Gabapentin(A guide)

Gabapentin is a nerve pain medication and anticonvulsant that is used to treat seizures and pain caused by shingles. 

What is gabapentin? 

Gabapentin is a medication used to control partial seizures and to treat epilepsy.

It cannot cure epilepsy and will only work to keep seizures at bay if it is taken continuously.

Gabapentin can also be used in adults to treat postherpetic neuralgia, which is a pain that occurs after an episode of shingles.

It should not be used for routine pain that is caused by minor injuries. 

This medication is available in a capsule, tablet, solution, or suspension.

Do not take gabapentin unless it is prescribed by your doctor for seizures or nerve pain caused by shingles.

Can gabapentin be used to treat depression, mania, and anxiety? 

Gabapentin is not approved to be used in the treatment of mental health disorders.

There are studies in the works that are looking at how gabapentin can treat mood disorders or tardive dyskinesia (a movement disorder), but faulty case studies have said that gabapentin can help patients with treatment-resistant depression and other mood disorders without unwanted side effects. 

If you are experiencing anxiety, depression, or any other psychiatric disorder, do not take gabapentin or seek it out from an unreliable source.

This is very dangerous and can cause many unwanted side effects, as discussed below. 

What is some important information that I should know before taking gabapentin?

If you have any allergies to medications or any foods, dyes, preservatives, or animals, it is important to let your doctor know right away before taking gabapentin. 

Gabapentin has not been approved to treat seizures or postherpetic neuralgia in children younger than 3 years of age. 

It has not been studied whether or not gabapentin is safe for women breastfeeding or for geriatric patients.

Women who are breastfeeding should discuss with their doctors and weigh the potential benefits and risks when deciding to taking gabapentin while breastfeeding.

Elderly patients are more likely to have unwanted effects from age-related problems, so doctors must be cautious when prescribing and managing the dose of gabapentin. 

Is it possible to overdose on gabapentin?

Yes, it is possible to overdose on gabapentin.

Seek emergency medical help if someone you know has collapsed, had a seizure, has trouble breathing, or is unresponsive.

Symptoms over overdose include the following:

·      Double vision

·      Slurred speech

·      Drowsiness

·      Diarrhea

If you are taking any of the medications listed below, it is imperative to discuss them with your doctor, since these may increase the risks of developing side effects from gabapentin:
