What is Gabapentin 400 mg Tablet?
Gabapentin is a medication that belongs to the anticonvulsant class of drugs. It is primarily used to treat nerve pain, seizures, and restless leg syndrome (RLS). Gabapentin works by affecting the way nerves send signals to the brain, thereby reducing pain and preventing seizures.
Gabapentin is available in different strengths, including 100mg, 300mg, 400mg, 600mg, and 800mg. Among these, Gabapentin 400 mg tablet is commonly prescribed for moderate to severe nerve pain and seizure control.
Uses of Gabapentin 400 mg Tablet
1. Treatment of Neuropathic Pain
Gabapentin 400 mg tablet is highly effective in managing nerve pain caused by conditions such as:
- Diabetic neuropathy (nerve damage due to diabetes)
- Postherpetic neuralgia (nerve pain after shingles)
- Sciatica (pain from compressed nerves in the spine)
- Fibromyalgia (chronic muscle and nerve pain)
2. Epilepsy and Seizure Disorders
Gabapentin is used as an adjunct treatment for partial seizures in adults and children over three years old. It helps control seizures by stabilizing nerve activity in the brain.
3. Restless Leg Syndrome (RLS)
Restless leg syndrome is a condition that causes an uncontrollable urge to move the legs, especially at night. Gabapentin can help alleviate discomfort and improve sleep quality.
4. Migraine Prevention
While not a primary treatment, some doctors prescribe Gabapentin to help reduce the frequency and intensity of migraines.
Dosage and Administration
Gabapentin dosage varies based on the condition being treated, the patient’s response, and medical history. Common dosage guidelines include:
- Nerve pain: Starting dose is 300 mg once daily, gradually increasing to 900-1800 mg per day.
- Seizures: Typically, 300-400 mg is given three times a day (totaling 900-1200 mg per day).
- RLS: A lower dose, such as Gabapentin 100mg or 300mg, is often prescribed initially and adjusted based on effectiveness.
It is important to follow your doctor’s instructions and not exceed the prescribed dose. Gabapentin should be taken with or without food, and doses should be spaced evenly throughout the day.

Drug Interactions with Gabapentin 400 mg Tablet
Gabapentin can interact with several medications, leading to reduced effectiveness or increased risk of side effects. Some notable interactions include:

If you are taking multiple seizure medications, your doctor will adjust doses to prevent excessive drowsiness or other side effects.
