Ambien (zolpidem) is a prescription medication designed to treat insomnia by helping people fall asleep faster. Despite online offers promoting Ambien without a prescription and next-day delivery, acquiring it this way is both illegal and risky. Misuse of Ambien can result in serious side effects, including memory loss, unusual behavior, and dependency. It should only be used under the direction of a licensed medical professional to ensure proper dosing and to monitor for adverse reactions.
