Ambien, the brand name for zolpidem, is a prescription sleep aid used to help individuals with insomnia fall asleep faster and stay asleep through the night. It works by targeting specific brain receptors to promote relaxation and initiate sleep more effectively. In the United States, Ambien is a controlled medication that can only be obtained with a valid prescription from a licensed healthcare provider and must be dispensed through authorized pharmacies. For patients who already hold a prescription, select reputable services offer overnight delivery with rapid processing, ensuring timely access while maintaining safety and regulatory compliance.
