The FDA has developed the “Be Safe Rx Campaign” for consumer education and to address the need for caution in purchasing drugs online. Nearly twenty-five percent of people who have purchased drugs online have purchased from a site not associated with any pharmacy or health insurance plan.

Some red flags that could signal a fraudulent online pharmacy: Beware of online pharmacies that are located outside the United States and are not licensed in the United States by a state agency. Another tipoff is an online pharmacy that allows you to buy medicine without a prescription or by asking you to complete an online survey instead of requiring a prescription, or offers very low drug prices that seem too good to be true. Many fake online pharmacies send spam or unsolicited e-mail offering deep discounts on medicine. Be wary of drugs shipped from a foreign country.
