Neurontin (Gabapentin) – Complete Product Information

What is Neurontin (Gabapentin)?

Neurontin is the brand name for gabapentin, a prescription medication approved by the U.S. Food and Drug Administration (FDA). It belongs to a class of drugs known as anticonvulsants and is primarily used to treat certain types of nerve pain and seizures.

Gabapentin works by calming abnormal electrical activity in the brain and altering how the body perceives pain. It is not a narcotic, but it is a controlled substance in some U.S. states due to potential for misuse.

What is Neurontin Used For?

According to the FDA, Neurontin is approved to treat:

• ✔️ Postherpetic neuralgia – nerve pain that persists after shingles.
• ✔️ Partial-onset seizures – as an add-on therapy in adults and children.
• ✔️ Restless legs syndrome – for gabapentin enacarbil (a related formulation), not Neurontin directly.

Doctors may also prescribe it off-label for other neuropathic pain conditions, fibromyalgia, anxiety, and insomnia. Always follow your prescriber's instructions.

Available Dosages and Forms

Neurontin is available in several strengths. The most common include:

• Capsules: 100 mg, 300 mg, 400 mg
• Tablets: 600 mg, 800 mg
• Oral solution: 250 mg/5 mL

Generic gabapentin is available in the same strengths and is equally effective, often at a lower cost.

Brand Neurontin vs Generic Gabapentin

Both contain the same active ingredient and must meet the same FDA standards for quality, safety, and efficacy. The only significant difference is price: generic gabapentin is typically much less expensive. Many insurance plans prefer or require generics.

When comparing prices, you may see both options. Choose the one that best fits your budget and prescription.

How to Take Neurontin Safely

Always follow your healthcare provider's instructions. Do not start, stop, or change your dose without medical advice. Abruptly stopping gabapentin can cause withdrawal symptoms such as anxiety, insomnia, nausea, and sweating.

1. Take Neurontin exactly as prescribed, usually with or without food.
2. If you miss a dose, take it as soon as you remember unless it is close to your next dose.
3. Do not take a double dose to make up for a missed one.
4. Store at room temperature away from moisture and heat.

Common Side Effects and Precautions

Like all medications, Neurontin may cause side effects. The most common include:

• Dizziness or drowsiness
• Coordination problems
• Fatigue
• Swelling in hands or feet
• Dry mouth

Serious side effects requiring immediate medical attention include mood changes, suicidal thoughts, severe allergic reactions, and difficulty breathing. This is not a complete list. Read the full FDA label or consult your pharmacist.

Important: Gabapentin may interact with opioids, antacids, and alcohol. Tell your doctor about all medications you take.
