Serious Side Effects Of Gabapentin

Breaking it Down. How Gabapentin REALLY works on your brain & CNS

In emergency cases, some people might struggle with breathing problems and kidney issues. These are likely among those who have had lung or kidney issues in the past, or who are using gabapentin with other substances .

In very rare cases, individuals might suffer an allergic reaction that could be very dangerous. Swelling in the mouth, tongue or throat, or very intense itching, usually signals the onset of a critical allergic reaction that requires immediate medical attention.

Side effects of gabapentin carry the risk of developing adverse physical effects in both the short-term and long-term for patients. The American Journal of Medicine carried the results of a study that suggested that people who had a pre-existing kidney problem before taking gabapentin are at risk for developing gabapentin toxicity, which can be fatal.

Gabapentin is broken down into its chemical constituents in the kidneys, and those who have kidney problems are in danger of the gabapentin components staying in their systems for longer than necessary, leading to gabapentin toxicity. Gabapentin toxicity could also develop in people who take more gabapentin than they should, whether out of a misguided desire for relief or for recreational purposes.

Side Effects Of Gabapentin On Brain Injury

While gabapentin can be beneficial for brain injurypatients, it does have serious potential side effects.

Some of the most common side effects of gabapentin include:

  • Abnormal eye movements
  • Trouble speaking
  • Swelling in hands and feet

In addition, many brain injury patients experience heightened anxiety and restlessness when taking gabapentin. But this is more common in patients with cognitive impairments.

Imaging And Processing Method

MRI data were acquired on a 4 T MedSpec system using an 8-channel transmit-receive head coil and a Siemens Trio console . A magnetization prepared rapid gradient and a turbo spin-echo sequence were used to acquire 3-D sagittal T1-weighted and 2-D axial T2-weighted anatomical images, respectively. The images were then displayed on the scanner console for the prescription of up to five different MRS volumes-of-interest acquired in two scanning sessions . After VOI-specific 3-D shimming and optimization of water suppression, J-edited GABA spectra were acquired from the POC using a modified MEGA PRESS sequence , followed by the acquisition of a water spectrum from the same VOI. This was then followed by the acquisition of a stimulated echo acquisition mode sequence from the same VOI location. Additional STEAM metabolite and water spectra were acquired from the ACC and the right DLPFC , with VOIs placed to maximize the inclusion of as much gray matter tissue as possible. For this analysis, GABA spectra from the ACC and DLPFC were available from all GBP patients but only from two GBP+ patients, so that potential GABA differences in these VOIs could not be analyzed statistically.

Gabapentin: How Does It Work

Gabapentin-Neurontin is a class of drug that has analgesic effects, this simply means that this drug reduces pain. The mechanism to how Gabapentin works and metabolizes in our body can be quite complicated. But, if youre really interested in learning more about the pharmacology of this drug, well keep things simple.

First, its important to know that Gabapentin is an analog of the neurotransmitter known as gamma-aminobutyric acid . The term analog simply means that the Gabapentin molecules will structurally look very similar to the GABA neurotransmitter. Now, in order for our bodies to release a specific neurotransmitter, there has to be an influx of calcium through the cell membranes. The influx of calcium occurs as a result of channels called voltage-gated calcium channels.

Now, you might be wondering, why are these calcium channels important? what do they do? and how do they affect Gabapentin?

Voltage-gated calcium channels play an important role in mainting intracellular function. Two of their major functions often involve the contraction of the muscles and normal brain functioning. if we want to get more into the physiology, then another important point to consider is the fact that Gabapentin seems to have an effect on these channels, inhibiting the threshold for a sub-unit of voltage-gated calcium channels. This subunit is believed to play a role in the attenuation of pain and the neurons associated with it.

Medications To Increase Gaba

How to Effectively Deal with Gabapentin Withdrawal (OUTLINE)

Doctors may prescribe medicines that increase the amount of GABA or stimulate the same neurotransmitters in the brain to treat some medical conditions, such as epilepsy.

