What is Gabapentin 100mg Used For?

Gabapentin belongs to a group of medicines used to treat epilepsy and peripheral neuropathic pain . Its primary FDA-approved uses include:

1. Epilepsy (Partial Seizures)

Gabapentin is indicated as adjunctive therapy in the treatment of partial seizures with and without secondary generalization in adults and children aged 3 years and older . It can also be used as monotherapy in adults and adolescents aged 12 years and above .

For epilepsy, gabapentin works by reducing abnormal electrical activity in the brain, thus helping to prevent seizures .

2. Peripheral Neuropathic Pain

Gabapentin is indicated for the treatment of peripheral neuropathic pain, which includes:

• Painful diabetic neuropathy (nerve damage caused by diabetes)

• Post-herpetic neuralgia (nerve pain that persists after an episode of shingles)

• Trigeminal neuralgia (severe facial pain)

Pain sensations from neuropathic pain may be described as hot, burning, throbbing, shooting, stabbing, sharp, cramping, aching, tingling, numbness, or pins and needles .

Off-Label Uses

How Gabapentin Works

Gabapentin is an antiepileptic medication that works through a unique mechanism. When given for epilepsy, it is believed to work by reducing abnormal electrical activity in the brain, thus preventing seizures .

For nerve pain, gabapentin works differently—it blocks pain by interfering with pain signals traveling through the damaged nerves and the brain . Specifically, gabapentin binds with high affinity to the alpha-2-delta subunit of voltage-gated calcium channels on presynaptic neurons. This reduces calcium influx during depolarization, leading to decreased release of excitatory neurotransmitters such as glutamate, substance P, and norepinephrine .

Important Safety Information

Contraindications (Do Not Use)

Do not take gabapentin if you are allergic (hypersensitive) to gabapentin or any of the other ingredients of this medicine .

Warnings and Precautions

• Do Not Stop Suddenly: If the gabapentin dose is reduced, discontinued, or substituted with an alternative medication, this should be done gradually over a minimum of 1 week. Abrupt withdrawal of anticonvulsants may precipitate seizures .

• Suicidal Thoughts: Antiepileptic drugs, including gabapentin, have been associated with an increased risk of suicidal thinking and behavior .

• Breathing Problems: Gabapentin has been associated with severe respiratory depression, especially when combined with opioids or in patients with compromised respiratory function .

• Concomitant Use with Opioids: Caution is advised when prescribing gabapentin with opioids due to risk of CNS depression. Co-prescription of opioids and gabapentin was associated with an increased risk for opioid-related death compared to opioid use alone .

• Dizziness and Somnolence: Gabapentin treatment has been associated with dizziness and somnolence, which could increase the occurrence of accidental injury (fall) .

• Driving and Operating Machinery: Do not drive or do anything requiring concentration until you know how gabapentin affects you .

Drug Interactions

• Antacids: If gabapentin and antacids containing aluminum and magnesium are taken at the same time, absorption of gabapentin may be reduced. It is recommended that gabapentin is taken at least 2 hours after taking an antacid .

• Morphine/Opioids: Patients who use gabapentin and morphine concomitantly may experience increases in gabapentin concentrations. The dose of gabapentin or concomitant treatment with CNS depressants including opioids, should be reduced appropriately .
