Head-to-head comparisons of medication uses, side effects, warnings, and more.
Key takeaways
Haloperidol (Haldol) and lorazepam (Ativan) are both prescription medications, but they are used for different conditions and belong to different drug classes. Haloperidol is a typical antipsychotic used primarily to treat schizophrenia and is available as an injection and oral forms. It works by blocking dopamine activity in the brain, which helps reduce hallucinations and delusions. Lorazepam, on the other hand, is a benzodiazepine used for short-term treatment of anxiety and is available in both oral and injectable forms. It works by slowing down brain activity to help control anxiety and stop seizures. Haloperidol injections are typically given monthly and has a lower risk of weight gain but can cause movement-related side effects. Lorazepam can start working within 30 minutes when taken orally but has a risk of dependence and withdrawal symptoms if used long-term. Additionally, lorazepam is a controlled substance due to its potential for misuse, while haloperidol is not. Both medications should be used with caution, especially in older adults and those with certain health conditions.