For example, benzodiazepines act on many of the same neurotransmitter receptors as GABA. According to one study, people who have depression may have reduced GABA levels in the brain. The use of benzodiazepines may be beneficial in those instances.

Doctors also prescribe the medication gabapentin , which is chemically similar to GABA to reduce seizures and muscle pain.

However, doctors are not clear whether the therapeutic effects of these medications are related to their effect on GABA receptors or whether they work in other ways.

  • candies, and more

Manufacturers produce GABA supplements by fermenting a form of lactic acid bacteria.

However, the FDA do not regulate dietary supplements in the same way as medications. Therefore, consumers should exercise caution as to where they purchase the product from and only buy from reputable vendors and companies.

Independance Motivation And Hope

My son Sharat suffered a severe traumatic brain injury 23 years ago leaving him with Aphasia and right sided weakness from his vision,hearing to his limbs. The lockdown in June was a great challenge for him as his caregivers stopped coming, no gym workouts and no outings for a coffee.

Being his mother and primary carer I feared that this was a hotbed for depression. I scoured the net and chanced upon FlintRehab. As there was a trial period it was safe for us to risk getting it across to Auckland.

His OT checked it out and felt that it was ideal. I can honestly second this.

He enjoys working on it and now after three months can do it on his own. His left hand helps his right hand. The FitMi video explains and shows him what to do, it gives him marks and applauds him too!!

He has to use both sides of his brain. The caregivers are OT students who returned enjoy working on it with him.

In three months there motivation built up in him with a drive to use his right hand. There is definitely a slight improvement in his right hand.

This encourages him as well as the caregivers to try harder.His overall mood is upbeat. He enjoys it, so much so, that it doesnt matter if his caregiver is away.

FitMi is a blessing.

Induction Of Seizures By Sub

To confirm the anticonvulsant effects of these drugs, 24 hours after end of drug administration, animals in groups B, C, D and E were kindled for seizure at sub-maximal electric shock at a current of 99 mA, pulse width of 0.5 at 100 Hz for duration of 2 s using electroconvulsometer produced by Ugo Basile. Each animal induced for seizure was observed for the time taken to experience tonic flexion, tonic extension and clonic convulsion.

What Is Gabapentin Used For

Gabapentin is an anticonvulsant medication primarily used totreat partial seizures and neuropathy.

It is also one of the few drugs that can cross the blood-brain barrier and enter the central nervous system. It works by changing the way nerves send messages to the brain.

For people without brain damage, pain is detected in thefollowing way:

  • Nociceptors in the skin send pain signals via the peripheral nerves to reach the dorsal horn in the spinal cord.
  • The dorsal horn passes these signals on to the thalamus in the brain.
  • The thalamus sorts out the pain signals and relays them to different parts of the brain, such as the somatosensory cortex.

These parts of the brain translate sensation into pain.

After a brain injury, however, this process can become distorted, depending on which part of the brain the injury damaged. As a result, your brain can get confused and think your body is being harmed when in reality it is not. This causes neuropathic pain.

Gabapentin works by suppressing the activity of pain nerves,which can help relieve pain. By calming down the nerves it can also reduce seizurefrequency.

Pain and seizure management is the most common use for gabapentin after brain damage. But it has also been used successfully to treat autonomic dysfunction.

Treatment With Gabapentin: Important Things To Know Before Taking Gabapentin

Before you start gabapentin therapy, you should have a thorough medical exam to rule out any medical issues. This includes any blood or urine tests. Medical evaluations are important as gabapentin can induce hormonal imbalances. Like any other drug, you should not take gabapentin if youre allergic to it.

There are side effectsmore on that in a minute. But a few of the most important things your doctor will want to find out before prescribing gabapentin is if you have or have had any of the following:

  • Diabetes
  • Kidney problems
  • Liver or heart disease
  • Lung disease
  • Mood disorders, depression or bipolar or if youve ever thought about suicide or attempted suicide
  • Seizures

You should also know that not enough studies have been done to understand the exact risks of gabapentin if youre pregnant or breastfeeding.

