Head-to-head comparisons of medication uses, side effects, warnings, and more.
Key takeaways
Haldol (haloperidol) and Neurontin (gabapentin) are both prescription medications, but they are used for different conditions and belong to different drug classes. Haldol is a typical antipsychotic used to treat schizophrenia and is available as oral forms and an injection, while Neurontin is an antiepileptic used to treat certain seizures and nerve pain, available in oral forms like tablets, capsules, and liquid. Haldol works by blocking dopamine activity in the brain, which helps reduce hallucinations and delusions, whereas Neurontin's exact mechanism is not fully understood but is thought to calm nerves by mimicking the structure of GABA, a calming brain chemical. Haldol long-acting injection is typically given monthly by a healthcare provider, while Neurontin needs to be taken multiple times a day. Common side effects of Haldol include movement-related issues like abnormal movement in muscles and tremors, whereas Neurontin commonly causes dizziness and sleepiness. Additionally, Haldol can cause abnormal heart rhythms and neuroleptic malignant syndrome as side effects, while Neurontin can raise the risk of suicidal thoughts.
