Neurontin and Ativan are used in very different patients, and the points in common are limited. The main shared element is that both meet regulatory standards for efficacy and safety and benefit from pharmacist oversight.
Key differences
Neurontin belongs to Neurological Medications while Ativan belongs to Anti-anxiety Medications. Indications, mechanisms and target populations differ. The comparison is most useful when a clinician has mentioned both medications and the patient wants to understand where each fits.
Mechanism and action
Neurontin: Gabapentin binds the alpha-2-delta auxiliary subunit of voltage-gated calcium channels in the central nervous system, reducing presynaptic calcium influx and the release of excitatory neurotransmitters such as glutamate… Ativan: Lorazepam binds the benzodiazepine site of the GABA-A receptor and allosterically enhances inhibitory chloride conductance.
When Neurontin is preferred
Neurontin is approved in adults and children aged 3 years and older as adjunctive therapy for partial-onset seizures, and in adults for post-herpetic neuralgia.
When Ativan is preferred
Ativan is approved in adults for the short-term management of anxiety disorders and anxiety-related insomnia.
Frequently asked questions
Is Neurontin or Ativan better? ▾

Can I switch from Neurontin to Ativan? ▾
Switching between Neurontin and Ativan is rarely an appropriate decision since they belong to different classes and treat different conditions. The real question is usually whether the diagnosis calls for one medication or the other — which the prescriber resolves.
Do Neurontin and Ativan have the same side effects? ▾
No — they belong to different classes and have distinct side-effect profiles. Each medication has its own prescribing information.
