manage nerve pain and as adjunctive therapy for partial seizures. Belonging to the class of anticonvulsants, it is especially effective in treating postherpetic neuralgia, diabetic neuropathy, fibromyalgia, and epilepsy-related seizures. Gabapentin helps calm overactive nerves, reducing the discomfort associated with chronic neurological pain.
What is Gabapentin 400 mg Used For?
Gabapentin 400 mg is commonly prescribed for:
- Postherpetic neuralgia (nerve pain following shingles)
- Diabetic neuropathy (nerve pain due to diabetes)
- Partial seizures (as adjunctive therapy in epilepsy)
- Fibromyalgia (off-label use)
- Restless Legs Syndrome (RLS) (off-label)
This mid-range dose provides balance between symptom control and minimal side effects, making it suitable for long-term use under medical supervision.
How Does Gabapentin Work?
Gabapentin does not bind to GABA receptors but affects calcium channels in the brain and spinal cord. It modulates the release of excitatory neurotransmitters by acting on the alpha-2-delta subunit of voltage-gated calcium channels. This mechanism reduces nerve signaling and helps relieve chronic nerve pain and reduce seizure activity.
Benefits of Gabapentin 400 mg
- Powerful relief from nerve-related pain
- Reduces frequency and intensity of seizures
- Minimal drug interactions
- Non-narcotic and non-addictive when used as prescribed
