Head-to-head comparisons of medication uses, side effects, warnings, and more.

Key takeaways

Quetiapine (Seroquel) and lorazepam (Ativan) are both prescription medications, but they are used for different purposes and belong to different drug classes. Quetiapine is an atypical antipsychotic used to treat schizophrenia, bipolar disorder, and as an add-on for depression. It works by balancing chemicals in the brain like dopamine and serotonin. Lorazepam, on the other hand, is a benzodiazepine used for short-term treatment of anxiety and to control seizures. It works by slowing down brain activity. Quetiapine is available in both immediate-release and extended-release oral forms, while lorazepam is available in immediate-release tablets, oral solution, and as an injectable. Quetiapine can cause weight gain and high blood sugar, whereas lorazepam has a risk of dependence and withdrawal symptoms. Additionally, lorazepam is a controlled substance due to its potential for misuse, while quetiapine is not.