Why Is This Medication Prescribed

GBP at 16 mg/kg/day, in comparison between physiological weight in human and body weight of the animalsand CBZ at20 mg/kg/day correspond to the usual anticonvulsive dose in humans which is effective in preventing kindled seizure in Wistar rats. Groups A and B rats served as the control and received 0.1 ml/day of normal saline intraperitoneally for 28 days. Group C received 16 mg/kg body weight of GBP i.p. for 28 days, Group D received 20 mg/kg BW of CBZ i.p. for 28 days while Group E received sub-therapeutic doses of both GBP 8 mg/kg body weight and CBZ 10 mg/kg body weight for 28 days. GBP and CBZ obtained from Sigma Chemicals, UK.

Workout Recovery And Muscle Building


A 2019 research study asked 21 healthy males to take a supplement with whey protein or whey protein plus GABA once a day for 12 weeks.

The participants performed the same resistance training exercises twice a week, and the researchers measured the results. The researchers found that the combination of whey protein and GABA increased levels of growth hormone compared to whey protein alone.

Although this was another small study, the researchers concluded that GABA supplements might help to build muscle and assist in workout recovery. They recommended that researchers conduct more studies.

What If I Forget To Take It

If you forget a dose, take it as soon as you remember. If it is within 2 hours of the next dose, it is better to leave out the missed dose and take your next dose as normal.

Never take 2 doses at the same time. Never take an extra dose to make up for a forgotten one.

If you have epilepsy, it’s important to take this medicine regularly. Missing doses may trigger a seizure.

If you often forget doses, it may help to set an alarm to remind you. You could also ask your pharmacist for advice on other ways to help you remember to take your medicine.

How Long Does It Take To Work

After you start to take it for nerve pain, you should see an improvement in the intensity of the pain over one to two weeks. However, for some people, it may take longer for gabapentin to work to reduce nerve pain whereas there are others who may feel a difference right away.

You will need to visit your medical practitioner on a scheduled to date so he/she can conclude if the nerve pain medication is working to relieve your pain or not. In the event it is not, they may either increase the dosage or switch your medication for another one.

If you do notice a difference in the level of pain you experience on gabapentin, your medical practitioner will advise you to continue taking it. You cannot become addicted to gabapentin, hence making it safe to take for continuous use.

Even though the chances of becoming addicted are low because its addictive potential is low, you may experience withdrawal symptoms, which is an essential part of physical addiction.

Even though the occurrence of someone becoming addicted is less, if they do become addicted to it, the treatment to stop being dependent on the medication is quite complex, but doable.

Here are common signs of a person who has developed a dependency on gabapentin:

What Other Information Should I Know

Keep all appointments with your doctor.

Before having any laboratory test, tell your doctor and the laboratory personnel that you are taking gabapentin.

If you use a dipstick to test your urine for protein, ask your doctor which product you should use while taking this medication.

Do not let anyone else take your medication. Ask your pharmacist any questions you have about refilling your prescription.

It is important for you to keep a written list of all of the prescription and nonprescription medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.

How Should This Medicine Be Used


Gabapentin comes as a capsule, a tablet, an extended-release tablet, and an oral solution to take by mouth. Gabapentin capsules, tablets, and oral solution are usually taken with a full glass of water , with or without food, three times a day.

These medications should be taken at evenly spaced times throughout the day and night no more than 12 hours should pass between doses. The extended-release tablet is taken with food once daily at about 5 PM. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take gabapentin exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Gabapentin extended-release tablets cannot be substituted for another type of gabapentin product. Be sure that you receive only the type of gabapentin that was prescribed by your doctor. Ask your pharmacist if you have any questions about the type of gabapentin you were given.

Swallow the extended-release tablets whole do not cut, chew, or crush them.

If your doctor tells you to take one-half of a regular tablet as part of your dose, carefully split the tablet along the score mark. Use the other half-tablet as part of your next dose. Properly dispose of any half-tablets that you have not used within several days of breaking them.
