What is Gabapentin?

Gabapentin is a prescription medication used to treat epilepsy, restless legs syndrome (RLS), postherpetic neuralgia (PHN), and other neurological conditions. It belongs to a class of drugs known as anticonvulsants that work by blocking certain nerve signals in the brain. In addition to its use for epilepsy and related disorders, gabapentin may also be prescribed for off-label uses such as fibromyalgia, bipolar disorder, and hot flashes.

How Does Gabapentin Work?

Gabapentin works by reducing abnormal electrical activity in the brain. This helps reduce seizures or symptoms of conditions like RLS and PHN. It does this by binding to certain proteins in the brain called calcium channels that control the release of neurotransmitters (chemicals that help carry messages between nerves). By decreasing the release of these neurotransmitters, gabapentin can reduce seizures or relieve pain from PHN.

What Are the Major Side Effects of Gabapentin?

The most common side effects associated with gabapentin are dizziness, drowsiness, fatigue, and headache. These usually resolve within a few days after starting the drug but may persist if the dosage is too high. Other possible side effects include confusion, nausea, vomiting, diarrhea, constipation, blurred vision, eye pain or irritation, dry mouth, muscle twitching or tremors, difficulty speaking or swallowing, anxiety or depression. Rarely reported serious side effects include allergic reactions such as rash or hives; swollen face, throat or tongue; breathing problems; changes in mood or behavior; fever; chills; joint pain; yellowing of skin or eyes; chest pain; swelling of feet or hands; increased urination; unusual bleeding or bruising.

When Should I Not Take Gabapentin?

Additionally, gabapentin should not be taken during pregnancy unless it is deemed absolutely necessary by your doctor due to risks posed to both mother and fetus. You should also avoid taking gabapentin if you have kidney disease since it can accumulate in your body and cause severe adverse reactions. It is important to tell your doctor about all medications you are currently taking before beginning treatment with gabapentin as some drugs may interact with it and increase its toxicity.

What Is the Recommended Dosage for Gabapentin?

The recommended dose for treating epilepsy is typically 300 mg three times per day for adults and 25 mg/kg/day divided into three doses for children ages 3-12 years old. For treating neuropathic pain associated with RLS or PHN the dose may range from 900-1800 mg per day depending on the severity of symptoms. It is important to take gabapentin exactly as directed by your doctor and do not change your dose without consulting them first as this could lead to serious health complications.
