The U.S. Food and Drug Administration (FDA) has approved gabapentin for specific medical uses.
What is gabapentin approved to treat?
Gabapentin is approved to treat partial-onset seizures in adults and children 3 years and older with epilepsy [1]. It is also approved for the management of postherpetic neuralgia, a type of nerve pain that can occur after a shingles infection, in adults [1].
Is gabapentin used for anything else?
While gabapentin is FDA-approved for seizures and postherpetic neuralgia, it is frequently prescribed off-label for other conditions [2]. Common off-label uses include restless legs syndrome, anxiety disorders, alcohol withdrawal, and neuropathic pain beyond postherpetic neuralgia [2]. Off-label use means a drug is prescribed for a condition not listed on its official FDA-approved label [2].
How does gabapentin work for seizures?
Gabapentin is thought to work by affecting the release of certain neurotransmitters in the brain. While its exact mechanism of action for seizure control is not fully understood, it is believed to modulate the activity of voltage-gated calcium channels, thereby reducing neuronal excitability [1].
What are the side effects of gabapentin?
Common side effects of gabapentin can include dizziness, drowsiness, fatigue, and coordination problems [3]. Less common but more serious side effects may include suicidal thoughts or behaviors, severe allergic reactions, and changes in vision [3]. Patients should report any new or worsening symptoms to their healthcare provider [3].
When did gabapentin get FDA approval?
Gabapentin was first approved by the FDA in 1993 for adjunctive therapy in the treatment of partial seizures [4]. Its approval for postherpetic neuralgia came later [4].
What are the generic options for gabapentin?
Gabapentin is available as a generic medication, which can affect its pricing and accessibility [5]. The availability of generics means that multiple manufacturers produce the drug, often leading to lower costs compared to brand-name versions [5].
