Introduction
Neurontin, also known by its generic name gabapentin, is a medication commonly prescribed to manage seizures in both adults and children with specific seizure disorders. This drug belongs to a category of medications called anticonvulsants.
In addition to reducing seizure susceptibility, Neurontin is also effective in alleviating certain types of nerve pain. It is available in tablet form or as an oral solution.
Key Information About Neurontin
Before starting Neurontin, there are several critical points to keep in mind:
- Hypersensitivity: Do not take Neurontin if you are allergic to gabapentin or any other ingredient in the medication.
- Breathing Concerns: If you are an older adult or have a condition like COPD, use this medication with caution. Difficulty breathing should be reported to your healthcare provider immediately.
Approved Uses of Neurontin
The FDA has approved Neurontin for managing the following conditions:
- Epileptic Seizures: Neurontin helps reduce the frequency of seizures in individuals with epilepsy. It can be used in combination with other seizure medications. However, it does not cure epilepsy and only works as long as it is taken.
- Postherpetic Neuralgia: This condition causes persistent nerve pain after a shingles infection, particularly in older adults. Neurontin is effective in relieving this type of nerve pain.
Off-Label Uses of Neurontin
Doctors may also prescribe Neurontin for conditions not officially approved by the FDA, including:
- Bipolar Disorder: This mental health condition causes sudden and extreme mood shifts, ranging from depressive lows to manic highs.
- Fibromyalgia: Characterized by widespread and chronic pain, fibromyalgia often causes sensations of burning, aching, or stabbing pain throughout the body.
- Migraines: Neurontin may help prevent migraines and manage chronic daily headaches, although more research is needed.
- Anxiety Disorders: Gabapentin is sometimes prescribed off-label for anxiety as it has a lower risk of abuse compared to benzodiazepines. However, there is still some potential for misuse.
A 2015 review highlighted the need for further research into gabapentin’s effectiveness in treating mental health disorders.
Things to Discuss Before Taking Neurontin
Before beginning treatment with Neurontin, consult your doctor about potential allergies and medical conditions. The active ingredient, gabapentin, can cause allergic reactions, including swelling of the tongue, throat, or face, hives, and breathing difficulties.
If you are pregnant, planning to become pregnant, or breastfeeding, inform your doctor. Evidence on gabapentin’s safety during pregnancy is limited, but one study suggested a possible link to an increased risk of heart defects in babies exposed to the medication during the first trimester.
Additionally, share your medical history with your healthcare provider, particularly if you have any of the following conditions:
- Liver disease
- Diabetes
- Depression
- Heart or lung disease
- Seizures
- Substance use disorders
Precautions and Contraindications
Breathing Risks
Neurontin can suppress respiratory function, particularly in older adults or individuals with chronic obstructive pulmonary disease (COPD). Seek medical help immediately if you experience breathing difficulties while taking this medication.
Mood Changes
Some individuals taking Neurontin have reported mood changes, including suicidal thoughts or behaviors. If you or someone you know notices sudden changes in mood or begins experiencing suicidal thoughts, seek immediate medical attention.
For mental health emergencies, contact the 988 Suicide & Crisis Lifeline or call 911 if you’re in immediate danger.
Other Gabapentin-Based Medications
Other brands of medications containing gabapentin include:
- Gralise: Primarily used to treat nerve pain following shingles (not available in the U.S.).
- Horizant: Approved for nerve pain and restless leg syndrome. This medication is typically taken with food in the evening.
Neurontin Dosage Guidelines
Your doctor will determine your dosage based on factors such as your condition, other medications you’re taking, and your ability to tolerate the drug. Below are general dosage recommendations:
- For Seizures:
- Initial dose: 300 mg once daily on Day 1, 300 mg twice daily on Day 2, and 300 mg three times daily on Day 3.
- Maintenance dose: 300–600 mg three times daily, depending on tolerability.
- Maximum dose: 3,600 mg per day (typically divided into three doses).
- For Nerve Pain:
- Initial dose: Same as for seizures.
- Maximum dose: 1,800 mg per day (e.g., three doses of 600 mg).
For Children
Neurontin is not recommended for children under three years old. Dosages for children are typically calculated based on body weight, with an initial dose of 10–15 mg per kilogram of weight divided into three doses per day.
How to Take and Store Neurontin
- You can take Neurontin with or without food.
- Swallow tablets whole without crushing or chewing.
- If you miss a dose, take it as soon as you remember. However, if it’s close to your next scheduled dose, skip the missed dose—never double up.
- Neurontin is often prescribed to be taken three times daily. Space your doses evenly throughout the day (e.g., morning, afternoon, and bedtime).

Most side effects of Neurontin are mild and temporary, but some may require medical attention.

Warnings and Interactions
- Drowsiness: Neurontin may cause drowsiness, and this effect can be heightened by alcohol. Avoid alcohol while taking this medication.
- Coordination Issues: The medication can slow reflexes and impair coordination. Refrain from driving or operating heavy machinery until you know how Neurontin affects you.

Neurontin is a widely used and effective medication for managing seizures and nerve pain. However, it’s crucial to follow your doctor’s instructions, monitor for side effects, and report any concerns promptly to ensure safe and effective treatment.
