Key takeaways
Quetiapine (Seroquel) and zolpidem (Ambien) 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. Zolpidem, on the other hand, is a GABA A receptor positive modulator used to treat insomnia by slowing down brain activity to help you fall asleep. Quetiapine is not a controlled substance, while zolpidem is a Schedule IV controlled substance due to its potential for misuse and dependency. Quetiapine can cause side effects like weight gain, high blood sugar, and suicidal thoughts, especially in younger people. Zolpidem can cause sleepwalking, sleep driving, and daytime sleepiness, and should only be used short-term. Both medications have generic forms available.
