Neurontin is administered as a combination therapy to control or prevent seizures in persons older than three years. The drug is popularly regarded as an antiepileptic. It also relieves adults of neuralgia. Neurontin is available in tablets, capsules, and liquid solutions.

Dosage & Administration

Gabapentin is available in different brands. So, if the physician changes the strength and brand that you’re ingesting and the strength, the dose will also change. Ensure you read the instructions in the medicine guide. 

Neurontin can be ingested with fatty food or on an empty stomach. But capsules and tablets must be swallowed, not chewed. Utilize a syringe or calibrated medicine device to measure the correct quantity of liquid solution. Avoid using an eating spoon because it won’t give the correct measurement.

When dividing Gabapentin tablets, ensure to consume each half at the proper time. Discard an unused half-tablet after twenty-eight days. Don’t discontinue Neurontin without informing a physician because it requires gradual weaning to prevent any adverse effects.
