When safely purchasing Ambien on the internet and avoiding fake or illegitimate pharmacies, always only purchase from licensed U.S. pharmacies that are authorized by your state's board of pharmacy, require a doctor's prescription, and have a physical address. Look for a licensed pharmacist to talk to, and make sure they have a secured "https" checkout. You should also be cautious of a website that is not requiring a prescription, or is offering to sell Ambien at a low restricted price, as these may be signs that the medication is either fake, or not safe. If you are not confident with the credentials of the prescription pharmacy, consider reviewing resources from the FDA's BeSafeRx or National Association of Boards of Pharmacy (NABP) before purchasing!
