Gabapentin 400 mg  is an anticonvulsant used to treat epilepsy and postherpetic neuralgia.

Gabapentin appears to function by affecting the activity of molecules called neurotransmitters, which send information between nerve cells, and altering electrical activity in the brain.

 Horizant, Gralise, and Neurontin are some of the brand names for gabapentin 400mg. The drug can be taken as a capsule, pill, or liquid.

 The uses, dosing, and side effects of gabapentin are discussed in this article. We also look into the hazards and other safety concerns that come with it.

 The primary purpose of gabapentin is to prevent or control seizures. It works by reducing seizure intensity and frequency by relaxing nerve activity.

 The medicine is suitable for both children and adults. Neurontin is a brand of medication that can be used to treat one type of epilepsy in children as young as three years old. To treat epileptic symptoms, some people use gabapentin 400 with other drugs.

 Gabapentin can also assist with post-herpetic neuralgia, which is a burning or stabbing nerve pain that is a typical shingles effect.

According to a 2017 evaluation, a daily dose of 1,200 milligrammes of oral gabapentin can alleviate moderate to severe nerve pain caused by shingles or diabetes.


The right dosage of gabapentin depends on several factors, including:


  the type and brand of gabapentin

  the product's strength

  the ailment

  the person's renal function

 their weight, age, and general health

  the number of daily doses, the hours between doses, and the length of time a person takes gabapentin will differ depending on the individual.

 Some versions of gabapentin should be taken with food, although it is not necessary for others.

 People who have been prescribed Horizant gabapentin for RLS should only take it in the evening or at night.

  Some kinds or dosages require that the tablets be broken in half. Use the remaining half with your next dose, or as soon as possible.

  Always swallow extended-release gabapentin pills whole, not broken or chewed.

 Take only the appropriate dose of gabapentin and do not take it for longer than suggested. If a person forgets to take a dose, they should follow the recommendations on the labelling or seek help from a pharmacist.


Side effects

 Gabapentin's side effects include dizziness and drowsiness.

 Gabapentin has the potential to induce adverse effects. According to a 2017 study, these side effects were slightly more common in gabapentin users than in placebo users.

 Dizziness, tiredness, and water retention (swelling of the arms, hands, legs, and feet) were the most common side effects, which were reported by 10% of gabapentin users.

 Serious side effects were uncommon, and those who took the placebo had the same results.

Gabapentin side effects are more likely to affect children and the elderly. The following are examples of possible negative effects:

 back or chest discomfort




 upset stomach

 increased hunger and weight gain

  hazy vision


 mood swings




 flu-or cold-like symptoms

 hoarseness and xerostomia

 memory loss

 mouth ulcers

 shortness of breath

 a pharyngitis and swollen glands


 urinary problems


 uncontrollable eye-rolling



In children, a number of the more common adverse reactions are:


 anxiety, depression, or other mood changes

 behavioral problems

 changes in performance at college


 lack of concentration

 Individuals taking gabapentin should ask their doctors about any side effects that occur, especially if they're severe, ongoing, or worsen .
