Gabapentin 100 mg: Uses, Dosage, Side Effects, Safety, and Frequently Asked Questions

What Is Gabapentin 100 mg?

Gabapentin 100 mg is a prescription medicine used to treat nerve-related pain (neuropathic pain) and certain types of seizures. It belongs to a group of medicines called anticonvulsants or antiepileptic medicines.

Although gabapentin was originally developed to treat epilepsy, it is now widely used for nerve pain conditions because of its ability to affect nerve signalling in the body.

Gabapentin works by reducing abnormal electrical activity in the nervous system and calming overactive nerve signals that may contribute to pain or seizures.

How Gabapentin Works

Gabapentin affects communication between nerve cells by influencing calcium channels involved in nerve signalling.

It works by:

• Reducing excessive nerve activity.
• Decreasing abnormal electrical signals in the brain.
• Helping control seizures.
• Reducing the intensity of certain types of nerve pain.

Gabapentin does not work like traditional painkillers and is generally not used for ordinary muscle aches or simple injuries.
